ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     On September 8, 2005, Eric Nielsen, President and Chief Operating Officer
of The Keith Companies, Inc., a California corporation (the "COMPANY") entered
into a Letter Agreement, dated as of August 29, 2005 (the "LETTER AGREEMENT")
with Stantec Consulting, Inc. ("STANTEC"). The Letter Agreement provides that
upon consummation of the previously announced merger between the Company and a
wholly-owned subsidiary of Stantec, the Change of Control Letter Agreement,
dated March 22, 2001, by and between Mr. Nielsen and the Company (the "CHANGE OF
CONTROL AGREEMENT"), shall be assumed by Stantec and will continue to apply to
any termination of Mr. Nielsen's employment within two years of the merger. The
Letter Agreement also provides that upon consummation of the merger Mr. Nielsen
will serve as the regional leader for Stantec's operations in the southwest
United States. Mr. Nielsen confirmed in the Letter Agreement that such
post-merger change in title and job responsibilities will not constitute a
constructive termination under his Change of Control Agreement. Pursuant to the
Letter Agreement, Mr. Nielsen's salary and discretionary bonus for the two year
period following the merger will be at least $450,000 annually.

     The foregoing description of the Letter Agreement does not purport to be
complete and is qualified in its entirety by reference to the Letter Agreement,
which is filed as Exhibit 10.1, and is incorporated herein by reference.
