About this file
This solicitation package describes requirements for a new 40 ton intake gantry crane at Big Cliff Dam. The U.S. Army Corps of Engineers, Portland District is seeking to replace the existing intake crane with a new 40 ton gantry crane including a main hoist trolley and maintenance jib hoist. The new crane will provide for placement of spillway and penstock stoplogs and general servicing of the spillway deck. Accompanying the crane installation, the contractor must modify the existing cable reel power supply to a conductor rail and collector system, convert from a 3-wire to 4-wire power feed, and install emergency stop buttons. This is a hybrid supply and construction contract utilizing full and open competition. The solicitation will use the FAR Part 15.101-1 best value tradeoff source selection process.
