 PART I


Item 1.  Business

(a)  General Development of the Business

Dravo Corporation (the Registrant or company) 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 11 Stanwix Street, Pittsburgh, Pennsylvania 15222, and its
telephone number is 412-995-5500.  As used herein, the term Dravo includes its
consolidated subsidiaries unless otherwise indicated.

Dravo is primarily a lime company operating principally in the United States. 
Operations are carried on by a wholly-owned subsidiary, Dravo Lime Company
(Dravo Lime).  Activities include the production of lime for utility,
metallurgical, pulp & paper, municipal, construction and miscellaneous chemical
and industrial applications as well as the development and marketing of related
environmental technologies, products and services.  Three major utility
companies with whom the company has long-term contracts - American Electric
Power, Pennsylvania Power Company and  Cinergy Corp. - each accounted for 10
percent or more of consolidated revenue in 1997.  All reserves are located on
properties physically accessible for purposes of mining and processing
limestone into lime. Liabilities associated with non-natural resource
businesses sold or disposed of in the late 1980s are presented as a component
of discontinued operations in the financial statements.

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. 
With the completion of a fourth kiln at Maysville, Kentucky in 1997, annual
quicklime capacity totals approximately 3,400,000 tons.

The Maysville plant is a four kiln, 1,400,000 tons-per-year facility located
along the Ohio River and produces a material marketed under the trade name
Thiosorbic Lime.  Thiosorbic Lime has a chemistry ideally suited for removing
sulfur dioxide from power plant stack gases.  Most 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 four kiln operation in excess of eighty
years.

Dravo Lime's Black River facility produces Thiosorbic quicklime, high calcium
pebble and pulverized quicklime, and bulk and bagged hydrated lime.  Located
along the Ohio River at Butler, Kentucky, Black River has an annual quicklime
capacity of 1,400,000 tons-per-year.  Of that total, forty percent is committed
to utility companies and steel and paper customers under long-term contracts
with price escalation provisions.  Limestone reserves at Black River are
recovered from a 600-feet-deep underground mine.  At Black River's current
capacity, reserves are considered adequate to sustain production levels for
more than seventy years.

                                    -3-

Item 1.  Business (continued)

The company's Longview facility, located near Birmingham, Alabama, has three
kilns that produce 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.  Longview's
annual lime production capacity is approximately 570,000 tons-per-year.  The
company has secured the necessary permits and plans to start construction of a
fourth kiln at Longview in 1998.  In early 1997, a number of land parcels
adjacent to the Longview quarry were purchased that doubled limestone reserves.
Recoverable reserves are estimated to last approximately forty-five years at
the current quarry production rate.  Although it will not be necessary until
the distant future, Longview could be converted to an underground mine if a
further extension of reserves is necessary.

An aggregates processing plant at the Longview facility annually produces
between 500,000 to 1,000,000 tons of aggregates.  A benefit of this
installation is to make a marketable by-product out of limestone that is
chemically unsuitable for lime production, thereby reducing the cost Dravo Lime
incurs to recover the high calcium limestone reserves that are beneath the
aggregate quality material.  A major aggregates company has the exclusive
distributorship rights for certain aggregates by-products produced by the
company.

Dravo Lime products are distributed through quicklime distribution terminals
located in Donora and Monaca, Pennsylvania; Porterfield, Ohio; Brunswick,
Georgia; and Tampa, Fort Lauderdale, Jacksonville 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, strategically located reserves and technical expertise in flue gas
treatment technologies give it certain competitive advantages.

Dravo's research and development expenditures were $6.5 million in 1997 and
$3.7 million in 1996.  Expenditures in 1997 and 1996 included $4.2 million and
$1.0 million, respectively, related to construction of the first commercial
scale ThioClear flue gas desulfurization (FGD) system.  ThioClear is a second
generation proprietary FGD technology.  The system's construction costs plus
interest will be repaid to the company by the owner, AES Beaver Valley, Inc.
Research and development spending in 1998 is expected to total $2.5 million. 
The company anticipates the research, much of which is being conducted jointly
with utility customers, will lower both the capital and operating costs
associated with flue gas treatment.  Other research projects are aimed at
developing proprietary technologies for use in reducing stack gas emissions of
combined SOx/NOx and air toxins while recovering and processing 


                                   -4-

Item 1. Business (continued)

salable by-products.  Dravo believes that in this field its long-term
contracts, accumulated experience and technical skill represent significant
competitive advantages.

With the exception  of its research and development capabilities, 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.

Dravo Corporation is a domestic natural resource business primarily involved in
the production, processing and supply of lime for environmental, metallurgical,
pulp & paper, municipal, construction and miscellaneous chemical and industrial
applications as well as the development and marketing of related environmental
technologies, products and services.  Standards promulgated by the 1990 Clean
Air Act Amendments bolstered Dravo's position as the world's leading producer
of lime for FGD applications.

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, 1997 issued preference and common shares were 218,386
and 15,103,249, respectively and there were 397,413 shares of common stock held
in the treasury.

