Question 1

Project Details

Accepted Answer

Innovative use of hold downs, as tested in the UC Canterbury PHD program, allowed a degree of repairability after a seismic event of the main connections. This provides robustness which ensures the building is quickly operational following a major event.

Question 2

Engineering

Accepted Answer

Cross laminated timber (CLT) is the primary structural material for the walls and floors, to achieve a low carbon footprint.

This L-shaped 6-storey building (1 concrete podium & 5 CLT floor and shear walls) has 450m2 per floor with an external 6-storey staircase lift shaft in CLT and Glulam.

Shear through contact (shear keys L1-3) and connections for efficiency and post fire stability.

Clad in DP955 metalcraft diamond-extruded aluminium
brown flash clad and lined everywhere due to acoustic flanking noise issue (we could have left some exposed).

The CLT in communal spaces such as the corridors and stairwell were coated in intumescent coating (zone arch products zone92).

The 965m3 of CLT used was sourced from PEFC certified, sustainable softwood plantations in Southern NSW, Australia. Timber used in the CLT is regrown in Australian softwood plantations in 90 minutes. This timber sequesters 753 tonnes of C02 through its growth.

The C02-eq stored in the 965 m3 of CLT supplied is the equivalent to the emissions from an individual taking 195 return flights from Auckland to London or saved by taking 446 cars off New Zealand roads for a year.
