Harbor Construction Company, Inc.

Harbor Construction Company, Inc., operating as Harbor Construction Co Inc., is a Hampton, Virginia-based construction contractor that serves the federal government primarily as a subcontractor (73% of recent awards) on facility repair, renovation, and electrical modernization projects, with limited direct prime contracting activity (27% of awards). The vendor operates under total small-business set-asides on its prime work and generates the bulk of its federal revenue through sub-awards under two Indefinite Delivery Contracts with the Department of the Air Force.

Harbor Construction's customer base is heavily concentrated with a single customer. The Department of the Air Force Air Combat Command accounts for 53 of the vendor's 62 total awards (86% of award count) and $110 thousand of combined potential value across the portfolio, dominating both rankings. Additional Air Force sub-entities (Defense Finance and Accounting Service, general Air Force, and Air National Guard), the Department of Homeland Security US Coast Guard, the Department of the Army North Dakota Army National Guard, and US Special Operations Command round out a seven-agency customer set covering 95% of awards. This concentration masks a material revenue disparity: while Air Combat Command drives award volume, the Air Force Defense Finance and Accounting Service's single award carries $55 thousand in combined potential value—roughly half the Air Combat Command total despite representing only 1.6% of award count.

Harbor Construction places work under two primary Air Force Indefinite Delivery Contracts: FA480021D0008, supporting 41 task orders, and FA480018D0003, supporting 3 task orders. The vendor's prime work is illustrated by a $4,650 total small-business set-aside purchase order from US Special Operations Command for electrical services at Building 1503, Fort Eustis, Newport News, Virginia, with ultimate completion in February 2026. The overwhelming majority of Harbor Construction's revenue, however, comes from sub-award work under two recurring prime relationships. Midnight Sun-Centennial Kirratchiaq JV, LLC is the dominant prime, anchoring 38 of the 45 sub-awards since October 2022, with work spanning electrical infrastructure repair, HVAC systems, fire alarm installation, backup power systems, and facility renovations at Joint Base Langley-Eustis, Hampton, Virginia. Southeast Cherokee Construction, Inc. accounts for three sub-awards, including turnkey electrical and lightning protection scope on F-22 weather shelters and fire alarm system modernization at Air Combat Command facilities.

The vendor's capability profile centers on electrical contracting and facility renovation. Commercial and Institutional Building Construction dominates the NAICS taxonomy (45 awards), with Electrical Contractors and Other Wiring Installation (8 awards) and Security Systems Services (4 awards) as secondary categories. Work performed includes electrical system repair and replacement (transformers, switchgear, automatic transfer switches), fire alarm and mass-notification system installation, HVAC repair, facility lighting upgrades, ICD-705 intelligence-community-standard office conversions, backup power system repair, and general building renovation. Recent sub-work under Midnight Sun-Centennial Kirratchiaq spans repair of CRAC units, emergency communications centers, intelligence community directive surveys, and multiple electrical infrastructure projects at Langley Air Force Base and Fort Eustis.

Activity accelerated substantially in 2024 (22 awards) and 2025 (17 awards) from a baseline of 2–3 awards annually in 2022–2023, driven by expanded task order placement against the two Air Force IDIQs. The combined potential value across all 62 awards totals $211 thousand, but the vendor has obligated $9.6 million against this portfolio—a 4554% ratio indicating that actual invoiced work substantially exceeds the stated ceiling values in the source data, reflecting the nature of small, repetitive task orders under standing contracts where ceiling values do not capture total spend. Harbor Construction operates as a small business on set-aside solicitations and holds no government-wide acquisition contracts or parent vehicles of its own, relying on the Air Force Indefinite Delivery Contracts and prime contractor relationships for federal work access.
