                               PART I

Item 1.   BUSINESS
          --------  
Michael Baker Corporation ("Baker" or "the Registrant") was founded in 1940 and
organized as a Pennsylvania corporation in 1946.  Today, through its operating
subsidiaries and joint ventures, Baker provides engineering, construction, and
operations and technical services worldwide.  The Registrant is organized into
the following five market-focused business unit segments:  Buildings, Civil,
Energy, Environmental and Transportation.

Information regarding the amounts of revenue, operating profit and identifiable
assets attributable to the Registrant's industry segments is contained in 
Note 3 to the consolidated financial statements, which are included within 
Exhibit 13.1 to this Form 10-K.  Such information is incorporated herein by 
reference.  

According to the annual listings published in 1997 by ENGINEERING NEWS RECORD
magazine, Baker ranked 40th among U.S. design firms, 15th among transportation
design firms, 41st among international design firms, 153rd among U.S.
construction contractors and 94th among construction management for-fee firms. 
These rankings were based on 1996 revenues.

         BUSINESS UNITS
         --------------
BUILDINGS.  The Buildings unit comprises a general construction, construction
management and design-build division and a facility planning and design
division, that together pursue the growing design-build market.  This unit
offers a variety of services including design-build, construction management,
planning, program management, general contracting, architectural and interior
design, construction inspection, and constructability reviews.  The Buildings
unit has completed a wide range of projects, such as corporate headquarters,
data centers, hospitals, correctional facilities, educational facilities,
airports and entertainment facilities. 

CIVIL.   The Civil unit comprises the Registrant's civil engineering and water
resources division and its military operations and maintenance service 
division, Baker Support Services, Inc. ("BSSI").  This unit has combined 
Baker's military infrastructure work in planning and operations & maintenance, 
to improve its ability to market to, and serve, the U.S. Department of Defense,
a significant Baker client.  Though this unit is Baker's most diverse unit, its
focus is on core competencies such as surveying, mapping, geographic 
information systems ("GIS"), planning, design, construction management and
total program management.  The Civil unit serves clients in the fields of 
telecommunications, water resources, pipelines, resources management, water/
wastewater systems and facilities operations and maintenance.

ENERGY.   The Energy unit comprises Baker/MO Services, Inc. ("Baker/MO") and
Baker/OTS, Inc. ("Baker/OTS").  This unit focuses on providing comprehensive
operations, maintenance and technical services to energy industry clients
worldwide.  Baker/MO provides specialized services to the oil and gas, utility,
and petrochemical industries, while Baker/OTS provides operations and technical
services to major international oil and gas producers, principally outside the
United States.  Services provided by the Energy unit include turbine overhauls,
mechanical services including major equipment outages, operations and
maintenance, in-shop and onsite mechanical reconditioning, and training 
services for energy producers.

ENVIRONMENTAL.   The Environmental unit provides a combination of engineering
and consulting services in both the public and private markets.  Some recent
projects include air permitting of manufacturing facilities, bioremediation of
petroleum contaminated soils, evaluation and redevelopment of brownfield sites,
performance of the U.S. Navy CLEAN program, use of GIS to track the spread of
contaminants at industrial sites, and compliance programs for oil and gas
production platforms in the Gulf of Mexico.

TRANSPORTATION.   The Transportation unit combines engineering capabilities in
highways, bridges, transit, aviation and rail, with heavy and highway
construction capabilities, in its two divisions.  The services provided by this
unit have enhanced the Registrant's existing capabilities to serve
transportation clients. This unit has a national reputation for outstanding
planning, design, construction, program management and software development
capabilities in highways, bridges, airports, busways and other transit
facilities.

              DOMESTIC AND FOREIGN OPERATIONS
              -------------------------------
Approximately 90% and 88% of the Registrant's total contract revenues were
derived from work performed within the United States for the years ended
December 31, 1997 and 1996, respectively.  Of those domestic-based revenues, 
the majority comprises engineering and construction work performed in the 
Northeast region of the U.S.  The Registrant's international-based revenues are
derived primarily from Baker/OTS and relate to operations and technical 
services performed outside the U.S.  Baker/OTS provides the majority of its
services in the Middle East and Africa.

