MAINTAINING AND MANAGING MOTORWAYS: DELIVERING REAL VALUE FOR MONEY AFTER SIX YEARS

摘要

The Challenge: To provide the ‘best value’ solution for the asset management and delivery of all maintenance and operational services for the Auckland motorway network. ‘Best value’ includes ensuring all assets are maintained within a specified Level of Service while maximising service life, and the operation of the network is optimised to ensure that customer satisfaction levels are maintained. The chosen solution was required to deliver ongoing sustainable savings over previous arrangements, and to prove that these savings were not consuming asset value in the short and longer term. The Response: The Auckland Motorway Alliance (the Alliance) was established in October 2008, for a period of ten years. It is essentially a virtual company comprising the New Zealand Transport Agency, a contractor and consultants bound by a commercial and performance mechanism to achieve significant advances in asset management and the delivery of motorway maintenance and operations. The Result: The paper presents the impressive results of the Alliance over its first six years, and how these have been achieved. Highlights include real savings of over 25%, resulting from innovative approaches to asset management and maintenance practices. These have extended the asset lives in a number of areas.
