Stantec and AECOM Joint Venture awarded US$150 million single award contract to support US Navy Shipyard Infrastructure Optimization Program

BURLINGTON, MA (January 20, 2026) - Stantec, a global leader in sustainable design and engineering, together with AECOM has been selected been selected by Naval Facilities Engineering Systems Command (NAVFAC) to lead multidiscipline architect-engineer and consulting services as part of a five-year, US$150 million single award contract. The Stantec-AECOM Joint Venture work will directly support the US Navy's Shipyard Infrastructure Optimization Program (SIOP) focusing on the modernization of Portsmouth Naval Shipyard (PNSY) in Kittery, Maine.

"We are pleased to be selected for this important contract supporting NAVFAC's execution of the Shipyard Infrastructure Optimization Program," said Chris Williams, senior vice president, US Federal Programs at Stantec. "We look forward to applying our technical expertise to help modernize the Navy's shipyard infrastructure in support of fleet readiness."

"We are honored to partner with NAVFAC on this transformative effort to modernize the Navy's shipyard infrastructure," said Karl Jensen, executive vice president of AECOM's Governments business. "This award highlights AECOM's technical leadership and reinforces our role in delivering infrastructure that strengthens fleet readiness and operational resilience."

Updating four naval shipyards

SIOP is upgrading and modernizing the infrastructure at all four US public naval shipyards: Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY), Hawaii; Puget Sound Naval Shipyard and Intermediate Maintenance Facility (PSNS), Washington; Norfolk Naval Shipyard (NNSY), Virginia; and PNSY.

US Navy shipyards were originally designed and built in the 19th and 20th centuries. SIOP is a comprehensive, long-term recapitalization effort that is delivering integrated investments in infrastructure and industrial plant equipment at the Navy's four public shipyards, expanding shipyard capacity and optimizing shipyard configuration to meet the Navy's fleet maintenance requirements. Recapitalizing the shipyards' century-old infrastructure increases maintenance throughput and improves quality of service for the Navy's 37,000 shipyard employees.

Continued partnership with NAVFAC

Stantec has a longstanding relationship with NAVFAC and has supported SIOP programs and projects at all four naval shipyards. As part of a joint venture, Stantec is also currently contracted to support the SIOP Program at PHNSY and PSNS. Beyond SIOP, Stantec is currently providing services to the US Federal Government including the Department of Defense supporting the US Navy, US Air Force, and the US Army/US Army Corps of Engineers across the globe.

AECOM has supported the U.S. Navy's mission for nearly 100 years across a wide range of infrastructure and facilities projects. With a commitment to technical excellence and innovation, AECOM has provided master planning, architectural, engineering, environmental, and contingency response services on some of the US Navy's largest and most complex mission-critical projects. For SIOP, AECOM recently completed the Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility Area Development Plan.
