About the company
Thomas Dean & Hoskins Inc., doing business as TD And H Engineering, is a Great Falls, Montana-based consulting engineering firm that delivers civil, structural, mechanical, electrical, environmental, and water/wastewater design services to federal agencies as a prime contractor (95% of recent awards) and occasionally as a subcontractor on larger engineering programs. The firm competes predominantly under full-and-open vehicles, though it qualifies for and wins Total Small Business set-asides on Forest Service and Department of Interior contracts when designated. TD And H Engineering holds a subsidiary, GPD PC, and has maintained federal contracting registration since 2002.
The vendor's customer base is heavily concentrated in defense and civilian infrastructure portfolios. By award count, the Department of the Air Force Space Command dominates with 43 awards ($97.2 million potential value), followed by the Forest Service Region 1 Northern Region (22 awards, $12.3 million), the Air Force (22 awards, $157 thousand), Air Force Global Strike Command (22 awards, $782 thousand), and the Air National Guard (18 awards, $3 million). These five customers account for 65% of recent awards. However, by potential-value concentration, the profile shifts dramatically: the National Institutes of Health Construction represents a single $400 million multiple-award MATOC awarded in June 2026, followed by Air Force Space Command ($97.2 million), the Department of Interior Fish and Wildlife Service ($75 million across two vehicle holdings), Forest Service Region 6 ($25 million), and Forest Service Region 1 ($12.3 million). The NIH award and Interior vehicles together represent 97% of combined potential value, creating significant pipeline concentration in federal construction and infrastructure modernization.
TD And H Engineering holds five major parent vehicles spanning defense and civilian infrastructure. The Air Force Space Command's Malmstrom Air Force Base Architectural and Engineering IDIQ (FA462614D0002, awarded September 2023, $90 million ceiling through September 2027) carries 28 task orders ($2.8 million combined potential value) for mechanical, electrical, civil, structural, and fire-protection design across facility repairs, HVAC upgrades, water system improvements, and building envelope work. The Department of Interior Architecture and Engineering Services MATOC (W9124V05D0001, awarded September 2022, $50 million ceiling through September 2027) holds 21 task orders ($3.7 million) for professional land surveying, national forest boundary marking, vegetation management support, and facility assessments across Interior bureaus and the Forest Service. The Forest Service Region 6 Pacific Northwest Architecture and Engineering IDIQ (awarded September 2025, $25 million ceiling through September 2030) carries a Total Small Business set-aside and provides transportation, facilities, and environmental design services across Regions 6 and 10. The Department of Interior Geotechnical Engineering MATOC (12034320D0041, $25 million ceiling through April 2027) supports Great American Outdoors Act infrastructure projects. The NIH Construction FY26 A/E MATOC (awarded June 2026, $400 million ceiling through June 2032) is the firm's newest and largest vehicle, enabling task orders for facility planning, construction administration, and infrastructure design across NIH mission requirements. Representative task orders across these vehicles include a $330,714 Forest Service boundary survey and marking project (October 2023, Total Small Business set-aside), a $306,310 Malmstrom water tank repair design (April 2025), a $287,694 Forest Service bridge replacement design (September 2023, Total Small Business set-aside), and a $264,133 range relocation charrette at Mountain Home Air Force Base (September 2024).
Activity trajectory shows modest but consistent prime volume across the past five years — 13 awards in 2022, 16 in 2023, 17 in 2024, declining to 10 in 2025 and 4 recorded in 2026 through mid-year. The combined potential value of awards reaching ultimate completion within the next twenty-four months is $551 thousand, indicating minimal recompete cliff pressure at the prime level. However, the June 2026 NIH MATOC award creates a significant new revenue opportunity pipeline that substantially reshapes the firm's federal footprint toward federal construction and health infrastructure modernization.
In its subcontractor role, TD And H Engineering furnishes surveying, geophysical surveying, and engineering services to Jacobs Government Services Company (multiple sub-awards for Malmstrom Air Force Base consolidated maintenance facility and missile handling complex design, 2024-2026) and AECOM-Garver Kansas City Design Services JV (design-build RFP preparation for Fairchild Air Force Base aircraft parts warehouse, November 2024). These sub engagements represent specialized survey and geotechnical support rather than lead design or program management, aligning with the firm's core capability in measurement, analysis, and infrastructure documentation.
The firm's award portfolio concentration reflects a regional defense-and-public-lands customer base anchored in Montana and surrounding western states. Civil and structural engineering services dominate the NAICS and PSC profile, with 146 awards under Engineering Services (NAICS 541330), followed by Surveying and Mapping work (3 awards). The recent NIH multiple-award MATOC, however, signals a strategic pivot toward federal construction and institutional infrastructure design at scale, positioning the firm to compete for task orders across the National Institutes of Health campuses and associated federal construction projects nationwide.
