SeaTac City Hall Feasibility

The City of SeaTac City Hall was first constructed in 1979 and underwent tenant improvements in 2002. In July 2020, ARC Architects was brought on board to explore the City’s future growth and potential for renovating the existing 3-story, 75,000-square foot building to last several decades and allow City staff to serve a growing population.

The design team assessed the existing conditions and provided recommendations for the City – including architectural, site, seismic, mechanical, electrical, telecommunications, building envelope, and hazardous materials. ARC Architects worked with departmental directors to develop a building program as well as strategies for workspace efficiencies that would allow City staff to serve a population size of 40,000. ARC Architects developed concept options based on projected growth and departmental adjacencies and provided associated costs for the recommended option. The final deliverable is a feasibility report outlining recommendations for next steps. The report includes a comprehensive building assessment, pre-design studies with floor plan options and concept renderings, and a cost analysis associated with the recommendations for the City.



SeaTac Maintenance Facility & Yard Feasibility

In conjunction with the feasibility study for the City of SeaTac City Hall, ARC Architects provided similar services for the existing City of SeaTac Public Works Maintenance Facility and Yard. Built in 2003, the existing site consists of four buildings and a maintenance yard. This study explored the City’s future growth and its impact on the maintenance yard and administrative workspaces by providing a comprehensive assessment, recommendations, and a cost analysis based on the architectural and site recommendations. These recommendations include an expansion to the administrative building to provide a new Training Center and accommodate a growing staff as well as yard recommendations that emphasize spatial organization, security, and modern standards.
