Bridge asset management at Auckland Transport

Auckland is the most populous city in New Zealand. To keep Auckland moving, Auckland Transport (AT) manages the local transportation network with 1260 bridges and major culverts. With the growth of the city, this number keeps increasing.Asset Management of these bridges at AT is facing various challenges from increasing transportation demands, fast changing environment and climate change et al. All those demands require us to review the strategies of how to maintain a sustainable transport network within a limited budget.This paper gives an overview of the bridges that support Auckland’s transport network regarding the current asset management strategy and practice. Risk management is at the heart of AT’s bridge asset management. The consequence-and-probability calculation supports the framework of the bridge asset strategy. It covers the prioritisation, decision making, short-term and long-term planning and environmental protection.As the good practice in bridge asset management, the adaption of new technology and safety-first principle are also discussed. However, bridge management and maintenance are always facing new challenges, this paper identifies some challenges AT may face in the future.
