About the company
Tunnell Spangler & Associates Inc., doing business as TSW, is a self-certified small disadvantaged business providing architectural, engineering, and landscape architecture services to the Department of Agriculture Forest Service as a prime contractor on planning, design, and construction administration work for federal recreation and forest management facilities across the southeastern United States.
TSW is based in Atlanta, Georgia, and operates exclusively as a prime contractor (100% of recent awards) under total small business set-asides across most of its portfolio. The vendor specializes in facility planning, architectural design, landscape architecture, and engineering drafting services with primary NAICS concentration in 541310 (Architectural Services) and 541330 (Engineering Services), according to the source data spanning 2011 to the present.
Customer concentration is extreme. All 23 awards in the source dataset come from the Department of Agriculture Forest Service Southern Region (Region 8), with 22 awards valued at $10 million combined potential value and one additional award to the parent Forest Service agency valued at $111 thousand. This single-agency dependency leaves TSW vulnerable to recompete cycles within one customer organization. TSW places task orders under three parent IDIQ vehicles: Indefinite Delivery Contract 1243ZP18D0002 (6 task orders, $782 thousand combined potential value), Indefinite Delivery Contract 12445221D0018 (5 task orders, $2 million combined potential value), and Indefinite Delivery Contract AG43ZPC120003 (4 task orders, $75 thousand combined potential value). The largest IDIQ carries a $6 million ceiling awarded September 28, 2021.
Recent representative work includes a $180,380 definitive contract for Croatan RDO architecture and engineering support and commissioning awarded May 26, 2026 (ultimate completion December 31, 2026); a $904,806 delivery order for the MS Ohkissa Lake Recreation Master Plan Development awarded August 12, 2024 (ultimate completion January 31, 2027); and a $676,455 delivery order for complete architectural and engineering designs and construction documents for a new ranger station and modified helibase awarded June 19, 2023 (ultimate completion December 31, 2025).
Activity has been episodic. Awards occurred in 2021 (3), 2022 (2), 2023 (3), 2024 (1), and 2026 (1), with a gap in 2025. Three awards with combined potential value of $1.4 million face ultimate completion within the next twenty-four months, creating near-term recompete exposure. According to the Service Contract Inventory, TSW invoiced $383 thousand in federal service contracts above the $150,000 threshold across FY2023–FY2024, with 0.2 FTEs in FY2023 and 0.4 FTEs in FY2024. On SCI-reportable work, government-paid hourly rates ranged from $155.90/hr at the tenth percentile to a median of $214.43/hr and $326.96/hr at the ninety percentile, reflecting mid- to senior-level professional labor. TSW self-performs all work with zero subcontractor hours reported across SCI records.
