                                    PART I
Item 1.  Business

(a)  General Development of the Business

Dravo Corporation (the Registrant) was incorporated in Pennsylvania in 1936 to
consolidate several related corporations then operating various elements of a
business started in 1891 by F. R. Dravo.  Its corporate offices are located at
3600 One Oliver Plaza, Pittsburgh, Pennsylvania 15222-2682, and its telephone
number is 412-566-3000.  As used herein, the term Dravo includes its
consolidated subsidiaries unless otherwise indicated.  In December, 1987,
Dravo's Board of Directors approved a major restructuring program which
concentrated Dravo's future direction exclusively on opportunities involving
its natural resources business.  The plan included the sale or other
disposition of the former Engineering and Construction segment, as well as the
sale of the former Materials Handling and Systems segment approved earlier. 
All units scheduled for sale were sold by the end of 1989.  The remainder of
these businesses have been presented as  discontinued operations in the
financial statements.  

Late in 1994, the company sold substantially all the assets and certain
liabilities of Dravo Basic Materials Company, its construction aggregates
subsidiary, to Martin Marietta Materials, Inc. (Martin Marietta).  As a result,
Dravo is now primarily a lime company operating principally in the United
States.  Activities include the production of lime for utility, metallurgical,
pulp and paper, municipal, construction and miscellaneous chemical and
industrial applications.  Operations are principally carried on by a wholly-
owned subsidiary, Dravo Lime Company (Dravo Lime).  All of the properties on
which the company's reserves are located are physically accessible for purposes
of mining and processing limestone into lime.

Dravo Lime, one of the nation's largest lime producers, owns and operates three
integrated lime production facilities, two in Kentucky and one in Alabama.  The
Black River plant in Butler, Kentucky is nearing completion of a two kiln
expansion.  When that expansion is on-line, Dravo Lime's annual quicklime
capacity will total approximately three million tons.

The Maysville facility, a 1,050,000 ton-per-year plant near Maysville,
Kentucky, produces material, marketed under the trade name ThiosorbicR Lime,
that has a product chemistry ideally suited for removing sulphur dioxide from
power plant stack gases.  All of Maysville's output is committed under long-
term contracts with utility companies in the Ohio Valley region.  All contracts
contain provisions for price escalation.  Owned reserves at the Maysville site
are recovered from a mine 950 feet underground and are considered adequate to
sustain the current three kiln production in excess of thirty years.  Dravo
Lime also holds options on additional limestone reserves to sustain production
for an additional thirty year period.

With the completion of the current two kiln expansion, Dravo Lime's Black River
facility will be an integrated ThiosorbicR and high calcium quicklime, bulk and
bagged hydrated lime facility.  Located along the Ohio River at Butler,
Kentucky, Black River will have an annual quicklime capacity of 1,350,000 tons-
per-year.  Of that total, in excess of seventy percent is committed to utility
companies and steel producers under contracts with price escalation provisions. 
Limestone 
                                      -3-
<PAGE>
reserves at Black River are recovered from a 600-feet-deep underground mine. 
At Black River's expanded rate of capacity, reserves are considered adequate to
sustain production levels for more than seventy-five years.  

The company's Longview facility, located near Birmingham, Alabama, is an
integrated facility as well that produces high calcium quicklime, and bulk and
bagged hydrated lime from owned limestone reserves.  At this plant, Dravo Lime
also produces dolomitic quicklime from limestone purchased from a nearby
dolomitic stone quarry.  Due to its material handling and storage capabilities
and its ability to produce high calcium and dolomitic lime, the Longview
facility is able to custom blend quicklime to its customers' chemical
specifications.  In April, 1991, Longview completed an expansion that increased
its annual production capacity to approximately 570,000 tons per year.  The
additional production has been used to meet the needs of long-term contracts
for precipitated calcium carbonate, a product used by the pulp and paper
industry.  The remainder of Longview's production is marketed to the full range
of traditional lime markets.  Limestone at the Longview operation comes from an
above-ground quarry with recoverable reserves estimated to last in excess of
twenty years at the current production rate.  Ultimately, Dravo Lime expects to
convert Longview to an underground mine, providing access to additional
reserves sufficient to support current production rates for over sixty years.  

In conjunction with the sale of Dravo Basic Materials' assets to Martin
Marietta, Dravo Lime entered into agreements appointing Martin Marietta the
exclusive distributor of aggregate by-products produced by Dravo Lime during
the lime production process.  As part of the distributorship agreement covering
Dravo Lime's Longview facility, an aggregates processing facility is being
constructed that will make available between 500,000 and 1,000,000 tons of
aggregates annually for purchase by Martin Marietta.  An additional benefit of
this installation will be a reduction in the cost Dravo Lime otherwise would
have incurred to recover the high calcium limestone reserves that lie below the
aggregate quality material.

Dravo Lime products are distributed through quicklime distribution terminals in
Aliquippa, Butler and Elizabeth, Pennsylvania; Porterfield, Ohio; Brunswick and
Savannah, Georgia; and Jacksonville, Fort Lauderdale and Sanford, Florida.  At
Baton Rouge, Louisiana, Dravo Lime owns and operates a lime hydration and
bagging facility from which quicklime, and bulk and bagged hydrated lime
products are distributed.

(b)  Competitive Conditions

Dravo encounters competition at all its operations but believes that its
experience, its strategically located reserves and its technical expertise in
the flue gas desulfurization industry give it certain competitive advantages. 
Dravo's research and development expenditures were $4.4 million in 1994 and
$4.2 million in 1993.  Research and development spending in 1995 is expected to
exceed $3.2 million.  The company expects the research, much of which is being
conducted jointly with utility customers, to lower both the capital and
operating costs 

                                      -4-
<PAGE>
associated with Dravo's proprietary ThiosorbicR scrubbing technology.  Other
research projects are aimed at developing proprietary reagents for use in
reducing stack gas emissions and at recovering and processing saleable by-
products.  Dravo believes that in this field its long-term contracts,
accumulated experience and technical skill represent significant competitive
advantages.

Several firms with which Dravo competes have comparable resources and income. 
Dravo competes with other firms for qualified professional personnel,
particularly those with technical skills.

(c)  Corporate Development

Dravo's corporate development policy encompasses growth through investment in
existing businesses, internal development and acquisition.  Additionally, to
the extent that business units no longer meet management's long-term
profitability performance criteria and business strategies, or do not
contribute significantly to corporate objectives, a policy of divestiture is
followed.

Continuing operations of Dravo Corporation, which are principally domestic in
nature, function in one segment, a natural resource business, involved in the
production, processing and supply of lime for environmental, metallurgical,
pulp and paper, municipal, construction and miscellaneous chemical and
industrial applications.  Dravo's position as the world's leading producer of
lime for flue gas desulfurization applications was enhanced by the passage of
the 1990 Clean Air Act Amendments.

Item 3.  Legal Proceedings


The company has been notified by the U. S. Environmental Protection Agency
(EPA) that the EPA considers the company as a potentially responsible party
(PRP) for soil and groundwater contamination at four subsites in or around
Hastings, Nebraska.  The Colorado Avenue subsite includes property on which
the company formerly operated a fabrication facility.  For this subsite, the
EPA has issued, pursuant to the Comprehensive Environmental Response,
Compensation and Liability Act, administrative orders to the company and two
other PRPs which require them to provide interim remedies for soil and
groundwater contamination.  The company has been complying with these orders
while reserving its right to seek reimbursement from the United States for its
costs if it is determined the company is not liable for response costs or if
it is required to incur costs because of arbitrary, capricious or unreasonable
requirements imposed by EPA.

The EPA has taken no legal action with respect to its demand that the company
and the other PRPs pay its past response costs.  A total of five parties have
been named by the EPA as PRPs at this subsite, but two of them have been
granted de minimis status.  The company believes other persons should also be
named as PRPs.

The company, along with a number of others, is also considered a PRP with
respect to subsites at the municipally owned North and South Landfills in
Hastings, Nebraska.  The North Landfill closed before the company commenced
operations in Hastings, Nebraska.  A predecessor may have used this landfill
to dispose of waste materials, but there is no evidence known to the company
that these materials were hazardous.  Moreover, Dravo believes the operations
of Dravo's predecessor which might have generated the type of hazardous
substances found at this landfill did not begin until after this landfill was
closed.  On December 31, 1991 the EPA issued a formal demand to the company
and other PRPs for reimbursement of costs the EPA has incurred at the North
Landfill and has also solicited an offer from the company and the other PRPs
to conduct or finance remedial work at this subsite for both soil and
groundwater contamination.  The company has rejected the EPA's demand to
reimburse the EPA for its costs and decided not to submit the offer requested. 
No PRP at this subsite has agreed to pay the EPA's response costs.  Other
PRPs, including the local municipality, however, have agreed to perform the
remedial investigation and to design soil and groundwater remedies at this
subsite.  EPA has not completed the remedial investigation with respect to the
South Landfill subsite, and it is not evident to the company that remedial
work is warranted.  In January, 1994 the EPA sent a specific notice to the
company that the EPA considered it and three other parties (including the City
of Hastings) PRPs at this subsite.  At this subsite, the company has
preliminarily concluded that the City of Hastings is primarily responsible for
a proper closure of the South Landfill pursuant to state landfill closure
requirements and that a proper closure might alleviate any release of
contaminants from the landfill.

The fourth subsite (NAD subsite) is a former naval ammunition depot which was
subsequently converted to an industrial park in the 1960s.  The company and
its predecessor also owned and operated a fabrication facility in this
industrial park.  To date, the company's investigation indicates that it did
not cause the release of hazardous substances at this subsite during the time
it owned and operated the facility.  The United States Army Corps of Engineers
has undertaken to conduct the remediation of this subsite.

                                      -7-
<PAGE>
In addition to subsite cleanup, the EPA is seeking a cleanup of area-wide
contamination associated with all of the subsites in and around Hastings,
Nebraska.  The company, along with other Hastings PRPs, has recommended that
the EPA adopt institutional controls as the area-wide remedy in Hastings and
the final subsite remedy.  EPA has indicated some interest in this proposal
but has decided to first conduct an area-wide remedial investigation before
choosing a remedy.

On August 10, 1992, the company filed suit in the Alabama District Court
against its primary general liability insurers, Hartford Accident and
Indemnity Company and Liberty Mutual Insurance Company, and one of its
predecessor's insurers, Bituminous Casualty Company, seeking a declaratory
judgment that the company is entitled to a defense and indemnity under its
contracts of insurance (including certain excess policies provided by
Hartford).  The company has settled its claim against Bituminous, but the
company's claims against Hartford and Liberty Mutual are still being
litigated.  The company has notified its primary and excess general liability
carriers, as well as its predecessor's carriers, of the potential claims at
the North Landfill, South Landfill and NAD subsites.

On February 21, 1990, the company filed suit against Continental Energy
Associates (CEA), the owner of a cogeneration facility in Hazleton,
Pennsylvania, Continental Cogeneration Corporation (CCC), the owner's general
partner, and Swiss Bank Corporation, the project's lender.  The company claims
damages for breach of contract and unjust enrichment arising out of the
termination of the company's contract to construct, as part of the facility, a
coal gasification plant.  On February 23, 1990, CEA and CCC filed suit against
the company which, as amended, seeks damages for breach of contract, negligent
misrepresentation, fraud and tortious interference with the contract of
surety.  The lawsuits have been consolidated in the Court of Common Pleas of
Luzerne County, Pennsylvania.

On November 14, 1994, during the pendency of discovery in these lawsuits, CEA
filed for Chapter 11 bankruptcy protection in the United States Bankruptcy
Court for the Middle District of Pennsylvania.  The company has been
identified as an unsecured creditor in that proceeding.  On December 2, 1994,
CCC also filed for Chapter 11 bankruptcy protection in the same court.  The
bankruptcy filings of both CEA and CCC have stayed the consolidated Luzerne
County lawsuits pursuant to the applicable provisions of the Bankruptcy Code.

In January, 1995, the Bankruptcy Court entered an order approving non-binding
mediation of these lawsuits with the company.  An initial mediation session
held in early March, 1995, did not result in resolution of the lawsuits.

                      Description of Dravo Capital Stock

General

Under its Restated Articles of Incorporation ("the Articles"), as amended,
Dravo is authorized to issue 1,878,870 shares of preference stock, par value
$1.00 per share, and 35,000,000 shares of common stock, par value $1.00 per
share.  At December 31, 1994 issued preference and common shares were 228,386
and 14,985,839, respectively.

