Colby Co LLC

Colby Co LLC, a woman-owned small business headquartered in Portland, Maine, operates as a prime contractor delivering architectural and engineering services for facility infrastructure design, assessment, modernization, and construction support across federal installations in the northeastern United States and select other regions. The firm competes predominantly under total small business set-asides and partial small business set-aside vehicles, though a significant share of recent task orders are awarded without set-aside designation, reflecting Colby Co's established capacity to compete on a full-and-open basis.

Colby Co's capability portfolio centers on multidiscipline architect-engineer services: facility condition assessments, HVAC system upgrades and design, building envelope repairs and evaluations, infrastructure modernization planning, electrical and structural design services, geotechnical studies, water and utility infrastructure development, demolition and hazardous materials abatement design, fire safety and security system upgrades, and construction phase support including commissioning and post-construction award services. Representative work includes a $5.67 million delivery order from Naval Facilities Engineering Command for architectural-engineering services supporting the Next Generation Secure Submarine Platform program in Fleet, Virginia; a $3.16 million task order modification from Naval Facilities Engineering Command for logistics and space study services supporting CIA Zone 1 enabling development in Kittery, Maine; a $2.94 million delivery order from Naval Facilities Engineering Command for post-construction award services supporting the Dry Dock 2 Complex Project at Portsmouth Naval Shipyard in Kittery, Maine; and a $2.21 million delivery order from ENDIST New York for water infrastructure development at Fort Drum, New York, including installation of potable groundwater production wells and water main piping.

Customer concentration is heavily weighted toward defense and civilian agencies with installations in the Northeast. The Department of Homeland Security's US Coast Guard leads by combined potential value at $1.03 billion (31 awards), followed by the Department of the Air Force's Air National Guard at $280.4 million (14 awards) and Naval Facilities Engineering Command at $201.1 million (30 awards). By award count, GSA Public Buildings Service Region 1 leads with 90 awards valued at $58.9 million combined potential value, while Naval Sea Systems Command follows with 34 awards at $22.2 million. The top five customer agencies account for 93% of combined potential value, indicating significant concentration among Navy, Coast Guard, GSA civilian facilities, and Army Corps of Engineers customers.

Colby Co holds a robust portfolio of parent vehicle positions. The firm sits on a $1 billion multiple-award Coast Guard IDIQ for nationwide architect-engineer services (awarded June 2026, no set-aside); a $49.9 million total small business set-aside ENDIST New York engineering services contract through September 2030; a $40 million total small business set-aside GSA Public Buildings Service Region 1 A/E services IDIQ through June 2030; a $225 million partial small business set-aside Air National Guard vertical construction programs IDIQ (Air/Army National Guard Region 1 Vertical Construction Programs 2024–2029) through September 2030; a $90 million single-award total small business set-aside Naval Facilities Engineering Command multidiscipline architect-engineer contract for Naval Submarine Base New London and Naval Station Newport through May 2029; a $50 million partial small business set-aside Air National Guard A/E services IDIQ for Vertical Region 1 through March 2029; and a $30 million single-award Naval Facilities Engineering Command multidiscipline A/E contract through November 2026. Colby Co also holds a $24 million Army Corps of Engineers North Atlantic Division total small business set-aside IDIQ (July 2025–July 2030) and a $20 million Air Force Materiel Command multiple-award IDIQ for architect-engineer services through September 2029. Across these vehicles, the top five parent IDIQs place 176 task orders carrying approximately $74.2 million in combined potential value.

Activity has remained steady over the past five years, with 18 awards in 2022, 36 in 2023, 35 in 2024, 30 in 2025, and 4 recorded in 2026 through early June. Combined potential value across all 308 prime awards reaches $1.76 billion, with $118.8 million obligated (7% execution rate), reflecting the heavy reliance on multiple-award IDIQs with large ceilings. Twenty-eight awards totaling $19.4 million in combined potential value complete within the next twenty-four months, representing moderate recompete exposure concentrated in fiscal 2026 and early 2027.

Service Contract Inventory reporting captures minimal SCI-reportable activity—only $68 thousand in invoiced revenue across FY2022–FY2024 on four prime contracts. SCI coverage is sparse because Colby Co's work predominantly consists of architectural and engineering design and construction-phase services (delivery orders under fixed-price IDIQs), which fall outside SCI's reporting threshold or classification scope. The $47 thousand invoiced in FY2022 (0.2 FTEs) and $21 thousand in FY2023 (0.1 FTEs) represent a negligible fraction of the firm's federal revenue; SCI data does not capture the bulk of Colby Co's government work, and the vendor's true federal services revenue scales substantially higher than SCI figures alone reflect. Colby Co operates as a prime contractor on all awards in the source—no sub-award footprint is present—and delivers work with its own staff rather than through reliance on subcontractors.
