Vibration Monitoring – Batemans Bay Hospital

Vibration Monitoring – Batemans Bay Hospital

Nova Group Pacific recently completed a construction vibration monitoring program at a redevelopment site in Batemans Bay, NSW, located close to vibration-sensitive receptors including a nearby residential dwelling and the operating theatre at Batemans Bay Hospital.

Description of Services

The monitoring was undertaken during a compacted fill phase, a construction activity known to generate ground-borne vibration, particularly from heavy compaction equipment. Given the proximity of sensitive receivers, vibration monitoring was implemented to ensure construction activities remained within acceptable limits and did not pose a risk to building structures, occupants, or hospital operations.

Two vibration monitors were installed at strategic locations representing the nearest sensitive receptors. Monitoring was conducted over nine working days, in accordance with recognised standards including the NSW EPA Assessing Vibration: A Technical Guideline and German Standard DIN 4150-3.

The results showed that vibration levels were generally low and remained below the adopted criteria for the majority of the monitoring period. A small number of short-duration exceedances were recorded; however, these were either minor, intermittent, or attributable to external interference rather than construction activities. Importantly, no sustained exceedances associated with compaction works were identified.

Specific Challenges

Overall, the findings confirm that the construction activities monitored were unlikely to cause structural damage or unacceptable disturbance to nearby residential properties or hospital facilities. The monitoring program provided assurance that vibration impacts were effectively managed and that works were undertaken in line with best-practice environmental and community protection standards.
