Problem
Client needed to excavate a 65′ deep hole on a 55,000 square foot lot on an urban university campus while providing minimal impact to the surrounding neighborhood.
Solution
- JKC worked directly with the earth retention design-build team to develop a streamlined, cost-effective diaphragm/slurry cut-off wall with a sequenced excavation process
- This process showcased our late-modeled, long reach equipment, allowing the mass excavation in thicker layers that maximized external tie-back and excavation production while minimizing internal bracing requirements.
Impact
- As a single earth retention and excavation team, the process streamlined communication, maximizing production and minimizing impact to the surrounding university community from trucking operations
- The proposed slurry wall acted as the final deep foundation, eliminating the need for traditional below grade cast-in-place concrete foundations
- The unique contract model eliminated scope gap concerns for the general contractor, allowing them to focus on the rest of the project
