T & S Cheff Construction, Inc.

T & S Cheff Construction, Inc., doing business as T S Construction, is a for-profit small business based in Kalispell, Montana, that provides heavy equipment rental, operators, and construction services to the U.S. Forest Service and the National Interagency Fire Center as a prime contractor under total small business set-asides. The vendor operates exclusively as a prime (100% of awards) and competes across all recent awards under small business set-aside designations.

T S Construction's federal footprint centers on wildland fire suppression and forestry operations across the northern and eastern zones of the National Interagency Fire Center. The vendor's capability portfolio includes provision of heavy equipment—dozers, excavators, feller bunchers, graders, mulcher/masticators, and skidders—paired with certified equipment operators and project-management personnel to support emergency response and prescribed fire work. Representative work includes a $64,350 firm fixed price delivery order from the Forest Service issued August 5, 2026, for unspecified construction services in Kalispell; a $96,992 delivery order from the Forest Service awarded August 27, 2023, for construction and facilities management support in Montana; and a $62,400 delivery order from the Forest Service issued July 31, 2023, for construction services and heavy equipment support in Kalispell.

Customer concentration is absolute and narrow. Ten awards (100% of the source footprint) split between three customer sub-offices of the Department of Agriculture: the National Interagency Fire Center (6 awards, $2 million combined potential value), the Forest Service general office (3 awards, $224 thousand), and Forest Service Region 1–Northern Region (1 award, $57 thousand). The vendor holds position on two Indefinite Delivery Contracts under the National Interagency Fire Center: Indefinite Delivery Contract 1202SB21T7174, which carries 3 task orders worth $216 thousand combined, and Indefinite Delivery Contract 1202SB24T7359, which carries 1 task order worth $64 thousand. Two additional IDCs awarded in February and May 2026 establish a $1 million combined ceiling through 2028–2029 for heavy equipment provision to the East Zone across Regions 1, 2, 4, and 9.

Activity remains light and episodic. The vendor received one award in each of 2021 and 2022, three in 2023, one in 2024, and three in 2026; combined potential value sits at $2.3 million against $281 thousand in obligated dollars (12% draw-down). All work maps to NAICS 561730 (Support Activities for Forestry) and PSC Natural Resources/Conservation code. T S Construction has no subcontract relationships in the source data and operates as sole prime across all awards. The vendor is not known to hold a position on government-wide IDIQs, GWACs, or agency-wide BPAs beyond the National Interagency Fire Center vehicles.
