Sean Mergenthaler Construction LLC

Sean Mergenthaler Construction LLC, a self-certified small disadvantaged business headquartered in Bozeman, Montana, operates exclusively as a prime contractor providing heavy equipment rental services to the Department of Agriculture Forest Service for wildland fire management and emergency response operations. The vendor competes entirely under total small business set-asides and holds two active indefinite delivery contracts with the Forest Service covering Regions 1, 2, 4, and 9 through June 2028.

The vendor's customer base is highly concentrated and functionally monolithic. All fourteen awards in the source span two Forest Service entities — Region 1 (Northern Region) with nine awards totaling $208 thousand combined potential value, and the National Interagency Fire Center with five awards totaling $1.3 million. The two rankings align completely: NIFC dominates the dollar value while Region 1 anchors the award count. The vendor draws all work from Forest Service fire-suppression and emergency-response demand, with no diversification across other federal agencies or mission areas.

Sean Mergenthaler's vehicle position consists of two indefinite delivery contracts. The primary vehicle is Indefinite Delivery Contract 1202SB23T7502, awarded June 1, 2023, with a $250 thousand ceiling through June 2028, generating nine task orders totaling $208 thousand. A second vehicle, Indefinite Delivery Contract 12034320T7179, was awarded February 6, 2026, with a $750 thousand ceiling and ultimate completion June 1, 2028, carrying two task orders worth $64 thousand. Both vehicles are total small business set-asides procuring heavy equipment rental — excavators, dozers, tractor plows, and equipment transports — under firm fixed-price delivery orders for fire suppression and all-hazard incident support.

Activity has grown substantially: two awards in 2021, then flat through 2023, then three in 2025 and five in 2026, reflecting acceleration in the past twelve months. Combined potential value across all awards stands at $1.5 million; combined dollars obligated total $272 thousand (18% of ceiling). All fourteen awards classify under NAICS 541712 (Support Activities for Forestry) and PSC Natural Resources/Conservation—Forest-Range Fire Suppression/Presuppression. Place of performance spans Helena and Dillon, Montana, and Albuquerque, New Mexico, with all work routed through the two Forest Service indefinite delivery vehicles. Recent delivery orders include a $36.5 thousand equipment rental issued August 2, 2026, a $30.8 thousand order issued May 19, 2026, and a $9.1 thousand order issued July 27, 2026, all to Region 1 for fire suppression support with completion dates measured in days, reflecting the urgent, emergency-response character of the work.
