About the company
Oneill Contractors Inc., a women-owned small business based in Glenview, Illinois, delivers construction, facilities maintenance, and infrastructure services to federal agencies as a prime contractor across roofing, building systems, mechanical and electrical work, and waterfront infrastructure repair. The company is an Economically Disadvantaged Women-Owned Small Business (EDWOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), and SBA 8(a) Program Participant competing predominantly under set-aside vehicles, with 8(a) Sole Source and Competitive 8(a) designations characteristic of its prime portfolio.
The company's customer base concentrates heavily with maritime and military agencies. The Coast Guard dominates by dollar magnitude, accounting for 23 awards valued at $226.1 million combined potential value, followed by Naval Facilities Engineering Command (8 awards, $149.1 million) and Navy Installations Command (19 awards, $32.8 million). These three customers alone represent 92% of combined potential value across the portfolio. Veterans Affairs Veterans Integrated Service Network 12 places significant volume (21 awards) but lower dollar value ($8.6 million), while General Services Administration Regional offices (8 awards, $17.6 million) anchor federal building modernization work. The portfolio spans 33 distinct federal agencies, but customer concentration is pronounced: the top five customers account for 65% of all awards and 92% of potential value.
Oneill Contractors holds two major parent vehicles anchoring its federal delivery capability. A $55 million Coast Guard multiple-award IDIQ for civil engineering and construction support in Coast Guard District 9, awarded September 2024 under Total Small Business set-aside, has generated four delivery orders totaling $6.9 million to date, including a $2.85 million floating dock replacement at Station Chicago and a $3.57 million waterfront infrastructure repair project in the Northern Great Lakes. A $115 million Naval Facilities Engineering Command Competitive 8(a) multiple-award IDIQ for mechanical, electrical, plumbing, and fire protection projects at Naval Station Great Lakes and Naval Operational Support Centers, awarded June 2023 through May 2027, has issued approximately 15 task orders totaling $18 million, including a $2.78 million fire protection system upgrade (July 2025), a $1.998 million sewer repair at Forrestal Village (July 2025), a $2.42 million fan coil unit replacement (March 2025), and a $1.78 million exterior cladding replacement (July 2025). Oneill also holds the Coast Guard RMACC 2019 vehicle with 13 task orders valued at $3.7 million and several smaller agency-specific IDVs.
Recent representative work demonstrates scope breadth across federal facility types. Coast Guard awards include a $1.97 million fuel farm repair at Grand Haven (July 2026, ultimate completion March 2027), a $5.99 million wave attenuation system installation at USCG Sector Eastern Great Lakes in Buffalo (March 2026, extended to August 2026), and a $4.62 million waterfront major maintenance and repair in the Northern Great Lakes (January 2026, completion March 2027). GSA work spans a $3.14 million Garmatz Federal Building lower roof project in Baltimore (September 2025, 8(a) Sole Source), a $2.32 million supplemental cooling system at a Chicago federal building (January 2026), and a $1.81 million Philadelphia Custom House freight elevator renovation (September 2022, 8(a) Sole Source). VA work includes a $3.71 million potable water riser and isolation valve installation at Oscar G. Johnson VA Medical Center in Iron Mountain, Michigan (March 2022) and multiple roof and mechanical repairs at Hines VA facilities. Army Corps work includes a $2.9 million gate machinery modification at Chicago Lock (March 2023, 8(a) Sole Source).
Activity volume has been cyclical but sustained. Awards per year ran 9 in 2022, 13 in 2023, 15 in 2024, declining to 10 in 2025 and 7 through October 2026. Ten awards with combined potential value of $19.7 million face ultimate completion dates in the next twenty-four months, creating near-term recompete exposure and opportunity for competitors. The portfolio's combined potential value stands at $472.2 million against $106.8 million obligated (23% obligation rate), reflecting the substantial unexercised ceiling on the two large Navy and Coast Guard IDIQs and the multi-year nature of facility infrastructure contracts.
Service Contract Inventory data reveals modest SCI-reportable invoicing of $9.2 million across FY2022–FY2025, with FY2022 peak activity ($6.1 million across 9.2 FTEs) declining to FY2025 ($933 thousand across 1.5 FTEs). On SCI-captured service contracts, Oneill delivered median government-paid hourly rates around $280/hr, with senior labor pricing through $507/hr and entry-level work at $42/hr. Across SCI-reportable prime contracts, subcontractors accounted for an average of 11% of contractor hours, with 16 named subcontractors engaged, indicating Oneill performs the majority of work with its own teams. Oneill competes and performs exclusively as a prime; the portfolio contains no subcontract awards, positioning the company as a direct federal vendor rather than a feeder to larger primes.
