Guthrie Robert Packer Hospital selected Z&F Construction in a competitive bid to provide a new cogen plant at their hospital. The project was completed as a design-build project. Z&F Construction was the prime contractor and Z&F Consulting was the lead design firm. The plant consisted of a 2WM gas engine and a 10,000 lb/hr dual chamber waste heat/gas boiler. Z&F Consulting also modified existing electrical switchgear to allow for connection to the generator.
