Western Partitions Inc. (WPI) is a privately held, union-affiliated specialty trade subcontractor founded in 1972 and headquartered in Lake Oswego, Oregon. The company delivers interior and exterior wall-and-ceiling construction services to general contractors and project owners across healthcare, education, commercial/office, mission-critical/data center, hospitality, public works, multi-family, and entertainment/sports facilities. Its branded WPI PreFab line of prefabricated exterior wall systems and its in-house BIM/Virtual Design & Construction capability are positioned as differentiators on complex, fast-schedule, and LEED-certified projects.

WPI's core services span light-gauge metal framing, load-bearing framing, drywall and gypsum board assemblies, acoustical ceilings and wall systems, sprayed fireproofing, firestopping, insulation, plastering and EIFS, commercial coatings, doors/frames/hardware, air and weather barriers, wood framing, claddings and building envelopes, raised access floors, and strut framing. WPI PreFab adds an off-site prefabrication and modularization capability that delivers single-source, warrantied building envelopes. Supporting technology includes BIM-driven 3D coordination, clash detection, and visualization. Together these offerings allow WPI to bid multi-scope wall-and-ceiling packages on large, complex projects.

The company operates through twelve regional offices across the western and midwestern United States (Oregon, Washington, Idaho, Nevada, Arizona, New Mexico, Utah, and Ohio) and engages directly with general contractors via competitive bidding on project-based contracts. Revenue is generated through one-time project subcontracts; pricing is not publicly disclosed.
