25 Demolition

Demolition: 3 /14 June 2016

The walls of both additional buildings (Outer building and Garage) had been built in unreinforced concrete using 40mm Oamaru stone as a brick veneer at the exterior.
These walls cannot be deconstructed and are to be removed by a demolition contractor.

Both additional buildings were stripped back to the bare stone and concrete structure.
Feature elements at the additional buildings, like the laundry facility (in Oamaru stone), the steel water tank, brass taps and the Garage door lintel were retrieved and put in storage.

The 20ft container on site was filled to the top and had become too heavy for any HIAB to be lifted.
After taking some of the timbers out, it was successfully lifted at the 3rd attempt by the largest HIAB of the South Island and transported to West Melton.

The only construction materials left over on site for the demolition contractor are unreinforced concrete and stone.
These materials can be dumped for free at Lyttelton Harbour, reducing the cost for demolition significantly.
Demolition started on Friday the 3rd of June and the site was cleared on Tuesday the 14th of June.
