RECOMMENDATION: That the Board of Public Utilities approve the additional capital expenditure of$1,498,740 for Work Order No. 1111733,which includes all design and construction costs for the Streeter Avenue Railroad Grade Separation Water Pipeline Relocation Project (Phase 11). BACKGROUND: On September 27, 2012, the Public Works Department (Public Works) opened construction bids for the StreeterAvenue Railroad Grade Separation project(Project). The Projectwill entail lowering StreeterAvenue to create an underpass beneath the existing railroad tracks. The work will include modifying the surrounding roadways, as well as relocating various underground and overhead utilities. It is anticipated that the grade separation project will enhance safety and provide significant improvements to traffic flows along Streeter Avenue. During their regular meeting on February 3, 2012, the Board of Public Utilities authorized construction for Phase I of the Streeter Avenue Railroad Grade Separation water pipeline relocation work in an amount of $940,000. The first phase of the water pipeline relocation work involved installation of new water pipelines on the surrounding streets and has been completed recently by the water division field forces. This first phase of the work allowed a portion of the existing water distribution pipeline in Streeter Avenue to be abandoned, permitting PW's grade separation contractor to excavate the new underpass without affecting water service to the surrounding customers. Phase II of the water pipeline relocation work will generally include the construction of approximately 1,280 linearfeet of thirty-six inch diameter steel water transmission pipeline, 110 linear feet of 48-inch steel casing pipe to be bored and jacked beneath the railroad tracks, 140 linear feet of twelve-inch ductile iron pipe, 840 linear feet of eight-inch ductile iron pipe, five domestic water services and four fire hydrants, along with all other related fittings and appurtenances. It is anticipated that only minimal paving work will be required, as the Phase II pipeline work falls almost entirely within the subgrade of new streets that will be constructed as part of the overall grade separation project. The lowest responsive bid was received from Griffith Company in a total amount of$16,485,716.50. The water related portion of the bid was $1,187,945. The City Council is scheduled to consider awarding a construction contract to Griffith Company in October 2012.
