SUBJECT: FOOTHILL BRIDGE REPLACEMENT PROJECT, SPECIFICATION
NO, 90197D CONSTRUCTION MANAGEMENT AMENDMENT
CAO RECOMMENDATION
Approve Amendment No. 9 to the Construction Management Services Agreement with MRO
Engineers and authorize the Mayor to execute the Amendment.
DISCUSSION
The replacement of the Foothill Bridge is largely complete after a year and a half of construction.
From the beginning, the project has required consultant services for construction. Inspection and
environmental monitoring were required on a full time basis and since the City does not have a
bridge inspector or a biologist to dedicate full-time to the project, this service has been provided
by the designers MRO Engineers. The project budget included funding for these needs at the
time of award.
As the project neared completion, it became clear that additional funds would be required to
provide the remaining inspection and monitoring services required. The key reason for this is
that the project construction timeline changed from that originally envisioned. This occurred
primarily for two reasons, each of which added over a month to the project. The first was the
conversion of the project to allow the bridge to be built over the existing culverts. This extended
the duration of the project but allowed the bridge to be completely open to traffic several months
sooner. The second was the discovery of contaminated water and extended unstable backfill in
the excavation. These conditions were unknown to the City at the time of award and also caused
delays to the construction timeline.
On December 6, 2005, the City Council authorized $50,000 for additional construction
management and monitoring services. Through an oversight Amendment No. 9 to the
Agreement with MRO Engineers was not included with the request for funding. Staff is now
requesting that Council authorize the amendment to allow Finance to process the final bills.

Foothill Bridge Construction Management Amendment Page 2
The bills associated with Amendment No. 9 represent approximately $30,000 of the total
$50,000 requested in December. At the time of the budget augmentation request, the extent of
the additional cost was not known. At this time, staff has all but a minor bill outstanding and is
able to provide a much better estimate as to the final additional cost needed to complete the
construction management and environmental monitoring. Of the $20,000 that appears will be
remaining in the account at completion, only $4,000 are actually City funds with the remainder
being grant funds.
