Roso Construction Inc.

Roso Construction Inc., a woman-owned small business based in Berwyn, Illinois, operates as a prime contractor providing specialized construction, electrical, and facility maintenance services to the U.S. Army Corps of Engineers. All three awards in the recent record are primes under Total Small Business or no set-aside designations, with work performed entirely at the Lockport, Illinois aquatic facility.

Roso's federal footprint is concentrated within the Army Corps of Engineers, which accounts for all three awards and $122 thousand in combined potential value. The Chicago District Engineering office (ENDIST Chicago) issued two awards totaling $78 thousand, while the Army Corps of Engineers proper issued one award of $43.7 thousand. Recent capability work includes a $41.7 thousand firm fixed-price purchase order (January 2026) for repairs, inspection, testing, and certification of the north light mast at the Aquatic Nuisance Species Dispersal Barrier, awarded as sole-source based on prior facility experience; a $36.6 thousand Total Small Business purchase order (February 2026) for administrative wing and bathroom remodeling including painting, floor and wall tile installation, and toilet partition installation; and a $43.7 thousand Total Small Business purchase order (April 2025) for procurement of fish barrier high mast lights.

Work spans three distinct NAICS categories — Industrial Building Construction, Commercial and Institutional Building Construction, and Electrical Contractors and Other Wiring Installation Contractors — with electrical maintenance and facility repair dominating the PSC profile. One award (valued at $42 thousand) reaches ultimate completion within the next twenty-four months, representing recompete exposure. The vendor has no subcontract footprint and no parent contract vehicle participation in the recent record. Activity is minimal and episodic: one award in 2025, two in 2026 year-to-date, with all dollars obligated against potential value. This represents early-stage or occasional supplier status with a single customer agency rather than an established federal prime contractor.
