II. PROCEDURES

     A.  At the beginning of each fiscal year, the CEO of PWR will approve the
         Participants to be included in the Plan and the applicable Maximum
         Bonus percentage for each Participant.  He also will determine their
         applicable Business Units for purposes of applying this Plan.  Upon
         approval by the CEO of PWR, additional Participants may be added during
         the year on a pro-rata basis, but no additions may be made during the
         final five months of the fiscal year.

     B.  As soon as practicable after release of the annual earnings of  PWR to
         the public and in no event later than May 31st, calculations of the
         actual bonus amounts due to each Participant shall be made and bonuses
         paid in cash.

     C.  Only those Participants who are employed by the Company on the last day
         of the fiscal year shall be eligible to receive a bonus.  In addition,
         any Participants who voluntarily resign from the Company prior to the
         annual earnings announcement shall forfeit any bonus.

     D.  Any discretionary bonuses for Participants with responsibility for a
         specific Business Unit(s) will be determined based upon the discretion
         of the CEO of  PWR, subject to approval by the Committee.  The CEO of
         PWR will recommend any discretionary bonuses for Participants with
         Corporate responsibilities, subject to approval by the Committee.  The
         Committee will determine if the CEO and any other officers of  PWR who
         are subject to Section 16 of the Securities Act are entitled to any
         discretionary bonus.

         for the remainder of the year and added to the existing Budget of the
         Business Unit having ongoing responsibility for such acquisition.
         Comparisons to prior years amounts will be based as close as
         practicable on pro-forma prior year results of the acquired entity,

     F.  Administration of this Plan, consistent with its terms, has been
         delegated to the CEO of  PWR by the Committee, which retains the right
         to decide all matters of interpretation and decision(s) of the
         Committee shall be final and binding.  The Committee also retains the
         right to change, prospectively or retroactively, any and all terms of
         this Plan by a majority vote of its members.
