council Meeting: July 25, 1995 Santa Monica, California
TO: Mayor and city Council
FROM: City staff
SUBJECT: Award of Contract for Sewer Main Improvements, and Sewer
Main and Storm Drain Relining at Various City Locations
Introduction
This report recommends that the City Council award a contract for
sewer main improvements, and sewer main and storm drain relining
for FY 1994-95, at various City locations to Insituform Southwest,
the lowest responsible bidder, in the amount of $1,738,108.
Background
During the FY 1994-95 budget process, city Council appropriated
funds for sewer main improvements, and sewer main and storm drain
relining at various locations in the city.
The sewer main improvements will replace and upgrade sewer mains
which are under capacity, have deteriorated due to age, and/or are
corroded and cracked. The proposed locations were recommended for
replacement by the city's Sanitary Sewer Master Plan (prepared by
CH2M Hill in 1992) , and confirmed by the city's Wastewater
Division.
The sewer main relining work will take place in areas where the
sewer mains are inaccessible to equipment necessary for open trench

operations (such as narrow alleys and rear yard easements on
private property); where mains are severely deteriorated due to age
and corrosion; and where replacement is not needed for additional
sewer capacity. The storm drain relining work will also take place
in the connector pipes, from existing catch basins to the County
Flood Control Channels, where replacement is not necessary but the
pipes are badly deteriorated due to age and corrosion. The
relining work consists of inserting a pipe lining system into
existing sewer pipe lines resulting in improved flow, eliminated
pipeline obstruction, and prolonged service life of the mains.
A Notice Inviting Bids was published on June 12 and June 13, 1995
in The Outlook, as well as in four construction journals. In
addition, bidding documents were sent to six woman/minority
business enterprise associations (WMBE) . Bidding packages were
requested by 10 contractors. The city Clerk's office received two

27, 1995 by the Deputy City Clerk.
