Stantec-Aecom Siop JV

Stantec-Aecom Siop JV, a joint venture child entity of Stantec Inc., operates as a prime contractor delivering architect-engineer services and post-construction support to the Department of the Navy's Naval Facilities Engineering Command (NAVFAC), with no set-asides across its federal footprint. The venture is foreign-owned and for-profit, headquartered at 45 Network Drive, Floor 3, Burlington, Massachusetts, with a parent structure rooted in Mustang Acquisition Holdings Inc.

The vendor's federal portfolio is tightly concentrated in a single customer and contract vehicle. NAVFAC accounts for 100% of recent awards — four total, worth a combined $160 million in potential value — all issued as prime contracts with no sub-award activity. The core holding is a single-award Indefinite Delivery/Indefinite Quantity contract for the Shipyard Infrastructure Optimization Program Northeast, valued at $150 million with an ultimate completion date of January 13, 2031, awarded January 14, 2026. This IDC procures architect-engineer services supporting Naval Facilities Engineering Systems Command, Atlantic, including project documentation, design documents, surveys, cost estimates, program management, and criteria development focused on optimizing shipyard and waterfront infrastructure across the Northeast.

Three task orders have issued against this vehicle to date. A $10,000 delivery order on January 14, 2026, represented the minimum-guarantee opening; a $9.122 million delivery order on June 1, 2026, funded design in support of P1294 submarine berths extensions and upgrades at Portsmouth Naval Shipyard, Kittery, Maine, with performance at Portsmouth, Virginia and completion by August 31, 2027; and an $826,705 firm fixed-price delivery order on June 10, 2026, funded post-construction award services for Berth 13 structural repairs at Kittery, with completion by February 28, 2028. Only $10 million of the $160 million combined potential value has been obligated to date (6% of the ceiling). Three awards totaling $10 million face ultimate completion within the next twenty-four months and represent the near-term recompete exposure. Stantec's capability portfolio as reflected in this work centers on military engineering infrastructure planning, design, and facilities optimization for naval shipyard modernization.
