Stantec and AECOM’s joint venture has secured a $150 million contract from Naval Facilities Engineering Systems Command (NAVFAC) Atlantic for architect-engineer services under the US Navy’s Shipyard Infrastructure Optimization Program (SIOP). The indefinite-delivery/indefinite-quantity (IDIQ), firm-fixed-price contract targets Portsmouth Naval Shipyard (PNSY) in Kittery, Maine.
Contract Specifics
This IDIQ contract has a $150 million ceiling over a base period plus four option years, with work set to be completed by January 2031. It received $10,000 in initial funding from fiscal 2024 military construction-design funds. Awarded competitively through sam.gov under number N62470-26-D-0001, it drew one bid.
Services include multidisciplinary architectural and engineering tasks, including planning, design, and technical studies for upgrades to dry docks, production buildings, utilities, and waterfront structures. These upgrades modernize aging facilities while keeping ship maintenance on track.
SIOP Overview
SIOP modernizes the Navy’s four public shipyards: Portsmouth (Maine), Norfolk (Virginia), Puget Sound (Washington), and Pearl Harbor (Hawaii). The initiative expands capacity, streamlines layouts, and prepares sites for nuclear-powered fleet maintenance.
Facilities date to the 19th and early 20th centuries and support 37,000 workers by boosting throughput and reliability. NAVFAC Atlantic in Norfolk, Virginia, manages the award.
Joint Venture Capabilities
The Stantec-AECOM SIOP JV, based in Burlington, Massachusetts, brings proven NAVFAC expertise. Stantec already aids SIOP across all four shipyards and holds active PNSY, Pearl Harbor, and Puget Sound contracts.
AECOM provides master planning, engineering, and environmental support for Navy work, including Pearl Harbor’s Area Development Plan. Stantec Senior VP Chris Williams stressed the team’s push for fleet readiness. AECOM Executive VP Karl Jensen emphasized operational resilience.
Project Significance
The contract bolsters shipyards to service advanced vessels like Virginia-class submarines. Early task orders ensure upgrades proceed without downtime. The JV’s win highlights its lead in Navy infrastructure delivery.
