US construction company Granite has signed a $34 million contract to implement seismic improvements to the Oakland International Airport Perimeter Dike.
The infrastructure project is designed to protect the airport runway from water intrusion from the adjacent San Francisco Bay.
The project aims to use 62,295 cubic yards (47,628 cubic metres) of a cement deep soil mixing construction solution (CDSM) to enhance the seismic resilience of 4,200 linear feet (1.3 kilometres) of the dike.
Granite said that the technique would strengthen the levee wall soils and mitigate the risk of dike failure in the event of a strong seismic event.
Geotechnical specialist Keller North America has performed the CDSM scope.
Other work includes clearing and grubbing, constructing temporary work pads, installing wetlands protections, protecting existing fuel lines, and installing 2,100 cubic yards (1,606 cubic metres) of rip rap revetment and aggregate base surfacing to restore the existing perimeter road.
Brent Fogg, Granite vice president of regional operations said, “The technical challenges and restricted access of this project will require meticulous logistical planning to ensure an efficient and safe workflow and zero impact on Airport Operations.”
The project is expected to begin in early 2025 and be completed the third quarter of 2026.
