AGENDA TITLE: Amend Agreement to Provide Construction Engineering Services for Water Storage
Tank Construction, 1215 Thurman Street ($23,500)
MEETING DATE: July 2, 1997
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council authorize the City Manager to amend the upper limit
of the professional services contract with Montgomery Watson Engineers
for construction engineering services from $64,042.00 to $90,600.00 and
authorize the transfer of funds in the amount of $70,000.00 from the
completed Well 4 Construction project into the Water Tank Construction account to cover overruns and
this addition to the engineering contract.
BACKGROUND INFORMATION: The original estimate of costs for contract engineering services for
the water storage tank was based on Montgomery Watson's
estimate of the work involved in reviewing contractor submittals,
responding to requests for information and clarification, and contract
change orders. The time involved in reviewing submittals is dependent upon their completeness and
complexity of the information supplied by the construction contractor. Some of the larger submittals had
to be resubmitted and reviewed several times. Listed below are the estimated and actual number of
submittals, requests for information and change orders.

Clearly, more of each estimated task was performed by the consultant than previously estimated and
there is still the facility start-up assistance to be completed.
*There were a total of 104 submittals made on this project; 36 of them were reviewed and approved by
City engineering staff, 68 were reviewed by Montgomery Watson.
**Some of the work completed by Montgomery Watson under the construction engineering services
contract was work the staff felt Montgomery Watson should have completed under the earlier design
contract, specifically the costs incurred in processing some of the change orders. To that end, we
negotiated the $12,195.00 deduction in costs from this contract, as shown on the cost breakdown.
