F.D. Thomas

What F.D. Thomas does

F.D. Thomas (FDT) is a U.S. specialty contractor founded in 1979 and headquartered in Central Point, Oregon, operating through four wholly owned subsidiaries — F.D. Thomas, FDT Structural Specialties (FDTSS), D. Zelinsky & Sons (since 1884), and D2 Industrial Services — with Redwood Painting Company added in January 2023. Since 2018 the company has been a wholly owned subsidiary of AIS (ASRC Industrial Services), itself a subsidiary of Arctic Slope Regional Corporation (ASRC), an Alaska Native corporation, which provides 8(a) and ANC contracting advantages. The company delivers five core service lines: industrial painting and specialty coatings, waterproofing/sealants/roofing, specialty contracting (FRP composites, concrete and masonry restoration, seismic retrofit), commercial painting, and industrial insulation/scaffolding/abatement.

The business is project-based and B2B, executing work both directly for enterprise facility owners and through general contractors on new construction. Customers include marquee sports venues (SoFi Stadium, Chase Center, Golden 1 Center, Globe Life Field), high-tech manufacturing (Tesla Gigafactory, Salesforce Tower, a confidential semiconductor fab), nuclear energy (Plant Vogtle Units 3 & 4 for Southern Nuclear/Bechtel), refineries and utilities (Valero Benicia, PG&E), and government infrastructure (Caltrans, U.S. and state governments). Pricing is determined per project by scope and specification; the company does not publish rates.

Underlying technical capability rests on certified craft labor, an in-house SSPC QP-3 certified Industrial Coating & Lining Facility in Rancho Cucamonga, CA (opened 2020), and an unusually dense credential stack — NQA-1 (nuclear), AMPP QP-1/QS1/QP-2/QP-3/QP-8, SSPC QP-3, OSHA VPP, and a 2025 Highwire Safety Platinum Award — which collectively gate entry to nuclear, semiconductor, federal, and high-spec industrial coating work. The company maintains offices in California, Oregon, Washington, and Maryland and reports a workforce of 251–500 employees.
