We know what condition it is in.

The Asset Management Rainbow…

We know what

we have got.We know what it is worth.

We know what condition

it should be in.

We know our long

term forward programme.

We know that we have

a BMS to manage the data.

We know that we will be able to secure the

necessary funding.

We know the optimal way

to close the performance gap.

Implementation

Implementation• There is a statutory obligation on highway

authorities to maintain the public highway (Highways Act, 1980)

• Safe for Use requires a highway structure to be managed in such a way that it does not pose an unacceptable risk to public safety (31).

• Milestone One – March 2006.

• Fit for Purpose requires a highway structure to be managed in such a way that it remains available for use by traffic permitted for the route (32).

• Milestone Two – March 2007.

Implementation

Good Management Practice (17)

• Customer focused asset management approach.

• Deliver required Levels of Service.

• Minimise whole life costs.

• Make optimum use of resources.

• Provide a sustainable programme of work

• Milestone Three – March 2008 to March 2010

Review of Progress

Review of Progress

• CSS Bridge Management System Survey

• CSS Code of Practice Implementation Survey.

We comply with Milestone One, with only a few gaps left to be filled. We partially comply with Milestone Two. We do not comply with Milestone Three.

No idea until I study Code of Practice. (Not familiar with this document as yet!)

We have a lot of what is recommended in place at the moment. We are just completing our first attempt at a transportation asset management plan, and we will now begin to look at the areas where we have gaps in our data and management systems e.g. valuation, prediction models, whole life costing and some aspects of performance monitoring. We are currently working with SERCO regarding abnormal load vetting using ESDAL and so will be interested to see how their system develops in 2006.

Research Opportunities

Research Opportunities• Establish a regime for the asset valuation of

highway structures in accordance with the CSS document

• Develop and implement components of the AM Regime needed to deliver the Advanced AM Planning process for highway structures

• Develop and implement lifecycle plans for all groups and sub-groups of highway structures
