J & B Builders Inc.

J & B Builders Inc., an SBA-certified women-owned small business headquartered in St. Charles, Illinois, delivers commercial and institutional construction, facility renovation, HVAC systems work, and infrastructure repairs to federal defense and civilian agencies as a prime contractor across 169 awards totaling $336.8 million in combined potential value. The vendor competes predominantly under small-business set-asides — Total Small Business and Woman-Owned Small Business designations recur across the prime portfolio — though a significant share of recent delivery orders carry no set-aside designation.

J & B Builders' customer concentration is heavily skewed to the Department of Defense and its components. The top five funding agencies account for 76% of awards by count and 79% by combined potential value, led by the Department of the Air Force Air Mobility Command (22 awards, $121.4 million combined potential value) and the Department of the Air Force Defense Finance and Accounting Service (20 awards, $47.4 million). The Air National Guard ranks third by volume (47 awards, $45.1 million) but lower in dollar concentration, reflecting a portfolio of smaller delivery orders. The Department of the Army Illinois Army National Guard (18 awards, $5.6 million) and the Department of the Army Indiana Army National Guard (2 awards, $30 million) round out the active set, with the Indiana National Guard win representing a single high-value outlier. Civilian work includes one General Services Administration award (masonry restoration at the Melvin Price Federal Building, East St. Louis, $642,905) and one Department of Agriculture Regional award (building envelope repairs at the National Center for Agricultural Utilization Research, $5.1 million).

Capability portfolio centers on military facility construction and repair. Representative work includes a $2.02 million Air Force delivery order for roof repairs and improvements at a Milwaukee facility (Feb 2025), a $4.32 million Air Force definitive contract for alteration of a 40,000-square-foot aircraft shelter at Truax Field Air National Guard Base, Madison, Wisconsin (Aug 2022), a $773,114 Air Mobility Command delivery order for log jam removal and creek repairs at Silver Creek, Scott Air Force Base (Oct 2023), a $513,200 Air National Guard purchase order for storm drain inlet repairs at Peoria Air National Guard Base (Aug 2025), and a $5.1 million USDA Agricultural Research Service definitive contract for building exterior envelope repairs, window replacement, and associated work at NCAUR in Peoria (Sept 2023). Work spans HVAC unit replacement and repair, roof restoration, building envelope and masonry work, stormwater infrastructure, facility door and window replacement, utility infrastructure upgrades, aircraft parking apron repair, and site preparation. The vendor's NAICS concentration is Commercial and Institutional Building Construction (130 awards), with subordinate work in Highway, Street, and Bridge Construction (12 awards), Plumbing, Heating, and Air-Conditioning Contractors (6 awards), and Site Preparation Contractors (6 awards).

Vehicle position anchors to Army construction and Air Force facility IDIQs. J & B Builders holds or has held seats on the Army Construction IDIQ 2010-2015 (43 task orders, $8.3 million combined potential value), Indefinite Delivery Contract W912J217D4001 (18 task orders, $8.8 million), W912J222D4002 (11 task orders, $8.4 million), and W50S7T20D0002 (11 task orders, $2.7 million). On the Air Force side, the vendor places work under Indefinite Delivery Contract FA440718D0015 (10 task orders, $2.5 million). The vendor also holds a single-award $25 million Indefinite Delivery Contract with the Wisconsin National Guard awarded Sept 2022 through Aug 2027 for maintenance, repair, construction, and design-build services at National Guard facilities including General Mitchell International Airport in Milwaukee, Truax Field in Madison, and Volk Field in Camp Douglas, and a single-award $7 million Blanket Purchase Agreement with USDA Region 9 - Eastern Region for bunker demolition services awarded Sept 2023 through Sept 2028 (one task order issued, $1.59 million).

Activity has remained relatively steady year over year — seven awards in 2022 through nine in 2025 — with only one award recorded in 2026 to date (the June 2026 Air Force chiller replacement). The recompete cliff is minimal: only two awards (combined potential value $1 million) reach ultimate completion within the next twenty-four months, signaling low near-term exposure to competitive recompete. Obligated dollars total $66.9 million, representing 20% of combined potential value, indicating work remains in execution phase across most of the portfolio.

On federal service contracts captured in Service Contract Inventory, SCI-reported invoiced revenue reached $4 million in FY2025 across 1.7 full-time equivalents, up from $2.2 million in FY2024 across 0.6 FTEs. Government-paid hourly rates on SCI-reportable prime contracts run a median of $414.76 per hour, with 10th percentile pricing at $339.38 per hour and 90th percentile at $490.15 per hour. Across SCI-reportable prime contracts, subcontractors account for an average of 25% of total contractor hours, with three named subcontractors reported across the SCI records. J & B Builders operates exclusively as a prime contractor: 100% of the vendor's 169 awards are prime contracts or IDVs, with zero sub-award activity in the source data.

The vendor has held federal awards dating to 2010, with SAM.gov registration confirmed since 2009. Recent trajectory shows a shift from smaller, routine delivery orders ($7,571 to $500,000 range) toward larger definitive contracts and multi-year IDIQ vehicles in the $2–5 million range, particularly within Air Force and Air National Guard facility modernization and repair portfolios.
