The iconic, Category 1 heritage-listed Tui Brewery tower has been sympathetically upgraded to 100 per cent of the National Building Standard. This skilful piece of work, developed in collaboration with client, engineers and Heritage New Zealand, required the delivery of a complex seismic upgrade that included base isolation, sliders, minimal steel-bracing and post-tension cables. The restoration methodology has minimised the impact on the building fabric and maintained layers of history for future celebration.
