Affinity Health System

St. Elizabeth Hospital - Central Utility Plant

Appleton, WI

Boldt has a history of successful projects for St. Elizabeth Hospital, Affinity Health System and the healthcare industry as a whole, but working on a utility plant isn’t a typical “health care” project. Boldt was chosen to upgrade St. Elizabeth Hospital’s central utility plant because of their experience with industrial and power projects.

The main focus of the project was to rebuild the hospital’s 14,600 sq. ft., three-story central utility plant and energy systems. The project also included a vertical expansion over the existing plant, which required careful planning as the building remained operational during construction.

Improvements to the plant’s systems include installation of new boilers that use exhaust to pre-heat its feed water, reverse osmosis water treatment system and energy efficient centrifugal chiller, cooling towers, pumps and generators.

The upgraded plant is now better equipped to serve the campus, but also saves the hospital money through efficiency. New equipment installed in the plant, which replaced the more than 50-year-old previous parts, yields an estimated 25 to 30 percent reduction in energy use and also requires less maintenance work.

Boldt used its Integrated Lean Project Delivery® (ILPD) process to reduce project costs while adding value at the same time. Early collaboration with the hospital allowed Boldt to suggest modifications in scope and schedule, which reduced both up-front and long-term operational costs.
