June 22, 24�9 SUBJECT Award of Contract -- EI Camino Real Sewer and Wa#er Main Replacement Project (Lincoln Avenue to Roosevelt Avenue} REC4MMENDATIQN Appro�e, by motion, the can#rac# documents and award the contract for the EI Camino Real Sewer and Water Main Replacement Project (Lincoln Avenue to Roosevelt Avenue) to #he lowes� responsibie bidder, Casey Construction, lnc. of Emeraid Hills for their responsive and responsible Cow bid of$231,889.00 and authorize the Ci#y Manager to increase the contract amount up to 14% if necessary. BACKGR�UND The city systematically replaces sections of aging sewer infrastructure to ensure the cont�nued reliability of the system. Every year, Engineering and Construction staff and Public Works Services staff collective[y work to ident�y pipelines that have required excessive maintenance or have experienced repeated senrice disruptions. The sanitary sewer p�pefine between Lincoln Avenue and Roosevelt Avenue has required repeated repair by the city's Public Works Services staff. Closed circuit television (CCN) inspection has revealed numerous defects in this section of sanitary sewer pi�eline such as offset joints, sags and severe cracks. The ci#y's Engineering staff e�aluated a number of construction options for repair/replacement of this section including traditional open trench and trenchless techniques to determine the mosfi cast-�effective me#hod of m�igation. Alternative afignments that would have refocated the sanitary sewer trom the sidewalk to the street were evaluafed as well, however, were found nat feasible due to site constraints created by an exist�ng concrete box cul�ert which runs parailel to the sewer pipeline. Staff recommends using a traditional open trench method to replace the pipeline in the existing sidewalk location thereby requiring replacement of the sidewalk as well as the pipeline. Staff recommends replacemen#, at #he same time, of an existing and aging 2-inch galvanized water pipeline to avoid re-exca�ating the same general area in #he near future. The existing poorly performing water pipeline will be rep[aced with 8-inch PVC to increase the flow and pressure of water se�-vice in the neighborhoad, The proposed project wilf repface approximately 4�0 linear feet of sewer and water pipeline along El Camino Real befin►een Lincoln Avenue and RooseWe�Avenue. PG&E has installed electr'rcaf service on top of the city's sewer and water pipelines in th�s area which may campiicate the city's effotts to rep�ace the sewer and water pipelines. Engineering staff has coordinated the work of this pro�ect with PG&E and has requested the relocation of PG&E's electrica! facilities. As well, s�nce EI Camino Real is a state route, the city has secured the permit to work within fhe roadway as required by the state.
