Wyoming NER Percolation and Groundwater Testing

The contract pertains to percolation testing and groundwater monitoring at the Wyoming National Elk Refuge to support the design of a replacement septic system for Quarters No. 3, which originally dates to 1929 and is no longer functional. Work is scheduled to occur between August 1, 2026, and October 31, 2026, and includes conducting a minimum of three percolation tests in 3-foot trenches, excavating hand-dug test holes, and extending soil profile pits to a depth of 8 feet below ground surface. A qualified geotechnical engineer must log all soil profiles, and groundwater monitoring must be conducted using a contractor-recommended method from spring through summer 2026. All deliverables—including soil data, test results, and monitoring reports—must be submitted electronically in PDF format to the Contracting Officer, Contracting Officer’s Representative, and National Elk Refuge point of contact for review and approval. The work must comply with Teton County percolation requirements and applicable federal, state, and local regulations, and testing must be performed by NRTL- or NVLAP-accredited agencies. The contract is issued as a sealed bid under a total small business set-aside with NAICS code 541620 and solicitation number 140FGA26R0030. Proposals must be submitted by 3:00 PM local time on July 17, 2026, to the GAOA office in Falls Church, Virginia, with electronic submissions accepted via email or file share and physical submissions via sealed envelope. Performance and payment bonds are not required, and contractors must comply with Davis-Bacon Act wage requirements. The Contracting Officer’s Representative is Leonard Brown, with Sean Brophy serving as deputy support, but no Contracting Officer name is provided. No detailed pricing, line items, or contract value are specified, and the award basis is not explicitly stated, though the sealed bid format implies a firm-fixed-price contract awarded on a lowest price technically acceptable basis. No formal list of attachments, evaluation factors, or special contract requirements beyond bonding and labor compliance are included in the documentation.
