Tennessee Governor's Residence
Maintenance, Renovation and Improvements
Nashville, TN

ICT provided mechanical, electrical, plumbing and fire protection engineering design for the Master Plan and the first of four phases of this project. The goal was to restore the Residence's architectural features and provide contemporary updates, while preserving the historic integrity of the house and property. ICT was careful to preserve the structure, shell, light fixtures and marble floors, in particular. All plumbing fixtures were replaced or refurbished. Some lavatories were refurbished.