The Board of Directors has by resolutions established four series of
preference stock:  $2.20 Cumulative Convertible Series A Preference Stock
("Series A Preference Stock"), consisting of 26,817 shares, issued on
September 1, 1970; $2.475 Cumulative Convertible Series B Preference Stock
("Series B Preference Stock"), consisting of 165,516 shares, issued on June
12, 1973; Series C Preference Stock consisting of 200,000 shares, which are
issuable pursuant to the exercise of the rights to purchase stock described
below; and Series D Cumulative Convertible Exchangeable Preference Stock
("Series D Preference Stock") consisting of 200,000 shares, issued on
September 21, 1988.  All of the shares of Series A Preference Stock were
converted into shares of common stock on April 2, 1978.  Presently there are
28,386 shares of Series B Preference Stock and 200,000 shares of Series D
Preference Stock issued and outstanding.  No shares of Series C Preference
Stock have been issued or are outstanding.  Other series of preference stock
may be created by resolutions of the Board of Directors with such dividend,
liquidation, redemption, sinking fund and conversion rights as shall be
specified therein.

Dividend Rights 

The holders of the preference stock are entitled to cumulative dividends,
payable quarterly, which must be paid and the next quarterly dividend set
apart before any dividends (except dividends in common stock or any other
stock ranking after


                                      -9-
<PAGE>
the preference stocks as to dividends and assets) are declared, or paid, or
monies set apart for the payment of dividends on any class of stock ranking
after the preference stock as to dividends or assets.  The rate of dividends
payable upon the Series B Preference Stock is $2.475 per annum.  The rate of
dividends payable upon the Series C Preference Stock is an amount per share
(rounded to the nearest cent) equal to the greater of $10.00 or 100 times the
aggregate per share amount of all cash and non-cash dividends or other
distributions, other than a dividend or distribution payable in shares of
common stock, paid on the common stock in the immediately preceding quarter,
subject to adjustment in certain events.  The rate of dividends payable upon
the Series D Preference Stock is 12.35 percent per annum or $12.35 per share,
which rate shall be increased by 2 percent per annum if such dividends are not
paid on any quarterly dividend payment date until accrued and unpaid dividends
on the Series D Preference Stock are paid.

The holders of the common stock are entitled to such dividends as may be
declared by the Board of Directors out of assets properly available for that
purpose.  No common stock dividends have been declared since April, 1987.

Other information required by this item is incorporated by reference to the
information set forth under the caption "Note 5:  Notes Payable", in the Notes
to Consolidated Financial Statements on pages 30 and 31 of the 1994 Annual
Report to Shareholders which accompanies this report.

Voting Rights

Each share of the common stock and the preference stock is entitled to one
vote, which is cumulative in the election of directors.  The Board of
Directors is divided into three classes, and approximately one third of the
directors are elected each year for three year terms.  The effect of such
classification of the Board is to increase the number of shares, voted
cumulatively, necessary to elect directors.  If dividends on the preference
stock shall be unpaid or in arrears for six quarterly dividend periods, the
holders of the preference stock voting as a class shall have the right to
elect two additional directors.

Liquidation Rights

In the event of the voluntary or involuntary liquidation or dissolution of
Dravo, or the sale or other disposition of substantially all of its assets,
the holders of the Series B Preference Stock shall be entitled to receive the
sum of $55 per share plus all accumulated and unpaid dividends thereon; the
holders of Series C Preference Stock shall be entitled to receive $100 per
share plus all accrued and unpaid dividends plus an amount equal to the
holder's pro rata share of the amount that would be available for distribution
after payment of all liabilities, 

                                     -10-
<PAGE>
liquidation preferences and a distribution on the common stock, if any, as
determined according to a formula; and the holders of Series D Preference
Stock shall be entitled to receive $100 per share plus all accumulated and
unpaid dividends thereon.  The holders of any other series of preference stock
which may be issued shall be entitled to receive the amounts provided for in
the resolutions creating such series.  The holders of the common stock shall
share ratably in the remaining assets, if any.

No Preemptive Rights and Non-assessability

No preemptive rights attach to the common stock or the preference stock. 
Neither the holders of the common stock nor the preference stock are liable to
further calls or assessment by Dravo.

Redemption and Sinking Fund Provisions

There are no redemption provisions with respect to the common stock.  The
Series B Preference Stock may be redeemed, in whole or in part, at the option
of Dravo, on not less than 60 days notice, on any quarterly dividend payment
date by the payment of $55 per share and all accumulated and unpaid dividends
to the redemption date.  The Series C Preference Stock may be redeemed as a
whole, but not in part, at the option of Dravo, at any time, at a cash price
per share based upon the average market value, as defined and adjusted, of the
common stock plus all accrued but unpaid dividends.  The Series D Preference
Stock may be redeemed in whole or in part at the option of Dravo at any time
after September 21, 1996, by the payment of $100 per share and all accumulated
and unpaid dividends to the redemption date, so long as the current market
price (as defined in the Certificate of Designations, Preferences and Rights
for the Series D Preference Stock) of the common stock on the date the Board
decides to redeem the shares is at least 175 percent of the then effective
conversion price for the Series D Preference Stock.  Commencing on the first
quarterly dividend payment date after September 21, 1998 and annually
thereafter, Dravo is required to redeem 50,000 shares of Series D Preference
Stock in cash at the redemption price of $100 per share plus all accumulated
and unpaid dividends.  Dravo is also required (unless certain conditions are
met) to redeem all of the then outstanding shares of Series D Preference Stock
in cash at $100 per share plus all accumulated and unpaid dividends (a) if
Dravo declares or pays or sets apart for payment any dividends or makes any
other distribution in cash or other property on or in respect of the common
stock or any other class or series of the capital stock of Dravo ranking
junior to the Series D Preference Stock as to payment of dividends ("Junior
Dividend Stock"), or sets apart money for any sinking fund or analogous fund
for the redemption or purchase of any Junior Dividend Stock and (b) upon any
merger or consolidation of Dravo if, in connection therewith, the holders of
the common stock receive cash, debt instruments or preference stock of the
surviving entity which ranks on a parity with or senior to the Series D
Preference stock with respect to liquidation, dissolution or winding up or
dividends.  There are no sinking fund provisions with respect to the common
stock or the Series B Preference Stock, Series C Preference Stock or Series D
Preference Stock.

Conversion

The Series B Preference Stock is presently convertible at any time prior to
redemption at the option of the holder into common stock on the basis of 3.216
shares of common stock for each share of Series B Preference Stock, subject to
equitable adjustment in the event of certain changes affecting the common
stock.  The Series D Preference Stock is presently convertible at any time
prior to redemption at the option of the holder into common stock on the basis
of 8.0 shares of common stock for each share of Series D Preference Stock,
subject to adjustment in the event of certain changes affecting the common
stock.  The Series D Preference Stock is convertible or exchangeable in whole
at any time by Dravo for an equal face amount of Dravo Senior Subordinated
Convertible Notes due September 21, 2001 containing the same conversion
rights, transfer restrictions and other terms (other than voting rights) as
the Series D Preference Stock.  There are no conversion rights with respect to
the Series C Preference Stock or the common stock.

Rights to Purchase Series C Preference Stock

The Series C Preference Stock is issuable pursuant to the exercise of rights
to purchase Series C Preference Stock.  On April 4, 1986, the Board of
Directors declared a distribution of one right for each outstanding share of
common stock to shareholders of record at the close of business on April 17,
1986 (the "Record Date") and with respect to each share of common stock that
may be issued by Dravo prior to the Distribution Date described below or the
earlier redemption or expiration of the rights.  Each right entitles the
registered holder, following the occurrence of certain events described below,
to purchase from Dravo a unit consisting of one one-hundredth of a share (a
"Unit") of Series C Preference Stock at a purchase price of $60 per Unit,
subject to adjustment (the "Purchase Price").  The descriptions and terms of
the rights are set forth in a rights agreement (the "Rights Agreement")
between Dravo and PNC Bank, N. A. (formerly Pittsburgh National Bank), as the
rights agent.

Initially, the rights will be attached to all common stock certificates
representing shares then outstanding, and no separate rights certificates will
be distributed.  The rights will separate from the common stock and a
distribution date will occur upon the earlier of (a) 10 days following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person") has acquired, or obtained the right to acquire,
beneficial ownership of 20 percent or more of the outstanding shares of common
stock of Dravo (the "Stock Acquisition Date"), or (b) 10 business days
following the commencement of a tender offer or exchange offer that would
result in a person or group beneficially owning 30 percent or more of such
outstanding shares of common stock.  Until the distribution date, (i) the
rights will be evidenced by the common stock certificates and will be
transferred with and only with such common stock certificates, (ii) new common
stock certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference, and (iii) the surrender for
transfer of any certificate for common stock outstanding will also constitute
the transfer of the rights associated with the common stock represented by
such certificate. 

                                     -12-
<PAGE>
The rights are not exercisable until the distribution date and will expire at
the close of business on April 17, 1996, unless earlier redeemed by Dravo as
described below.

In the event that, at any time following the distribution date, (a) Dravo is
the surviving corporation in a merger with an Acquiring Person and its common
stock is not changed or exchanged, (b) an Acquiring Person becomes the
beneficial owner of 30 percent or more of the then outstanding shares of
common stock, (c) an Acquiring Person engages in one or more "self-dealing"
transactions as set forth in the Rights Agreement, or (d) during such time as
there is an Acquiring Person, an event occurs which results in such Acquiring
Person's ownership interest being increased by more than one percent (e.g., a
reclassification of securities, reverse stock split or recapitalization of
Dravo), each holder of a right will thereafter have the right to receive, upon
exercise, common stock (or, in certain circumstances, cash, property or other
securities of Dravo) having a value equal to two times the Purchase Price of
the right.  Notwithstanding any of the foregoing, (i) rights are not
exercisable following the occurrence of any of the events set forth in this
paragraph until such time as the rights are no longer redeemable by Dravo as
set forth below, and (ii) following the occurrence of any of the events set
forth above, all rights that are, or (under certain circumstances specified in
the Rights Agreement) were, beneficially owned by any Acquiring Person will be
null and void.

In the event that, at any time following the stock acquisition date, (i) Dravo
is acquired in a merger or other business combination transaction in which
Dravo is not the surviving corporation (other than a merger described in the
preceding paragraph), or (ii) 50 percent or more of Dravo assets or earning
power is sold or transferred, each holder of a right (except rights which
previously have been voided as set forth above) shall thereafter have the
right to receive, upon exercise, common stock of the acquiring company having
a value equal to two times the exercise price of the right.  The events set
forth in this paragraph and in the preceding paragraph are referred to as the
"Triggering Events."

The Purchase Price payable, and the number of units of Series C Preference
Stock or other securities or property issuable, upon exercise of the rights
are subject to adjustment from time to time to prevent dilution.  No
fractional units may be issued and, in lieu thereof, an adjustment in cash may
be made based on the market price of the Series C Preference Stock on the last
trading date prior to the date of exercise.

At any time until ten days following the stock acquisition date, Dravo may
redeem the rights in whole, but not in part, at a price of $.01 per right. 
Under certain circumstances set forth in the Rights Agreement, the decision to
redeem shall require the concurrence of a majority of the continuing
directors, as defined.  After the redemption period has expired and prior to
the occurrence of a Triggering Event, Dravo's right of redemption may be
reinstated if an Acquiring Person reduces his beneficial ownership to 10
percent or less of the outstanding  

                                     -13-
<PAGE>
shares of common stock in a transaction or series of transactions not
involving Dravo.  Immediately upon action of the Board of Directors ordering
redemption of the rights, with, where required, the concurrence of the
continuing directors, the rights will terminate and the only right of the
holders of rights will be to receive the $.01 redemption price.

Until a right is exercised, the holder thereof, as such, will have no rights
as a shareholder of Dravo, including, without limitation, the right to vote or
to receive dividends.

Other than those provisions relating to the principal economic terms of the
rights, any of the provisions of the Rights Agreement may be amended by the
Board of Directors of Dravo prior to the distribution date.  Thereafter, the
provisions of the Rights Agreement may be amended by the Board (in certain
circumstances, with the concurrence of the continuing directors) in order to
cure any ambiguity, to make changes which do not adversely affect the
interests of holders of rights (excluding the interests of any Acquiring
Person), to suspend the effectiveness of the provision of the Rights Agreement
pursuant to which certain rights become void as described above, or to shorten
or lengthen any time period under the Rights Agreement; provided, however,
that no amendment to adjust the time period governing redemption shall be made
at such time as the rights are not redeemable.

The rights may have the effect of preventing or discouraging some attempts to
acquire control of Dravo.  The rights could cause substantial dilution to a
person or group that attempts to acquire control of Dravo on terms not
approved by its Board of Directors, unless the offer is conditioned on a
substantial percentage of rights being tendered to and acquired by the
Acquiring Person.  The rights should not interfere with any merger or other
business combination approved by the Board of Directors prior to the
expiration of the redemption period since the rights may be redeemed by Dravo
prior to the expiration of such period and Dravo may suspend the provisions
that in certain circumstances prevent an Acquiring Person from exercising its
rights.  The rights could interfere with a negotiated transaction after an
acquisition of 20 percent or more voting power if the rights were not
redeemed.  The rights will not prevent a holder of a controlling interest from
exercising control over Dravo.

