Credentials & honors

Commercial and public buildings make up most of what T W Clark Construction LLC builds, with some residential development alongside. Based in Spokane Valley, the general contractor works across the Inland Northwest on schools, office buildings, healthcare facilities and multifamily projects, plus structural upgrades and property expansions. Its public-works history runs back to 2004, nearly always as prime contractor, for school districts, state agencies and universities from Spokane to Wenatchee.

The agency list is long and specific: Spokane School District 81, Central Valley School District 356, the state Department of Enterprise Services, Social and Health Services, Eastern and Central Washington universities, the City of Spokane, the City of Wenatchee, and school districts in Pullman, Moses Lake, Othello and Bridgeport. Apprentices show up on that public work. Recent permits in Spokane Valley and unincorporated Spokane County cover new commercial buildings, engineered grading, demolition, commercial sewer connections, right-of-way work and a sign pylon. The state insures the crew, in the 31 to 50 range, for concrete foundations, wood-frame construction, interior finish carpentry, waterproofing, insulation and remodeling, along with project managers and superintendents. This is a firm built for institutional and developer-scale jobs: a district renovating a school, an owner adding onto or repositioning a commercial property, a developer putting up apartments or offices. A small kitchen remodel or a quick electrical or plumbing call sits outside that focus. The state has listed Thomas Clark and Clayton Linnell as principals since 1998 and Steven Sunleaf since 2017, and the company describes itself as family-owned and owner-led. Work tends to come through repeat clients and referrals more than advertising. On commercial and multifamily projects in Spokane Valley, the City of Spokane and unincorporated Spokane County, expect permits well beyond the building itself. Grading, sewer connections or abandonments, work in the public right-of-way, demolition and freestanding signs each carry their own permit and inspections, often from different offices. The general contractor should pull these and schedule the inspections, because inspectors hold the permit holder responsible and plan revisions have to be filed as the design changes. A contractor that handles this paperwork routinely keeps a project from stalling between trades.
