Air New Zealand Nelson Hangar
Aurecon and Mainzeal Property and Construction Ltd
To construct the 80-by-60-metre hangar within Air New Zealand’s budget the roof structure was fabricated at ground level, then jacked up the building columns. Whilst this resulted in a heavy roof structure compared with a conventional light portal frame or truss system, the lower cost of simple welded beams and standard rafters reduced construction time and labour and crane costs. The relative ease of ensuring workplace safety more than offset the heavier weight. Detailed project planning was required.
The hangar has a joint-free post tensioned floor slab with a high performance coating. The hangar doors have telescopic mast rollers at the top two corners, with adequate length to accommodate roof truss deflections under the ultimate design wind uplift. This ensures the doors remain fully guided.
The hangar has pleasing aesthetic characteristics, and heating and ventilation are provided cost effectively. There is potential for thiscentral maintenance hub for Air New Zealand to attract business from international clients.
