Gaoa finale DAM reconstruction

The Bureau of Land Management (BLM) is seeking sources for the GAOA Finale Dam Reconstruction project located in Valley County, Montana, approximately 41.5 miles southwest of Glasgow. The project involves comprehensive dam reconstruction services, including dewatering the reservoir, excavating the existing dam embankment, constructing new outlet works with precast concrete structures, building an auxiliary spillway, placing gravel road surfacing, and reclaiming disturbed areas. Interested businesses are required to submit detailed responses by June 12, 2025, at 5:00 PM MDT, providing company information, business classification, bonding capacity, and demonstrated experience in dam construction. The BLM will use these responses to develop an acquisition strategy and determine potential small business or socio-economic set-asides. Evaluation criteria will focus on companies' capabilities, past performance in heavy civil engineering construction, and ability to meet the technical specifications outlined in the draft project documents.

The pre-solicitation notice indicates no specific set-aside designations at this time, with the NAICS code 237990 for Other Heavy and Civil Construction and a small business size standard of $45.0M. The anticipated construction magnitude is between $1M-$5M, with a planned performance period of 431 calendar days. The solicitation is scheduled for release in July 2025, with bid, performance, and payment bonds expected to be required. The project involves reconstructing an existing dam infrastructure, including constructing a precast concrete outlet works riser, a concrete-encased reinforced concrete pipe outlet conduit, a low-level inlet structure, a grouted riprap stilling basin, an auxiliary spillway, and road gravel surfacing on the dam crest. Technical specifications emphasize precise materials placement, quality control, and long-term performance of the reconstructed dam infrastructure.
