Proudly sponsored by AUCKLAND TOWN HALL The Auckland Town Hall, one of New Zealand’s premier heritage buildings, re-opened on 14 December 2011 after extensive strengthening. This historic building on Queen Street, in downtown Auckland, is known for its original and ongoing use for Council meeting and functions, as well as for its famed Great Hall and separate Concert Chamber. The Town Hall and its surrounding context is highly protected as a ‘Category A’ heritage place in the city’s District Plan. Its interior was extensively restored from 1994–1997 for NZ$33 million, partially because the unreinforced masonry structure did not meet earthquake standards, especially as a gathering place. Auckland City Council determined that the building should be strengthened as part of an overall restoration programme. Various techniques were pioneered to reinforce the structure without substantially changing the heritage character of the building. In 2007, the exterior underwent some restoration work. This presentation describes the standards of strengthening adopted, the analysis and the strengthening systems used.

Proudly sponsored by WATERVIEW TUNNEL The Waterview Connection is a motorway section through west/central Auckland. It connects State Highway 20 in the south at Mt Roskill to State Highway 16 in the west at Point Chevalier, and is a part of the Western Ring Route. The Waterview Connection is 4.5km long, 2.5km of which are in the NZTA form of twin tunnels. The Waterview Tunnel supersedes the Lyttelton NZTA Road Tunnel as New Zealand's longest road tunnels. By 2026, the link is Photo: Photo: expected to carry 83,000 vehicles a day. There are three lanes of traffic Photo: in each tunnel. This presentation will cover the fully tunnelled solution and procurement of an alliance to design, construct and maintain the project, with an overview of some of the key technical achievements.

Proudly sponsored by AUCKLAND HARBOUR BRIDGE The Auckland Harbour Bridge is an eight-lane box truss motorway bridge over the Waitematā Harbour in Auckland, New Zealand. It joins St Mary’s Bay on the Auckland city side with Northcote on the North Shore side. It is part of State Highway 1 and the Auckland Northern Motorway. The bridge is operated by the NZ Transport Agency. It is the second-longest road bridge in New Zealand, and the longest in the North Island. It is 1,020m long, with a main span of 243.8m, rising 43.27m above high water, allowing ships access to the deepwater wharf at the Chelsea Sugar Refinery. This wharf is one of the few west of the bridge, the proposed Te Atatu port not having been built. This presentation on Auckland’s lifeline bridge will cover the structure’s adaptation to changing demands, from construction of the original truss bridge in 1959 and addition of the extension bridges in 1969, through a programme of retrofit and strengthening works over the last two decades.
