AI Contract Overview
The contract entails the comprehensive upgrade of the hydraulic system at Dashields Locks and Dam in Coraopolis, Pennsylvania, involving the complete demolition and removal of the existing hydraulic infrastructure including motors, pumps, reservoirs, piping, valves, and fluid, with embedded piping to be drained, cut flush, and abandoned in place. Nine new hydraulic cylinders will be supplied by the contractor, with five provided by the government, alongside three new hydraulic power units (HPUs) to be installed in two newly constructed two-story buildings on the land and middle lock walls, and a fourth HPU on an elevated platform in the river wall. The contractor is responsible for designing and constructing the HPU buildings and control shelters according to provided performance specifications and concept drawings. Hydraulic power will be distributed via new stainless-steel piping and manifold-mounted components to the existing cylinders, controlled by new electronic systems housed in panels and consoles located inside the HPU buildings and three existing and one new one-story control shelter. Electrical demolition includes removal of buckets, junction boxes, wiring, and hardware, while new cabling and hardware must be installed within existing motor control centers. Concrete work is required for building foundations, utility trenches, and pipe routing, and a geotechnical analysis must verify structural integrity and drainage. Minimal steel grating will cover new utility trenches. All new equipment must undergo full testing and commissioning before handover. Due to the project’s location on the Ohio River, construction will require a floating work plant and work boats. All as-built drawings must be stamped by a registered professional engineer. The contract has a 730-day performance period following notice to proceed and is a firm-fixed-price award with a total small business set-aside under NAICS code 237990, with a size standard of $45 million. Offerors must be registered in SAM.gov with an active status and in PIEE’s Solicitation Module with the Proposal Manager role, and submission is required through PIEE with no hardcopy solicitations permitted. The solicitation will be issued June 18, 2026, with bids due the same day, and technical point of contact is Aaron Barr of the U.S. Army Corps of Engineers.
