The U.S. Army Corps of Engineers Engineering District Portland is soliciting bids for the fabrication, delivery, and installation of twelve concrete stoplogs at the Bonneville Navigation Lock, along with associated dredging work at the Bonneville Lock and Dam facility located in North Bonneville, Washington and Cascade Locks, Oregon.

The solicitation has undergone multiple amendments, with the final bid submission deadline extended to October 2, 2025 at 2:00 PM Pacific, and liquidated damages established at $3,450 per calendar day for delays beyond physical completion.

This procurement is designated as a total small business set-aside under NAICS code 237990 (Other Heavy and Civil Engineering Construction) and PSC code Y1KA (Construction of Dams). Four companies submitted bids: SNC Core JV LLC, Winspear Construction LLC, HME Construction Inc., and Doyon Government Group Inc., with total evaluated prices ranging from $6,634,836 to $9,720,500 compared to the Independent Government Estimate of $9,107,000.

Work will be performed at the Bonneville Lock and Dam in both Washington and Oregon, with contractors required to follow strict environmental and safety guidelines including potential handling of lamprey larvae and coordination with marine traffic operations.
