Iconic Deloitte Building

Auckland CBD

1 Queen St, Auckland

SUMMARY

A Greenstar construction, set across 21 floors and offering 139 luxury hotel rooms alongside 14,000 m² of office space, also boasting the highest rooftop bar in Auckland. This ambitious refurbishment inserts a diverse range of activities into an existing structure. Te Kaha demonstrates how our existing built fabric can be transformed into an asset to be enjoyed by many.

THE PROJECT

A large existing commercial project with a new basement level being installed and connected to an existing adjoining building. Working with Kaizon and Sansom, we had to overcome a whole host of issues pertaining to water ingress before the Newton System 500 was installed. As a waterfront property built on reclaimed land, it was no surprise that a continual flow of water would be present when breaking out to create a new basement slab.

THE SPECIFICATION

Temporary pumps, injection works, and applied Type A negative side products were used to stop and manage the water entering the structure whilst the main works were carried out. Once under control, Sansom Limited installed through the basement the Newton System 500 Cavity drain membrane system. This incorporated the Newton Base drain channels around the periphery of the footprint with additional floor drain channels installed to assist in moving any free water quickly and efficiently to the sump chambers for instant removal. Newton 500 XPS Insulation was used, laid over the floor butting up to the drainage channels, providing valuable R values in accordance with H1. The Newton 508R cavity membrane was laid over the channels and insulation and sealed to complete the solution.
