We have completed ground investigations required prior to construction starting.

The team undertook these investigations by drilling and probing the ground using geotechnical drill rigs and thrust machines to explore the ground up to 35m below the surface.

These geotechnical investigations allowed us to collect samples of soil and rock for testing at our partner laboratories, and to evaluate the strength and stiffness of the ground using in-place testing. At select locations after drilling is complete, instruments were installed into the ground to monitor variables like groundwater levels, temperature and ground movement.

The geotechnical investigation sites are shown on the map below.

All of our investigations were completed in compliance with the Environment Court decision and Resource Consent conditions, including the project noise standards. The equipment we used to investigate the ground, complete in situ testing, and collect samples may sometimes emit noise and cause vibration. We undertook noise and vibration monitoring periodically throughout the duration of the geotechnical investigations. All works were completed in compliance with the requirements of NZS 6803:1999 and applicable regulatory conditions.

A representative of Mana Whenua was on site and provide guidance if any archaeological discoveries are made.
