Roberts, CONTRACTING OFFICER This is a Sources Sought Announcement is essentially for firms having the capability to provide stormwater pumps for the West Columbus, Ohio, IIID project. The 4 pumps which shall also include (1ea 20,000 GPM @ approx. 33 feet TDH and 3ea 40,000 GPM @ approx. 33 feet TDH) we also want to include purchase of the Formed Suction Intakes (FSI), the pump tubes, elbows, and flap valves for each of the four pumps. Construction work at West Columbus will not start until sometime in 2000. However, the Government is anticipating delivering of the pumps by September 1,1999. Pumps are to be submersible electric type. The vertical axial or mixed flow pumps shall have direct coupled electric motors that operate from 2,400 VAC, 3 phase power. The pumps will be set in vertical pipes supported from operating floor above. Discharge will be out the side of the pipe or tube through a horizontal wall pipe and flap valve into the discharge chamber. Intakes to the pumps will be mated to Formed Suction Inlets (FSI). The design of the FSIs will be in accordance with Corps standards where all dimensions relate to pump inlet diameter. Critical elevations are stated below: Top of Discharge Chamber 718 Pump Station Operating Floor 703 Ground Elevation 702 Centerline Discharge From Tube 698 Approx. Pump Station Floor (Sump) 669 Note these values are approximate and subject to change as our design evolves.
