Hamline Construction Inc.

Hamline Construction Inc., a Minnesota-based small business subchapter S corporation, is a prime contractor delivering repair, alteration, and new construction services to federal facilities across the upper Midwest as a total-small-business set-aside firm. The company operates exclusively as a prime contractor (100% of 391 awards) and competes predominantly under the total small business set-aside category across its federal footprint.

The vendor's customer concentration is dominated by two agencies anchoring 94% of combined potential value: the General Services Administration Public Buildings Service Region 5 (89 awards, $155.1 million) and the Department of the Air Force Air National Guard (79 awards, $82.3 million). GSA-PBS Region 5 issues repair and alteration task orders for federal courthouses, office buildings, and installations across six Midwestern states (Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin); the Air National Guard work focuses on facility maintenance, mechanical and HVAC upgrades, roof repairs, and infrastructure improvements at Minnesota Guard installations. Smaller customer agencies include the Department of the Air Force (64 awards, $6.9 million), the Department of the Air Force Reserve Command (10 awards, $6.8 million), and the Administrative Office of the U.S. Courts (26 awards, $4.7 million). The two largest customers also represent the two highest-volume award sources, indicating alignment between volume and dollars.

Hamline Construction holds two master IDIQ vehicles anchoring the prime portfolio. The GSA Region 5 Regional Construction IDIQ (awarded September 27, 2024, $50 million ceiling, small-business set-aside, through November 14, 2026) supports interior and exterior renovations, HVAC upgrades, electrical and plumbing work, and fire systems installation at federal facilities across the six-state region; 40 task orders carry $5.8 million combined potential value. The Air National Guard Construction MATOC (awarded February 10, 2023, $49 million ceiling, small-business set-aside, through February 9, 2028) supports construction, renovation, and repair for National Guard facilities statewide; 79 task orders carry $8 million combined potential value. Recent representative work includes chambers alterations at the Diana E. Murphy U.S. Courthouse in Minneapolis ($573,814, July 2025), fourth-floor renovation at the Bishop Henry Whipple Federal Building at Fort Snelling ($208,291, March 2026), roof replacement for Air National Guard building B614 ($2.4 million, September 2023), apron pavement repairs at the Minneapolis National Guard Base ($4.6 million, November 2023), and corrosion control room upgrades at Fort Snelling ($3.1 million, December 2023).

Activity has remained relatively stable—13 awards in 2022, 16 in 2023, 20 in 2024, declining to 10 in 2025 and 5 through June 2026—with modest annual volume reflecting the task-order cadence of the two master contracts. Nine awards with combined potential value of $4.9 million reach ultimate completion within the next twenty-four months and face recompete exposure. The vendor's work scope concentrates in Commercial and Institutional Building Construction (359 awards, NAICS 236220) and Other Building Equipment Contractors (4 awards, NAICS 238290), with supporting work in Highway and Civil Engineering. Service work spans repair and alteration of office buildings (138 awards), maintenance services (44 awards), and miscellaneous building maintenance and construction (37 awards combined).

SCI-reported invoiced revenue for FY2022–FY2024 totaled $6.9 million ($1.4 million FY2022, $1.9 million FY2023, $3.6 million FY2024), representing a fraction of the vendor's total federal revenue and reflecting only service contracts above the $150,000 reporting threshold. SCI data show zero FTE records across all three fiscal years, indicating that contracts captured in the SCI database were priced on a firm-fixed-price task-order basis rather than time-and-materials arrangements. The vendor delivers no subcontractor hours on SCI-reportable prime contracts (0% sub-hours share) and carries no named subcontractor relationships in the source data, indicating Hamline Construction builds its own direct delivery teams for all federal work. The company's core capability profile centers on mechanical and electrical building systems (HVAC, boiler, chiller, and heating upgrades), carpentry and interior finishes (drywall, painting, flooring, wall coverings), facility modernization (roof replacement, window and door installation, lighting upgrades), and specialized infrastructure work (elevator and fire-suppression-system modernization, power and data infrastructure). Hamline Construction has maintained federal contractor registration since 2003 and has established itself as the go-to regional contractor for GSA and Air National Guard capital improvement work in Minnesota and neighboring states.
