What Structural Associates does

Structural Associates, Inc. (SAI) is a privately held federal construction contractor founded in 1970 and headquartered in East Syracuse, New York, with regional offices in Watertown, NY and Portsmouth, NH. The company delivers general contracting, construction management, design-build, and program management services exclusively to U.S. federal government clients, with the Department of Defense and military installations representing its dominant end market. Across 50+ years of operation, SAI has completed projects totaling over $700 million spanning aviation infrastructure (hangars, runways, aprons), military fueling distribution systems (hydrant systems, storage tanks, pumphouses), and federal/DoD facilities including training centers, medical clinics, lodging, and administrative buildings.

SAI pursues federal contracts directly through SAM.gov solicitations, sealed bids, design-build competitions, and negotiated contracts, serving as prime contractor or construction-manager-as-agent. The firm self-performs select construction scopes including concrete placement (recognized with an ACI Design and Installation Gold Award) while managing multi-disciplinary design consultants and specialty subcontractors for larger programs. Recent flagship projects include a $29 million Railhead Loading Facility at Fort Drum, NY, a $33 million Aviation Brigade Facility Complex with Blackhawk/Chinook hangar, a $27.5 million fuel facilities replacement on San Clemente Island, and a $21 million UAS Shadow Hangar at Wheeler Sack Army Airfield.

SAI's competitive position rests on regulatory credentials maintained for decades (ABC Accredited Quality Contractor since 1993, STEP Safety Award annually since 2000, 2004 ABC National Contractor of the Year), deep domain specialization in military fueling and aviation airfield work, and a documented past-performance record with NAVFAC, U.S. Army Corps of Engineers, Air National Guard, and other federal agencies. The company pursues capacity expansion through joint ventures (e.g., Kondra/SAI-JV for small-business set-aside work) and broadens its addressable market by executing projects across the continental United States. The firm has no disclosed external funding, no parent company, and operates with a small core employee base of 11-50 staff.
