Date: July -October 2015

Client: Calder Stewart Industries Ltd

Engineer: Engenium Ltd

PT Subcontractor: BBR Contech

Tyres 4 U specialised in the import and distribution of agricultural, industrial, truck, light truck and passenger tyres with branches in New Zealand, Australia and Papua New Guinea.

A new single level warehouse structure with attached office building was constructed by Calder Stewart Industries at 1 Treffers Road and intended to be used for tyre storage and administration.

The ground conditions at 3% CBR with 48kN racking post loads and 160kN forklift axle loads necessitated a 175mm thick post-tensioned slab on grade over the warehouse area of 4,000m². The PT floor was poured over two consecutive days with its central joint in permanent compression.
