There are continuing needs for seismic retrofitting of civil engineering structures, such as buildings and bridges. However, noise and vibration induced by retrofitting work disturb quiet environment in, for example, residential buildings and hospitals, which can delay retrofitting of such buildings. This report introduces theprogress of a collaborative research on noise and vibration control for anchor work in retrofitting of concrete structures. Vibration induced by boring work in a concrete block and concrete wall were measured to understand vibration characteristics. A vibration control device for boring work was developed and tested.
