Snow King Resort Construction

April 28, 2015 by Carla Hansen

Heli Lift Concrete 009Nelson Engineering is performing the special inspections and testing services for the new Rafferty Snowlodge, Ski School Building, Chairlift and Mountain Coaster at Snow King Resort in Jackson, Wyoming.  Testing Services to be provided include; concrete testing, soil density testing, and construction oversight, to coordinate with the Surveying and Civil design provided.

Doppelmayr USA, Inc. of Salt Lake City, Utah uses the helicopter pictured here to fly the concrete to the charlift tower foundation sites. The concrete will be tested for compressive strength, which must meet 4,500 pounds per square inch (psi) in 28 days to meet the stringent specifications. Each truckload of concrete will be tested with four compressive strength specimens for each of the fifteen tower foundations. Three compressive strength specimens are being cast for each of the bottom and top terminals. The concrete specimens will be tested at 3, 4, 7 and 28 days to determine if the towers can be set on the foundation. If approximately 70% of the 28-day strength of 4,500 psi is met, the towers will be flown in and placed to prepare for cable installation. Testing the strength of the concrete is the only way to know if the lift will be safe and last for decades.
