Karangahape Station’s sound of silence
At the bottom of Mercury Lane there is a great example emerging of how the Link Alliance wants to be the best neighbour possible.
Construction is well underway for a special shed half the size of a rugby field that, when finished, will help keep the noise down on this busy part of the project.
The shed sits above the temporary access shaft that’s being mined to help build the underground Karangahape Station.
The above photograph shows how much progress has been made building the shed.
When finished it will be clad with noise-reduction materials, allowing teams to work 24/7 underneath it – without disturbing the community nearby.
The access shaft has two main functions; one is to get workers and machinery into the underground station and the other is to remove the spoil dug out from the station concourse and platforms.
That spoil will be stored in the noise shed overnight before it is loaded it onto trucks for grading and to be used as construction fill offsite.
The shaft is now 17 metres deep and there are three more metres to go before it reaches the required depth.
The enclosure is being built over five weekends and is scheduled to be complete in September.
The Karangahape Station will be New Zealand’s deepest underground rail station at 32 metres and will sit between the Mt Eden and the Aotea stations.
The enclosure is temporary and will be removed at the end of the project.
