Link Alliance Response to Matters Raised by the Community
This section outlines the type of complaint received and summarises the mitigation measures the Link Alliance utilised in response to the complaint.
Noise and Vibration The complaint register recorded 32 complaints in relation to noise and vibration impacts from the Aotea Construction Works. This was the most common complaint received. Noise and vibration complaints were mostly in relation to disruptive impacts from noisy construction activities impacting amenity and business, and the timing of these works (i.e. early morning and/or late evening). The range of mitigation measures Link Alliance utilised to resolve / respond to complaints are provided in Table 6 below. Table 6: Link Alliance response to noise and vibration complaints
Nature of complaint
18
Construction noise disrupting local businesses.
Vibration being felt within a neighbouring building.
Disruptive noise caused by use of the Hydro-vac machine.
Disruptive noise from construction activities occurring before 6am.
Summary of mitigation methods used The construction team ceased the disruptive noisy works. Noise levels were monitored to confirm compliance with levels outlined in the Project CNVDWP18. Site specific mitigation options were investigated. The stakeholder was contacted and advised about the mitigation measures deployed and informed of a timeline on when works will recommence and be completed. This enables the stakeholder to plan ahead. The affected stakeholder was contacted and informed about the type of construction occurring, why it was needed and expected duration. Noise and Vibration levels were monitored to confirm compliance with CNVDWP. Link Alliance met face to face with the impacted stakeholder to understand how impacts can be sufficiently (and practicably) mitigated. Use of the hydro-vac machine ceased upon receipt of the complaint. Noise levels were monitored to confirm compliance (or noncompliance) with the Project CNVDWP. Site specific mitigation options were investigated. The disruptive equipment was removed and replaced. The stakeholder was contacted and advised about the mitigation measures deployed and informed of a timeline on when they will recommence and be completed. Contacted the stakeholder to identify the cause of the disruptive noise. Briefed contractors and advised them of Link Alliance’s obligations. No noisy activities to occur prior to 7am.
A Construction Noise and Vibration Delivery Work Plan (CNVDWP) is required to be prepared for each stage of the Project works. Designation condition 31 and 33 outlines ‘Project Standards’ for construction noise and vibration that must be complied with. Site Specific plans are required where noise levels are anticipated to exceed Project Standards. Page 25 | 2019-2020 SIBD Annual Report - Aotea Station