A copy of the Rights Agreement has been filed with the Securities and Exchange
Commission as an Exhibit to a Report on Form 8-K.  A copy of the Rights
Agreement is available free of charge from Dravo upon the request of any
shareholder.  This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights
Agreement.

Other Information

Dravo may purchase shares of the preference stock whether or not any dividend
arrearage shall exist with respect thereto, and may hold and dispose of such
shares in such manner as it may elect.

                         INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
Dravo Corporation:

Under date of February 10, 1995, we reported on the consolidated balance
sheets of Dravo Corporation and subsidiaries as of December 31, 1994, and
1993, and the related consolidated statements of operations, retained
earnings, and cash flows for each of the years in the three-year period ended
December 31, 1994, as contained in the 1994 annual report to shareholders.  As
discussed in Notes 10 and 13 to the consolidated financial statements, the
company adopted the method of accounting for postemployment benefits
prescribed by Statement of Financial Accounting Standards No. 112 in 1994 and
the methods of accounting for postretirement benefits other than pensions and
income taxes prescribed by Statements of Financial Accounting Standard Nos.
106 and 109, respectively, in 1993.  These consolidated financial statements
and our report thereon are incorporated by reference in the annual report on
Form 10-K for the year 1994.  In connection with our audits of the
aforementioned consolidated financial statements, we also have audited the
related financial statement schedule as listed in answer to Item 14(a)(2). 
The financial statement schedule is the responsibility of the company's
management.  Our responsibility is to express an opinion on the financial
statement schedule based on our audits.

In our opinion, such financial statement schedule, when considered in relation
to the basic consolidated financial statements taken as a whole, present
fairly, in all material respects, the information set forth therein.

Our audit report on the consolidated financial statements of Dravo Corporation
and subsidiaries referred to above contains an explanatory paragraph that
states that a lawsuit and certain claims and assertions have been brought
against the company for contract disputes and environmental costs, the outcome
of which presently cannot be determined.

Note 2:  Income Taxes

The company adopted Statement of Financial Accounting Standards No. 109
"Accounting for Income Taxes" (SFAS 109) effective January 1, 1993.  The
cumulative effect of this change in accounting for income taxes of $276,000 is
determined as of January 1, 1993 and is reported separately in the Statements
of Operations for the year ended December 31, 1993.  Prior years financial
statements were not restated to apply the provisions of SFAS 109.

Dravo Corporation files a consolidated federal income tax return which
includes the parent and consolidated subsidiaries.  Dravo Corporation parent
company financial statements recognize current income tax benefits to the
extent the benefits are offset by current income tax liabilities of the
consolidated subsidiaries.  Long-term deferred income tax benefits are
recognized to the extent that it is more likely than not that the company will
generate sufficient consolidated taxable income to utilize net operating loss
carryforwards prior to their expiration.

 </TABLE>
Management believes it is more likely than not that the net deferred tax asset
of $24.9 million will be realized through the reversal of temporary
differences and through its subsidiaries future income.  In order to fully
realize the net deferred tax asset, the parent company and its subsidiaries
will need to generate future taxable income of approximately $73.2 million
prior to the expiration of its net operating loss carryforwards.  There can be
no assurance, however, that the parent, or its subsidiaries, will generate any
earnings or any specific level of continued earnings.

                      As Amended January 1, 1995

                               ARTICLE I
                          Board of Directors

     SECTION 1.     The Board of Directors shall consist of not less
than seven and not more than twelve persons to be elected by the
shareholders as herein provided, the exact number to be determined from
time to time by proper resolution of the Board of Directors. The
Directors shall be classified with respect to the time during which
they shall severally hold office, by dividing them into three classes,
each consisting as nearly as possible of the same number of Directors.
At each annual meeting of the shareholders, Directors in the number for
those whose terms then expire shall be elected to serve for terms of
three years, except that the number of Directors to be elected to such
terms shall be adjusted if the number of Directors shall have been
decreased as provided herein so as to eliminate the place of a Director
whose term then expires.

     Nominations for election to the Board of Directors may be made by
the Board of Directors or by any shareholder of the Corporation
entitled to notice of, and to vote at, any meeting called for the
election of Directors. Nominations, other than those made by or on
behalf of the Board of Directors of the Corporation, shall be noticed
in writing and shall be received by the Secretary of the Corporation
not later than (i) with respect to an election of directors to be held
at an annual meeting of shareholders, ninety (90) days prior to the
anniversary date of the immediately preceding annual meeting, and (ii)
with respect to an election of directors to be held at a special
meeting of shareholders, the close of business on the fifteenth (15th)
day following the date on which notice of such meeting is first given
to shareholders or public disclosure of the meeting is made. Such
notification shall contain the following information to the extent
known to the notifying shareholder: (a) the name and residence address
of each proposed nominee and of the notifying shareholder; (b) the
principal occupation of each proposed nominee; (c) a representation
that the notifying shareholder intends to appear in person or by proxy
at the meeting to nominate the person or persons specified in the
notice; (d) the total number of shares of the Corporation that will be
voted for each proposed nominee; (e) the total number of shares of the
Corporation owned by the notifying shareholder; (f) a description of
all arrangements or understandings between the notifying shareholder
and each nominee and any other person or persons (naming such person or
persons) relating to such nomination or nominations by the notifying
shareholder; (g) such other information regarding each nominee proposed
by such shareholder as would be required to be included in a proxy
statement filed with the Securities and Exchange Commission; and (h)
the consent of each nominee to serve as a director of the Corporation 
if so elected. If the information submitted to the Corporation within
the time prescribed above is determined by the Chairman of the Board of
the Corporation to be deficient in any manner, the Chairman shall
advise the notifying shareholder in writing of such deficiencies not

                                                                 Page 2
                                                                By-Laws


later than the close of business on the fifth (5th) day following the
date that the Corporation first received written notice of the
nomination made by the notifying shareholder. The notifying shareholder
must thereafter cure such deficiencies by sending a revised
notification to the Secretary of the Corporation setting forth the
required information which must be received by the Secretary in writing
not later than the fifth (5th) day following the date that the
notifying shareholder received notice from the Corporation of the
deficiencies in the notifying shareholder's written nomination.
Notwithstanding the above, these nominating procedures shall not apply
to any special meeting of the shareholders of the Corporation called
for the election of directors for which notice of the meeting was not
given to shareholders at least twenty (20) days prior to the meeting.
The chairman may disregard and refuse to recognize any nomination
determined by him not to have been made in accordance with the
foregoing procedures.

     If a vacancy occurs in the Board of Directors from any cause,
including any increase in the number of Directors in the manner
prescribed in this Section, a majority of the remaining members of the
Board of Directors, though less than a quorum, shall have the power to
elect a Director to fill such vacancy to serve for the balance of the
unexpired term of the vacating director and until his or her successor
has been elected and qualified.

     In the case of an increase in the number of Directors in the
manner specified in this Section, the additional offices so created
shall be assigned by the Board of Directors to the appropriate class so
that the three classes shall continue to consist, as nearly as
possible, of the same number of Directors.

     At any shareholders' meeting at which Directors are to be elected,
separate elections shall be held for the Directors of each class then
to be elected.

     The Directors shall hold office during the terms for which they
have been elected and until their successors are elected and qualified.

     SECTION 2.     The Board of Directors may, by resolution adopted
by a majority of the whole Board, designate one or more committees,
each committee to consist of two or more of the Directors of the
Corporation. Standing committees shall include the Audit and Finance
Committee and the Compensation and Nominating Committee, each of which
shall be comprised exclusively of Directors who are not current
employees of the Corporation.

     SECTION 3.     The Board of Directors, as soon as reasonably
possible after each annual meeting of shareholders, shall hold a
meeting to organize, elect officers of the Corporation and transact
other business.

     Regular meetings of the Board of Directors may be held without
notice at such time and place as shall from time to time be determined
by the Board of Directors and may be adjourned by the members present
to any other time and place.

     Special meetings may be called at any time by the chief executive
officer or any two members of the Board of Directors upon at least 24
hours' notice, which need not be in writing.

     A majority of the Directors in office shall constitute a quorum
for the transaction of business.

     If all the Directors shall severally or collectively consent in
writing to any action to be taken by the Corporation, such action shall
be as valid corporate action as though it had been authorized at a
meeting of the Board of Directors.

     One or more Directors may participate in a meeting of the Board of
Directors, or of a committee thereof, by means of conference telephone
or similar communications equipment by means of which all persons
participating in the meeting can hear each other.

     SECTION 4.     The Board of Directors shall have the right to
adopt such rules and regulations for the conduct of business, and from
time to time alter and amend the same, as to them may seem proper.

     SECTION 5.     The Board of Directors (or the Compensation
Committee by delegation from the Board), shall fix the compensation of
the officers of the Corporation and such other employees who are
designated by the Board of Directors as holding major positions of
authority in the Corporation.

(as a witness or otherwise) in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative and whether or not by or in the right of the Corporation
or otherwise (hereafter a "proceeding"), by reason of the fact that he
or she is or was a Director or officer or employee of the Corporation,
or is or was serving at the request of the Corporation as a Director,
officer or trustee or employee of another corporation, partnership,
joint venture, trust or other enterprise, including service with
respect to an employee benefit plan, or by reason of any action alleged
to have been taken or not taken by him or her while acting in any such
capacity, against expenses (including attorneys' fees) and all
liability and loss, including  judgments,  fines,  ERISA  excise  taxes 
and  penalties and amounts paid or to be paid in settlement (whether 
with or without court approval), actually and reasonable incurred by
him or her in connection with such threatened, pending or completed
action, suit or proceeding, except to the extent prohibited by law as
the same exists or may hereafter be amended (except in the case of any
such amendment which has the effect of narrowing indemnification rights
that the Corporation was permitted to provide prior to such amendment);
provided, however, that except with respect to claims described in
Section 2 hereof, the Corporation shall indemnify any such person
seeking indemnification in connection with a proceeding (or part
thereof), initiated by such person only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.
Subject to the foregoing indemnification, the right to indemnification
conferred in this Section shall include the right to be paid by the
Corporation expenses incurred; provided, however, that to the extent
required by law, the payment of such expenses in advance of the final
disposition of a proceeding shall be made only upon receipt of an
undertaking by or on behalf of such person to repay such amounts if it
shall ultimately be determined that he or she is not entitled to be
indemnified under this Article or otherwise.

     SECTION 2.     If a claim under Section 1 is not paid in full by
the Corporation within forty-five (45) days after a written claim has
been received by the Corporation, the claimant may, at any time
thereafter, bring suit against the Corporation to recover the unpaid
amount of the claim. The claimant shall also be entitled to be paid the
expenses of prosecuting such claim to the extent he or she is
successful in whole or in part on the merits or otherwise in
establishing his or her right to indemnification or to the advancement
of expenses.

action in his or her official capacity and as to action in any other
capacity while holding that office.

otherwise secure or insure in any manner its indemnification
obligations, including its obligation to advance expenses, whether
arising under or pursuant to this Article or otherwise.

     SECTION 5.     The Corporation shall have the express authority to
enter into such agreements as the Board of Directors deem appropriate

present or future Directors, officers and employees of the Corporation
in connection with their service to, or status with, the Corporation or
any other corporation, partnership, joint venture, trust or other
enterprise, including any employee benefit plan, for whom such person
is serving at the request of the Corporation.

     SECTION 6.     The right to indemnification, including the right
to the advancement of expenses provided herein, shall be a contract
right, shall continue as to a person who has ceased to be a director,
officer, employee, or to serve in any other of the capacities described
herein, and shall inure to the benefit of the heirs, executors and
administrators of such person. Notwithstanding any amendment,
alteration or repeal of this Article or any of its provisions or the
adoption of any provision inconsistent with this Article or any of its
provisions, any person who is or was a director, officer or employee or
is or was serving at the request of the Corporation as a director,
officer, employee, or trustee of another corporation or of a
partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, shall be entitled to
indemnification, including the right to the advancement of expenses, in
accordance with the provisions hereof and thereof with respect to any
action taken or omitted prior to such amendment, alteration or repeal
or the adoption of such inconsistent provision except to the extent
such amendment, alteration, repeal or inconsistent provisions provides
broader rights with respect to indemnification, including the
advancement of expenses, than the Corporation was permitted to provide
prior to the amendment, alteration, repeal, or the adoption of such
inconsistent provision or to the extent otherwise prescribed by law.

Dravo Corporation
Incentive Compensation Plan
(Revised January 1995)

The Dravo Corporation Incentive Compensation Plan provides senior
managers and other key employees the opportunity to earn incentive income
each year by achieving or surpassing predetermined, preapproved
objectives.  

Objectives

The objectives of the Incentive Compensation Plan are to:

*  Promote individual ownership and accountability in the ongoing success
   of the corporation, while focusing team efforts on overall corporate
   earnings objectives.
      
*  Encourage and reward management achievements that contribute to the
   value of the corporation.

*  Communicate key corporate and divisional priorities through the plan.

