WSM Pacific Siop, A Joint Venture

WSM Pacific Siop, A Joint Venture, a foreign-owned architectural and engineering firm headquartered in Honolulu, Hawaii, operates as a prime contractor delivering naval shipyard infrastructure design, engineering, seismic assessments, and facility modernization services exclusively to the Department of the Navy through a single-award $500 million IDIQ vehicle. The joint venture competes on full-and-open (no set-aside) basis and is a subsidiary of WSP USA Solutions Inc., a foreign-owned multinational infrastructure consulting firm.

Over the past five years, WSM Pacific Siop has captured 24 prime awards totaling $840.3 million in combined potential value, with $339.9 million obligated as of the source date. The customer concentration is absolute: the Naval Facilities Engineering Command accounts for 22 awards ($589.3 million potential value), the Department of the Navy accounts for 1 award ($249.8 million potential value, the largest single delivery order), and Navy Installations Command accounts for 1 award ($1.3 million potential value). All work flows through a single parent vehicle, Indefinite Delivery Contract N6274221D0001, a $500 million single-award IDIQ awarded September 7, 2021, and expiring September 6, 2026, against which WSM Pacific Siop has placed 23 task orders. The IDIQ scope encompasses preliminary design authorizations, advanced planning studies, final design packages, seismic vulnerability assessments, utility investigations, facility design studies, hazardous materials assessments, and infrastructure recapitalization planning across naval facilities under NAVFAC Pacific cognizance.

Representative work includes a $249.8 million delivery order (the largest in the portfolio) for P454 Multi-Mission Drydock initial studies and design phases at Silverdale, Washington, awarded February 2022 with completion targeted June 2028; a $16.7 million advanced planning study for Dry Dock 6 recapitalization awarded April 2024; a $12.2 million preliminary design authorization for CVN-78 aircraft carrier electrical upgrades at Bremerton, Washington, awarded August 2023 with completion extending to August 2030; a $11.9 million preliminary design authorization for the P-891 Shipyard Electrical Backbone project awarded August 2022; and multiple seismic vulnerability assessments and facility design orders ranging from $1 million to $9.4 million across Portsmouth Naval Shipyard, Norfolk Naval Shipyard, Yokosuka Ship Repair Facility (Japan), Naval Base Guam, Puget Sound Naval Shipyard, and Naval Base Kitsap. Work is performed at naval shipyards and facilities throughout the Pacific region, domestically at Portsmouth (Maine), Norfolk (Virginia), Bremerton (Washington), and Silverdale (Washington), and internationally at Yokosuka (Japan) and through host nation engineering work in Ottawa, Ontario, Canada.

Activity has accelerated sharply: 2 awards in 2022, 1 in 2023, 11 in 2024, 6 in 2025, and 2 in 2026 year to date. Eleven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $288.4 million and face recompete exposure as the parent IDIQ expires September 6, 2026. WSM Pacific Siop regularly subcontracts to WSP USA Solutions Inc. (its parent, providing program management and engineering services), Moffatt & Nichol (multi-mission drydock and dry dock engineering), Stantec Consulting Services Inc. (design development and engineering design), Power Engineers Inc. (electrical engineering), Wood Harbinger Inc. (electrical and mechanical design), and specialized providers in geotechnical, environmental, fire protection, cost estimation, and hazardous materials surveying. The joint venture's entire federal footprint is concentrated on naval infrastructure modernization under NAVFAC's Shipyard Infrastructure Optimization Program, with no diversification across civilian agencies or other defense components.
