Exhibit 99.1

    BAKER FILES 2005 FORM 10-K; RESTATES FINANCIAL RESULTS FOR 2003 AND 2004

PITTSBURGH, Aug. 15 /PRNewswire-FirstCall/ -- Michael Baker Corporation (Amex:
BKR) today announced the filing of its Annual Report on Form 10-K for the fiscal
year ended December 31, 2005, which includes the restatement of the company's
consolidated financial statements for the years ended December 31, 2004 and
2003. As outlined in the filing with the Securities and Exchange Commission,
Baker has restated its 2003 and 2004 financial statements as a result of the
company's identification of various tax accounting, non-routine accounting and
transaction errors, and describes in detail, in Footnote 2 of the Consolidated
Financial Statements included in Exhibit 13.1, the impact of the restatement on
the net income/(loss) and diluted earnings/(loss) per share for the two restated
periods. The complete copy of the Form 10-K can be found on the Investor
Relations portion of Baker's website at www.mbakercorp.com.

For 2005, the company reported net income of $5.1 million, or $0.58 per diluted
common share, on total contract revenues of $579 million, compared to restated
net income of $8.4 million, or $0.98 per diluted common share, on total contract
revenues of $552 million in 2004. For 2003, the company reported a restated net
loss of $0.8 million, or $0.10 per diluted common share, on total contact
revenues of $427 million. Income from operations in 2005 was $16.9 million,
compared to restated income from operations of $18.9 million and $5.7 million in
2004 and 2003, respectively.

The company's Engineering business segment's total contract revenues in 2005
were $371 million, compared to restated total contract revenues of $343 million
in 2004 and $251 million in 2003. The company's Energy business segment's total
contract revenues in 2005 were $208 million, compared to restated total contract
revenues of $209 million in 2004 and $176 million in 2003.

Operating income before corporate overhead allocations in the Engineering
segment for 2005 was $40.2 million, an increase of 21 percent compared to the
restated operating income before corporate overhead allocations for 2004. The
operating loss before corporate overhead in the Energy business for 2005 was
$0.9 million, a substantial decrease from the restated operating income before
corporate overhead allocations for 2004.

Total backlog for the Engineering and Energy businesses at year-end 2005 was
$1.32 billion, compared to $1.40 billion at year-end 2004. The year-over-year
decrease is attributable primarily to the work completed during the year on the
company's flood map modernization contract with FEMA. At December 31, 2005, $566
million of backlog related to this contract, compared to $678 million at
December 31, 2004.

Outlook for 2006

"The restatement is behind us, so we can now place our complete focus on
continuing to grow and to improve the profitability of our business segments,"
Donald P. Fusilli, Jr., president and chief executive officer, said. "The key
markets for our services are strong, and we expect them to remain so for the
foreseeable future. In the Engineering segment, recent contract awards with FEMA
and US-VISIT reflect a continued growth in Federal government spending in our
key target areas, and we are beginning to see increased activity for
transportation infrastructure projects resulting from the new SAFETEA-LU
legislation. In our Energy segment, our recent Managed Services contract awards
in Alabama and Alaska represent an increased demand for our higher margin,
comprehensive operations and maintenance services. Our challenge going forward
will be to further align our engineering and operations and maintenance services
with our clients' needs in the targeted markets that we serve."
