RED HAWK CASINO
Shingle Springs, CA
Geosphere Consultants was selected to provide geotechnical consulting and investigation services for the establishment of the Red Hawk Casino. Located thirty minutes east of Sacramento on a hilltop in Shingle Springs, the $290 million dollar project was completed in 2009. Geosphere provided Engineering Geology, Geotechnical Engineering and Construction Observation/Materials Testing services for the completion of the design stages as well as through construction of the project.
The project included the construction of:
- Freeway Interchange on Hwy 50
- 8-story parking garage
- 3-Story 200,0000 Square Foot Casino
- Water Treatment Plant
- 2-Million Gallon Reservoir
- Retaining walls up to 100 feet high
This project was a technically complex project that included highly variable bedrock conditions, deep foundations, very high capacity shallow foundations, shoring and underpinning, and extensive paving. The parking garage structure was partially constructed on a 1:1 slope with 10-foot diameter drilled caisson embedded into rock supporting this structure. This foundation system was a cost effective yet challenging solution to a complex site layout. We provided extensive consulting and site investigation regarding a 100-foot high retaining wall that also was located adjacent to the Parking Garage. Extensive geologic mapping and observation of geologic conditions exposed during grading for the project, including the 2-Million Gallon Reservoir and the Water Treatment Plant, were performed by Geosphere.
The Geotechnical challenges involved in the project were as follows:
- Deep Foundation
- Soft Soil
- Slope Stability
