Snoqualmie Casino Expansion
Snoqualmie, WA
460,000 SF Mixed-Use | Project Timeline: December 2022 – Summer 2025
General Contractor: Skanska USA | Architect: Bergman Walls & Associates | Mech/Plumb Engineer: FEA Consulting Engineers.
MacDonald-Miller and our general contractor partner, Skanska, are thrilled to return to the Snoqualmie Casino – originally completed in 2008 – to more than triple its space. This expansion includes a 210-room hotel, a 2,000-person entertainment and convention center, a destination spa, expanded gaming floors, two signature restaurants, a valet parking garage, and all the amenities of a Las Vegas-style casino resort. This project reflects a significant investment by the Snoqualmie Tribe to enhance its economic and cultural influence in the Snoqualmie Valley.
MacMiller collaborated closely with design partners to navigate challenges, including coordination with out-of-state engineers working under different building codes. We focused on maintaining high-quality finishes while controlling costs and providing value-engineering opportunities.
Our crews installed over 26 miles of plumbing and mechanical piping and over 225 tons of sheet metal. Additionally, our Controls team integrated new systems with the Casino’s existing Honeywell controls, ensuring seamless operations.
At peak, our team comprised over 120 skilled tradespeople, including sheet metal, plumbing, pipe fitting, low-voltage, and insulation experts, alongside subcontractors VP Electric and Hudson Bay Insulation. The complex mechanical systems include 21 air handling units, 3 chillers, 3 boilers, 9 pumps, 324 fan coil units, 110 VAV units, and 40 fans. Plumbing installations include 8 water heaters, 347 water closets, 349 lavatories, and over 500 kitchen equipment connections. Our fabrication shop contributed 26,000 hours crafting custom ductwork, pipe racks, and equipment skids.
This project posed unique challenges, including hillside construction, extreme weather, integration with an existing 24/7 facility, and a compressed timeline. Despite these, our team worked tirelessly to ensure the project’s success. Thanks to the strength of our preconstruction, construction, and service teams, we are excited to continue our partnership with Snoqualmie Casino, including an upcoming replacement of their existing mechanical systems as part of a life-cycle upgrade to expand their mechanical capacity.
