Freeport-McMoRan’s Buildings A and B in Tucson, Arizona support geological field operations and warehouse storage. Building A comprises approximately 150,000 square feet, with phased occupancy beginning in an approximately 30,000-square-foot area. Storage expansion requires a fire protection strategy that considers both the initial use and future growth.

Engineering Fire Protection, LLC developed assessment scopes addressing existing sprinkler protection, commodity classifications, rack arrangements, and water-supply requirements. The planned evaluations include review of system records, field conditions, and hydraulic performance to identify protection needs and potential upgrades for the two facilities.

EFP’s approach considers the anticipated full-building storage arrangement alongside the initial occupied phase. The consulting supports decisions about storage layouts and sprinkler improvements, helping the owner plan phased expansion with a clearer understanding of the applicable fire protection