*  Provide senior managers and other key employees with a competitive
   compensation opportunity. 
Plan Summary

The Dravo Corporation Incentive Compensation Plan (ICP) is a target incentive
plan that provides for the establishment of target, threshold and optimum
incentive awards based upon performance against specific predetermined
performance objectives.  Prior to the beginning of each plan year, target,
threshold and optimum performance levels will be established and approved for
Corporate and Dravo Lime divisional performance.  Those employees who
function across divisional locations will have a single Corporate component
(100%).  Those who are assigned to an individual operating unit will have both a
Corporate component (70%) and a Divisional component (30%). 

At the beginning of each year each participant will be provided with a
Participant's Guide, which will give them an overview of the plan and specify
their target award and award components.

<PAGE>                             10(iv)-1

Shareholder Protection Provisions

To assure that ICP awards are related to acceptable corporate earnings, the
following shareholder protection provisions will apply:

*     In developing each year's Plan, the sum of all projected ICP awards
      will not be allowed to exceed 8% of projected after tax earnings from
      continuing operations.  If the total of all projected ICP awards
      exceeds 8% of the projected after tax earnings from continuing
      operations, then either the number of participants and/or the
      individual target percentages are to be reduced until the total is 8%
      or less.

*     If the Corporation fails to achieve threshold EPS performance, no
      incentive awards will be made under the plan at any level for any
      component for any participant.

Eligibility

Participation in the plan may be extended to Corporate and Dravo Lime
senior managers and other key employees.  Prior to the beginning of each
plan year, eligible participants are recommended by the President and Chief
Executive Officer (CEO) and approved by the Compensation Committee of the
Board of Directors (Committee). 

Individual Target Awards

Target awards are established so as to pay competitive levels of incentive
compensation for achievement of the targeted performance levels. Target
awards will equal a specified percentage of the Midpoint salary of the job
grade for each participant in the plan. Percentages may vary within the job
grade based on accountability of the job as recommended by the CEO and
approved by the Committee each year. 
 
Range of Awards

The target award will be paid at the targeted level of performance on any
component of the plan.

The threshold award, equal to 50 percent of the target award, will be paid
at the threshold level of performance on any component of the plan.  If
performance fails to meet the threshold, no award will be made for that
component.

The optimum award, equal to 150 percent of the target award, will be paid for
performance equal to or above the optimum level of performance on any
component of the Plan.

<PAGE>                             10(iv)-2  

Allocation of Awards Among Components

Awards will be allocated to reflect the organizational level where the
participant has the greatest level of influence on business results.

For all participants awards the greatest weight will be given to corporate
performance.  For participants assigned to a specific operating division, a
portion of their award will be allocated to reflect the performance of their
respective division.

Corporate Component
All participants at the Corporate level, and those participants who are not
assigned to a specific operating division will receive 100% of their award
through the Corporate component. Employees who are assigned to a specific
operating division location will receive 70% of their award through the
Corporate component.  

The performance measure for the Corporate component is Earnings Per
Share (EPS) from continuing operations.  The CEO will recommend to the
Committee for approval threshold, target and optimum levels of EPS
performance for the Plan Year for use in determining awards.

Performance at the threshold level will result in an award of 50% of the
target for this component.   At the target level of performance, the target
award will be made and at the optimum level, the optimum award of 150% of
target will be made.  For intermediate results, awards will be interpolated.  

The Corporate component may be adjusted, with the approval of the
Committee, to reflect the impact of extraordinary events on Corporate EPS.

Divisional Component

Participants employed in the various operating divisions (for example: 
Black River, Maysville and Longview) will receive 30% of their awards
through a Divisional component that is based upon the results attained by
their respective operating division.  

The performance measure for the Divisional component is earnings before
interest and taxes (EBIT).  The CEO will recommend to the Committee for
approval threshold, target and optimum levels of EBIT performance for each
operating division for the plan year for use in determining awards.

The relationship of actual results to awards is determined in the same way
as described above for the Corporate component.  

<PAGE>                             10(iv)-3

The Divisional component may be adjusted, with the approval of the
Committee, to reflect the impact of extraordinary events on an operating
division's EBIT.

Restricted Stock  

For participants in job grade level 24 and above having a target percentage
of 15% or more, the ICP award may be paid in a combination of cash and
restricted stock. The maximum percentage of restricted stock will be
specified for each applicable job grade.  The actual amount of the award
paid in restricted stock will be recommended by the CEO and approved by the
Committee. Restricted stock is a grant and the stock must be held by the
individual for a period of two years after which time the restriction will be
lifted. The individual must be actively employed on the date on which the
restriction is lifted in order to assume full ownership of the stock, unless
their leaving the company is as a result of lay off, change of control
termination, retirement, disability, or death, in which case the lifting of
the restriction will be accelerated.

Partial Year Payments

A new employee, hired into an approved ICP position, will have his target
percentage and component allocation established in accordance with the
Plan.  The employee's award will be calculated at the end of the year along
with other participants, but the award will be prorated based on the number
of months of employment.

Terminations

Employees who terminate from the company prior to December 31 of the plan
year for any reason, with the exception of lay off, change of control
termination, retirement, disability, or death, will forfeit their incentive
compensation for that year.  Employees who leave the company prior to
December 31 due to lay off, change of control termination, retirement,
disability, or in the event of death, will receive a prorated incentive for
those months actually worked.  Employees who leave the company after
December 31 will be paid their award, if any, when other ICP payments are
distributed.  

Promotions

Employees promoted into an ICP position from a non-ICP position, or
employees who are promoted into a position having a higher salary grade,
target percentage and/or different component allocation,  will receive an
award prorated for the number of months spent in the new position.  If an
ICP award has been earned in their previous position, that award will be
prorated by the number of months spent in the previous position.

<PAGE>                             10(iv)-4

Plan Administration

The plan is administered by the Compensation Committee of the Board of
Directors.  The Committee is authorized to interpret the plan, to establish
and amend rules for its administration and to make discretionary
adjustments in awards due to extraordinary events.

Recommendations as to the operation of the plan, eligible participants,
target percentages, component allocations, type (cash and/or restricted
stock) and amount of awards, performance criteria, and extraordinary
adjustments may be made to the Committee by the CEO.

                 remainder of her life, the surviving spouse benefit

<PAGE>                         10(xii)-3
            5.   The Change-In-Control Agreement between Torbert and the
                 Corporation made as of the 1st day of June, 1993 shall
                 continue to apply in accordance with the terms thereof. 
                 For purposes of said Agreement, Torbert's office shall be
                 deemed to be in Mobile, Alabama.

            6.         (a)   Torbert will, upon request of the Chief
                 Executive Officer of Dravo, provide his services on an as
                 needed and as available basis and shall perform such
                 services as the parties may mutually agree.  Such
                 services shall be rendered by Torbert at such time as are
                 mutually convenient to the parties.  While it is
                 anticipated that the services of Torbert hereunder will
                 be performed in the United States, such services may be
                 performed for limited periods of time in those foreign
                 countries that are mutually agreeable to the parties. 
                 Torbert's status will be that of an Executive Consultant
                 and not an independent contractor furnishing services on
                 an established fee basis.  As such, Torbert will be
                 considered an employee of Dravo. 

                       (b)   There shall be no obligation on the part of
                 Torbert, his Executors or Administrators to repay any
                 portion of said compensation irrespective of whether or
                 not Dravo utilizes the services of Torbert hereunder or
                 whether Torbert dies at any time during the term hereof.

            7.   Except as Dravo may otherwise provide, Torbert shall not
                 have, nor shall Torbert represent himself as having, any
                 authority to (i) make proposals or contracts in the name of
                 Dravo or any of its subsidiaries or affiliated companies,
                 (ii) bind Dravo, it subsidiaries or affiliated companies in
                 any matter, (iii) pledge Dravo's credit, or that of its
                 subsidiaries or affiliates, (iv)
<PAGE>                         10(xii)-4<PAGE>
                
                 extend credit in Dravo's name, or in the name of its
                 subsidiaries or affiliates or (v) deal in any manner
                 whatsoever with regard to the services or equipment of
                 Dravo, its subsidiaries or affiliates other than within
                 the scope of the services provided hereunder.

            8.   In addition to the aforesaid compensation, Dravo will
                 reimburse Torbert for all reasonable expenses in
                 accordance with the Dravo standard policy for extended
                 use of personal car, public transportation, food and
                 lodging, as authorized by Dravo and incurred in connection
                 with services furnished under this Agreement.  Torbert
                 shall submit monthly invoices with supporting receipts to
                 Dravo for expenses incurred hereunder during the
                 preceding month and Dravo shall pay the amounts due
                 Torbert on said invoices within thirty (30) days after
                 receipt thereof.

            9.   (a)   Information which is considered by Dravo to be of a
                       confidential or proprietary nature, whether of a
                       business, cost or technical nature, may be disclosed
                       to, or developed by, Torbert in the course of his
                       consulting work.  Torbert acknowledges his
                       obligation to hold such confidential or proprietary
                       information in trust and confidence and not to
                       disclose such information to any person, in
                       accordance with applicable common law.  These
                       restrictions shall not apply to any information
                       which is rightfully in the public domain prior to, or
                       subsequent to, the time it was disclosed, or
                       information which is independently developed by
                       sources other than Dravo.  Upon written request by
                       Dravo, Torbert shall return to Dravo all written or
                       descriptive matter, including, but not limited to,
                       sales scriptions, or other papers and documents
                       which contain such confidential or proprietary
                       information.

                 (b)   Any documents, forms or any other written matter,
                       programs, methods or procedures which may be
                       developed by Dravo and/or Torbert through December
                       31, 1996 within the scope of the services set forth
                       herein shall be and remain the property of Dravo
                       and shall be deemed to be Dravo's confidential or
                       proprietary information for all purposes of this
                       paragraph.

            10.  Dravo shall be entitled to any information beneficial to
                 the purposes of this Agreement and any ideas, inventions
                 and discoveries conceived, made or reduced to practice by
                 Torbert either alone or with others, within the scope of
                 the services of Torbert hereunder, during the consulting
                 term arising out of any investigation or work by Torbert
                 during the consulting term.  If any such ideas, inventions
                 or discoveries can be made the subject of patent
                 applications and patents in the United States or
                 elsewhere, Dravo shall have the right, but only at its
                 expense, to prepare, prosecute, procure and maintain such
                 patent applications and patents, and Torbert will, upon
                 the request of Dravo, execute any and all documents and
                 perform all such other lawful acts that Dravo may deem
                 necessary or desirable to establish and perfect Dravo's
                 ownership with respect to any such ideas, inventions and
                 discoveries and such patent applications and patents.

            11.  In consideration of the mutual promises recited herein,
                 Torbert agrees that Torbert shall not for himself or for
                 any other person, partnership or corporation ("Firm")
                 compete with Dravo by entering into the lime business
                 within the market area served by any such business
                 presently being conducted by Dravo.  Further, Torbert
                 agrees that he shall not participate or consult with any
                 Firm in establishing a new or revised business
                 organization which will compete with Dravo in any of its
                 present businesses or locations 
<PAGE>                         10(xii)-6
                 in the area of lime sales or facilities therefor within
                 such restricted area.  Torbert and Dravo agree that the
                 above provisions shall be effective through December 31,
                 1996.

            12.  As long as this Agreement remains in effect, it is agreed
                 that Dravo may freely use Torbert's name, refer to his
                 professional qualifications and experience, include his
                 name in listings of its consultants and describe Torbert
                 as a consultant to it within the scope of services
                 described herein, and that Torbert may likewise refer to
                 himself as an Executive Consultant to Dravo within the
                 scope of services described herein.

            13.  Either party hereto, in the event of default by the other
                 party of any of the terms and conditions herein set forth
                 to be performed or undertaken by such party, may,
                 provided such defaulting party has not remedied such
                 default within thirty days after notice thereof given by
                 the non-defaulting party, in addition to any remedies
                 available to it in law or in equity, declare this Agreement
                 to be ended and of no further force or effect.

            14.  Dravo relies upon the personal skill, experience and
                 abilities of Torbert in performing the services provided
                 in this Agreement.  Therefore, Torbert shall not assign
                 this Agreement in whole or in part.

            15.  As a material inducement to Dravo to enter into this
                 Agreement, Torbert hereby irrevocably and
                 unconditionally releases, acquits and forever discharges
                 Dravo and each of its owners, stockholders, predecessors,
                 successors, assigns, agents, directors, members,
                 officers, employees, representatives, attorneys,
                 divisions, groups, subsidiaries and affiliates (and
                 agents, directors, officers, employees, representatives
                 and attorneys of 
<PAGE>                         10(xii)-7
                 Dravo and such divisions, groups, subsidiaries and
                 affiliates), and all persons acting by, through, under or
                 in concert with any of them (collectively, "Releasees"), or
                 any of them, from any and all complaints, claims,
                 liabilities, causes of action, and expenses (including
                 attorney fees, costs actually incurred and liquidated
                 damages), known or unknown, which he may now, at any time
                 heretofore or hereafter, have or claim to have against
                 each or any of the Releasees arising from any alleged
                 violation through the date of this Agreement by Dravo or
                 any affiliate of the Age Discrimination in Employment Act,
                 as amended.  Similarly, Dravo releases and waives any and
                 all claims or causes of action it may have against Torbert
                 which exist up through the date of this Agreement. 
                 Nothing in this Agreement shall be deemed to waive any of
                 Torbert's rights under ERISA to participate in Dravo's
                 benefit plans for which he is otherwise eligible to
                 participate or to receive benefits from those plans which
                 he is eligible to receive in accordance with the plan
                 provisions.

