Transport asset management

How we use information about our assets to plan and prioritise how we look after them.

What is asset management?

The 2004 CSS Framework for Highway Asset Management definition is:

“Asset Management is a strategic approach that identifies the optimal allocation of resources for the management, operation, preservation and enhancement of the highway infrastructure to meet the needs of current and future customers.”

More simply, it is knowing all about our assets and using that information to plan and prioritise how we look after them. To do this efficiently and effectively and to provide best value for money we need to know:

  • What type of asset is it, for example, road, bridge, street light?
  • Where is the asset located?
  • Why is it there, how does it assist the network management and operation?
  • When will it need to be inspected, maintained or replaced?
  • How long will it last? How much will it cost to replace or repair, now and over its life?
  • Who will is responsible for it and who will be carrying out any necessary work?