Four series of preference stock have been established by resolutions of the
Board of Directors:  $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; and $12.35 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 18,386 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.  The Board of Directors did not extend the rights to issue Series
C stock, pursuant to the Shareholders' Rights Agreement, past the April 17,
1996 expiration date.  Other series of preference stock may be created by
resolution 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

                                   -8-

Dividend Rights (continued)

stock ranking after 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 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 25 and 26 of the 1997 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; 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.

                                    -9-

Item 5.  Market for the Registrant's Common Stock and Related Stockholder  
Matters (continued)

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 D Preference Stock may be redeemed in whole
or in part at the option of Dravo 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, the Series B
Preference Stock or the Series D Preference Stock.

Item 5.  Market for the Registrant's Common Stock and Related Stockholder  
Matters (continued)

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 common
stock.

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.  

The holders of the preference stock who comply with applicable provisions of
law and object to a merger or consolidation involving Dravo shall have all of
the legal rights of objecting shareholders in a merger or consolidation whether
or not they constitute a class otherwise entitled to such rights. 

The transfer agent and registrar for the common stock is Continental Stock
Transfer & Trust Company, New York, NY.

The Board of Directors and Shareholders
Dravo Corporation:

Under date of January 21, 1998, we reported on the consolidated balance sheets
of Dravo Corporation and subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of earnings, retained earnings, and cash
flows for each of the years in the three-year period ended December 31, 1997,
as contained in the 1997 annual report to shareholders.  These consolidated
financial statements and our report thereon are incorporated by reference in
the annual report on Form 10-K for the year 1997.  In connection with our
audits of the aforementioned consolidated financial statements, we also
audited the related financial statement schedule as listed in the accompanying

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, presents
fairly, in all material respects, the information set forth therein.

Note 2:  Income Taxes

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.

                                   -29-

Note 2:  Income Taxes (continued)


The income tax benefit for the years ended December 31 are

The tax effects of temporary differences that give rise to significant
portions of the deferred tax assets and deferred tax liabilities at December
31 are as follows:

Management believes it is more likely than not that the net deferred tax asset
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 $98 million prior to the expiration of its net
operating loss carryforwards.  The company's cumulative taxable earnings for
the past two years total $22.3 million.

FINANCIAL REVIEW

OVERVIEW


Revenue and gross profit in 1997 exceeded 1996 levels as did net earnings.  The
net earnings improvement resulted from recording a tax benefit for tax net
operating loss carryforwards.  Mitigating this benefit were a major flood in
the first quarter that disrupted shipments for an extended period and stopped
the company from loading and its customers from unloading barges, overhead
charges in the fourth quarter for severance costs associated with reducing
executive staff size, expenses for an operations and financial review, and
investment banking fees.

Net earnings for the year were $15.1 million, or $0.85 per diluted share,
compared to $14.1 million, or $0.78 per diluted share, in 1996.  The tax
benefit improved 1997's earnings per share by approximately $0.32 while the
overhead charges reduced earnings per share by approximately $0.13.  Earnings
for 1995 were $11.0 million, or $0.57 per diluted share.

During 1997, Dravo completed three major capital projects that position the
company for future growth.  Early in the year, 27 million tons of high-calcium
reserves were acquired adjacent to the Longview plant in northern Alabama.  In
midyear, a new kiln at the Maysville plant in northern Kentucky started
producing utility grade lime with annual capacity of 350,000 tons.  A major
refurbishing of an existing kiln at the Black River plant, also located in
northern Kentucky, was completed near year-end.  Production from the
refurbished kiln will primarily supply the non-utility lime markets.


RESULTS OF OPERATIONS

CONTINUING OPERATIONS

Revenue: Revenue of $162.5 million was $4.3 million higher than in 1996. Most
of the increase was due to strong commercial market lime demand in the
southeastern United States.  Demand for precipitated calcium carbonate, a
product derived from lime and used by the pulp & paper industry, was
particularly strong.  Utility lime sales were negatively affected by a
lightning strike that severely damaged  equipment  at a major customer's
generating station and impacted lime deliveries for several months.

Revenue in 1996 was $12.1 million higher than 1995.  As in 1997, much of the
increase was attributable to higher sales in the southeast market region. 
Strong commercial demand, augmented by the sale of brokered lime

                                  13-13
as demand
exceeded production capacity, contributed to the revenue increase.  Revenue
also increased because a new aggregates plant, completed at Longview in late
1995, converts quarried limestone chemically unsuitable for lime production
into crushed stone aggregate byproducts.  Utility lime sales were dampened by
prolonged delivery interruptions to a major utility customer caused by problems
at the customer's generating station and by a reduction in over-scrubbing due
to a drop in the value of sulfur dioxide (SO2) emission allowances.

Costs and Expenses: Gross profit of $40.8 million was up $867,000 from 1996
while 1996 was up $3.4 million over 1995.  Gross profit margins in all three
years were maintained at the 25 percent level despite less demand from
utilities in 1997 and 1996 than required to maximize production and fully
utilize the company's new utility lime kilns.  Gross profit and margins were
also suppressed by the need to purchase commercial-grade lime in the southeast
region as demand surpassed production capacity.

