ITEM 6-M
Council Meeting: August 9, 1994 Santa Monica, California
TO: Mayor and City Council
FROM: City Staff
SUBJECT: Award of Contract for Storm Drain Improvements,
Sanitary Sewer Main Replacements, Sanitary Sewer Main
Relining and Water Main Replacements at Various City
Locations
Introduction
This report recommends that the City Council award a contract for
storm drain improvements, sanitary sewer main replacements,
sanitary sewer main relining and water main replacements at
various City locations to Colich & Sons, the lowest responsible
bidder, in the amount of $1,788,401.31.
Background
During the FY 1992-93 and 1993-94 budget process, the City
Council appropriated funds for storm drain improvements, sanitary
sewer main replacements, sanitary sewer main relining and water
main replacements at various locations in the City.
The storm drain improvements will replace the existing limited
capacity drywells (holes in the ground covered by metal grates)
located in alleys throughout the City with larger concrete catch
basins which connect directly into the Los Angeles County storm
drain. Thus, water ponding in alleys and the costs of processing
water which overflows into alley sewer drains will be alleviated.
The sanitary sewer main replacements will replace sanitary sewer
mains which have deteriorated due to age, 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 sanitary sewer main relining work will take place in areas
where the wastewater lines are inaccessible for equipment
necessary for open trench operations (such as narrow alleys and
rear yard easements on private property), where lines are
severely deteriorated due to age and corrosion, and where
replacement is not needed since it does not require additional
sanitary sewer capacity. Relining consists of inserting a pipe
lining system into an existing wastewater line which results in
improved flow, fewer sewer back-ups and prolonged service life of
the lines. The water main replacement will upgrade the existing
system to improve water pressure in the area and provide better
fire flows in the area.
A Notice Inviting Bids was published on June 27 and June 28,
1994, in The Outlook, as well as in four construction journals.
In addition, bidding documents were sent to six women/minority
business enterprise associations (WMBE). Bidding packages were
