Colby Co LLC

Colby Co LLC, a woman-owned small business based in Portland, Maine, operates as an architectural and engineering services prime contractor to federal agencies, delivering facility infrastructure design, assessment, modernization, and construction support across the northeastern United States and subordinate operations nationwide. The firm competes predominantly full-and-open across defense and civilian agencies, with a secondary footprint on total small business set-asides, particularly under Navy and Army Corps of Engineers vehicles.

The vendor's capability portfolio centers on multidiscipline architectural and engineering services spanning facility condition assessments, HVAC system design and replacement, building envelope repair and evaluation, infrastructure modernization planning, electrical and structural design, geotechnical studies, water and utility infrastructure development, hazardous materials abatement design, demolition support, fire safety and security system upgrades, and construction-phase administration. Representative work includes a $5.9 million total small business set-aside delivery order from Naval Facilities Engineering Command for full architectural and engineering services supporting the Next Generation Secure Submarine Platform program at Norfolk, Virginia (April 2024); a $5.2 million total small business set-aside from NAVFAC for architectural and engineering services at Naval Undersea Warfare Center divisions P079 and P1430 in Newport, Rhode Island (April 2023); and a $2.2 million delivery order from ENDIST New York for potable groundwater production wells, monitoring wells, and high-density polyethylene water main construction at Fort Drum, New York (January 2023). Recent 2026 activity includes a $500 million partial small business set-aside multiple-award MATOC from ENDIST Baltimore for multidiscipline architect-engineer services supporting the Baltimore District and North Atlantic Division (July 2026) and a $1 billion multiple-award Coast Guard nationwide IDIQ for professional architect-engineering services covering the entire United States and territories (June 2026).

Customer concentration reflects split strength across defense and civilian agencies. The top five funding agencies account for 68% of awards: the Coast Guard (32 awards, $1.03 billion combined potential value, dominated by the new $1 billion nationwide IDIQ), General Services Administration Public Buildings Service Region 1 (90 awards, $58.9 million), Naval Facilities Engineering Command (31 awards, $205.2 million), Naval Sea Systems Command (34 awards, $22.2 million), and Army Corps of Engineers Engineering District New England (28 awards, $43.6 million). When ranked by potential value, the Coast Guard and Army Corps of Engineers Baltimore dominate dollars ($1.53 billion combined from just four awards, primarily the two 2026 IDIQs), while GSA Region 1 places the most individual task orders.

The vendor holds twelve active parent indefinite-delivery vehicles aggregating over $2.26 billion in combined potential value. The largest are the newly awarded Coast Guard nationwide IDIQ ($1 billion ceiling through June 1, 2036), Army Corps of Engineers Baltimore MATOC ($500 million through July 30, 2031), Air National Guard Vertical Construction Program IDIQ ($225 million through September 30, 2030), Naval Facilities Engineering Command multidiscipline contract for Newport and Groton area ($90 million through May 12, 2029), GSA Public Buildings Service Region 1 multiple-award architecture ($40 million through June 30, 2030), ENDIST New York engineering services ($49.9 million through September 30, 2030), Army Corps of Engineers North Atlantic Division engineering design ($24 million through July 24, 2030), Air Force Materiel Command A/E services ($20 million through September 29, 2029), and Air National Guard Vertical Region 1 services ($50 million through March 28, 2029). The Naval Facilities Engineering Command $30 million single-award total small business set-aside contract (established November 2021, through November 2, 2026) and Coast Guard District 1 $9.975 million multiple-award IDIQ (total small business set-aside through October 24, 2026) represent the oldest active vehicles; the former has generated sustained activity including nine task orders valued at approximately $6.1 million since May 2024.

The vendor has received 316 total awards spanning design, engineering studies, construction administration, feasibility assessments, and infrastructure modernization across civilian and defense missions. Activity has remained stable in the recent period at roughly 30–36 awards annually (2023–2025), with 12 awards recorded in 2026 year-to-date (as of July 31, 2026). Nineteen awards totaling $24.1 million in combined potential value reach ultimate completion within the next twenty-four months, creating recompete opportunity for competitors and near-term refresh demand for Colby Co on maturing vehicles.

Service Contract Inventory reporting shows minimal staffing for SCI-reportable work: $240 thousand in prime invoiced revenue across FY2022–FY2025, with 0.6 FTEs recorded in FY2025 (the most active year captured). Government-paid hourly rates on SCI contracts ranged from a 10th-percentile floor of $122.68 per hour to a 90th-percentile ceiling of $271.03 per hour, with median pricing around $150.03 per hour. SCI captures only federal service contracts above $150,000; the vast majority of Colby Co's federal work—evidenced by 316 awards and $2.26 billion in combined potential value—consists of architecture and engineering delivery orders, goods, and construction work outside the SCI scope. The vendor operates with zero subcontractor hours on SCI-reported prime contracts, delivering its own staff to engagements.

Colby Co LLC executes 100% of recent awards as prime contractor with no recorded sub-award footprint, a posture that reflects its position as a direct contractor to federal agencies rather than a feeder to larger primes. The firm's entire federal footprint sits on its own prime vehicle seats and task orders flowing from them, positioning it as a standalone service provider rather than a subcontractor network node. The woman-owned small business designation recurs across approximately 40% of active awards, particularly on Navy, Army, and GSA total small business set-aside IDIQs, while the remaining 60% are full-and-open competitive.