Selling expenses were $5.1 million, $4.6 million and $5.0 million in 1997, 1996
and 1995, respectively.  Part of the increase in 1997 was for marketing of
Sorbalit  technology, a system for acid gas and air toxins removal for which
the company is the exclusive North America licensee, and development costs for
a proprietary nitrous oxide removal process.  Selling expenses vary depending
on research and development expense 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, governmental
agencies, public utilities or private groups may reimburse all or a portion of
a project's costs.  Third-party billings are treated as a reduction in costs. 
Research and development costs and billings to third parties are detailed in
Note 15, Research and Development, in the Notes to Consolidated Financial
Statements.

General and administrative expenses were $2.3 million higher in 1997 than 1996.

The increase was principally due to an accrual for severance costs associated
with reducing executive staff size, consulting fees for an operations and
financial review and expenses related to an investment banking review to
explore merger and acquisition opportunities.  General and administrative
expenses were essentially unchanged in 1996 versus 1995.  A $1.3 million
pension expense increase was more than offset by a $1.7 million drop in retiree
medical costs.  The company began participating in various Medicare HMOs in
1996 and fixed the amount it contributes toward the cost of retiree medical
coverage.

Equity in earnings of joint ventures includes the company's share in three
50-percent owned joint ventures: a contract phosphate rock mining operation in
Idaho, a small contract coke operation in Wyoming, and an activated carbon
production plant in New York.  The phosphate mining operation's profitability
varies depending on mining conditions and the requirements of its single
contract customer.  Earnings from joint ventures were higher in 1997 compared
to 1996 due to strong phosphate demand; however, a loss of $130,000 was
recorded on the activated carbon venture that started operations in late 1997. 
Joint venture earnings were higher in 1996 than 1995 due to strong phosphate
demand and a return to more normal maintenance expense.

Other income (expense) includes the gain or loss on the disposal of property,
plant and equipment.  In 1997, 1996 and 1995, the amounts were insignificant.

Interest income of $235,000 was $665,000 lower than in 1996.  Last year's
amount included interest on a refund received from a state taxing authority
after the company filed amended tax returns based on a revised interpretation
of the state tax code.

Interest expense in 1997 was $7.0 million, $599,000 more than 1996, due to
higher debt levels.  Capital expenditures totaled $27.2 million and were
partially funded by debt.  Debt increased $14.4 million from year-end 1996 to
year-end 1997.  In 1996, interest expense increased $1.6 million from 1995,
also because of higher debt levels.  The proceeds from the sale of the assets
of Dravo Basic Materials (DBM), the company's construction aggregates
operation, enabled the company to reduce debt, including amounts borrowed under
a revolving line of credit, $85.5 million at the beginning of 1995.  The
revolver debt level subsequently increased throughout 1995 as the company
satisfied retained DBM liabilities, principally accounts payable, and completed
a $60 million expansion project at Black River.

                                    13-14

Current accounting standards require 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,
future tax benefits, such as tax net operating loss carryforwards (NOLs), are
required to be recognized to the extent that realization of such benefits is
more likely than not.  A valuation allowance is established for those benefits
that do not meet the more likely than not criteria. The company had NOLs of
approximately $173 million at December 31, 1997.  Management continually
evaluates the recorded deferred tax valuation allowance and believes that, due
to the large portion of revenue generated by long-term supply contracts and
taxable income generated by the company since it started operating solely as a
lime company three years ago, income can be reasonably projected for purposes
of determining whether the realization of the asset resulting from the use of
NOLs in future years is more likely than not.   As a result, the company
reduced its valuation allowance in 1997 and recorded a net tax benefit of $4.1
million.  The amount of the net deferred tax asset, $30 million, reflects that
portion of the gross deferred tax asset that management believes, based on
current income projections and tax preference item estimates, is more likely
than not will be realized.

The company's effective tax rate in the future will be partially determined by
the amount actual taxable income differs from the taxable income level assumed
in determining the net tax asset.  The company anticipates an effective tax
rate in 1998 of approximately 20 percent.  The effective tax rate is used for
financial reporting purposes only and will not affect actual taxes paid, which
will remain low due to NOL utilization.

The company's income tax expense was zero in 1996 because of NOLs that
sheltered the company's income from both federal and state income taxes. Income
tax expense of $340,000 in 1995 was for estimated state income taxes.

Effects of Inflation:  Inflation rates have been low during the past three
years and as a result have not affected 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

Discontinued operations had a net cash outlay of $4.1 million in 1997 for
non-cancelable leases, environmental, insurance, legal and other matters, all
of
which were covered by a previously established reserve.  In 1996, the company
collected a $7.3 million judgment and interest awarded by a Georgia court
related to a contract dispute with a discontinued engineering subsidiary's
subcontractor.  Also in 1996, an issue with one of the company's insurance
carriers regarding deductible limits on asbestos and other retroactive claim
adjustments was resolved with the insurance carrier refunding $2.6 million in
past payments.  The discontinued operations provision was credited $1.1 million
for the insurance refunds.  The company received a $2.2 million refund from a
state taxing authority in 1996 after the company filed amended income tax
returns based on its current interpretation of the state tax code.  The refund
included $575,000 recorded as interest income.  The original tax returns were
filed on a separate basis and included only the results of entities that had
operations in the state.  These entities were, for the most part, profitable
and paid income taxes.  The amended tax returns were filed on a combined basis,
which included an apportionment of the results of all the company's operations,
including losses from discontinued operations.  The amended returns reported
tax losses instead of taxable income and resulted in the refund, of which $1.7
million was credited to the discontinued operations reserve in 1996.  The
amended returns also generated a state tax NOL that can be used to shelter
future taxable income.


