Commuter Car Park and Interchange Program 13 Report Number 610.08297Mount Druitt Commuter Car Park29-Nov-2010Noise and Vibration Impact Assessment Revision 1Table 6Additional Mitigation Measures Matrix - Airborne Construction Noise(from TCA Construction Noise Strategy)Notes:1. The following abbreviations are used: Alternative accommodation (AA), Monitoring (M), Individual briefings (IB), Letterbox drops (LB), Project specific respite offer (RO), Phone calls (PC), Specific notifications (SN).2. For some types of construction activities (refer Appendix B of the TCA Construction Noise Strategy), a qualitativeassessment of the potential noise impacts can be undertaken in lieu of detailed noise modelling. For these activities,noise mitigation measures should be evaluated on the basis of the noise levels being noticeable, clearly audible,moderately intrusive or highly intrusive. The qualitative assessment should consider the type of equipment being used,the character of the noise emissions, time of day, the location of the nearest receivers and the noise sensitivity of thenearest receivers. Where a qualitative assessment is being undertaken, this will need to be approved by theEnvironmental Management Representative.During the detailed design stage, it is recommended that a site specific Construction Noise andVibration Management Plan is prepared, consistent with the requirements of the TCA ConstructionNoise Strategy and DECCW’s Interim Construction Noise Guideline.On the basis of the predicted noise levels presented in Section 4.2, the standard suite of noisemitigation measures is recommended to be applied during all construction scenarios. Further to this,3 m high hoardings are recommended along the western site boundary to mitigate the predicted noiseexceedances.The commercial property at 3 Mount Street has no windows or entrances facing the construction site.Despite its close proximity, it is therefore not envisaged to be very affected by the airborneconstruction noise.Although some exceedances are predicted at the TAFE educational facility, hoardings on the easternboundary of the development site have not been considered reasonable and feasible due to therequired height of any hoardings being excessive in order to achieve a significant improvement.Feedback from potentially affected receivers should be considered in selecting appropriate mitigationmeasures.Heggies Pty LtdA member of SLR Group
