Guidelines for Data Collection and Monitoring for Asset Management of New Zealand Road Bridges

March 2015

These Guidelines outline a process for data collection and monitoring for New Zealand road bridge asset management.

They discuss, firstly, the recent appraisals of the state-of-the-practice conducted by the New Zealand Office of Auditor General and the indicated need to adopt advanced approaches
to bridge asset management. The underlying relevant asset management principles are then briefly discussed.

The main part of the document describes the recommended process for data collection and monitoring road bridges. The process starts with developing baseline data. Following this, a bridge risk and criticality assessment is undertaken and based on the results, bridges are classified for the core, intermediate and advanced data collection regimes. Detailed recommendations concerning data collection techniques, inspection frequency and the types of data to collect for each regime are provided. Considerations regarding data storage and management are discussed.

Finally, a discussion about adapting the strategy to specific network needs is provided.