            16.  Torbert represents and acknowledges that in executing
                 this Agreement he does not rely, and has not relied, upon
                 any representation or statement made by any of the
                 Releasees' agents, representatives or attorneys with
                 regard to the subject matter, basis or effect of this
                 Agreement or otherwise.

            17.  Torbert acknowledges that he has been advised in writing
                 to discuss or review the contents of this Agreement with
                 a lawyer of his choosing and that he has been given up to
                 twenty-one (21) days in which to consider the terms of
                 this Agreement.  Torbert acknowledges that if he signs
                 this Agreement prior to the expiration of the full
                 twenty-one day period, he has done so voluntarily. 
                 Torbert further acknowledges that he has consulted 
<PAGE>                         10(xii)-8
                 with his attorney prior to entering into this Agreement,
                 and that he has entered into this Agreement voluntarily
                 and of his own free will.

            18.  Torbert shall have seven (7) days following the execution
                 of this Agreement to revoke it.  Should Torbert wish to
                 revoke this Agreement, he must notify   John R. Major, Vice
                 President - Administration, Dravo Corporation, One Oliver

                 such notice must be received within seven (7) days from
                 his signature.

            19.  This Agreement shall be binding upon Torbert and upon his
                 heirs, administrators, representatives, executors,
                 successors and assigns, and shall inure to the benefit of
                 Releasees and each of them, and to their heirs,
                 administrators, representatives, executors, successors
                 and assigns.

            20.  Should any provisions of this Agreement be declared or be
                 determined by any court to be illegal or invalid, the
                 validity to the remaining parts, terms or provisions shall
                 not be affected thereby, and said illegal or invalid part,
                 term, or provision shall be deemed not to be a part of this
                 Agreement.

            21.  Except as otherwise provided herein, this Agreement sets
                 forth the entire agreement between the parties hereto

FINANCIAL REVIEW

OVERVIEW

Two milestone events during 1994 will determine to a great extent Dravo
Corporation's future.  The first was the completion late in the year of
negotiations to sell substantially all the assets of Dravo Basic Materials,
the company's construction aggregates business.  The aggregates operations
comprised more than half of the company's assets and generated over half of
its revenues.  During the past few years, however, the return on investment
from this business had fallen below acceptable levels.  The opportunity to
sell the business in excess of book value allowed the company to exit a
business currently earning marginal returns while significantly strengthening
the balance sheet.  The result is a highly focused, conservatively financed
lime company.

The second 1994 milestone directly involved the lime business: a 700,000-ton-
per-year expansion of the company's Black River lime production facility
neared completion.  Production from this expansion will be used to meet the
450,000-ton-per-year scrubber lime requirement of American Electric Power's
Gavin station, and also to supply the Henderson Municipal Power and Light
Station operated by Big Rivers Electric Cooperative.  The company will provide
the Gavin station lime tonnage under a 15-year contract.  The extension of
three long-term supply commitments totaling almost 700,000 tons annually, and
the increase in lime utilization expected at existing customer locations as
utilities boost their levels of sulfur-dioxide removal, underpin revenues from
the utility segment of Dravo's lime operations into the next decade.

The Dravo Basic Materials sales transaction was not completed until year-end;
therefore, the consolidated financial results for 1994 reflect both the lime
and construction aggregates operations for the entire year.  Continuing
operations pre-tax earnings of $5.5 million were notably lower than the $10.5
million posted in 1993, primarily because of price reductions given to secure
renewal of long-term lime supply contracts, unusually high weather-related
costs, and startup costs associated with the Black River expansion.  Earnings
from continuing operations after tax were $4.9 million, or $.16 per share.

Dravo reported a net loss for 1994 of $10.6 million, or $.88 per share.  A
charge for discontinued operations of $6.5 million was recorded in 1994 for
expected legal fees for two ongoing lawsuits and to provide for settlement of
a lawsuit brought in Venezuela for contract services provided in the mid-
1970s.  Also, an extraordinary charge of $7.6 million, $.51 per share, was
recorded to reflect the write-off of fees associated with debt instruments
that were prepaid or substantially altered as a result of the Dravo Basic
Materials asset sale.  A one-time charge of $1.4 million, $.09 per share,
reflects the cumulative accounting effect of the adoption of Statement of
Financial Accounting Standards No. 112, "Employers Accounting for
Postemployment Benefits."

In 1993, earnings from continuing operations were $35.1 million, or $2.20 per
share.  Included in the earnings results was a $24.9 million deferred tax
benefit.  Loss on discontinued operations was $35.3 million, or $2.38 per
share.

In 1992, earnings from continuing operations were $10.3 million, or $.52 per
share.  Under rules in effect in 1992 governing accounting for income taxes,
an extraordinary credit of $1.6 million, or $.11 per share, resulted from the
use of loss carryforwards to offset current tax expense.

RESULTS OF OPERATIONS

CONTINUING OPERATIONS

Revenue:  Revenue of $278.1 million during 1994 was up slightly over 1993's
level.  Construction aggregates revenue was higher due to continued strong
demand in the Cincinnati and West Virginia areas and a much improved market in
the Southeast and Gulf Coast areas.  Lime revenue of $125.7 million was down
due to price concessions granted in return for multi-year extensions of long-
term lime supply contracts and weather-related problems in the first quarter. 
The impact of these items was partially mitigated, however, by very strong
demand for non-utility lime.  Demand was especially strong for metallurgical
lime used in making steel and aluminum.

Revenue in 1993 of $277.6 million was up $4.6 million over 1992.  The increase
was attributable to high demand for construction aggregates in the
metropolitan Cincinnati area and West Virginia.  Competition along the
Mississippi River and Gulf Coast was very intense and the company was unable
to increase revenues in those areas.  Lime revenue was up due to strong non-
utility demand and increased utility shipments.

Costs and Expenses:  Gross profit of $44.0 million was down $5.3 million from
last year.  Dravo Lime's gross profit of $30.4 million was down $4.6 million
while Dravo Basic Materials' gross profit of $13.2 million was down $644,000
from a year ago.  Lime and aggregates operations located in the Ohio River
Valley were negatively affected by a severe winter that caused operating
difficulties during the first quarter.  Price concessions on long-term lime
supply contracts impacted gross profit, as did an unscheduled seven-week
outage at one of the company's electric utility customer's generating
stations.  Production costs at the Black River operation were higher as
personnel were added in preparation for expanded underground mining and
startup of the two new lime kilns.  Also, the write-off of equipment being 

<PAGE>                              13-18

replaced as part of the plant expansion and modernization project affected
profit margins.  The expansion and upgrades currently being completed at Black
River are expected to reduce production costs significantly.

Gross profit was $2.4 million lower in 1993 than 1992.  An unusual number of
significant operating problems at Black River increased production costs. 
Operating problems occurred at the Longview facility also, although not to the
same extent as Black River, and the company had to occasionally purchase lime
from outside sources to fill orders.

Selling expense of $7.1 million was lower than both 1993 and 1992 levels of
$7.6 million and $7.3 million, respectively.  Selling expense fluctuates
primarily due to amounts of research and development expense that can be
billed to third parties.  These research activities involve a variety of lime-
related technologies, with particular emphasis on air pollution control. 
Depending on the project, reimbursement may be made by governmental agencies,
public utilities or private groups for all or a portion of project costs.

General and administrative expenses were reduced by more than six percent from
1993 and ten percent from 1992.  The reduction reflects lower staffing levels,
employee and retiree medical expenses, and travel expenses, as well as lower
charges related to the amortization of a non-cancelable lease obligation on a
downtown Pittsburgh office building.  The decrease from 1992 to 1993 was due
primarily to lower amortization charges on the non-cancelable lease and lower
medical expenses.

Equity in earnings of joint ventures includes the company's share in three 50-
percent owned joint ventures: a shell dredging operation located off the
Louisiana coast, a contract phosphate rock mining operation in Idaho and a
small contract coke operation in Wyoming.  Results for the shell dredging
operation were significantly improved over last year due to a major highway
project and a contract with a state agency to place shell in water bottoms to
improve oyster habitat.  The phosphate mining operation, whose profitability
varies depending on mining conditions and customer requirements, had strong
demand and improved results over 1993.  The shell dredging joint venture was
sold as part of the Dravo Basic Materials asset sale.

Other income reports the gain on the sale of property, plant and equipment. 
The $1.1 million gain in 1994 includes the sale of the company's airplane,
$324,000, and $487,000 from the sale, after accrued expenses, of Dravo Basic
Materials' assets.  See Note 3, Dispositions, in the Notes to Consolidated
Financial Statements for a further discussion of the Dravo Basic Materials
sale transaction.  In 1993, a gain was recognized on the sale of property in
Baton Rouge, Louisiana and excess floating equipment, mainly barges.  Other
income in 1992 of $1.7 million resulted primarily from the sale of assets
related to the asphalt and Calcilox businesses.  A gain was also recorded when
the lessee of 34 hopper barges and covers exercised an option to purchase the
equipment.

The decline in interest income over the last two years reflects a lower level
of funds available for investment and lower interest rates.

Interest expense of $12.4 million was $3.2 million higher than 1993.  The
higher expense was due to higher interest rates on a prime rate-based line of
credit and fees paid to a prospective lender on the Black River financing
package whose participation was terminated by the company.  Interest expense
was 13 percent lower in 1993 than 1992.  The decrease was due to lower average
debt outstanding and the positive impact of an interest rate swap agreement.

Income tax expense of $597,000 includes an accrual of $300,000 for federal
alternative minimum tax from the sale of Dravo Basic Materials' assets.  In
1993, a benefit for income taxes of $24.9 million was recorded under the
provisions of Statement of Financial Accounting Standards No. 109 (SFAS 109),
"Accounting for Income Taxes."  Management believes that, due to the large
proportion of revenue generated by long-term supply contracts, income can be
reasonably projected for purposes of determining whether the realization of
the asset resulting from the utilization of NOLs in future years is more
likely than not.  The amount of the net deferred tax asset was not adjusted in
1994 due to remaining uncertainties associated with discontinued operations.

In conjunction with the sale of Dravo Basic Materials' assets, existing loan
agreements were substantially altered, including a $35 million reduction in
the amount available under a revolving credit facility.  Also, while
negotiating a $50 million financing agreement with Prudential Power Funding
for the Black River expansion, the company purchased a call option that
enabled it to prepay on May 17, 1995, without penalty, amounts outstanding
under the financing agreement.  At December 31, 1994, $19.9 million was
borrowed under the agreement.  Cash received from the Dravo Basic Materials
asset sale equalling the outstanding principal on the Prudential Power Funding
facility, interest through May 16, 1995 and an exit fee was placed in escrow. 
The company agreed that any additional drawings on the facility would also be
escrowed.  No additional drawings were made and, with Prudential Power
Funding's consent, the entire amount borrowed was prepaid on February 10,
1995.  The fees associated with these agreements were written off as
extraordinary items.

<PAGE>                              13-19

Effects of inflation:  Inflation rates have been low over the past three years
and as a result have not had a significant impact on the company's operations. 
In addition, Dravo Lime's long-term lime supply contracts provide for price
increases for specific production expenses, such as labor, fuel and
electricity.

DISCONTINUED OPERATIONS

The provision for discontinued operations was increased $6.6 million in 1994. 
The charge was taken to cover a $4.5 million settlement involving an alleged
breach of contract by the company for work performed between 1973 and 1978 in
Venezuela.  Because of the uncertainty surrounding this matter, no amount was
provided previously.  Opposing counsel had alleged damages in excess of $35
million.  The balance of the provision is, for the most part, estimated legal
fees for two ongoing lawsuits: Continental Energy Associates and the company's
assertion that it is entitled to a defense and indemnity under its contracts
of insurance for environmental clean-up costs in Hastings, Nebraska.  See Note
8, Contingent Liabilities, in the Notes to Consolidated Financial Statements
for a further discussion of these matters.

In 1993, a $35.3 million charge was recorded.  The provision was primarily to
cover a settlement agreement with the City of Long Beach, Calif., which
included the company giving up its claim to unpaid receivables and interest
totalling $18 million.  The provision also recognized an increase in the
estimated environmental clean-up costs at the Hastings superfund site, write-
off of a note receivable due to an unfavorable court ruling and additional
legal fees.

