Controlled Blasting was used to facilitate excavation of large amounts of bedrock for construction of the Pier W2 foundation of the Self Anchored Suspension bridge on Yerba Buena Island. This bridge is part of the new San Francisco-Oakland Bay Bridge (East Span).
Two volumes of rock were to be excavated, each 60 by 60 by 60 feet in size. EMI led the coordination effort for a blasting demonstration program to test the viability of controlled blasting of the rock.
The program included instrumentation to measure ground vibration, water overpressure, and air noise level for various charge weights. The demonstration showed that controlled blasting was effective for excavation, and that environmental disturbance could be mitigated. The actual excavations for the Pier W2 foundations were later performed using controlled blasting, without adverse effects on nearby structures or wildlife.