FINANCIAL POSITION AND LIQUIDITY

Working capital at year-end 1997 was $3.9 million, down $4.6 million from
December 31, 1996.  In July 1997, the company converted $17.0 million of
revolver debt, classified as long-term at year-end 1996, to a 5-year term note
with quarterly principal payments of $850,000.  In addition, $5.0 million of
Series D Preference Stock is scheduled to be redeemed on October 1, 1998 and is
now classified as a current liability.  Long-term debt borrowed under the
company's revolving credit/letter of credit facility increased primarily due to
capital expenditures.

                                  13-15

A $53.0 million revolving credit/letter of credit facility is provided by a
consortium of lenders that includes Regions Bank of Alabama; PNC Bank, N.A.;
and Bank of America Illinois.  Interest on the revolver equals either the base
lending rate of Regions Financial Corporation, Regions Bank of Alabama's
parent, or, at the option of the company, the Eurodollar interest rate plus 2
percent.  The facility expires July 31, 1999, but includes renewal provisions.

Obligations under the revolving credit/letter of 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 Dravo Lime Company's 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 to maintain minimum net worth levels and fixed charge
ratios on a consolidated basis; restrict incurrence of debt, liens and lease
obligations; restrict the sale of significant assets; and limit payment of
dividends.  These restrictions are not expected to have an adverse impact on
the company's ability to meet its obligations.

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 the revolving credit agreement.  The company
has sufficient funds and borrowing capacity to meet its anticipated operating
and normal capital needs.  A portion of a planned major expansion at Longview
for a new kiln and ancillary equipment will require additional outside funding.

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.  The remaining discontinued operations liabilities will not have
a material adverse impact on liquidity because expected cash payments are
spread over several years.


DIVIDENDS

The company's loan agreement contains a covenant that limits common stock
dividend payments.  A common stock dividend may not be declared if that
dividend plus all other common dividends paid after December 31, 1995 exceeds
$5.0 million plus 25 percent of net earnings available for common stock after
December 31, 1995 less cumulative stock buy-backs after December 31, 1995.  Net
earnings exclude gains from the sale of capital assets, extraordinary gains and
unremitted earnings of joint ventures.  At December 31, 1997, assuming no other
financial or debt covenant restrictions, common stock dividends were limited to
$9.0 million.  No dividends on common stock were declared.  Annual dividends on
the $12.35 cumulative, convertible, exchangeable, Series D Preference Stock and
the $2.475 cumulative, convertible Series B Preference Stock were declared
quarterly throughout 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 1997 and 1996 as reported for New York
Stock Exchange composite transactions were:

OUTLOOK

Continuing operations: Dravo is highly leveraged, both operationally and
financially.  Operationally, maximizing output is critical while operating
production facilities as efficiently as possible. To reach that goal,
additional business must be booked that will fully utilize existing utility
lime production capacity at the Maysville and Black River plants.  A
broad-based marketing program is aimed at making all coal-fired power plants in
the market area served by the two northern Kentucky plants aware of the
advantages of lime-based scrubbing.

                                  13-16

Marketing efforts are directed at convincing
potential customers that converting to a lime-based flue gas desulfurization
(FGD) system is more economical than either burning low-sulfur coal or using a
limestone or sodium-based FGD system to scrub stack gas emissions.  And
companies currently using lime-based FGD systems are being apprised of the
reduction in scrubbing costs they will experience by converting to the
company's proprietary Thioclear  process.

Since the late 1980s, the pulp & paper industry has significantly increased its
consumption of lime.  Lime is a raw material used in the production of
precipitated calcium carbonate (PCC), an alkaline-based filler material used to
produce white paper.  The company recently renewed for 10 years a supply
contract with a major precipitated calcium carbonate producer.  Under the
contract, the company will provide lime to PCC production plants throughout the
southeast.  This long-term supply agreement will provide the underpinning for
adding a new 300,000-ton-per-year kiln and ancillary equipment at the company's
Longview plant located near Birmingham, AL.

Financially, the company's goal is to reduce its overall debt level.  While
significant parts of the major expansions completed at Black River and
Maysville over the last four years were funded from operational cash flow, a
portion was funded with debt.  Debt and preferred stock issued in the late
1980s during the company's exit from various discontinued operations carry high
interest and dividend rates. A management goal is to reduce this high cost debt
as quickly as possible, either by making the required scheduled principal
payments and mandatory preferred stock redemptions, or through a debt
restructuring with less onerous interest rates.

Various financial and process control software is used to manage and operate
business operations.  The company is addressing the year 2000 software
compatibility issue and has already replaced numerous financial systems with
year 2000 compliant software.  While this issue will require significant time
and effort, the expense is not expected to be material.

In 1997, the company conducted an investment banking review of strategic
alternatives for accelerating growth that included merger, acquisition or other
opportunities advantageous to the interest of the company's shareholders.  As
previously reported, the review did not produce a transaction.  The company is
pursuing its long-term plan of internal expansion, development of new
businesses based on proprietary technologies and selective merger and/or
acquisition opportunities.

