Bas�d on their experience and qualifications, V&A was <br /> retained to develop the master plan. The plan includes a prioritized lis# of projects <br /> intended #o arrest naturally occurE-ing corrosion of the City's water transmission piping to <br /> extend �te useful life of the system. <br /> The Cathodic Prote�tian Project for Topaz and Redwood Shores Water Transmission <br /> Pipeiines was the first project recommended for comp�etion by #he master plan. V&A <br /> designed the project, the construction contract was awarded to Cvrrpro, and the projec# <br /> was successfully comple#ed in 2006. <br /> Cathodic protection for the water transmission pipelines along Seaport Bouie�ard is the <br /> second project recommended for completion by the master plan. The purpose of this <br /> project is to evaluate and improve the cathodic protection systems of finro Seaport <br /> Boulevard pipelines -- an 8-inch s#eel water distribution pipe ins#alled in 1937 and a 16- <br /> inch steel water transmissian pipe installed in 1978. Each pipeline is approximately <br /> 9,��0 fee# in length. <br /> The evaluation and design work of this project is proposed as follows. <br /> Phase I —"Assessment� <br /> Installation of ten new test stations, test, and anaiyze. <br /> Phase I! —"Design of Cathodic Protection System" <br /> Preparation of construction plans, estimates and specifications. <br /> Staff recommends V&A for the proposed assessment and design phases of the Seaport <br /> Boulevard � VIlater Transm�ssian Pipelines Cathodic Pratection Project due to their <br /> experience and past per�ormance on other similar City projec#s. <br />
