BM - station service D1A bus

The Bureau of Reclamation is soliciting proposals for the replacement of the 480-Vac Station Service D1A Non-Segregated Bus at the Blue Mesa Powerplant in Montrose, Colorado. The project involves removing and replacing two runs of 1,600 ampere copper nonsegregated-phase bus between Transformers KRB and KRC and the Station Service D1A switchgear, including associated conduits, hardware, and installation of new bus runs with flexible connections, support structures, and electrical heaters. The work must be completed during a single power outage scheduled between September 2025 and April 2026, with the contractor responsible for detailed design drawings, factory and field testing, thermographic surveys, and comprehensive documentation. Proposals are due August 21, 2025, at 5:00 PM Mountain Time, following a mandatory site visit held on August 7, 2025. The evaluation will be based on three factors: Construction Schedule, Past Performance, and Cost/Price, with the non-cost factors considered significantly more important than price.

This opportunity is designated as a Total Small Business set-aside under solicitation number 140R4025R0012. The procurement is for one unit with technical specifications including bus ratings of 600-volts, 1,058-volts maximum, and a momentary withstand current rating of 97kA peak. The work is located at the Blue Mesa Powerplant approximately 40 miles east of Montrose, Colorado in Gunnison County, operating under the Colorado River Storage Project. The contract will be awarded as a firm fixed-price construction contract, with proposals required to remain valid for 90 days from the closing date. The solicitation falls under NAICS code 237130 (Power and Communication Line and Related Structures Construction) and requires compliance with various federal regulations including Buy American Act requirements and small business provisions.
