45 – 53 Boston Rd (J.A. Russell) SSCNMP C69.1 Introduction This Site Specific Construction Noise Management Plan (SSCNMP) is for 45 – 53 Boston Rd. A SSCNMP is required because construction is predicted to exceed the standards in CRL designation conditions 31. This SSCNMP has been prepared in accordance with CRL designation condition 37 and is Appendix C69 of the Mt Eden Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP). It is a supplementary document that builds on the CNV DWP, and therefore directly references relevant sections of the CNV DWP to avoid repetition. The objective of this SSCNMP is to detail the best practicable option(s) (BPO) to avoid, remedy or mitigate the identified adverse effects from noise exceedances at 45 – 53 Boston Rd. This SSCNMP has been prepared for the Link Alliance and forms part of the Construction Environmental Management Plan (CEMP) for the Mt Eden Station Main Works. It builds on the SSCNMP previously prepared and implemented for the Mt Eden Stormwater Realignment Works.
C69.2 Engagement Mt Eden C6 Stormwater Realignment Works Graeme Inglis (MBJV) and Craig Fitzgerald (Marshall Day Acoustics) met with Warren Goodall (J. A. Russell Branch Manager) and their architect Malcolm Ewart (MOAI) on 16 April 2018. The matters discussed in both meetings included an overview of the project, general project programme, sheet piling, overview of the CNV DWP and this SSCNMP, communications triggers and protocol, building layout and identification of noise and vibration sensitive spaces. The eastern most building on this site is approximately 4-5m from the closest edge of the GPT2 site and was the focus of the noise and vibration effects. The modern masonry building was built in approximately 2004. The street level basement includes a pump and generator room beyond which is car parking. The first-floor level includes a showroom on the street façade, behind which is office and retail areas. The second level is open plan and enclosed office spaces. Potential vibration from sheet piling activities was the primary focus of the discussions. The vibration levels are predicted to comply with the cosmetic building damage thresholds for a commercial building. However, occupants would likely find the noise and vibration levels uncomfortable and potentially disconcerting. Mr Goodall advised that the buildings were fully occupied during weekdays, but only retail areas in other buildings were occupied on Saturdays. Therefore, Mr Inglis and Mr Goodall considered that timing the sheet piling activities on Saturdays would avoid noise and vibration related amenity effects. Furthermore, and despite predicted compliance with the cosmetic building damage vibration limits, a pre construction building condition survey would be offered to provide confidence that any attributable damage would be captured and enable it to be remedied by MBJV accordingly. Lastly, vibration monitoring would be undertaken to verify the predictions and enable the implementation of adaptive management measures if required.
