Daniel M Siderius

Daniel M Siderius, doing business as Dan Siderius Construction & Excavation, is a sole proprietorship based in Kalispell, Montana, that provides heavy equipment operation and construction-excavation services to the U.S. Forest Service as a small-business set-aside prime contractor. The vendor operates exclusively under Total Small Business set-asides across its federal footprint.

The vendor's capability portfolio centers on wildland fire suppression, incident response, and federal land management support. Dan Siderius supplies and operates heavy equipment including dozers, excavators, feller bunchers, skidders, tractor plows, and log loaders across Forest Service regions in the Northern Tier (Regions 1, 2, 4, and 9). Representative recent work includes a $384,159 firm fixed-price delivery order from the Forest Service issued July 30, 2026, for land and timber management operations in Kalispell, Montana; a $166,100 delivery order from August 2023 for construction and excavation services supporting Forest Service operations; and a $124,800 purchase order from August 2023 for log loader equipment supporting timber harvesting. All work is performed in or near Kalispell, Montana, with performance extending across Forest Service Region 1 and subordinate regional locations in the Northern, Rocky Mountain, Intermountain, and Eastern regions.

Customer concentration is extremely narrow: 86% of awards derive from three subdivisions of the Department of Agriculture Forest Service — the National Interagency Fire Center (11 awards, $3.8 million combined potential value), the R1-Northern Region (20 awards, $1.7 million), and the broader Forest Service organization (14 awards, $1.3 million). The vendor holds eight indefinite-delivery contracts with the Forest Service and National Interagency Fire Center, each with ceilings of $250,000 to $500,000, awarded between June 2023 and February 2026 and running through 2028–2030. These contracts support heavy equipment task forces and incident blanket purchase agreements for Forest Service Regions 1, 2, 4, and 9. Task orders have been issued across multiple BPA vehicles including AG0343B157095 (5 task orders, $469 thousand combined potential value), IDC 1202SB23T7359 (3 task orders, $187 thousand), and several others with smaller order volumes.

Activity shows seasonal volatility consistent with fire-suppression and land-management cycles: three awards in 2022, six in 2023, one in 2024, two in 2025, and seven in 2026. The vendor operates as a 100% prime contractor with no sub-award footprint. Combined potential value across all 56 awards is $6.7 million, with $2.9 million (44% of potential) obligated. The vendor's work is concentrated in NAICS 238910 (Support Activities for Forestry) and PSC code R406 (Natural Resources/Conservation—Forest-Range Fire Suppression/Presuppression), which account for 52 and 54 of the 56 awards respectively.
