About the company
Diamond West Construction LLC, a service-disabled veteran-owned small business (SDVOSB) based in Scottsdale, Arizona, operates predominantly as a subcontractor (67% of recent awards) on defense research and industrial construction programs, with limited direct prime work in building maintenance and repair. The company is an SBA-certified self-disadvantaged business and veteran-owned LLC competing under set-aside vehicles; its recent prime activity concentrates on total small business and SDVOSB set-asides.
Diamond West's award footprint is heavily skewed toward defense research infrastructure. Four of six recent awards are subcontracts to Northrop Grumman Systems Corporation supporting next-generation interceptor (NGI) all-up-round development and DARPA industrial building construction work, all falling under DOD Missile Defense Agency and Defense Advanced Research Projects Agency funding. The company's two prime contracts, by contrast, are small facility-maintenance tasks: a $22,043 purchase order from USDA's Plant Protection and Quarantine for steam chamber repair and door replacement at a Phoenix facility (August 2026), and a $993,878 definitive contract from the Department of Veterans Affairs for reroofing and post-completion maintenance at Jack C. Montgomery VA Medical Center in Muskogee, Oklahoma (awarded December 2025, completion by July 2026). The VA reroofing work, which represents 99% of the company's combined potential value across all awards, includes removal and replacement of roof systems across approximately 7,840 square feet, R-33 insulation installation, perimeter flashing and roof drain hardware replacement, one year of maintenance and inspection services, and engineering support transfer to VA staff. NAICS category concentration splits between research and development in the physical, engineering, and life sciences (four awards) and roofing contractors (one award).
Activity accelerated modestly from one award in 2024 to three in 2025, with two awards in 2026; combined potential value across all six awards totals $1 million, though combined obligated dollars reach $1.1 million. Customer concentration spans four agencies, with the Veterans Health Administration anchoring 99% of potential value, while the three Northrop Grumman subs under DOD Missile Defense Agency and DARPA represent volume but carry minimal individual dollar visibility. The VA reroofing contract faces completion by July 2026 and will recompete in the twenty-four-month window; the Northrop Grumman engagement chain appears to be ongoing research-phase work with serial task additions across 2024–2026 rather than a single time-bound delivery.
