Renewing and replacing assets

1.10 Renewing and replacing assets

Transport asset risk management is undertaken using a rolling programme of condition assessments to inform renewals decisions.

Condition is the main indicator used to understand if and how transport assets are deteriorating. The DCC's asset management planning is increasingly focused on asset condition coupled with age profiles and risk assessments. From time to time however, fiscal constraints need to be considered in asset renewal strategies.

1.10.1 Principal options and implications of replacing and renewing ageing infrastructure.

The option that the DCC has decided to take in bold.

Renewals delivery continues at current rates, with no plans to increase internal or external delivery capacity

Transport renewaIs continue to be prioritised in accordance with known asset condition and performance within existing budgets, however ageing assets mean risk to service levels increase.

The value of renewals required versus those undertaken will continue for 30 years, based on the increasing age of assets and inflation.

The value of renewals undertaken is expected to flatline in the long-term.

The design and delivery of renewals will become more effective in maintaining service levels over the longer term, as internal and external capacity to deliver is increased.

Renewals delivery is increased over time as internal and external capacity to deliver is increased.

As above, however renewals delivery is increased in years 1-3 to reflect asset replacement (based on age and condition rating) needs. From years 3-10 renewals value will be gradually increased year by year.

The renewals programme will be more effective in reducing maintenance and operating expenditure and reducing the risk of deteriorating service levels.

Non-critical issues, or those that affect a limited number of customers, can be addressed more

quickly than they otherwise would.

As above, however, infrastructure risk profiles will be reduced as delivery of the renewals programme begins to outpace the rate at which asset age and condition deteriorate.

Operations and maintenance costs can be reduced, and issues will become less prevalent.

Renewals delivery is accelerated in the early years of the plan, increased overall

As above, but with significant budget moved to years 1-2 to address priority renewals.

Deferred or removed projects to be completed.

The renewals programme will be most effective in reducing maintenance and expenditure.

The value of renewals undertaken is expected to flatline at a much faster rate than in other options.
