Plate compaction is often carried out on road and low-rise residential building construction sites to avoid the effects of differential settlements. The compaction activities generate ground vibrations, which may cause disturbance to people in close proximity and in extreme cases damage adjacent buildings if the vibrations are of a significant magnitude. Currently, in construction practice the minimum distance required between a plate compactor and an adjacent building is based on experience, rules of thumb and conservative practices. Some literature and guides are available for allowable ground vibration criteria, but little research has been carried out on ground vibrations generated by plate compactors. This study investigates ground vibrations generated by plate compactors. The vibrations are measured at various distances from the plate compactors on site to document the attenuation rate. These attenuation rates, and the allowable ground vibration criteria offered by various guides are used to determine the safe operating distances for structural safety. Discussions and comparisons on various guide criteria for structural safety are also given in this paper.
