6.1. K. - Page 1 RE PO RT To the Honorable Mayor and City Council From the City Manager August 22, 2011 SUBJECT Award of Contract — Sanitary Sewer and Water Replacement Project (Redwood Avenue, Norman Court, and Ebener Street) RECOMMENDATION Approve, by motion, the contract documents and award the standard form contract for the Sanitary Sewer and Water Replacement Project (Redwood Avenue, Norman Court, and Ebener Street) to Casey Construction, Inc. of Redwood City for their responsive and responsible low bid of $1,088,974.00 and authorize the City Manager to increase the contract amount, if necessary, up to 10% of the amount awarded, not to exceed $1,197,871. BACKGROUND The city systematically replaces sections of aging sewer and water infrastructure to ensure the continued reliability of the system. Each year, staff from Engineering and Public Works Services departments identifies pipelines that required excessive maintenance or experienced repeated service disruptions and target those pipelines for improvement. The city completed closed circuit television (CCTV) inspection of Sanitary Sewer Basin No. 8 in 2010. Staff reviewed the inspection videos and assessed the condition of the pipelines. Replacement of the sanitary sewer along Redwood Avenue and Norman Court was expedited due to numerous defects such as cracks and offset joints. Sanitary sewer and watermain projects will be performed concurrently at Norman Court as both systems at this location require replacement. Staff inerges sewer and water projects whenever possible to minimize disruption to neighborhoods. Completion of the sanitary sewer replacement will improve the condition and capacity of the collection system. This project will replace approximately 735 linear feet of 6-inch vitrified clay pipe (VCP) sewer main with new 8-inch polyvinyl chloride pipe (PVC), 4,210 linear feet of 8-inch VCP sewer main with new 10-inch PVC. Additionally, 375 linear feet of 2-inch water main along Norman Court will be replaced with 8-inch PVC. Twelve (12) bids were received at the bid opening on July 6, 2011 and are summarized below.