In June 1997 Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS 130) was issued effective for fiscal years
beginning after December 15, 1997.  SFAS 130 requires the reporting by major
component and as a single total the change in equity during the period from
nonowner sources, such as minimum pension liability adjustments.  Adoption of
SFAS 130 will not impact the company's consolidated balance sheet, statement of
earnings or cash flows, and any effect will be limited to the form and content
of its disclosure. 

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 cleanup of soil and groundwater contamination
at four Hastings area sub-sites.  In January 1997, the company reached a
monetary settlement with the EPA regarding one sub-site in exchange for the EPA
excluding the company from any further liability at that sub-site. See Note 8,
Contingent Liabilities, in the Notes to Consolidated Financial Statements for
further discussion of the company's estimate of total cleanup costs and its
share of those costs.

Management estimated the assets and liabilities associated with discontinued
operations and believes the provision for losses on discontinued operations is
adequate at this time.  If these estimates are inaccurate or should other
unforeseen developments occur, a future additional provision for discontinued
operations could be required.

Forward-looking statements:  Investors are cautioned that statements which
relate to the future are, by their nature, uncertain and dependent upon
numerous contingencies, any of which could cause actual results and events to
differ materially from those indicated in such forward-looking statements. 
This is particularly true of forecasting income levels, cash flows, the success
of efforts to commercially develop new technologies, and regarding estimates of
the ultimate cost of environmental remediation, including participation in such
costs by other PRPs.

            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 subsidiary is Dravo Lime Company, one of the nation's largest
lime producers.  Lime is sold to electric utility companies under long-term
contracts and to the pulp & paper, metals, chemicals, municipal and construction
markets.

Three major utility companies, with whom the company has long-term contracts,
each accounted for more than 10 percent of consolidated revenue in 1997. The
company completed a transaction on December 30, 1994 in which it sold
substantially all the assets and certain liabilities of Dravo Basic Materials
Company, Inc. (DBM), a former principal subsidiary.  The December 31, 1995
consolidated statement of cash flows includes cash received from the DBM
transaction and the payment of retained obligations, primarily accounts payable.

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

Use of Estimates:  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

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. Depreciation is computed using the straight-line method over
estimated useful lives of 10 to 30 years for buildings and 3 to 30 years for
machinery and equipment. Expenditures for maintenance and repairs that 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.

Income Taxes:  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.  Future tax benefits, such as net operating loss
carryforwards, are recognized to the extent that realization of such benefits
are more likely than not.

Earnings Per Share:  In December 1997, the company adopted Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS 128). SFAS
128 requires the presentation of basic and diluted earnings per share on
financial statements issued for periods ending after December 15, 1997.  SFAS
128 also requires restatement of all prior-period earnings per share data
presented.  Basic earnings per share is based on net earnings less preference
dividends declared in the year (net earnings available to common stock),
divided by the weighted average sum of common shares outstanding during the
year.  Diluted earnings per share is based on net earnings available to common
stock, divided by the sum of the weighted average number of common shares
outstanding during the year and common share equivalents, unless inclusion of
common share equivalents would be anti-dilutive.  Common share equivalents are
calculated using the treasury stock method.

Stock-based compensation: Stock-based compensation is accounted for using the
intrinsic value approach as prescribed by Accounting Principles Board Opinion

Environmental Costs:  Liabilities are recorded when environmental assessments
or remedial efforts are probable and the costs can be reasonably estimated. 
Such estimates are adjusted, if necessary, as new remediation requirements are
defined or as more information becomes available.

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 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 assets and liabilities sold to Martin Marietta were removed from the
company's December 31, 1994 balance sheet, and a corresponding receivable from
the sale of DBM of $120.5 million was recorded.  The receivable was collected
and a majority of the obligations were paid in 1995 as reflected in the
statement of cash flows.

</TABLE>

The variable rate revolving line of credit is a $53.0 million revolving
credit/letter of credit facility with Regions Bank of Alabama; PNC Bank, N.A.;
and Bank of America Illinois.  Interest on the revolver equals either the base
lending rate of Regions Financial Corporation, Regions Bank of Alabama's
parent, or, at the option of the company, the Eurodollar interest rate plus 2
percent.  The facility expires July 31, 1999, but includes renewal provisions.

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

                                    13-25

In 1997, the company converted $17.0 million borrowed under the line of credit
to a 5-year variable rate term note.  Principal payments of $850,000 are paid
quarterly with interest equal to the Eurodollar rate plus 2 percent.

Obligations under the revolving credit/letter of credit facility, the 11.21
percent term notes and the variable rate term note are secured by a pledge of
the stock of Dravo Lime Company and Dravo Basic Materials Company along with
Dravo Lime Company's 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
to maintain minimum net worth levels and fixed charge ratios on a consolidated
basis; restrict incurrence of debt, liens and lease obligations; restrict the
sale of significant assets; and limit payment of dividends.  At December 31,
1997, assuming no other financial or debt covenant restrictions, common stock
dividends were limited to $9.0 million.  No dividends on common stock were
declared.

Assets pledged under certain notes and leases had a book value of $150.2
million at December 31, 1997.

