UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

  The following unaudited pro forma combined financial information is derived
from the historical consolidated balance sheets and related consolidated
statements of Dames & Moore's and URS' operations adjusted to give effect to
the Dames & Moore acquisition and URS' plan for financing the acquisition of
Dames & Moore (the "Financing Plan"). References to the "Combined Company" refer
to URS and Dames & Moore after giving effect to the Dames & Moore acquisition.
In addition, the Dames & Moore financial information has been adjusted to give
effect to the acquisition of Radian International ("Radian") as of January 1,
1998. The unaudited pro forma combined balance sheet may not reflect the
Combined Company's actual financial position as of April 30, 1999. The unaudited
pro forma combined statements of operations may not reflect the actual results
of operations the Combined Company would have had for the six months ended
April 30, 1999 or the twelve months ended October 31, 1998. The unaudited pro
forma combined financial statements also do not reflect the future financial
position or results of operations for the Combined Company.

  The unaudited pro forma combined balance sheet and statements of operations
are provided for illustrative purposes only and should be read in conjunction
with the accompanying notes.

  URS has assumed for purposes of the unaudited pro forma combined balance
sheet as of April 30, 1999 that the Dames & Moore acquisition and the
Financing Plan occurred as of that date. URS has assumed for purposes of the
unaudited pro forma combined statements of operations for the six months ended
April 30, 1999 and the twelve months ended October 31, 1998 that the
Dames & Moore acquisition and the Financing Plan occurred as of November 1,
1997. URS' fiscal year ends on October 31 and Dames & Moore's fiscal year ends
on the last Friday of March. To present comparable data for Dames & Moore and
URS, the pro forma statements of operations include the historical data for
Dames & Moore for the six months ended March 26, 1999 and for the twelve
months ended December 25, 1998. Therefore, the results of operations for Dames
& Moore for the period September 26, 1998 through December 25, 1998 are
reflected both for the six months ended March 26, 1999 and for the twelve
months ended December 25, 1998. The total revenues and net earnings of Dames &
Moore for the three months ended December 25, 1998 that have been reflected in
both periods are approximately $287.4 million and $5.3 million, respectively.

  NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENTS OF OPERATIONS--(CONTINUED)
                            (dollars in thousands)

     In connection with the RCBA Equity Investment, we will issue 46,083 shares
     of Series A Preferred Stock and 450,000 shares of Series C Preferred Stock.
     The Series A Preferred Stock carries a cumulative paid-in-kind dividend
     rate of 8% for the first six months after its issuance and 15% thereafter.
     If stockholder approval of the issuance of the Series B Exchangeable
     Convertible Preferred Stock is not obtained within six months after the
     issuance of the Series A Preferred Stock, the dividend rate for the Series
     A Preferred Stock will be recalculated and paid as if the dividend rate was
     15% from its issuance. However, we anticipate that the Series A Preferred
     Stock together with the Series C Preferred Stock will be exchanged for
     newly issued Series B Exchangeable Convertible Preferred Stock, subject to
     stockholders' approval. The Series B Exchangeable Convertible Preferred
     Stock will be convertible, voting preferred with a cumulative paid-in-kind
     dividend rate of 8%.

     The annual Series A Preferred Stock paid-in-kind dividend of $15,000 has
     been reflected in the pro forma income statements as a reduction in income
     available to common stockholders.

     The Series C Preferred Stock does not pay a current dividend; however,
     because it is mandatorily redeemable in six years, its value results in an
     accretive charge of $4,000 annually.

(e)  Reflects reversal of non-recurring acquisition-related restructuring costs
     and other charges included in Dames & Moore's historical results of
     operations.
