GEODesign provided all geotechnical and support of excavation (SOE) design and construction related services for the project. This initially included performing test borings and test pits to obtain critical information about soil, rock, and adjacent foundation conditions. We designed a foundation system of rock-socketed caissons and continuous flight auger-cast (CFA) piles bearing on bedrock. The designed SOE system included cantilevered soldier piles and soil-cement mixed walls below the groundwater.
The Solutions Unearthed
- The soil-cement mixed walls provided a value engineering alternative to more costly sheet piles and effectively eliminate vibrations, as compared to driving sheet piles.
- The cantilevered soldier piles eliminated the need for tiebacks or rakers, which resulted in faster foundation construction and reduced costs.
- The use of CFA piles provided a cost effective alternative to driven piles and effectively eliminated the vibrations, as compared to driving piles.
- Developed an SOE system close to very sensitive adjacent buildings that would not require underpinning or adverse conditions to the neighbors.