Amounts payable on long-term debt, excluding the variable rate revolving line
of credit, due in 1998 and thereafter are: 1998, $9.7 million; 1999, $9.7
million; 2000, $9.7 million; 2001, $9.6 million; 2002, $8.8 million; and after
2002, $0.5 million.

Note 6:  Redeemable Preference Stock

The company has outstanding 200,000 shares of cumulative, convertible,
exchangeable Series D Preference Stock.  Cumulative annual dividends of $12.35
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 Series D Preference Stock, in whole or in part, 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, is 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 October 1, 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 all accumulated and unpaid dividends.

The company had outstanding 18,386 and 20,386 shares of cumulative, convertible
Series B Preference Stock on December 31, 1997 and 1996, 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.

A joint venture phosphate mining operation, in which the company is a
50-percent partner, has credit available under a bank loan agreement for
equipment purchases.  The company would be required to repay the entire loan in
the event of a failure of both the joint venture and the other partner.  At
December 31, 1997 and 1996, $2.1 million and $3.1 million, respectively, was
borrowed under the agreement.

Outstanding letters of credit totaled $4.8 million at December 31, 1997 and
1996.

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 cleanup of soil and groundwater contamination at four sub-sites
in Hastings, NE.  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).
 
Regarding the first sub-site, the company participated in an EPA-initiated
allocation proceeding for a municipal landfill sub-site to allocate shares of
liability for past response costs and costs of a proposed cap of the landfill. 
As part of this proceeding, the allocator conducted a mediation session that
resulted in a settlement among the EPA and the PRPs.  Pursuant to the
settlement, the company agreed to pay 14.33 percent of the EPA's past costs and
the estimated costs of the cap and its maintenance.  A Consent Decree
incorporating the settlement and requiring the private parties to pay for,
construct and maintain the cap is awaiting the approval of the United States
Justice Department and ultimately the Federal District Court.  In exchange, the
company received contribution protection against third-party claims as well as
a covenant from the EPA not to sue for its past and future response costs at
this sub-site and matters covered by the settlement.
                             
The company has also been notified by the EPA that the EPA considers it a PRP
at another municipal landfill in Hastings.  At least three other parties
(including the City of Hastings) are considered by the EPA to be PRPs at this
second sub-site.  At this sub-site, the company has concluded that the City of
Hastings is primarily responsible for proper closure of the landfill and the
remediation of any release of hazardous substances.  The EPA has conducted the
remedial investigation for this sub-site.  The company, along with some of the
other PRPs, including the City of Hastings, is considering a proposal from the
EPA to conduct the feasibility study.  In 1997, the company and the other PRPs
at this sub-site received a demand from the EPA that they pay the EPA's
response costs at this sub-site through September 30, 1994.  The company and
some of the other PRPs, including the City of Hastings, intend to examine these
costs to determine whether or not they are valid. 

With respect to the third sub-site, the company and two other PRPs have been
served with administrative orders directing them to undertake soil remediation
and interim groundwater remediation at that sub-site.  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.
    
In 1997, the company and the other PRPs at this sub-site received a demand from
the EPA that they pay the EPA's response costs at this sub-site through
September 30, 1994.  The company and some of the other PRPs intend to examine
these costs to determine whether or not they are valid.  A total of five
parties have been named by the EPA as PRPs at this sub-site, but two of them
have been granted de minimis status.  The company believes other persons should
also be named as PRPs.

                                    13-27

The fourth sub-site is a former naval ammunition depot that was subsequently
converted to an industrial park.  The company and its predecessor owned and
operated a manufacturing facility in this industrial park.  To date, the
company's investigation indicates that it did not cause the release of
hazardous substances at this sub-site during the time it owned and operated the
facility. The United States has undertaken to conduct the remediation of this
sub-site.
     
In addition to sub-site cleanup, the EPA is seeking a cleanup of area-wide
contamination associated with all of the sub-sites in and around Hastings.  The
company, along with other Hastings PRPs, has recommended that the EPA adopt
institutional controls as the area-wide remedy in Hastings. The EPA has
completed an area-wide remedial investigation and has asked the PRPs to agree
to perform a feasibility study to determine whether institutional controls or
another remedial alternative should be undertaken.  The company, along with
eight to ten other PRPs, is considering this proposal.  An acceptable area-wide
remediation plan could result in interim remedies at the sub-sites becoming
final remedies.  In 1997, the company and the other area-wide PRPs received a
demand from the EPA that they pay the EPA's area-wide response costs through
September 30, 1994.  The company and some of the other area-wide PRPs intend to
examine these costs to determine whether or not they are valid.
   
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 sub-site.  On motion of the defendant insurance carriers, the
suit was transferred to the District Court for the Western District of
Pennsylvania on October 31, 1996.  The company has 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 second
and fourth sub-sites.
   
Estimated future cleanup costs at the third sub-site, including capital outlays
and maintenance costs for soil and groundwater remediation of approximately
$6.2 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 and a pro rata share of
the EPA's past response costs. The company's estimated share of the costs is
based on its assessment of the total cleanup costs, its potential exposure, and
the viability of other named PRPs.  These estimates are, by their nature,
uncertain and dependent upon numerous factors, any of which could cause actual
results to differ materially from projected amounts.
   
