Foster Spillway Gate Nut Replacement and Re-Tensioning RFP

Description: The U.S. Army Corps of Engineers, Portland District posted a Sources Sought notice for work on the Foster spillway gates. The scope calls for replacing 192 custom castle nuts, 48 U-bolts, eight U-bolt spacers, eight gate connection pins, and one custom installation tool, with specified materials and dimensions. After the hardware is replaced, the contractor must release and re-tension each gate’s wire ropes so the gate clears the sidewalls and bears evenly on the spillway ogee; the notice contemplates one firm-fixed-price contract.
