An extensive group of engineers, consultants and other specialists were assembled to address the complex renovation/restoration needs of the historic Utah State Capitol. The project included very specific base isolation and seismic upgrade to the overall building, including the dome and rotunda. As part of the seismic upgrade, an elevated terrace was added to the building. Because the Utah State Capitol building is situated on a veritable seismic zone, the exterior stone and terra cotta were reinforced to seismic standards and repaired or replaced as needed. Additionally, the mechanical, electrical, data and communications systems were completely replaced. Clearly, this was a large undertaking overall, to say the least.

The interior restoration included replacement of skylights and reestablishment of original spaces, colors and ornamentation. The Capitol, which was divided into four restoration zones, was connected to the East-West buildings through a below podium tunnel.
