GPD PC

GPD PC, a small disadvantaged business subsidiary of Thomas Dean & Hoskins Inc. headquartered in Great Falls, Montana, delivers architectural and engineering services to federal agencies and defense installations as a prime contractor (100% of awards) under delivery orders on multiple-award IDIQs and single-award vehicles. The vendor specializes in facility design, infrastructure modernization, mechanical and electrical systems engineering, and construction support, with a geographic footprint concentrated at Rocky Mountain Laboratories in Hamilton, Montana and Malmstrom Air Force Base in Great Falls, Montana.

The vendor's customer base is dominated by two agencies that account for the entirety of its recent award portfolio. The National Institutes of Health Construction anchors the dollars side with eight awards totaling $402.8 million in combined potential value, driven by a single $1.7 million construction bridging documents order on Building J (FY2023) and several design and infrastructure study awards on the Rocky Mountain Laboratories campus, including $498,488 for the Building 28 Chiller Plant Expansion final design and $120,317 for the Building 28 Chemical Storage Area Study. The Department of the Air Force Space Command dominates the award count with 39 orders totaling $98.4 million, anchored by a $90 million IDIQ for architectural and engineering services at Malmstrom AFB (awarded September 28, 2023, with a seven-year term through September 27, 2030) and populated by task orders for facility repairs and design work. The Air Force Global Strike Command accounts for 27 awards ($2.9 million combined potential value), primarily for electrical and fire-suppression design services. The Air National Guard and Air Education and Training Command round out the customer set with minimal volume.

GPD PC places task orders under four primary vehicles: two Air Force Space Command indefinite delivery contracts (FA462615D0002 with 30 orders and FA462609D0003 with 28 orders, combined $3.9 million potential value), the NIH Architect Engineering MATOC with seven orders totaling $2.8 million, and the Malmstrom AFB AE IDIQ with four orders. Recent awards include a $413,698 delivery order (April 2024) for roof and exterior repairs at Malmstrom's Missile Communications Facility B165, a $79,232 order (October 2025) for Type A and Type B design documents to replace electrical service panels at Malmstrom, and a $157,526 site electrical study order (July 2026) at Rocky Mountain Laboratories under the NIH vehicle.

The vendor's activity trajectory shows minimal recent volume: one award in 2025, one in 2026, and a recompete exposure of $158 thousand across one award completing in the next twenty-four months. SCI-reported invoiced revenue totaled $228 thousand in FY2023 on a single contract, delivered across 0.4 FTEs with a government-paid rate of $245.25 per hour. The vendor self-performs all reported work with no subcontractor engagement. GPD PC operates as a subsidiary of Thomas Dean & Hoskins Inc., a for-profit engineering and construction services firm based in Great Falls, which itself holds prime positions on federal A&E vehicles and likely provides corporate oversight and shared resources.
