Yellowstone National Park Old Faithful Inn

The Old Faithful Inn, located in Yellowstone National Park, is a popular lodging facility that combines historic and modern characteristics. Coffman provided fire protection engineering services including replacing the existing dry system for 90,000 sf of guestrooms renovation in the west wing, and 61,000 sf in the east wing.

Due to the corrosive nature of the water, Coffman designed a new, double interlock pre-action fire sprinkler system, with nitrogen, to help guard against corrosion by an accidental discharge of water vapor. This new system further protects the historic hotel and mitigates fire risk while avoiding visual distraction from the structure’s natural, historic, beauty.
