Bernhard TME provided mechanical, electrical, plumbing, and fire protection design services as well as construction administration for a renovation and expansion of St. Thomas West Hospital in Nashville, TN. The multi-phase project included various infrastructure upgrades to the existing K Tower, central energy plant, and a new patient tower addition. The renovations include a renovated ICU with 44 private ICU rooms, support spaces, and new patient waiting areas.
The inclusion of reliable and energy efficient systems was a major project goal for the hospital with ASHRAE Standard 90.1 being a standard in the design requirements. The renovated K Tower and new patient tower include new air handling units with energy recovery units. The updated mechanical systems also include an expanded chilled water system with blended chilled water pumps to support the active and passive chilled beam systems in all support areas of the facility. The expansion also required upgrades to the steam system for the additional load needed, so a 500 HP boiler replaced a less powerful unit.
With the addition of the new patient tower, the existing electrical service did not have the capacity to service the expanded spaces. A new electrical system consisting of two separate services from the electric utility and a new main switchboard were installed next to the central energy plant. Additionally, new paralleling gear was added inside the central energy plant with additional generators to provide 100% backup power.
Strategic scheduling of the project took place to keep areas of the hospital operational, including the PACU, until the new patient tower was finished in 2016.
