occupants of buildings. Table 1 presents a summary of vibration levels (mm/s) for
the assessment of human comfort, derived from AS 2670.2-1990. In terms of
overall ground vibration levels, Appendix C of Assessing Vibration: a technical
guideline recommends criteria for exposure to continuous vibration associated
with construction activities, specifically:
Place Day Night
Residence 0.2-0.4mm/s 0.14-0.28mm/s
Offices 0.4-0.8mm/s same
Workshops 0.8-1.6mm/s same
