Commuter Car Park and Interchange Program 12 Report Number 610.08297Mount Druitt Commuter Car Park29-Nov-2010Noise and Vibration Impact Assessment Revision 14.3 Comments on ResultsThe commercial property north of the development site has no window or entrance facing thedevelopment. The predicted construction noise levels in Table 5 represent the eastern and westernfacades of the building. Exceedances of the noise management levels of up to 16 dBA are predicted.The construction noise levels are predicted to exceed the noise management levels by up to 6 dBA atthe nearby Court House.Predicted noise levels at the nearby TAFE educational facility exceed the noise management levelsfor some scenarios, but not by more than 11 dBA.Exceedances of the noise management levels of up to 10 dBA are predicted for the residentialreceivers south of the railway corridor.4.4 Mitigation MeasuresTCA has prepared a “Construction Noise Strategy (Rail Projects)” which provides practical guidanceon how to minimise, to the fullest extent practicable, the impacts on the community from noise andvibration generated during the construction of rail projects (and related infrastructure) through theapplication of all feasible and reasonable mitigation measures. The Construction Noise Strategy isavailable for download on TCA’s website (www.tca.nsw.gov.au).The strategy includes a standard suite of noise and vibration management measures that are to beapplied on all projects and additional mitigation measures when construction noise or vibration ispredicted to exceed the project’s construction noise and vibration objectives.The standard suite of mitigation measures includes management measures such as communityconsultation, site inductions (with guidance on how to minimise noise and vibration) and thepreparation of site specific Construction Noise and Vibration Management Plans. The strategy alsoincludes several recommendations for reducing the source noise levels of construction equipment viagood planning and equipment selection.In many instances, it is not feasible to achieve the construction noise objectives and therefore the TCAConstruction Noise Strategy includes a list of additional noise mitigation measures which aim toreduce the potential noise impacts. These include measures ranging from letter-box drops and phonecalls to offers of alternative accommodation (for noise intensive night-time works). A summary of theadditional noise mitigation measures matrix is provided in Table 6. The purpose of letter box drops isto provide specific notification of the duration and timing of the construction activities so that residentsare informed about the proposed works ahead of time. The purpose of the monitoring is to validatethe construction noise predictions and confirm that the noise levels from individual equipment are notexcessive.Heggies Pty LtdA member of SLR Group
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