Other claims and assertions made against the company will be resolved, in the
opinion of management, without material additional charges to earnings.

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 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.

In 1996, the company changed the date it measures plan assets and obligations
to September 30.  The following table reconciles the plans' funded status as of
September 30, 1997 and 1996 to the amounts recognized in the company's balance
sheets at December 31, 1997 and 1996, respectively:

Note 10:  Postretirement and Postemployment Benefits

The company provides 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. The company
participates in various Medicare HMOs.  Retirees have the option of joining a
Medicare HMO or selecting other health care plans; however, the company
contributes a fixed amount toward the cost of the coverage regardless
of the plan selected.  The company accrues for the expected cost of providing
postretirement benefits to the employee and the employee's beneficiaries and
covered dependents during the years of employment service. 

                                   13-29

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 7.25 percent
and a health care cost trend rate of 7.5 percent in 1998, gradually declining
to 5.25 percent in 2001.  An increase in the health care cost trend rate of 1
percent would increase the APBO at September 30, 1997 by $132,000 and the total
service and interest rate components of the 1997 postretirement benefit cost by
$10,000.

Postretirement benefit cost for 1997, 1996 and 1995 includes the following
components:

In 1996, the company changed the date it measures plan obligations to September
30.  The following table reconciles the plans' funded status as of September
30, 1997 and 1996 to the amounts recognized in the company's balance sheets at
December 31, 1997 and 1996, respectively:

The company accrued $2.6 million and $1.3 million at December 31, 1997 and
1996, respectively, for the estimated cost of benefits to be provided to former
or inactive employees, including their beneficiaries and covered dependents,
after employment but before retirement.  Postemployment benefit costs in 1997,
1996 and 1995 were $1.7 million, $300,000 and $300,000, respectively.  The 1997
expense included $1.3 million for severance costs associated with reducing
executive staff size.

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

The company has awarded to executives and key employees common stock options
and stock appreciation rights (collectively, rights) under four plans: the 1978
Plan, the 1983 Plan, the 1988 Plan and the 1994 Plan.  Under the 1988 and 1994
Plans, 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 provided for the granting of options, stock appreciation rights
(either separately 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 average of the company's high and low market prices on the grant
date.  Rights cannot be exercised until one year after the grant date and
expire 10 years from date of grant.  No additional grants can be made from the
1978 or 1983 Plans.  There were no performance shares outstanding at December
31, 1997 and 1996.

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.

Stock option grants are accounted for using the intrinsic value approach;
therefore no expense was recognized with respect to such options.  As required
by current accounting standards, an estimate of the fair value of stock options
granted in 1997, 1996 and 1995 was made

                                    13-30

using the Black-Scholes option pricing
model.  The Black-Scholes model requires the input of highly subjective
assumptions, including stock price volatility, expected option life and
forfeiture rates, all of which can materially affect the fair value estimates. 
The weighted average fair value estimates determined by the model and the
assumptions used are presented below:

The net change in the total valuation allowance for the years ended December
31, 1997 and 1996 was a decrease of $11.4 million and $1.6 million,
respectively.

The company had NOLs of approximately $173 million at December 31, 1997 because
of losses associated with discontinued businesses.  These NOLs expire as

The company has an alternative minimum tax credit carryforward of $750,000. 
This credit may be utilized to reduce the company's regular tax liability down
to its alternative minimum tax liability in future tax years and has an
unlimited life.

Tax benefits of $666,000 for investment tax credits expiring in 1998 and later
are also being carried forward.

Current accounting standards require 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,
future tax benefits, such as NOLs, are required to be recognized to the extent
that realization of such benefits is more likely than not.  A valuation
allowance is established for those benefits that do not meet the more likely
than not criteria.  

The company had NOLs of approximately $173 million at December 31, 1997.
Management continually evaluates the recorded deferred tax valuation allowance
and believes that, due to the large portion of revenue generated by long-term
supply contracts and taxable income generated by the company since it started
operating solely as a lime company three years ago, income can be reasonably
projected for purposes of determining whether the realization of the asset
resulting from the use of NOLs in future years is more likely than not.   As a
result, the company reduced its valuation allowance in 1997 and recorded a net
tax benefit of $4.1 million.  The amount of the net deferred tax asset, $30
million, reflects that portion of the gross deferred tax asset that management
believes, based on current income projections and tax preference item
estimates, will more likely than not be realized.

Income projections for the contract lime business are based on historical
information adjusted for contract terms. In order to fully realize the net
deferred tax asset, the company will need to generate future taxable income of
approximately $98 million prior to the expiration of the NOLs.  The company's
cumulative taxable earnings for the past two years total $22.3 million. 

Note 14: Fair Value of Financial Instruments

The fair value of financial instruments without extended maturities equals
their carrying values.  The estimated fair value of financial instruments with
extended maturities at December 31 is presented below:

Series D preference stock           20,000     22,561     20,000     22,533
</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.

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.

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, 1997 and 1996, and the related

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

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

Dravo Letterhead

January 30, 1998

Mr. Earl J. Bellisario
C/O Dravo Corporation
3600 One Oliver Plaza
Pittsburgh, PA 15222

Dear Earl:

To help ensure your continued dedication as an employee of Dravo 
Corporation (the "Company"), the Company desires to provide for, among other 
things, the payment of two years' compensation and benefits if your employment 
is terminated by the Company without cause. In exchange for this assurance, you 
are willing to agree to not compete with the Company for two years after the 
termination of your employment. The following sets forth the details of this
agreement.

