About the company

Rehbein Enterprises Inc., a HUBZone-certified Native American-owned woman-owned small business based in Plains, Montana, operates as a prime contractor delivering heavy and civil engineering construction, environmental restoration, and facilities maintenance to federal agencies across the interior West. The company is an SBA-certified 8(a) economically disadvantaged business, a Self Certified Small Disadvantaged Business, and holds Indian Economic Enterprise and Joint Venture Woman Owned Small Business designations; it competes under set-aside vehicles (8(a) Sole Source, Total Small Business, Indian Economic Enterprise) on the majority of its recent work, with a portfolio that is 100% prime awards across 84 total contracts and indefinite-delivery vehicles.

Rehbein's capability footprint centers on ground-level environmental and infrastructure work: shoreline protection and beach fill, erosion control and wetland restoration, road resurfacing and reconstruction, culvert and drainage installation, riprap and gabion work, quarrying and pit operations, equipment replacement and mechanical upgrades (variable frequency drives, firing range systems), and facilities grounds maintenance. Recent representative work includes a $2.33 million firm fixed-price definitive contract from the Bureau of Reclamation (awarded September 2026) for shoreline protection and beach fill at Speelyi Beach on Cle Elum Reservoir in Washington under an Indian Economic Enterprise set-aside; a $997 thousand delivery order under a USDA Natural Resources Conservation Service Indefinite Delivery Contract for easement restoration in South Dakota, extended through September 2026 due to weather delays; a $710 thousand Forest Service contract (April–December 2022) to resurface 14 miles of road and quarry pit-run material near Salmon, Idaho under the Great American Outdoors Act; and a $1.88 million 8(a) Sole Source award from the Bureau of Reclamation to replace variable frequency drives at the Folsom Pumping Plant in California. The company also holds a single-award Blanket Purchase Agreement with Customs and Border Protection for lawn care and landscaping services at port-of-entry facilities, valued at $1.1 million through May 2027.

Customer concentration is sharp and geographically anchored to the interior West. The top five agencies account for 70% of awards by count and 85% of combined potential value. The Department of Agriculture Forest Service R1-Northern Region dominates the portfolio with 32 awards valued at $29 million combined potential value, followed by the Bureau of Reclamation (5 awards, $11.6 million), the USDA Natural Resources Conservation Service Central Region (8 awards, $11 million), the USDA Under Secretary for Farm Production and Conservation (3 awards, $3.4 million), and the General Services Administration Public Buildings Service Region 8 (8 awards, $930 thousand). The portfolio skews toward contract completion in the past several years: activity peaked at eight awards in 2021, declined to six in 2022 and four in 2023, contracted to one award in 2024, and has resumed with two awards in 2026. Across the next twenty-four months, three awards (combined potential value $8.1 million) reach ultimate completion and face recompete.

Rehbein's work is predominantly self-performed. SCI-reported invoiced revenue on federal service contracts above the $150 thousand reporting threshold totaled $3.2 million across FY2022–FY2024, with peak activity in FY2022 ($2.1 million across 2.5 FTEs) followed by decline to $900 thousand across 3.6 FTEs in FY2024; FY2023 dropped to $229 thousand across 0.3 FTEs. Government-paid hourly rates on SCI-reportable prime contracts span a median of $181.99/hour, with senior labor pricing through $772.99/hour; the company maintains an 8% average sub-hours share across prime contracts and has engaged three named subcontractors in recent years. The company holds indefinite-delivery vehicles with the USDA (12FPC320D0001 supporting five task orders valued at $2.6 million combined potential value, and AG3C78C170012 supporting four task orders valued at $3.9 million). Rehbein Enterprises operates a named subsidiary, Montcal LLC, which holds parallel SBA designations including Indian Economic Enterprise, Joint Venture Woman Owned Small Business, HUBZone, and Self Certified Small Disadvantaged Business certifications.
