Item 6-D
Council Meeting: 3/25/97 Santa Monica, CA
TO: Mayor and City Council
FROM: City Staff
SUBJECT: Award of Contract for Rehabilitation and Repair of
Sewer Mains at Lincoln and 11th Courts between Georgina
and Colorado Avenue
Introduction
This report recommends that the City Council award a contract for
rehabilitation and repair of sewer mains at Lincoln and 11th
Courts between Georgina Avenue and Colorado Avenue to Insituform
Southwest, the lowest responsible bidder, in the amount of
$1,521,545.
Background
During the January 17, 1994 earthquake, many of the City's sewer
mains were damaged. The City initiated an inspection program of
the sewer mains in order to determine the extent of damage to the
sewer system. The locations indicating earthquake damaged sewer
lines were submitted to Federal Emergency Management
Agency/Office of Emergency Services (FEMA/OES) for funding
approval for the repair work. This is the first earthquake
damage sewer line repair project to be undertaken using FEMA/OES
funding. The Damage Survey Report (DSR) for the proposed work
at Lincoln and 11th Courts was approved by FEMA/OES. At the
same time this work is being accomplished, the City will
rehabilitate maintenance access holes which are part of the
City's annual sewer maintenance program and funded separately by
the City's sewer main improvement fund.
The sewer repairs involve relining the sewer mains which have
cracked or separated due to the earthquake. The proposed
locations were prioritized and scheduled for repairs based on the
severity of the damage. The relining work consists of inserting
a pipe lining system into existing sewer pipe lines which
improves flow, eliminates pipeline obstruction, seals cracks,
and prolongs service life of the mains. This trenchless approach
to sewer line repairs poses minimal disruption to traffic
compared to conventional construction for sewer replacement.
A Notice Inviting Bids was published on December 5 and December
6, 1996 in The Outlook, as well as in four construction
journals. In addition, bidding documents were sent to six (6)
women/minority-owned business enterprise associations (WMBE).
Bidding packages were requested by seven (7) contractors. The
City Clerk's office received three (3) sealed bids, which were
publicly opened and read aloud on January 6, 1997 by the Deputy
City Clerk.
The base bid results were as follows:
1. Insituform Southwest $1,521,545.00
2. Sancon Engineering, Inc $1,585,157.50
3. U-Liner West $1,592,287.50
City Engineer's Estimate $1,600,000.00
The low bidder, Insituform Southwest, supplied the City with
references and all references reported that the Contractor's work
was satisfactory. The State Contractor's License Board verified
that the Contractor's license is current, active and in good
standing.

To finance the 10% amount during the interim, $148,515 is to be
appropriated in a new CIP account, 31-760-661-20097-8905-99124
