Stantec GS - AECOM Atlantic Joint Venture

Stantec GS - AECOM Atlantic Joint Venture, a foreign-owned large business, delivers environmental engineering, architectural services, and NEPA compliance support to the Department of the Navy and Marine Corps as a prime contractor across a single-award indefinite delivery/indefinite quantity (IDIQ) vehicle and related delivery orders, competing full and open without set-aside designations.

The joint venture is a strategic partnership between Cardno and AECOM, two global professional services firms, headquartered in Charlottesville, Virginia. Stantec GS Inc. is the parent entity. The joint venture operates exclusively as a prime contractor—all 140 awards in the recent portfolio carry prime designation with zero subcontract exposure. Capability focus centers on environmental assessments, environmental impact statements, NEPA documentation and pre-planning, cultural resources compliance and archaeological investigation, natural resources management, air quality permitting and emissions inventories, wetland permitting, shore protection infrastructure assessment, and related architectural-engineering technical support for naval and Marine Corps installations. Representative recent work includes a $1.07 million firm fixed-price delivery order from US Fleet Forces Command (August 2025) for an Environmental Impact Statement supporting F-35C aircraft home basing at Naval Air Station Oceana; a $834 thousand environmental assessment of the Industrial Production Complex at Marine Corps Air Station Cherry Point (April 2024); a $631 thousand delivery order for nearshore habitat assessment at Joint Expeditionary Base Little Creek, Norfolk (December 2025); and a $483 thousand environmental assessment supporting aircraft carrier homeporting at Naval Base Kitsap-Bangor (August 2024). The joint venture also holds subcontracting relationships with Hana Engineers & Consultants, Eurofins Lancaster Laboratories, and Marstel-Day LLC, a certified Women-Owned Small Business, supporting environmental testing and public engagement work.

Customer concentration is extreme and single-threaded. Naval Facilities Engineering Command (NAVFAC) dominates the portfolio with 68 awards valued at $146 million (85% of combined potential value and 49% of award count). The top five customers by both award count and potential value are identical, covering 91% of awards and 98% of dollars: NAVFAC leads, followed by the Marine Corps (26 awards, $9.7 million), US Fleet Forces Command (Atlantic) (15 awards, $7.6 million), Navy Installations Command (14 awards, $3.3 million), and Marine Corps Air Ground Combat Center (5 awards, $1.4 million). The joint venture has worked with 14 distinct federal agencies across recent awards, but Navy and Marine Corps activity represents the operating focus.

The entire prime footprint flows through two parent IDIQ vehicles. The flagship vehicle is the NAVFAC Atlantic $75 million single-award indefinite delivery/indefinite quantity contract (N6247023D0001), awarded November 10, 2022, extending through November 9, 2027, which carries 39 task orders worth $18.5 million combined potential value. An earlier related IDIQ (N6247016D9002) carries 99 task orders worth $27.4 million. Both vehicles were designed to provide flexible procurement for architectural-engineering services supporting ship homeporting and related operational issues across the Atlantic area of responsibility and, where required, worldwide. Task orders have executed at Naval Base Kitsap, Naval Air Station Whidbey Island, Norfolk Naval Shipyard, Naval Weapons Station Earle, Naval Weapons Station Yorktown, Naval Station Norfolk, Naval Air Station Lemoore, Naval Air Station Oceana, Marine Corps Base Hawaii, Camp Lejeune, and Camp Pendleton North, among other installations. All delivery orders employ firm fixed-price pricing and carry no set-aside designations.

Activity trajectory shows recent moderation. The joint venture issued four awards in 2026 (through March), eight in 2025, thirteen in 2024, thirteen in 2023, and two in 2022 — peaking at thirteen per year in 2023–2024 and declining to single digits in 2025–2026. Twenty-four awards with combined potential value $12.1 million face ultimate completion inside the next twenty-four months, creating recompete risk across that window. Combined potential value across all 140 awards stands at $171 million, with $45.4 million obligated to date (27% realization), indicating substantial unexercised ceiling under the parent IDIQs. Distinct customer agencies served number fourteen, but Navy and Marine Corps account for over 98% of potential value. NAICS concentration is complete: all 140 awards carry Engineering Services classification, with 91 coded to Architect and Engineering — General (Other) and 48 to Architect and Engineering — General (Landscaping, Interior Layout, and Designing). The portfolio reflects a vendor built to execute specialized environmental and compliance work for naval infrastructure — a capability set with narrow addressable market and heavy dependence on NAVFAC's ongoing demand for Atlantic-area ship homeporting and facility environmental support.
