Dear Shareholder:

     In the recent Proxy Statement we sent to you, we asked for your support
for five Propositions which we believe are in the best interest of Dames & 
Moore and all its shareholders.  It's important that you return your proxy 
card indicating your support for these five Propositions.

     If your broker is holding your shares in "Street Name," please ask him 
to vote your shares affirmatively for each Proposition.

     Please call us if you have any questions regarding any of the 
Propositions.

                              Regards,


                              [SIG]
