Black Diamond Lodge
City: Deer Valley
State: UT
Owner: Silver Lake Development
General Contractor: Bodell Construction
Project Description:
The Black Diamond Lodge, located slope side in Deer Valley, Utah required that a large portion of the mountain be supported to allow the construction of the new lodge. Because of the configuration of the building, the structural design for the building could not support the unbalanced lateral loads from the adjacent mountain.
Schnabel Foundation Company designed and constructed a permanent earth retention system to support the mountainside. The system included about 1000 lineal feet of tieback supported soldier beam wall and about 800 lineal feet of soil nail wall above the tieback wall.
The maximum combined height of the soil nail and tieback retaining walls was 80 feet. Because of the sloping hill side, up to six tiers of tiebacks were installed with tieback lengths of more than 100 feet. The wall facing was constructed using structural shotcrete wall attached to the soldier beams that was installed as the excavation progressed to subgrade.
