Mountain West Debut

Salt Lake City, Utah

Redevelopment of the Salt Lake City International Airport has been under way for a couple of years now and is on track for completion in 2020. Malcolm is proud to have their newest regional office, Mountain West, contracted to provide ground improvement, shoring, excavation, and dewatering services for a new terminal building and concourse structure on this impressive $20 million design build project.

For this ground improvement scope, a seismic design is required to mitigate soil liquefaction. This will include more than 7,500 stone columns that are 3 feet in diameter and will range in depths from 29 to 44 feet. To meet the demands of the project schedule, Malcolm added two new stone column vibrator systems and three new duty cycle cranes to its already large equipment fleet, allowing four stone column machines to be in operation simultaneously. The cranes, two new Liebherr HS 8100s and a new Bauer MC64, are outfitted with state-of-the-art data acquisition controls, giving the Malcolm team all the information they need to maximize performance on their largest stone column installation to date.
