The centerpiece of Deer Valley East Village is a 642,095-square-foot luxury complex that includes hotel rooms, private apartments, ballrooms, bars, restaurants and retail space.
The project was built on the side of a mountain with a network of tunnels under the surface that once belonged to a mine. Because not all mining voids were included in historical records, the building was designed to use a foundation system that could span potentially unknown voids underground. Hidden in plain sight, the parking structure functions as a foundation, designed to support the mountainside as it extends deep below the main entrance.
To build this way, crews made a 40-foot-deep cut up the mountainside. The cut was propped up with shotcrete and studs, and the foundation walls were built flush with this wall with blind side waterproofing and structured buttresses.
In more than 150,000 hours of work, with about 400 people on site during peak periods, the project team had no lost time incidents and an OSHA registration rate of 1.29. Special attention was paid to the crane loads, with crews strictly following all delivery protocols and constantly using the horns to alert everyone to the work being done on these pieces of equipment. Project leadership was extremely strict about properly tying and using toe boards when working at height. Workplace-specific safety orientations, regular workplace-wide safety walk-ins, and periodic and impromptu safety inspections were key to the safety messages.
