Decon Engineering Inc.

Decon Engineering Inc., doing business as DEI Consulting, operates as a prime contractor (93% of recent awards) delivering engineering design, commissioning, facilities maintenance, and technical support services to federal agencies, with 15 awards totaling $16.5 million in combined potential value across a fifteen-year footprint spanning 2007 to 2023. The Sterling, Virginia-based firm is a for-profit corporate entity competing in full-and-open procurements without named SBA set-aside designations; its recent activity is sparse and declining, with a single award in 2023 following earlier clusters in 2010–2011 and 2018–2019.

Customer concentration centers on the Department of Veterans Affairs Headquarters (4 awards, $8.8 million combined potential value) and GSA Federal Acquisition Service (2 awards, $7.1 million), accounting for 73% of recent awards by count and 99% by combined potential value. The VA represents the anchor customer and sole driver of dollar concentration; GSA's contribution reflects vehicle position rather than distinct customer relationships. The Department of the Interior Bureau of Indian Affairs Navajo Region, the Department of Homeland Security US Coast Guard, and a GSA Public Buildings Service regional office round out the active customer set, though with minimal dollar exposure.

Decon Engineering operates across two primary parent vehicles: the GSA Multiple Award Schedule, where 11 task orders carry $12.1 million in combined potential value, and a Facilities Maintenance and Management vehicle, under which 4 task orders total $8.8 million. The vendor's work splits primarily across NAICS Engineering Services (12 awards), with secondary exposure in Electrical Contractors and Other Wiring Installation Contractors and All Other Specialty Trade Contractors. PSC coding emphasizes Support—Professional (Engineering/Technical), Other Quality Control/Test/Inspect—Miscellaneous, Electrical Control Equipment, and Maintenance/Repair/Rebuild of Equipment. Representative recent work includes the February 2023 sub-award under Balfour Beatty Construction for P3003 commissioning at Joint Base Andrews' consolidated communication center.

GSA Schedule labor portfolio spans ten categories at rates from $72.58 to $347.15 per hour, ranging from Administrative Assistant to Principal roles, all requiring bachelor's degrees and no security clearances. The spectrum covers technical writers, communications specialists, engineers at multiple seniority levels, and energy managers, supporting a generalist professional-services posture grounded in facilities and infrastructure work rather than classified or defense-focused capability.

Activity has contracted substantially. The five-year window shows one award in 2023, one in 2019, three in 2018, and five clustered in 2011, following a 2010 entry. Combined dollars obligated stand at $9.4 million (57% of combined potential value), signaling incomplete funding or work on some awards. No active recompete exposure or subcontractor teaming relationships are evident in the recent award history beyond the single Balfour Beatty sub-award.
