Data standard

Collaboration between Waka Kotahi, The Road Efficiency Group (REG), local government and the transport sector is essential for the success of the AMDS programme to develop and deliver a national, shared standard for roading asset management.

How is the data standard being developed?

The success of the AMDS programme to develop and deliver a national, shared standard for roading asset management relies on a collaborative effort between Waka Kotahi, The Road Efficiency Group (REG) and the wider local government and transport sector.

Waka Kotahi is accelerating the development of the data standard to ensure sector benefits can be realised sooner. 

In collaboration with SMEs from maintenance contractors and professional services consultants that include; Fulton Hogan, Downer, Higgins, WSP, we are developing inventory assets and the management of the asset over its lifecycle (eg defects, conditions, observations and controls).

The standard is being released in assets groups by cycle for feedback from the sector. These cycles will produce outputs in usable formats (xls, xsd, pdf) to support the toolsets used by our sector partners.

How are we doing it?

• Waka Kotahi is working with transport sector SMEs to create a common language in asset categories.
• Developing inventory assets and the management of the asset over its lifecycle (eg defects, conditions, observations, controls) enabling key performance measures to be captured.
• The standard will be prototyped and tested within a mix of small – large sites representing Road Controlling Authorities (RCAs) and Network outcomes contracts (NOCs).
• Working with technology vendors to ensure their systems can function using the standard.
• The  published standard will be publicly available for Asset Management Solution (AMS) technology providers to use in their AMS systems.
• Understanding the type and level of support RCAs need to implement the standard, and working with RCA data experts, maintenance contractors and professional services to facilitate rollout of the standard.
• Roll out of the detailed implementation plan and support will start in Mid - 2022 and continue over four years.

Prototype – validating the standard

The AMDS programme is testing and validating the ability to implement the standard with the RCAs, maintenance contractors and professional services through our prototype activities. This will provide the information required to develop a repeatable model to implement in July 2022.

Prototype work has started with Marlborough Roads in collaboration with Fulton Hogan, HEB, WSP and Waka Kotahi. Prototype activities will overlap at appropriate times with planned sites with a mix of small to complete sites to ensure enough level of detail and impact is understood to move to the implementation phase with certainty. The prototype work is being developed in partnership with Company-X, to analyse and validate the data, and with thinkproject to develop the solution as the incumbent AMS technology provider.

Each file contains a comprehensive report of value lists and their corresponding values including a list of assets and their attributes, with attribute descriptors (properties) and version controls in CSV formats.

Please note the ZIP files below will be provided at a later time when the asset classes are developed.

The visualiser

The visualiser is a high-level process overview of the assets within the data standard. We invite you to play around to explore the asset types being proposed, their structures and relationships.
