Background

The Asset Management Initiative (AMI) was introduced as TfL recognised that borough maintenance budgets are commonly stretched and were not addressing general maintenance issues along the LCN+ and in locations where changes to the highway layout were not required.

The pilot AMI commenced in 2004/05 involving 13 London Boroughs.  The process involved a survey of the all LCN+ Links in each of the boroughs, and the results were then sent back to the boroughs to produce an estimate for the repair of the identified faults.  Funding was then made available through the LCN+ variation process and approved by TfL.
 
Following the pilots, the AMI was rolled out to the remaining boroughs. To date, over £3.2M has been allocated to 23 boroughs, with the majority of the remaining 10 planning AMI works in 2007/08.

Continuation of the AMI

In 2006/07, a second round of surveys commenced to assess the changes in the maintenance needs following the first round of surveys and to pick up additional faults which may have developed since the original surveys were carried out.  Analysis of the data from the second round of surveys showed that the number of faults had been reduced significantly since the maintenance work had been completed.  The data from these surveys is being made available to each borough so that they can apply for further funding as necessary.

Process

The diagram below briefly describes the process undertaken so far.

Results so Far

A review into the performance of the process so far has produced encouraging results.  Boroughs have been requested to take a cost-effective approach and some have used funding as an incentive to bring forward other planned maintenance works which allowed the entire road width to be treated.  The following results look briefly at five boroughs, which have been the subject of a second survey (Bromley, Camden, Hammersmith and Fulham, Islington and Southwark).

Figure 1 (below) shows the total number of repairs made by each borough, including those on the old alignment that are no longer part of the Network, and gives an indication of the most common fault types.

Figure 2 (below) looks at those faults on the current alignment and shows the total number of repairs carried out in each borough (including the ones on the old alignment) and how many faults remain to be repaired by each borough.  The faults remaining have been separated into two categories, firstly, those faults remaining from the first survey that were not repaired and then those in the last column for each borough identify faults that are “new”.  The new faults include those that have been identified on the new alignment(s) and those that lie on the unchanged sections of the alignment though have developed since the original surveys.
