The Replacement of the Existing Water Siphons between Brooklyn and Staten Island RFP
New York City Economic Development Corporation (NYCEDC) is seeking a consultant to provide construction project oversight and resident engineering services (the Consultant) for the Replacement of the Existing Water Siphons between Brooklyn and Staten Island Project (the Project). The general purpose of the Project is to construct a new 72-inch diameter water transmission pipeline installed in a 12-foot diameter tunnel beneath the New York Harbor, between Brooklyn and Staten Island, New York. Upon completion of the new pipeline, two existing shallow pipelines (the existing siphons) will be abandoned. This in turn will allow completion on an ongoing project to increase the depth of shipping channels in the harbor.
Approximately 36 inches in diameter, existing Siphon #1 extends from 79th Street in Brooklyn to a pump station on Victory Boulevard, Staten Island, just east of Bay Street, where it feeds into Staten Islands Silver Lake Reservoir. Approximately 42 inches in diameter, existing Siphon #2 extends from 86th Street in Brooklyn to the Staten Island water supply system terminus at Vanderbilt Avenue. The siphons are critical to ensuring a backup water supply to Staten Island.
Respondents must be able to provide pre-construction, construction and post-construction management and other related services as more specifically set forth in the Contract Draft and Scope of Services annexed to the RFP including, without limitation, the following: participation in pre-bid conference with invited bidders for construction contract, evaluating bids for the construction contract and pre-award conferences with the selected construction contractor; participation in the review of any pre-award submittals from the construction contractor such as preliminary schedules and information concerning proposed alternative materials or methods; constructability reviews; cost estimating and value engineering exercises; Project controls, requisitions, change orders and other contract documents and processes.
