SR-6M (10) EPWM:CP:LR:gs/CC1383.1 (S:\SP1383) Council Meeting: August 9, 1994 6 M Santa Monica, California AUG 0 9 1994 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 Replacenents 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 respons~ble 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 w~ll 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. - 1 - AUG 0 9 1991t 6 M I 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 inaccesslble 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 serVlce 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 assoclations (WMBE). Bidding packages were requested by 25 contractors.