FINANCIAL POSITION AND LIQUIDITY

The company completed negotiations on December 30, 1994 for the sale of
substantially all of the assets and certain liabilities of Dravo Basic
Materials to Martin Marietta Materials, Inc. (Martin Marietta) effective
January 3, 1995.  The balance sheet at December 31, 1994 reflects the effect
of the sale transaction, in that the assets and liabilities sold have been
removed and a $120.5 million receivable from Martin Marietta recorded.  On
January 3, 1995, cash was received for the assets.

Also on January 3, the company prepaid $65.6 million of debt, including the
revolving line of credit balance of $55.8 million.  On February 10, 1995 the
Prudential Power Funding loan balance of $19.9 million was prepaid. 
Accordingly, these amounts are presented as current liabilities on the
December 31, 1994 balance sheet.  The company's total debt outstanding after
prepaying these loans was $42.4 million and it had available $32.5 million
under a revolving credit/letter of credit facility.

All known outstanding discontinued operations items have been classified as
current or long-term based on the estimated timing of future cash receipts and
disbursements.  Despite the size of the discontinued operations liabilities,
they do not pose a threat to liquidity because cash payments needed to satisfy
them will be spread over several years.

The company has on hand and access to sufficient funds to meet its anticipated
operating and capital needs.  To minimize interest charges, cash balances are
kept low through a banking arrangement that uses excess cash held in the
company's accounts to reduce the amount of overnight borrowing on a revolving
credit agreement

Cash received from the Dravo Basic Materials transaction, after payment of
debt and expenses, is being invested in short-term interest bearing
instruments.

In January, 1995 the Board of Directors approved a program whereby the company
is authorized to purchase up to 250,000 shares of its common stock on the open
market.  The repurchased shares will be held in the treasury and will be used
for general corporate purposes.

A $40 million revolving credit/letter of credit facility is provided by a
consortium of lenders that includes First Alabama Bank; PNC Bank, N.A. and
Bank of America Illinois (formerly Continental Bank, N.A.).  Interest on the
revolver is equal to First Alabama Bank's base lending rate plus 1.25 percent. 
The credit facility expires April 30, 1996 but the company expects it to be
extended.

Obligations under the company's revolving credit facility and senior term
notes are secured by a pledge of the stock of Dravo Lime Company and Dravo
Basic Materials Company along with their accounts receivable and finished
goods inventories.  Additionally, certain contract rights, patents and
mortgages on the company's Maysville, Black River and Longview plants have
been pledged as collateral.  The agreements contain uniform restrictive
covenants that require the company on a consolidated basis, and Dravo Lime and
Dravo Basic Materials on a combined basis, to maintain minimum working capital
levels; restrict incurrence of debt, liens and lease obligations; restrict the
sale of significant assets; and as to Dravo Lime and Dravo Basic Materials,
limit payment of dividends or making of loans to the company.  At December 31,
1994, approximately  $155 million of Dravo Lime and Dravo Basic Materials net
assets were restricted as to payment of dividends or loans to the company. 
These restrictions are not expected to have an adverse impact on the company's
ability to meet its cash obligations.

DIVIDENDS

The company may not declare common stock dividends until cumulative earnings
from continuing operations after September 30, 1991 exceed $40 million,
excluding gains from the sale of capital assets and the income

<PAGE>                              13-20

impact of recording a net deferred tax asset, or cumulative losses from
discontinued operations after September 30, 1991, whichever is higher, and
then only to the extent of 50 percent of such earnings.  At December 31, 1994,
cumulative losses from discontinued operations of $52.3 million exceeded
cumulative earnings from continuing operations, both since September 30, 1991,
by $25.7 million.  Dividends on the $3.0875 cumulative, convertible,
exchangeable, Series D Preference Stock were declared quarterly throughout
1994, 1993 and 1992.  Quarterly dividends were also declared on the $2.475
cumulative convertible Series B Preference Stock in each of the last three
years.  All declared preference dividends have been paid on a timely basis.

COMMON STOCK MARKET PRICE

The principal market on which Dravo's common stock is traded is the New York
Stock Exchange under the symbol, DRV.  The high and low common stock sales
prices for each quarterly period in 1994 and 1993 as reported for New York
Stock Exchange composite transactions were:

OUTLOOK

Continuing operations:  Dravo Corporation is now a company focused on one
business, lime.  Five years ago Congress passed amendments to clean air
standards mandating reduced emissions from coal-fired power plants.  The
effective date for the first phase of these mandated emission reductions was
January 1, 1995.   In January, 1995 Dravo shipped lime to American Electric
Power's Gavin station under a 15-year supply contact.  This marked the
beginning of a major expansion in the company's utility lime operations
directly attributable to the new federal clean air standards.  Demand from the
steel, paper and water purification markets has exceeded the company's non-
utility lime production capacity.  Additional expansions to supply this
increase in demand are anticipated.  In total, Dravo now has nearly 70 percent
of its total production capacity committed under long-term utility and
merchant contracts.

The company's research and development organization is recognized as a leading
source of technical services to lime users and a major developer of lime-
related environmental technologies.  The company leverages this competitive
advantage in seeking additional lime and lime-related businesses and also is
committed to commercializing and marketing its patented technologies.

Administrative costs were significantly reduced as part of the corporate
reorganization that followed the sale of Dravo Basic Materials' assets.  A
much smaller corporate staff is being consolidated at Dravo's Pittsburgh
headquarters location to better support and complement Dravo Lime's
activities.  Ongoing reductions in overhead expenses are a management
priority.

Discontinued operations:  The company formerly operated a metal fabrication
facility in Hastings, Nebraska.  The federal Environmental Protection Agency
(EPA) has notified the company it believes the company is a potentially
responsible party (PRP) for the clean-up of soil and groundwater contamination
at four subsites in the Hastings area.  The company held talks with the EPA in
1992 as to the scope of clean-up required and to determine if the EPA would be
willing to accept an amount, to be paid by the company, other PRPs and the
company's insurance carriers, over time, that would discharge the company from
any further clean-up at the Colorado Avenue subsite.  The company discontinued
the discussions with the EPA when its insurance carriers refused coverage
responsibility.  The company has since brought legal action against its
insurance carriers whom it believes had coverage responsibility for the time
the company owned the Hastings facility.  Two insurance carriers have
approached the company concerning a settlement.  The one carrier, whom the
company considered having the least exposure, settled in 1994 for $500,000. 
The company intends to pursue a settlement of this matter which will involve a
group of named PRPs and insurance carriers.  See Note 2, Discontinued
Operations, in the Notes to Consolidated Financial Statements for further
discussion of the company's estimate of total clean-up costs and its share of
those costs.

A mediation session was held in early March, 1995 between the company and
Continental Energy Associates regarding disputes arising from the construction
of a coal gasification facility in Hazleton, Pennsylvania.  Although the
session did not resolve this matter, the company is hopeful that the dialogue
will continue and ultimately lead to a fair settlement acceptable to the
company.

See Note 8, Contingent Liabilities, in the Notes to Consolidated Financial
Statements for a further discussion of these discontinued operations matters.

Management believes the provision for losses on discontinued operations is
adequate at this time.  However, in establishing the provision and monitoring
it, management has estimated the cost of exiting discontinued businesses and
pursuing the company's rights through litigation.  A ruling by the courts or a
settlement of the disputes that is adverse to Dravo's position, or other
unforeseen developments, could require a future additional provision for
discontinued operations.

                      DRAVO CORPORATION AND SUBSIDIARIES

                  Notes to Consolidated Financial Statements
                                                                               
     
Note 1: Summary of Significant Accounting Policies
     
Description of Business:  The consolidated financial statements include the
accounts of Dravo Corporation and its majority-owned subsidiaries (the
company).  The principal subsidiaries are Dravo Lime Company, one of the
nation's largest lime producers, and Dravo Basic Materials Company, Inc.
(DBM).  The company completed a transaction on December 30, 1994 in which it
sold substantially all the assets and certain liabilities of DBM.  The assets
and liabilities sold have been removed from the company's December 31, 1994
balance sheet.  The December 31, 1994 statement of operations includes the
results of DBM for the entire year.

Principles of Consolidation:  Significant intercompany balances and
transactions have been eliminated in the consolidation process.

Cash and Cash Equivalents: For purposes of reporting cash flows, the company
considers all highly liquid debt instruments purchased with a maturity of
three months or less to be cash equivalents.

Inventories:  Inventories are valued at average production cost or market,
whichever is lower.  The cost of products produced includes raw materials,
direct labor and operating overhead.

Property, Plant, Equipment and Depreciation:  Property, plant and equipment
are stated at cost.  The cost of buildings, equipment and machinery is
depreciated over estimated useful lives on a straight-line basis.  For income
tax purposes, depreciation is calculated principally on an accelerated basis. 
Expenditures for maintenance and repairs which do not materially extend the
lives of assets are expensed currently.  The asset cost and accumulated
depreciation are removed from the accounts for assets sold or retired, and any
resulting gain or loss is included in other income and expense.

Intangible Assets:  Intangible assets include agreements, goodwill, and
unrecognized prior service cost on the company's pension plans.  Amortization
is on a straight line basis, generally five to ten years, over estimated
useful lives, or in the case of unrecognized prior service costs, the average
future service period. 

Income Taxes:  Effective January 1, 1993, the company adopted the provisions
of Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes."  The statement requires that deferred income taxes reflect the tax
consequences on future years of differences between the tax bases of assets
and liabilities and their financial reporting amounts.  Prior to 1993,
provisions were made for deferred income taxes where differences existed
between the time transactions affected taxable income and the time those
transactions entered into the determination of income for financial statement
purposes.

Earnings Per Share:  Primary earnings per share are based on net earnings less
preference dividends declared in the year, divided by the weighted average sum
of common shares outstanding during the year and common share equivalents. 
Shares exercisable as employee stock options and stock appreciation rights are
considered common share equivalents except when their inclusion would be anti-
dilutive.  Primary common share equivalents are calculated based on the
average common stock price for the year.  Fully diluted earnings per share are
based on net earnings, divided by the sum of the weighted average number of
common shares outstanding during the year, weighted average number of shares
resulting from the assumed conversion of issued preference shares to common
shares and common share equivalents.  Fully diluted common share equivalents
are calculated based on the higher of the average or ending common stock price
for the year.  Fully diluted earnings per share are anti-dilutive in 1994,
1993 and 1992 and are not presented.

Note 2:  Discontinued Operations

In December, 1987, Dravo's Board of Directors approved a major restructuring
program which concentrated the company's future direction exclusively on
opportunities involving its natural resources business.  An additional charge
of $6.5 million was taken in 1994 for discontinued operations.

The company filed an action in 1981 to collect on a promissory note issued by 
Meladuras Portuguesa, C. A. (Melaport) and its principal, Alberto Caldera
(Caldera).  In 1985, Melaport and Caldera filed a counterclaim for damages
alleging the company breached a contract between Melaport and the company
relating to engineering and procurement services rendered between 1973 and
1978 for a sugar cane processing facility.  A local Venezuelan court ruled
partially in favor of Melaport's counterclaim.  The ruling was upheld by a
Venezuelan appeals court on September 25, 1992 and by the Venezuelan Supreme
Court on July 8, 1993.  The court ruling did not specify damages to be paid
but rather  identified three categories of damages to which Caldera and
Melaport would be entitled.  The amount of damages was to have been
established by an appraisal process conducted by the trial court.  Opposing
counsel asserted that the damages would be in excess of $35 million.  The 1994
discontinued operations provision includes $4.5 million for the settlement
amount agreed to by the parties to conclude all disputes related to the
Venezuelan matter.

<PAGE>                              13-28

Also, an additional amount was provided for estimated legal fees anticipated
to pursue various lawsuits and claims, the most significant of which are the
Hastings insurance litigation and Continental Energy Associates (CEA) matters
discussed in Note 8, Contingent Liabilities.

No loss provision has been made for the CEA dispute because it is not possible
to determine the outcome of this matter or to estimate with any degree of
probability the range of potential costs which may be involved.  Claims
against the company, which management believes are grossly overstated, exceed
$10 million.

A $35.3 million provision for discontinued operations expenses was recorded in
1993.  The provision covered the write-off of receivables and accrual of a
settlement relating to a resource recover facility built in Long Beach,
Calif.; updated estimates of the potential costs to clean up soil and
groundwater contamination at a former operation located in Hastings, Nebraska;
write-down of a receivable from a Portland, Maine utility to reflect a jury
award; and estimated legal fees.


The company received cash proceeds of $1.6 million in 1994, $2.0 million in
1993 and $2.6 million in 1992 from the repayment of notes received from the
previous sales of discontinued businesses.

The remaining discontinued operations' assets and liabilities for the
respective years ended December 31 relate to non-cancelable leases,
environmental, insurance, legal and other matters associated with exiting the
engineering and construction business and are presented below:

Note 3:  Dispositions

The company completed a transaction on December 30, 1994 in which it sold to
Martin Marietta Materials, Inc. (Martin Marietta), effective January 3, 1995,
substantially all the assets of its construction aggregates business.  Assets
sold included the assets, properties and leases of Dravo Basic Materials
Company, Inc. (DBM), a wholly-owned subsidiary of the company, and Atchafalaya
Mining Company, Inc. (AMC), a wholly-owned subsidiary of DBM, used in the
production, marketing, distribution and sale of various aggregate products. 
Also sold was the capital stock of Dravo Bahama Rock Limited (DBR), a wholly-
owned foreign subsidiary of DBM.

