City Council Meeting: September 11, 2001 Santa Monica, California
TO: Mayor and City Council
FROM: City Staff
SUBJECT:Authorize the City Manager to Increase the Contingency to Contract 7519
(CCS) with Pacific Mechanical Corporation for the Moss Avenue Pumping
Station, Phase 2 Project
Introduction
This report recommends that the City Council approve an increase in the contingency for
Contract 7519 (CCS) in the amount of $58,554.14 for the construction of the Moss Avenue
Pumping Station, Phase 2.
Background
The Coastal Interceptor Sewer (CIS) collects sewage from the City of Los Angeles north of
the City limits and, with additional flows from the City of Santa Monica, carries it to the City
of Los Angeles? Hyperion Plant for treatment. The 1994 Northridge earthquake damaged
many sections of the CIS and projects are underway to repair the damage. The cities of
Santa Monica and Los Angeles are working jointly on this rehabilitation effort, with Santa
Monica serving as the lead agency for that portion of the CIS within the City of Santa
Monica. The entire CIS project includes the Pacific Coast Highway sewer replacement, the
Ocean Avenue and Neilson Way relief sewer and the Moss Avenue pumping station.
Construction has been completed for Phases 1 and 2 of the Moss Avenue pumping station,
1
the Appian Way project and Phases 1A and 1B of the Pacific Coast Highway sewer
replacement project. Construction for the Ocean Avenue/Neilson Way relief sewer, Phase
2 of the Pacific Coast Highway sewer replacement and Phase 3 of the Moss Avenue
pumping station projects are currently underway.
Discussion
On July 13, 1999, City Council awarded a construction contract to Pacific Mechanical
Corporation in the amount of $2,546,000 and approved a construction contingency of
$350,000 for the construction of Phase 2 of the Moss Avenue Pumping Station.
During the course of construction an additional pump was added at the request of the City
of Los Angeles to accommodate future flows. The cost of this addition to the contract was
$228,866.83, leaving $121,133.17 remaining in the project contingency for completion of
construction. Other essential changes have lowered the project contingency to
$29,530.82. Negotiations over project closeout items resulted in a final amount of
$88,084.96. Thus, $58,554.14 must be added to the project contingency in order to pay
Pacific Mechanical Corporation for work performed.
Budget/Financial Impact
Funds in the amount of $58,554.14 are available in Account C31034500.589000, ?Moss
Avenue Pumping Station?. The City of Los Angeles reimburses the City of Santa Monica
100 percent of the wastewater costs of the Moss Avenue Pumping Station project, which
2
will be recorded in revenue account 31661.400890 in FY 2001-02. In turn, the City of Los
Angeles bills Santa Monica?s share (which is approximately two percent of the cost) in the
annual invoice for Hyperion capital costs.
Recommendation
Staff recommends that the City Council:
1. Approve an increase in the contingency to Contract 7519 (CCS) with Pacific
Mechanical Corporation in the amount of $58,554.14; and
2. Authorize the City Engineer to issue any necessary change orders to complete
additional work in conformance with the Administrative Instructions on change
orders.
