Sisters Aggregate & Construction, L.l.c

Sisters Aggregate & Construction, L.L.C., a for-profit limited liability company based in Sisters, Oregon, operates as a prime contractor providing specialized freight transportation, aggregate delivery, construction materials, and heavy equipment rental to support wildland fire suppression, incident response, and forest stewardship across the U.S. Forest Service and Department of the Interior. The vendor competes exclusively on full-and-open (non-set-aside) delivery orders except for two small-business-set-aside indefinite delivery contracts with the National Interagency Fire Center, and holds no SBA certifications.

Sisters Aggregate's customer footprint concentrates heavily in the Pacific Northwest. The top four funding agencies account for 94% of awards by count and 100% of combined potential value, led overwhelmingly by the Department of Agriculture Forest Service's Pacific Northwest Region (40 awards, $1.7 million combined potential value) and followed distantly by the Forest Service's Fire and Aviation Management National Interagency Fire Center (4 awards, $1 million potential value). The Bureau of Land Management Idaho Region and Oregon-Washington field account for the remaining two awards. The vendor's recent activity shows declining volume—seven awards in 2022, eight in 2023, eleven in 2024, two in 2025, and one through February 2026—with no recompete cliff visible in the near term, though four indefinite delivery contracts expire or have expired between January 2024 and June 2030.

The vendor's work portfolio breaks into two capability streams. Specialized freight trucking and local transportation dominate the award count (26 awards under NAICS 491112), supported by forestry activities (21 awards under NAICS 561730) and equipment rental. Representative full-and-open delivery orders from the Forest Service Pacific Northwest Region include a $26.8 thousand order awarded July 19, 2024 for construction and materials delivery, a $27.9 thousand order from August 18, 2023, and a $23.7 thousand order from July 21, 2024, all firm fixed price for landscape protection and stewardship. Sisters Aggregate holds two small-business-set-aside indefinite delivery contracts worth $250 thousand each through the National Interagency Fire Center's Virtual Incident Procurement (VIPR) I-BPA program: one for miscellaneous heavy equipment rentals in Forest Service Regions 3, 5, and 6 (awarded January 31, 2022; expired May 29, 2024) and another for refrigerated trailer services across Regions 1, 2, 3, 4, 5, 6, 8, and 9 (awarded June 3, 2025 and February 6, 2026; extends through June 3, 2030). Task orders under these vehicles and legacy BPAs range from $2.3 thousand to $28 thousand. The vendor operates exclusively as a prime (100% of awards) with no subcontract footprint.

Combined potential value across all 49 awards totals $2.7 million, with $1 million (37%) obligated to date. The award portfolio spans back to 2005 in source records, positioning Sisters Aggregate as an established regional vendor for emergency equipment deployment and materials support on public lands, but with modest recent momentum and concentration in a narrow geographic and mission set.