The significant terms of the transaction called for Martin Marietta to
purchase substantially all of DBM's and AMC's assets at their December 31,
1994 book value plus a premium of $2.0 million.  Assets excluded from the sale
included cash in banks; the capital stock of two subsidiary companies, Dravo
Natural Resources Company and Tideland Industries, Inc.; amounts due from
affiliated companies; notes receivable and certain properties located near
Cincinnati, Ohio and Lake Charles, Louisiana.  The company is required to buy
back accounts receivable that are unpaid at May 3, 1995.

Martin Marietta also paid the company $8.0 million in consideration of (i) a
non-competition and non-disclosure agreement and (ii) distributorship
agreements for crushed limestone aggregates produced at Dravo Lime's
Maysville, Black River and Longview facilities.

The company, DBM and AMC retained substantially all obligations and
liabilities which arose from or in connection with operations prior to the
sales transaction.  The sales price was reduced for liabilities assumed by
Martin Marietta which included accrued vacations and wages for transferred
employees, liabilities of DBR and land reclamation obligations.

Actual and estimated expenses related to the sale totaled $9.5 million and
included transaction costs, benefit plan curtailment expenses, environmental
clean-up costs, severance pay and various wind-down costs.  A net $487,000
pre-tax gain on the transaction was recorded in other income.

The assets and liabilities sold to Martin Marietta have been removed from the
company's December 31, 1994 balance sheet and a corresponding receivable from
the sale of DBM of $120.5 million has been recorded.  The December 31, 1994
statement of operations includes the results of DBM for the entire year.

Pro forma data is provided below for comparative purposes only and does not
purport to be indicative of the

<PAGE>                              13-29

results which actually would have been obtained if the disposition had been
effected on the pro forma dates, or of the results which may be obtained in
the future.

The following pro forma statement of operations presents the results of
operations assuming the disposition had been completed as of the beginning of
1994.  Adjustments have been made to exclude the results of DBM, to decrease
interest expense for loans prepaid in early 1995 from the sale proceeds, and
to record interest income at overnight investment rates for cash received in
excess of liabilities paid.

</TABLE> 
The following is a description of the terms and conditions of the company's
major debt instruments:

The $55.8 million note payable was borrowed under a $75.0 million revolving
credit/letter of credit facility with First Alabama Bank; PNC Bank, N.A.; Bank
of America Illinois (formerly Continental Bank, N.A.) and The Prudential
Insurance Company of America.  Interest on the revolver equals First Alabama
Bank's base lending rate plus 1.25 percent.  The entire amount borrowed under
the revolving line of credit was repaid on January 3, 1995 from the Dravo
Basic Materials asset sale proceeds.  On the same date, the total amount
available for revolving credit/letter of credit requirements under the
facility was reduced to $40.0 million.  The interest rate remained unchanged. 
Participating institutions in the revised revolving credit/letter of credit
facility are First Alabama Bank;

<PAGE>                              13-30

PNC Bank, N.A. and Bank of America Illinois.  The facility expires April 30,
1996 but the company expects it to be extended.

The variable rate note and 9.95 percent promissory notes were prepaid on
January 3, 1995.

The 10.13 percent construction notes provided for borrowing up to $50 million
for the Black River plant expansion.  An amount sufficient to retire these
notes was escrowed from a portion of the Dravo Basic Materials sale proceeds. 
The notes were prepaid on February 10, 1995.

The 11.21 percent term notes require quarterly interest payments and annual
principal repayments in the amount of $6.0 million beginning January, 1996.

Obligations under the revised revolving credit/letter of credit facility and
the 11.21 percent term notes are secured by a pledge of the stock of Dravo
Lime Company and Dravo Basic Materials Company along with their accounts
receivable and finished goods inventories.  Additionally, certain contract
rights, patents and mortgages on the company's Maysville, Black River and
Longview plants have been pledged as collateral.  The agreements contain
uniform restrictive covenants that require the company on a consolidated
basis, and Dravo Lime and Dravo Basic Materials on a combined basis, to
maintain minimum working capital levels; restrict incurrence of debt, liens
and lease obligations; restrict the sale of significant assets and as to Dravo
Lime and Dravo Basic Materials, limit payment of dividends or making of loans
to the company.  The company may not declare common stock dividends until
cumulative earnings from continuing operations after September 30, 1991 exceed
$40.0 million, excluding gains from the sale of capital assets and the income
impact of recording a net deferred tax asset, or cumulative losses from
discontinued operations after September 30, 1991, whichever is higher, and
then only to the extent of 50 percent of such earnings.  At December 31, 1994,
cumulative losses from discontinued operations of $52.3 million exceeded
cumulative earnings from continuing operations, both since September 30, 1991,
by $25.7 million.

At December 31, 1994, approximately $155 million of Dravo Lime and Dravo Basic
Materials' net assets were restricted as to payment of dividends or loans to
the company.  Assets pledged under certain notes and leases had a book value
of $228.2 million at December 31, 1994.

In February, 1993, the company entered into an interest rate swap agreement
with Continental Bank, N.A. on the $41.8 million fixed rate long-term notes
payable.  The transaction was accounted for as a hedge of those notes.  On
December 30, 1994, the company paid $1.4 million to unwind the swap agreement.

Amounts payable on long-term debt due in 1995 and thereafter are: 1995, $29.3
million; 1996, $6.2 million; 1997, $6.2 million; 1998, $6.1 million; 1999,
$6.0 million; and after 1999, $17.9 million.

Note 6: Redeemable Preference Stock

The company has outstanding 200,000 shares of cumulative, convertible,
exchangeable, Series D Preference Stock.  Cumulative dividends of $3.0875 per
share are payable quarterly.  Each share of preference stock may be converted,
at the option of the holder, into 8.0 shares of common stock.  The stock is
also exchangeable, at the option of the company, for 12.35 percent Senior
Subordinated Convertible notes due September 21, 2001.  The 12.35 percent
senior subordinated notes would contain the same conversion rights,
restrictions and other terms as the preference stock.

The company may redeem the stock, in whole or in part, after January 21, 1996
for $100 per share plus accrued dividends, provided that the market price of
common stock as of the date of the decision to redeem the shares, as defined
in the Certificate of Designations, Preferences and Rights for the Series D
Preference Stock, shall be at least equal to 175 percent of the conversion
price for the preference stock.  Mandatory annual redemption of the lesser of
50,000 shares or the number of shares then outstanding begins September 21,
1998 at $100 per share plus accrued dividends.  In the event of liquidation of
the company, the holders of outstanding Series D Preference Stock shall be
entitled to receive a distribution of $100 per share plus accrued dividends.

The company had outstanding 28,386 and 32,386 shares of cumulative,
convertible Series B Preference Stock on December 31, 1994 and 1993,
respectively.  Cumulative annual dividends of $2.475 per share are payable
quarterly.  Each share of Series B Preference Stock may be converted at the
option of the holder to 3.216 shares of common stock.  In the event of the
company's liquidation, the holders of the Series B Preference Stock are
entitled to $55 per share plus all accumulated and unpaid dividends.

At December 31, 1994 and 1993, the company had outstanding letters of credit
totaling $7.5 million and $10.0 million, respectively.

Note 8: Contingent Liabilities

The company has been notified by the federal Environmental Protection Agency
(EPA) that the EPA believes the company is a potentially responsible party
(PRP) for the clean-up of soil and groundwater contamination at four subsites
in Hastings, Nebraska.  The Hastings site is one of the EPA's priority sites
for taking remedial action under the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA).  

At one of these subsites, a municipal landfill, the company believes it could
not have disposed of hazardous wastes at the particular subsite because the
landfill was closed prior to the time the company and its predecessor
initiated the operation which generated the type of hazardous substances found
at this subsite.  Other PRPs, including the local municipality, have agreed to
perform the remedial investigation and to design soil and groundwater remedies
at this subsite.

The company has also been notified by EPA that EPA considers it a PRP at
another municipal landfill in Hastings.  At least three other parties
(including the City of Hastings) are considered by EPA to be PRPs at this
second subsite.  At this subsite, the company has concluded that the City of
Hastings is responsible for a proper closure of the landfill and the
remediation of any release of hazardous substances.  In January, 1994, EPA
invited the company and the other PRPs to make an offer to conduct a remedial
investigation and feasibility study (RI/FS) of this subsite and stated that
the EPA was in the process of preparing a work plan for the RI/FS.  None of
the PRPs has volunteered to undertake the RI/FS.

With respect to the third subsite, the company and two other PRPs have been
served with administrative orders directing them to undertake soil remediation
and interim groundwater remediation at that subsite.  The company is currently
complying with these orders while reserving its right to seek reimbursement
from the United States for its costs if it is determined it is not liable for
response costs or if it is required to incur costs because of arbitrary,
capricious or unreasonable requirements imposed by the EPA.  

The EPA has taken no legal action with respect to its demand that the company
and the other PRPs pay its past response costs.  A total of five parties have
been named by the EPA as PRPs at this subsite, but two of them have been
granted de minimis status.  The company believes other persons should also be
named as PRPs.

The fourth subsite is a former naval ammunition depot which was subsequently
converted to an industrial park.  The company and its predecessor owned and
operated an HVAC facility in this industrial park.  To date the company's
investigation indicates that it did not cause the release of hazardous
substances in this subsite during the time it owned and operated the
facility.  The United States has undertaken to conduct the remediation of
this subsite.

In addition to subsite clean-up, the EPA is seeking a clean-up of area-wide
contamination associated with all of the subsites in and around Hastings,
Nebraska.  The company, along with other Hastings PRPs, has recommended that
the EPA adopt institutional controls as the area-wide remedy in Hastings. 
EPA has indicated some interest in this proposal but has decided to first
conduct an area-wide remedial investigation before choosing a remedy. 

On August 10, 1992 the company filed suit in the Alabama District Court
against its primary liability insurance carriers and one of its
predecessor's insurers, seeking a declaratory judgment that the company is
entitled to a defense and indemnity under its contracts of insurance
(including certain excess policies provided by one of the primary carriers)
with regard to the third Hastings subsite.  The company recently settled the
claim against its predecessor's insurer, but the case against the company's
insurers is still in litigation.  An award of punitive damages is also being
sought against the company's insurers for their bad faith in failing to
investigate the company's claim and/or denying the company's claim.  The
company has notified its primary and excess general liability carrier, as
well as the excess carrier of its predecessor, of the receipt of its notice
of potential liability at the first, second and fourth subsites.

Estimated total clean-up costs, including capital outlays and future
maintenance costs for soil and groundwater remediation of approximately $18
million, are based on independent engineering studies.  Included in the
discontinued operations provision is the company's estimate that it will
participate in 33 percent of these remediation costs.  The company's
estimated share of the costs is based on its assessment of the total clean-
up costs, its potential exposure, and the viability of other named PRPs.

<PAGE>                              13-32

In 1990, the company filed an action now pending in Luzerne County,
Pennsylvania alleging breach of contract and unjust enrichment arising out
of the termination of a construction contract for the Hazleton Gasification
Facility Expansion.  The suit named as defendants Continental Energy
Associates (CEA), the project owner; Continental Cogeneration Corporation
(CCC), the general partner of CEA; and Swiss Bank Corporation, the project
lender.  CEA and CCC filed a separate suit against the company which, as
amended, seeks damages for breach of contract, negligent design and
construction, negligent misrepresentation, fraud and tortious interference
with the contract of surety.  The two suits, along with a third action
commenced by CEA and CCC against the company's surety, the Insurance Company
of North America, have been consolidated.  Documents produced by CEA and CCC
during the course of discovery allege claims at an amount from approximately
$10 million to approximately $35 million.  However, the construction
contract contains a provision limiting damages to the value of the contract
(a net of approximately $10 million) which the company would seek to have
specifically enforced.  The company continues to vigorously assert its
claims and to deny any liability.

In late 1994, both CEA and CCC filed for protection from creditors under
Chapter 11 of the United States Bankruptcy Code.  In January 1995, the
Bankruptcy Court entered an order approving non-binding mediation of the
dispute with the company.  An initial mediation session held early in March,
1995 did not resolve the dispute.

If the lawsuit discussed above is sustained against the company, material
charges would be recorded in the company's financial statements.  However,
based upon the knowledge the company has of the lawsuit, management believes
the ultimate disposition of this matter will not result in material charges
to earnings in excess of amounts recorded in the financial statements.
        
Other claims and assertions made against the company will be resolved, in
the opinion of management, without material additional charges to earnings.

The company has asserted claims that management believes to be meritorious,
but no estimate can be made at present of the timing or the amount of
recovery.

