Project: Northern Quest Casino Expansion
Location: Airway Heights, Washington
The project included construction of an elevated casino, a 10-story hotel tower, a 6-level parking ramp, and a convenience store. ALLWEST provided geotechnical engineering which included soil borings, rock coring and field pressuremeter testing. Due to variability in overburden depth and quality of bedrock, we recommended a combination of drilled piers and spread footings for support of the structures.
ALLWEST also provided special inspections and materials testing for construction of the 6-level parking ramp and south casino addition which included drilled pier inspection, post-tension concrete testing, and inspection of reinforcement. We also provided special inspections for the 10-story hotel. Our services included soil density testing, reinforced concrete inspections, post-tensioned concrete inspection, shotcrete inspection, spray-applied fire proofing inspection, and non-destructive testing (ultrasonic testing of welds).
