I405/SR22 Improvements and HOV Connector

atkinson

HAI provided vibration monitoring services during pile driving for construction of the I405/SR22 Improvements and HOV Connector in City of Seal Beach. The contractor drove concrete piles for construction of several abutments and bents. Caltrans was concerned with potential effects of pile driving-induced vibration on the nearby structures and required vibration monitoring and engineering evaluations to control vibration effects. The vibration-monitoring task included: (1) vibration monitoring plan; (2) documenting pre-construction defects; (3) measuring vibration levels during pile driving; and (4) if needed providing recommendations for using suitable construction techniques when high vibrations were noted.
