The density of high-rise building is increasing over recent years in urban city. Construction activities, particularly piling processes, D-wall excavation, are paid attention due to ground borne vibrations. The impact of construction-induced vibrations on existing buildings is discussed in the past and so on. However, the impact of some special source such as grab shocking the Metro Line 3 (Hanoi) hasnot beenmentioned in literature. This paper evaluates the potential effect of ground vibrations induced by grab shock on sensitive existing buildings through field experiences, alsothe analytical closed-form formulation of construction-induced vibrations on existing building in Hanoi is proposed. This formulation is applied to investigate the construction-induced vibrations on existing building in Metro Line 3 project. This application is useful to control the grab drop length as well as the distance of existing building to vibration source.
