World-first techniques at Tiwai Point Aluminium Smelter

This Smelting facility, based in Bluff at the bottom of New Zealand’s South Island, processes bauxite from Queensland, Australia to produce aluminium for use in New Zealand and abroad. In 1971, BCHF was responsible for designing the processing structures, which included 2,300 tonne of heavy structural steelwork and several crane runway beams. The use of prestressed concrete as a potroom structural material was a world first and, due to its success, was subsequently copied for use elsewhere.
