Recommendation:
That City Council, by minute motion, approve:
1. Amendment No. 1 to Contract No. C22870C with Berg & Associates in
the amount of $133,050.00 for additional construction management
services for the Whitewater Bridge at Portola Avenue Project,
2. The transfer of $76,117.10 from contingency to base for this
amendment, and
3. The appropriation of $56,932.90 for this amendment from unobligated
funds in Account 400.
Background:
On July 14, 2005, City Council approved Contract No. C22870C with Berg & Associates for
construction management services in the amount of $761,171.00, plus a 10% contingency
for the Portola Bridge over the Whitewater Channel Project. Construction began on August
22, 2005. The project is approximately 70% complete and is scheduled to be entirely open
to traffic this July.
Discussion:
The construction management contract with Berg & Associates includes the required
inspection services, materials testing, and other direct costs. The original contract with
Berg & Associates was negotiated for a construction duration of 18 months. It is estimated
that the project will now take approximately 24 months to complete. Therefore, staff has
negotiated an Amendment No. 1 to Contract No. C22870C with Berg & Associates in the
mount of $133,050 to provide the construction management services required to complete
the project.

Staff has determined that the negotiated costs for the additional design services are
equitable and therefore recommends that City Council approve Amendment No. 1 to
Contract C22870C with Berg & Associates in the amount of $133,050.00 and authorize the
Mayor to execute the amendment. The revised total contract amount of $894,221.00 is
approximately 8.5% of the estimated construction cost, which is well within the acceptable
range for this project size and complexity. Staff also requests approval of the appropriation
of unobligated funds in the amount of $56,932.90 to Project Account 400-4359-433-4001
and to move $76,117.10 from contingency to base to fund this amendment.
