Garco Construction

Garco Construction is a Spokane, Washington general contractor with more than a century of work in the Inland Northwest, tracing its roots to 1908. The firm builds across education, healthcare, commercial and industrial sectors, offering general contracting, construction management and design-build delivery. Garco is the contractor on Central Washington University’s North Academic Complex in Ellensburg, an $80 million, four-story mass timber building heated and cooled by an aquifer-fed geothermal plant. That project, framed in cross-laminated timber sourced from local tribal nations, is one of the region’s more ambitious low-carbon academic builds. Garco has built a reputation for complex institutional work across Washington and the surrounding states.

Garco Construction is a Spokane general contractor with more than 400 team members and a footprint that, while centered on Washington, Oregon, and the broader Pacific Northwest, has extended to projects from Alaska to Louisiana to Michigan. The current construction company traces to 1978, when it was formed from the construction division of Garco Building Systems, and it delivers work as general contracting, preconstruction and construction management, design-build, heavy civil, and steel erection.

The project mix leans institutional and industrial, including schools, military installations, industrial plants, and commercial buildings, which is where the firm’s low-carbon and mass-timber work has drawn notice. Handling steel erection and heavy civil in-house lets Garco self-perform structural scopes on complex jobs rather than relying entirely on subcontractors, useful on the technically ambitious academic and industrial builds it takes on across the region.
