Noise & Vibration Survey and Construction Impacts University of Adelaide Medical School

Introduction Assessment of noise and vibration impacts carried out in 3 stages: Baseline noise and vibration assessment within Animal House Assessment of noise and vibration due to different construction techniques within both the Medical School South and Medical School North Buildings (current)  Provision of guidelines for design and construction to minimise construction noise and vibration impacts (future).  

Test procedure Vibration Vibration field spectra were measured in the Z-axis (vertical, up/down). Measurement adjacent to the animal cages so as to measure vibration representative of the animal housing.   Noise A spatial average noise level was measured in the animal laboratory. Measurement times were taken such that the average noise levels were representative for the space.

Test procedure – construction survey A selection of construction activities were measured: 5 mm hammer drill 10 mm hammer drill 10 mm into 5mm hammer drill hole Jackhammer Sledgehammer Demo saw Coring Impact gas gun   Measurements of noise and vibration were undertaken directly above or below the construction on each floor of the building.

Construction comparison – Noise

Summary - Vibration Activity with greatest level of vibration were: Jackhammering Sledgehammering Drilling Coring Activity with least levels of vibration were: Demo sawing Cording Use of the gas gun

Summary - Noise Activity with highest noise levels were: Jackhammering Sledgehammering Drilling Activity with lowest levels of vibration were: Demo sawing Coring Use of the gas gun

Summary - General Use of jackhammer & sledgehammer should be avoided if possible Noise and vibration due to construction activity both have the potential to exceed relevant criteria and existing background levels. Use demolition saw and remove masonry wall sections in smaller sections. Place masonry walls in waste bins rather than drop from height. walls should be placed in waste bins rather than dropped from a height. Avoid use of hammer drills near the bio resources area. Acoustic mitigation is not considered to be practical as structure borne noise will transmit via walls and the floor. It is hence not practical to treat these surfaces with an additional acoustic barrier. Next Step Develop a detailed construction noise and vibration management strategy