              FUNDED AND UNFUNDED BACKLOG
              ---------------------------
The Registrant's funded backlog, which comprises that portion of uncompleted
work represented by signed contracts and for which the procuring agency has
appropriated and allocated the funds to pay for the work, was $393 million at
December 31, 1997 and $333 million at December 31, 1996.  Total backlog, which
incrementally includes that portion of contract value for which options are
still to be exercised (unfunded backlog), was $649 million at December 31, 1997
and $544 million at December 31, 1996.

There is not necessarily a direct correlation between the foregoing figures and
the Registrant's annual total contract revenues.  In the case of multi-year
contracts, total contract revenues are spread over several years and correspond
to the timing of the contract rather than the Registrant's fiscal year.  Many
multi-year contracts, particularly with agencies of the U.S. government, 
provide for optional renewals on the part of the customer.  The Registrant's 
experience has been that these optional contract renewals have generally been 
exercised.  Funded backlog generally is highest during the last quarter of each
of the Registrant's fiscal years because that corresponds to the first quarter 
of the U.S. government's fiscal year, which is when many government contract 
renewals occur.  

              CUSTOMERS
              ---------
No individual contract accounted for more than 10% of the Registrant's total
contract revenues in 1997, 1996 or 1995; however, several contracts with the
U.S. Department of Navy and the State of Illinois provided 10.9% and 10.5%,
respectively, of the Registrant's total contract revenues in 1995.
<PAGE>
          COMPETITIVE CONDITIONS
          ----------------------
The Registrant's business is highly competitive with respect to all principal
services it offers.  Baker competes with numerous firms which provide some or
all of the services provided by the Registrant.  The competitive conditions in
the Registrant's businesses relate to the nature of the contracts being 
pursued.  Public-sector contracts, consisting mostly of contracts with federal 
and state governmental entities, are generally awarded through a competitive 
bidding process, subject to the contractors' qualifications and experience.  
The Baker business units employ extensive cost estimating, scheduling and other
computerized techniques for the preparation of these competitive bids.  
Private-sector contractors compete on the bases of qualifications, quality of
performance, price of services and other related factors.  Such private-sector
contracts are generally awarded on a negotiated basis.

The Registrant believes that the principal competitive factors (in various
orders of importance) in the areas of services it offers are quality of 
service, reputation, experience, technical proficiency and cost of service.  
The Registrant believes that it is well positioned to compete effectively by
emphasizing its full range of professional services.

          SEASONALITY
          -----------
Based upon the Registrant's experience, total contract revenues and net income
from engineering and construction-related services tend to be lower for the
first quarter than for the remaining quarters due to winter weather conditions,
particularly for projects in the Northeast and Midwest regions of the United
States.

          PERSONNEL
          ---------
At December 31, 1997, the Registrant employed approximately 3,670 persons,
broken down by business unit as follows:

     Buildings unit--250               Environmental unit--160
     Civil unit--1,630                 Transportation unit--780
     Energy unit--820                  Corporate staff--30

The Registrant's employees are not represented by labor unions, with the
exception of its construction personnel which are generally covered by
collective bargaining agreements, as are certain BSSI employees in the Civil
unit.  Currently, the Registrant considers its relationships with labor unions
to be good.

Coraopolis and New Brighton, Pennsylvania.

Item 3.    LEGAL PROCEEDINGS
           -----------------
The Registrant has been named as a defendant or co-defendant in legal
proceedings wherein substantial damages are claimed.  Such proceedings are not
uncommon to the Registrant's business.  After consultations with counsel,
management believes that the Registrant has recognized adequate provisions for
these proceedings and their ultimate resolutions will not have a material
adverse effect on the consolidated financial position or annual results of
operations of the Registrant. 

The only significant proceeding relates to a lawsuit brought in 1987 in the
Supreme Court of the State of New York, Bronx County, by the Dormitory 
Authority of the State of New York against a number of parties, including the 
Registrant and one of its wholly-owned subsidiaries, that asserts breach of 
contract and alleges damages of $13 million.  The Registrant, which was not a 
party to the contract underlying the lawsuit, contends that there is no 
jurisdiction with respect to the Registrant and that it cannot be held liable 
for any conduct of the subsidiary.  Both the Registrant and the subsidiary are 
contesting liability issues and have filed cross-claims and third-party claims 
against the other entities involved in the project.  

Item 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
          ---------------------------------------------------
No matters were submitted to a vote of the Registrant's security holders during
the fourth quarter of 1997.
