The Utah Third District Courthouse in Park City underwent a significant expansion to meet the growing judicial needs of Summit County in 2009. The addition provided new courtrooms, judges' chambers, clerk offices, and secure circulation areas to improve functionality, safety, and public access. Designed to integrate seamlessly with the existing courthouse, the expansion maintained architectural continuity while incorporating modern systems and materials.

Reaveley provided structural engineering services for the project, delivering a reinforced concrete and steel framing system tailored to meet current seismic safety standards, which is critical for the region's proximity to the Wasatch Fault. The addition supports the evolving demands of the judicial system while preserving the courthouse's civic presence in the Park City community.
