This project will be constructed adjacent to the existing Salt Lake City Airport with no closures of the existing airport planned during the expected 8-year project timeframe. Due to poor soil conditions at the jobsite, structural LWC was specified to help reduce the number of pilings necessary in the sub-structure support system.

Claire Moore, HOK Engineers, also indicated seismic events were a concern and another reason structural LWC was chosen for the concrete on metal deck construction floor system as a means to reduce the dead load of the building.

Less Mass = Less Movement
