The tunnel boring machine (TBM) on the Snells Algies wastewater pipeline and outfall project has recommenced its drive.
Dubbed ‘Piper’, the TBM is tunnelling for Watercare Services Limited in Auckland, New Zealand.
Over the weekend, Piper recommenced the drive from the intermediate shaft to the sea recovery trench.
Now, more than 750 m of the pending 2 km drive has been completed with cutting tool changes and other maintenance works being successfully undertaken in the shaft during less than favourable conditions.
McConnell Dowell wants to thank the Snells Algied project team for their hard work.
Even during the current level four lock down in New Zealand due to COVID-19, McConnell Dowell said the project team maintained world class safety standards while delivering the essential project.
