Environmental noise impact



The noise emission from a new development may potentially affect the nearby properties if noisy equipment such as mechanical plant and air conditioning plant is proposed or if outdoor areas for patron use are proposed to be part of the development. We provide noise assessment of the following developments:

  • Clubs, Hotels and Pubs: outdoor smoking, dining and gaming areas, mechanical plant, carparks;
  • Childcare Centres: outdoor and indoor playareas, air-conditioning plant, carparks;
  • Residential Developments: ventilation and air-conditioning plant, carparks;
  • Commercial Developments: workshops, mechanical and ventilation plant such as air exhaust and supply fans, chillers, cooling towers, truck and freight train movements, loading docks etc.


Traffic

Acoustic Reports are provided with recommendations for noise control, if necessary, to meet the following requirements:

  • Noise Guide for Local Government published by the NSW Environment Protection Authority (EPA);
  • NSW Industrial Noise Policy published by the EPA;
  • NSW Office of Liquor, Gaming and Racing (OLGR) requirements;
  • Council requirements such as their Conditions of Consent, LEP and DCP.

 

National construction code (NCC)



BCAThe Building Code of Australia (BCA) is now part of the National Construction Code (NCC). We will review your architectural and haudraulic drawings and provide recommendations for your development to comply with Part F5 "Sound Transmission and Insulation" of the BCA for Class 2 and 3 buildings (Apartment buildings) and Part 3.8.6.2 for Class 1 buildings (Townhouses).

The following building elements will be reviewed:

  • Common walls separating occupancy units to meet Rw + Ctr 50 and be of discontinuous construction where required;
  • Walls separating occupancy units from common areas to meet Rw 50;
  • Walls separating occupancy units from lift shafts and plant rooms to meet Rw 50 and be of discontinuous construction;
  • Floors separating occupancy units and from other areas to meet Rw + Ctr 50 and Lnw 62;
  • Sound insulation of services to meet Rw + Ctr 25 and 40 as required.

 

 

Occupational Noise Exposure



An occupational noise exposure is measured and assessed according to the following Standard:

  • Australian/New Zealand Standard AS/NZS 1269.1:2005 Occupational noise management Part 1 “Measurement and assessment of noise immission and exposure".

The calculated Normalised Daily Noise Exposure Level is assessed against the NSW Occupational Health and Safety Regulation 2001 which requires the following:

"... an employer must ensure that appropriate control measures are taken if a person is exposed to noise levels that exceed an 8-hour noise level equivalent of 85 dB(A), or peak at more than 140 dB(C)".
