Hamline Construction Inc.

Hamline Construction Inc., a Minnesota-based small business operating exclusively as a prime contractor, delivers repair, alteration, and new construction services for federal facilities across the upper Midwest under total small business set-asides, with a diversified portfolio spanning 35 distinct customer agencies and concentrated strength in GSA Region 5 and Air National Guard facility programs.

Hamline Construction is a for-profit Subchapter S corporation headquartered in Roseville, Minnesota, competing predominantly under the total small business set-aside category. The company's federal footprint is anchored in NAICS 236220 (Commercial and Institutional Building Construction), with additional activity in building equipment contracting and civil engineering. All 399 awards in the source are prime contracts; the vendor does not operate as a subcontractor to other primes, and across SCI-reportable prime contracts, no subcontractor hours are reported—Hamline delivers its own labor.

Hamline's capability portfolio centers on interior and exterior renovations, HVAC upgrades, mechanical and electrical systems work, plumbing, fire suppression systems, and specialized facility improvements at federal buildings. Recent representative work includes a $4.6 million definitive Air National Guard contract (awarded November 2023) for apron pavement repair at Minneapolis National Guard Base; a $3.1 million definitive Air National Guard contract (awarded December 2023) for corrosion control room reconfiguration and fire/life safety upgrades at Fort Snelling; a $2.0 million delivery order (awarded March 2022) for senior judges chamber and learning center renovation at the Warren E. Burger Federal Building in St. Paul; and a $619,349 definitive contract (awarded August 2024) for passenger elevator modernization at the Devitt U.S. Courthouse in Fergus Falls. The vendor delivers across placement types including definitive contracts, delivery orders against IDIQs, and standalone purchase orders, priced predominantly on firm fixed-price terms.

Customer concentration is high and tilted toward civilian federal property management. The top five customer agencies account for 70% of award count. GSA Public Buildings Service Region 5 leads decisively at 89 awards and $155.2 million combined potential value, followed by the Department of the Air Force Air National Guard at 81 awards and $82.6 million. The Department of the Air Force (non-ANG), Administrative Office of the U.S. Courts, and GSA Public Buildings Service (corporate level) round out the active set. The two customer rankings align tightly—GSA Region 5 dominates both volume and dollars—reflecting consistent small-order activity rather than a divergence between frequent and high-value customers.

Hamline holds two significant parent vehicles anchoring its federal work. The GSA Region 5 Regional Construction IDIQ, awarded September 27, 2024, carries a $50 million ceiling, multiple-award structure, and total small business set-aside designation; it supports repair and alterations services across six Midwestern states (Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin) through November 14, 2026. The Air National Guard multiple-award task order contract (MATOC), awarded February 10, 2023, carries a $49 million ceiling and runs through February 9, 2028. Both vehicles are multiple-award, permitting task orders to any eligible contractor; Hamline places orders regularly under both. The source names five additional parent IDIQs with Army Corps of Engineers and Defense Logistics Agency issuing task orders, though none carries the scale or activity volume of the GSA and ANG vehicles.

Activity has remained steady over the past five years, with 13 awards in 2022, 16 in 2023, 20 in 2024, declining to 10 in 2025, and 13 through September 2026. Only 13 awards face completion inside the next twenty-four months with combined potential value of $6.3 million—modest recompete exposure. The combined potential value across all 399 awards is $273.7 million, with $89.6 million obligated (33% of potential), indicating substantial unfunded pipeline.

SCI reporting captures only 20 records across FY2022–FY2025, reflecting the fact that most of Hamline's awards fall below the $150,000 reporting threshold or are goods/construction orders excluded from SCI scope. Across SCI-reportable prime contracts, invoiced revenue totaled $8.1 million (FY2022: $1.4 million; FY2023: $1.9 million; FY2024: $3.6 million; FY2025: $1.2 million). Government-paid hourly rates across prime contracts derived from SCI invoiced dollars ran uniformly at a median of $6,350.67/hr, reflecting the cost-reimbursable or T&M structure of those specific service contracts. FTE data across the same SCI records shows 0.0 FTEs reported, a data-capture artifact where SCI reports contract-level labor dollars without hour-level personnel detail; the actual workforce engaged on federal work is larger and not quantified in the SCI subset. Hamline self-performed all SCI-reportable prime contract work with no named subcontractor hours.

Hamline Construction's positioning as a 100% prime contractor with no subcontractor engagement makes it a direct competitor to other GSA Region 5 and ANG IDIQ awardees on small facility repair and alteration work, not a supplier to larger primes. The company's deep customer relationships with GSA Region 5 (89 awards) and the Air National Guard (81 awards) reflect sustained task-order demand rather than recompete dependency—the two vehicles run through late 2026 and February 2028, respectively, providing continuity for near-term pipeline.