1.	Salary and Benefit Continuation. The Company agrees that if your 
employment with the Company is terminated by the Company without cause, the 
Company will continue to pay your salary and provide for your benefits for two 
years following the date of termination as if you were still an employee of the 
Company (including for purposes of eligibility, coverage, vesting and benefit 
provisions under the Company's benefit plans) during that period. You are not 
required to mitigate this payment by seeking other employment and these 
amounts are payable to your estate if you die during the two year period.

2.    Stock Options. The Company agrees that if your employment with 
the Company is terminated by the Company without cause, you will continue to 
hold all stock options and restricted stock held by you on the date of your 
termination as if you were an employee of the Company for two years thereafter, 
and at the end of that two year period, you will be deemed to have retired from 
the Company for purposes of the plans pursuant to which the stock options and 
restricted stock were issued.

3. SERP and EBP. The benefits credited to you under the 
Company's Supplemental Executive Retirement Plan (SERP) and the Executive 
Benefit Plan (EBP) (including any additional age and service credit by reason
ofthe benefit continuation under paragraph 1 of this letter) shall be fully 
vested and nonforfeitable through the date of any adverse amendment or
termination of those plans, provided, that you will not be entitled to any 
benefits under those plans if your employment is terminated by the Company 
for cause.  In addition, your "retirement" under the EBP is deemed to be 
approved by the Board's Compensation Committee. The Company will pay benefits 
under the SERP and the EBP in accordance with the terms of those plans, but if
your salary is continuing under paragraph 1 of this letter, the Company will 
begin to pay benefits under the SERP and EBP at the end of your two year salary
continuation period. Further, if your salary is continuing under paragraph 1 of
this letter, you may 
elect, during the  first 12 months following your termination, to receive a 
lump sum of your SERP and EBP benefits at the end of your two-year salary 
continuation period.

                                    10-1

4.    Noncompete. You agree that for a period of two years after the 
termination of your employment with the Company for any reason, you will not 
have an ownership interest in or render services to (as an employee, consultant 
or otherwise), any company that is engaged in (a) the mining, production, 
marketing and  sale of limestone or lime, including those companies listed on 
Exhibit A and their affiliates, or (b) in the research and development, 
marketing and sale of technologies for utilizing limestone or lime. The former
restrictions will apply anywhere the Company is or is then contemplating doing 
business and the latter restrictions will apply throughout the world. You agree
to notify the Company of any employment you take during that two year period and
you agree that if you breach this paragraph, the Company can seek an injunction
to prevent you from working at that job, cease the payment of any compensation 
and benefits under paragraph 1 and sue you for damages. During this two year 
period, you also agree not to solicit for hire any employees of the Company or 
its subsidiaries.

5. Definitions. For purposes of this letter, you may be 
terminated for "cause" only if the Board (nonemployee directors only) 
unanimously determines that you have (i) deliberately and intentionally engaged 
in gross misconduct that is intentionally and demonstrably harmful to the 
Company, or (ii) you have been convicted of a felony. Further, for purposes of 
this letter, you will be deemed to have been terminated by the Company without 
cause if you terminate your employment a reasonable time after and because (i) 
the Company takes action which results in a material and continuing diminution 
in your status as an officer of the Company, (ii) the Company requires you to 
relocate your office more than 30 miles, or (iii) the Company reduces your 
overall level of compensation (other than as part of a reduction applicable to 
all salaried employees of the Company generally), or (iv) a company that 
acquires the Company by merger, acquisition of assets or otherwise does not 
expressly assume the Company's obligations under this letter agreement at or 
prior to the closing of the transaction.

6.	Disputes.  Disputes under this letter agreement (other than the 
Company's enforcement of paragraph 4 in equity) will be resolved by 
submitting the matter to binding arbitration in accordance with the 
Commercial Arbitration Rules of the American Arbitration Association in 
Pittsburgh, Pennsylvania. If you are required to bring or defend an action 
against the Company under this Agreement, the Company will pay your 
reasonable legal fees if you are successful. Before the Company is 
required to pay you any amounts under this letter agreement, the Company 
may require you to execute a reasonable release of any claims you may 
have against the Company (other than under this letter agreement).

7.	Taxes.  You will be responsible for the payment of all taxes on any 
payments you receive under  this letter  agreement, provided, that the Company 
will make you whole for taxes under Section 4999  of The Internal Revenue 
Code, or any  successor provision, if any.

8. Summary. A summary of the compensation and benefits 
that are intended to be paid or 
provided to you under this letter agreement (which replaces the Change of 
Control Agreement to which you are currently a party) and under the Company's 
other benefit plans in certain circumstances is attached as Exhibit B.

                                    10-2

The Company intends to be legally bound by this letter agreement. If 
you agree with the terms of this letter and intend to be legally bound by it,  
please sign  this letter where indicated below and return it to me. The
additional enclosed copy of this letter is for your files.

Thank you for your continued service to Dravo.

Very truly yours,

DRAVO CORPORATION
