Added: Mar 07, 2018 4:32 pm The Department of Interior, Bureau of Reclamation, Pacific Northwest Region requires the construction of an Intake Structure, Helix and Gate Chamber at the Cle Elum Dam. The Intake Structure consists of six reinforced concrete intake structures stacked vertically that follow the existing reservoir rim contours and allow water and fish to be drawn into the juvenile facility over a reservoir water surface fluctuation of 63 feet. The water is controlled at each intake structure by an overflow weir crest gate. The water then flows to the juvenile facility through precast concrete conduits that range in length from 500 feet to 50 feet with the longest length being the bottom intake. The precast conduit transitions to a concrete encased steel pipe that penetrates through the secant pile shaft into the Gate Chamber.



The Gate Chamber houses an underground 6-story tall steel structure that supports the guard gate and steel pipe for each of the 6 intake levels within the previously constructed secant pile shaft. The size of the Gate Chamber is to provide the hydraulics required for the steel pipe transition to the helix structure. An access structure is provided in the Gate Chamber for entry and egress by a stairwell and elevator shaft.



The Helix Chamber houses an underground 48-foot diameter helix structure that dissipates the energy from transporting water and fish from a vertical distance of over 80 feet. The structural support system for the helix is a steel braced frame system that supports a precast concrete flume used to transport the water and fish. An access structure is provided in the center of the helix for entry and egress by a stairwell and elevator shaft.



The Gate and Helix Chambers are fully enclosed by a roof constructed with steel trusses and joists with a reinforced concrete deck. The applicable North American Industry Classification System (NAICS) is 237990 and the size standard is $36.5 million. The Davis-Bacon Act applies to this procurement.



We anticipate issuing a Request for Proposals (RFP) approximately 15 April 2018 at www.fbo.gov., but all dates in this notice are subject to change. Any amendments applicable to the solicitation will be posted at the same site. To take advantage of business opportunities with the Bureau of Reclamation (BOR) and the Department of the Interior (DOI) you must register your firm with the System for Award Management (SAM) at www.sam.gov.



Reclamation intends to award one firm fixed-price contract. The estimated price of the work is between $50,000,000.00 and $100,000,000.00. Any award will be based on the best value to the Government. This requirement will be solicited as a full and open procurement that will consider past performance and price in the award decision; these evaluation factors are subject to change. Final evaluation factors will be defined in the solicitation.
