A visit to the Central Interceptor May Road site
Shaun King recently visited the Central Interceptor May Road site, where he went down a 75m shaft and ventured a short distance into the 4.5m wide tunnel. Shaun said it was great to see the tunnel in person after so much hard work has gone into the surface sites.
The Central Interceptor is the largest wastewater project in New Zealand, with the tunnel running for 16.2km from Herne Bay to Māngere. To deliver the project, there are 17 construction sites along the tunnel route.
Marshall Day Acoustics, led by Mat Cottle, first became involved in the Central Interceptor project in 2011 when they were engaged by Watercare to assess construction and operational noise effects. This involved ambient noise level monitoring, computer noise modelling, preparation of the noise impact assessment, input to the formulation of resource consent and designation conditions, and presentation of expert evidence at the hearing.
Since 2019, the MDA team has worked closely with the Ghella Abergeldie JV to predict and assess construction noise and vibration, prepare Construction Noise and Vibration Management Plans and Activity-Specific Noise Management Plans, assist with neighbour consultation, construction noise and vibration monitoring, and train the Environmental team on noise and vibration monitoring.
The MDA team, consisting of Mat Cottle, Shaun King, and Reuben Jelleyman, has enjoyed working on such an interesting project with Watercare and Ghella Abergeldie JV and appreciates the opportunity to visit the tunnel.