Note 9: Retirement Plans

The company has several defined benefit plans covering substantially all
employees.  Benefits for the salaried plan are based on salary and years of
service, while hourly plans are based on negotiated benefits and years of
service.  The company's funding policy is to make contributions as are
necessary to provide assets sufficient to meet the benefits to be paid to
plan members in accordance with the requirements of the Employee Retirement
Income Security Act of 1974.  Plan assets are composed primarily of
government securities and corporate debt and equities.

The status of combined employee pension benefit plans as of December 31,
1994 and 1993 is shown below:

The sale of Dravo Basic Materials' assets resulted in the termination of
employment for essentially all Dravo Basic Materials employees and certain
executive and administrative employees of a subsidiary company.  As a result,
the company recognized a charge in 1994 for pension curtailment and special
termination benefits expense.  The components of 1994, 1993 and 1992 net

Note 10:  Postretirement and Postemployment Benefits

The company and certain subsidiaries provide health care and life insurance
benefits for retired employees.  Employees may become eligible for certain
benefits if they meet eligibility qualifications while working for the
company.  Currently, the company pays all cost increases for employees who
retired prior to 1985 and who have not elected to participate in a plan in
which they pay cost increases, in exchange for expanded benefits, in excess of
a specified amount.  For employees retiring after 1984, the company's
liability is limited to a fixed contribution amount for each participant or
dependent.  This amount is reduced significantly when the participant becomes
eligible for Medicare coverage.  The company has made no commitment to adjust
the amount of its contributions.

The company adopted the provisions of Statement of Financial Accounting
Standards No. 106, "Employers' Accounting for Postretirement Benefits Other
Than Pensions" (SFAS 106) effective January 1, 1993.  The statement requires
that an accrual be made for the expected cost of providing postretirement
benefits to the employee and the employee's beneficiaries and covered
dependents during the years that an employee renders employment services. 
Prior to adoption of SFAS 106, the company expensed postretirement benefits on
a pay-as-you-go basis.  The cost of postretirement benefits other than
pensions was $5.0 million in 1994, $4.9 million in 1993 and $4.5 million in
1992.  Expense in 1994 includes a $471,000 curtailment loss resulting from the
termination of essentially all Dravo Basic Materials employees and certain
executive and administrative employees of a subsidiary company due to the
Dravo Basic Materials asset sale.                                    

No funds are segregated for future postretirement obligations.  The company is
amortizing its accumulated postretirement benefit obligation (APBO) over a 20
year period.  The APBO was calculated using a discount rate of 8.55 percent
and a health care cost trend rate of 9.5 percent in 1995, gradually declining
to 6.5 percent in 2001.  An increase in the health care cost trend rate of one
percent would increase the APBO at December 31, 1994 by $1.1 million and the
total service and interest rate components of the 1994 postretirement benefit
cost by $109,000.

Postretirement benefit cost for 1994 and 1993 includes the following
components:

The company adopted the provisions of Statement of Financial Accounting
Standards No. 112, "Employers' Accounting for Postemployment Benefits" (SFAS
112) effective January 1, 1994.  SFAS 112 requires accrual of the estimated
cost of benefits provided by the employer to former or inactive employees,
including their beneficiaries and covered dependents, after employment but
before retirement.  A charge of $1.4 million was recorded in the first quarter
as a cumulative effect for a change in accounting principle to recognize the
company's estimated liability for postemployment benefits covered by SFAS 112.

Note 11: Stock Options, Stock Appreciation Rights and Performance Shares

Prices per share of outstanding common stock options and stock appreciation
rights (collectively, rights) at December 31, 1993 were $5.94 to $19.31.
During 1994 grants were awarded at a price of $11.69, rights were exercised at
$7.94 and $11.25 and rights were forfeited at $11.25.  Rights outstanding at
December 31, 1994 are exercisable at prices ranging from $5.94 to $19.31 per
share.  

Under the 1978, 1988 and 1994 Plans for executives and key employees, options
may be granted either alone or in tandem with related stock appreciation
rights, or stock appreciation rights may be granted separately.  The 1983 Plan
provides for the granting of options, stock appreciation rights (either
separate or in tandem with a related option) and performance shares.  The
price of stock options and the basis of stock appreciation rights so granted
is the fair market value on the date of grant.  Rights cannot be exercised
until one year after the grant date and expire ten years from date of grant. 
Any incremental value of stock appreciation rights and performance shares
granted is recognized as expense, while a decline in the market value of the
stock is recognized as a reduction in expense to the extent previously
recognized.  There was no change in the incremental value during the last
three years.  The exercise of options does not necessitate a charge or credit
to income.

No additional grants can be made from the 1978 or 1983 Plans, both of which
have expired.  There were no performance shares outstanding at December 31,
1994 and 1993.

The following summary shows the changes in outstanding rights:

The net change in the total valuation allowance for the years ended December
31, 1994 and 1993 was a decrease of $1.3 million and $22.4 million,
respectively.

The company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes," (SFAS 109) effective January 1, 1993.  The
statement requires that deferred income taxes reflect the tax consequences on
future years of differences between the tax bases of assets and liabilities
and their bases for financial reporting purposes.  In addition, SFAS 109
requires the recognition of future tax benefits, such as net operating loss
carryforwards (NOLs), to the extent that realization of such benefits are more
likely than not.  There was no cumulative effect of this accounting change at
the time of adoption.

The company had NOLs of approximately $181.5 million at December 31, 1994
because of losses associated with discontinued businesses.  These
carryforwards, which management expects will be fully utilized, expire as
follows:

</TABLE>
Under the provisions of SFAS 109, NOLs represent temporary differences that
enter into the calculation of deferred tax assets and liabilities.  At January
1, 1993, primarily as a result of the NOLs, the company was in a net deferred
tax asset position under SFAS 109.  The full amount of the deferred tax asset
was offset by a valuation allowance due to uncertainties associated with
unresolved issues related to discontinued operations.

In the fourth quarter of 1993, the company reduced its valuation allowance
resulting in a net deferred tax asset of $24.9 million.  Two factors
contributed to the reduction in the valuation allowance.  First was the
resolution of long-standing litigation between the company and the City of
Long Beach, Calif. regarding a waste-to-energy plant the company built for the
city and the ability to quantify, relying upon advice of legal counsel, the
potential financial impact of the remaining uncertainties associated with
previously discontinued operations.  Second, the company was awarded a
contract to supply American Electric Power's Gavin plant with 450,000 tons of
lime annually for 15 years commencing in 1995.  In addition,  the company had
pending the renewal of existing contracts which were finalized in 1994 and
raised utility lime sales backlog to $800 million.  With these contracts in
place, nearly 65 percent of the company's annual revenue will be generated by
long-term contracts.  As a result, the company believes that revenues and
income from its lime subsidiary can be reasonably projected over the life of
its long-term contracts for purposes of determining whether the realization of
the asset resulting from the utilization of NOLs in future years is more
likely than not.

Income projections for the contract lime business were based on historical
information adjusted for contract terms.  In 1993, the company projected
future income for its aggregates business based on the previous three year's
results, a period of low profitability for Dravo Basic Materials.  The
aggregates business assets were sold in 1994.  

In assessing the valuation allowance, estimates were made as to the potential
financial impact on the company should adverse judgments be rendered in the
remaining substantive uncertainties associated with discontinued operations. 
The significant uncertainties involve the

<PAGE>                              13-37

CEA litigation related to contract claims and environmental matters and are
discussed more fully in Note 8, Contingent Liabilities.  Management's position
in these cases is to vigorously pursue its claims and to contest the asserted
contract claims and liability for environmental clean-up.  In determining the
appropriate valuation allowance, however, management has used the upper limit
of the potential financial impact estimated for these matters.   The claims
against the company in the CEA matter, which management believes are grossly
overstated, exceed $10 million.
 
Supported by the company's forecast that it will generate sufficient future
taxable income to realize the entire deferred tax asset prior to expiration of
any NOLs results in the assessment that the realization of a $24.9 million net
deferred tax asset is more likely than not.  In order to fully realize the net
deferred tax asset, the company will need to generate future taxable income of
approximately $73.2 million prior to the expiration of the NOLs.  

Historically, Dravo Lime's cumulative taxable earnings for the past five years
total $64.8 million.  There can be no assurance, however, that the company
will generate any earnings or any specific level of continuing earnings.

The amount of the net deferred tax asset was not adjusted in 1994 due to
remaining uncertainties associated with the discontinued operations. 
Resolution of the Melaport litigation should, however, positively impact the
realization of the net deferred tax asset.

Tax benefits of $7.5 million for investment tax credits expiring in 1995 and
later are also being carried forward.

The company recorded an extraordinary credit of $1.6 million for the year
ended December 31, 1992, representing the recognition of income tax benefits
resulting from the utilization of net operating loss carryforwards for
financial reporting purposes.

Note 14:  Extraordinary Item

In conjunction with the sale of Dravo Basic Materials' assets, existing loan
agreements were substantially altered, including a $35 million reduction in
the amount available under a revolving credit facility.  Also, while
negotiating a $50 million financing agreement with Prudential Power Funding
for the Black River expansion, the company purchased a call option that
enabled it to prepay on May 17, 1995, without penalty, amounts outstanding
under the financing agreement.  At December 31, 1994, $19.9 million was
borrowed under the agreement.  Cash received from the Dravo Basic Materials
asset sale equalling the outstanding principal on the Prudential Power Funding
facility, interest through May 16, 1995 and an exit fee was placed in escrow. 
The company agreed that any additional drawings on the facility would also be
escrowed.  No additional drawings were made and, with Prudential Power
Funding's consent, the entire amount borrowed was prepaid on February 10,
1995.  The fees associated with these agreements were written off as
extraordinary items.

</TABLE>

The carrying amounts of notes receivable approximate fair value.  The fair
value of notes payable and the Series D Preference Stock is based upon the
amount of future cash flows associated with each instrument discounted using
the company's estimated borrowing rate for similar debt instruments of
comparable maturity.  The Preference Stock fair value also includes an
estimated factor to value the conversion feature.  The fair value of the
interest rate swap at December 31, 1993 is the estimated amount the company
would have received if it had terminated the agreement on that date.  The swap
was terminated in December, 1994.  The company does not intend to enter into
hedging transactions in the future.

Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument.  These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. 
Changes in assumptions could significantly affect the estimates.

Management's Report

The consolidated financial statements and other financial information
appearing in this Annual Report were prepared by the management of Dravo
Corporation, which is responsible for their integrity and objectivity.  These
financial statements have been prepared in conformity with generally accepted
accounting principles and include amounts that are based on informed judgments
and estimates of the expected effects of events and transactions.

Dravo maintains a system of internal controls to provide reasonable assurance
as to the reliability of the financial records and the protection of assets. 
This internal control system is supported by written policies and procedures
that communicate the details of the control system, by careful selection and
training of qualified personnel, and by a broad program of internal audits. 
In addition, the company's business ethics policy requires employees to
maintain the highest level of ethical standards in the conduct of the
company's business and their compliance is regularly monitored.

The company's financial statements have been audited by KPMG Peat Marwick LLP,
independent certified public accountants.  As stated in their report, their
audit was made in accordance with generally accepted auditing standards and
included such study and evaluation of the company's system of internal
accounting controls as they considered necessary to determine the nature,
timing and extent of the auditing procedures required for expressing an
opinion on the company's financial statements.

The Board of Directors, acting through its Audit Committee composed
exclusively of outside directors, reviews and monitors the company's financial
reports and accounting practices.  The Board of Directors, upon the
recommendation of the Audit Committee, appoints the independent certified
public accountants subject to ratification by the shareholders.  The Audit
Committee meets periodically with management, the internal auditors and the
independent auditors.  These meetings include discussions of internal
accounting control, results of audit work and the quality of financial
reporting.  Financial management as well as the internal auditors and
independent auditors have full and free access to the Audit Committee.










Independent Auditors' Report


The Board of Directors and Shareholders
Dravo Corporation:

We have audited the accompanying consolidated balance sheets of Dravo
Corporation and subsidiaries as of December 31, 1994 and 1993, and the related
consolidated statements of operations, retained earnings and cash flows for
each of the years in the three-year period ended December 31, 1994.  These
consolidated financial statements are the responsibility of the company's
management.  Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Dravo
Corporation and subsidiaries at December 31, 1994 and 1993, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1994, in conformity with generally accepted
accounting principles.

As discussed in Notes 10 and 13 to the consolidated financial statements, the
company adopted the method of accounting for postemployment benefits
prescribed by Statement of Financial Accounting Standards No. 112 in 1994 and
the methods of accounting for postretirement benefits other than pensions and
income taxes prescribed by Statements of Financial Accounting Standards Nos.
106 and 109, respectively, in 1993.

As discussed in Note 8 to the consolidated financial statements, a lawsuit and
certain claims and assertions have been brought against the company for
contract disputes and environmental costs, the outcome of which presently
cannot be determined.
