STAFF REPORT
As a part of the project, the Contractor is constructing the bridge
over Warm Creek. During construction of the abutment walls, the resident
bridge engineer noted that the plans did not call for the installation of
water stops between the abutment walls and the wing walls. The waterstop is
to prevent water seepage into the backfill and to provide for more integrity
of the fill slopes. After conferring with both Caltrans and the Contractor,
it was decided that it should be installed. Contract Change Order No.1 is
an increase in the contract price of $632.10 (not to exceed) from $553.304.00
to $553,936.10. This additional work and the change order have been reviewed
and approved by Caltrans.
At the pre-construction meeting for this project, Edison Company
noted that the plans called for a stack type of dual power meter pedestal to
be installed. Current City and Edison Company practice calls for the use of
side by side meter installations. One of the meters is for the traffic signal
while the other is used for the street lights. Two meters are necessary be-
cause of different billing rates and methods. The Contractor has prepared
an estimate for supplying the side by side meter pedestal in lieu of the stack
type and performing the necessary work for the proper installation. The esti-
mated additional work and materials amounts to $345.00, from $553,936.10 to
$554,281.10. Contract Change Order No.2 is required to meet current standards
and has been agreed to by Caltrans.
During construction of the wing walls at the easterly end of the
abutment walls, the existing channel slopes were found to contain rubble and
mixed construction materials (old tile, wire lath and plaster, broken concrete,
etc.) which were unsuitable for either footing trench or backfill. The Resi-
dent Engineer directed the removal of the unsuitable material and this over-
excavation required the construction of wing walls that were taller than called
for on the plans. This additional construction required additional steel and
concrete to fill the void left by the removal of unsuitable materials. The
total cost for the removal and disposal of unsuitable materials, installation
of additional steel and concrete in the wing walls and all associated work, is
$1,359.00, bringing contract price from $554,281.10 to $555,640.10.
Funds for the change orders are contained in the contingencies for the
project and Caltrans has reviewed and approved all of the necessary changes,
thereby making them part of the project funding.
Staff recommends that Change Order Nos. 1, 2 and 3 be approved.
