Introduction

The Maintenance Program covers the maintenance of all road, bridge and ancillary assets, road verges and reserves. Works include routine and periodic maintenance and reconstruction works where the primary reason is due to pavement failure. Some of the key projects and achievements delivered through the program are shown below.

Availability of Electrical Assets

Since 2008, one of the measures used in the context of reporting our progress against the outcome of achieving a well maintained road network has been the percentage availability of traffic signals, road lighting and emergency phones.

The measure was derived from contractual arrangements supporting the Traffic Control Infrastructure Contract (TCIC) and reports the percentage of time that the assets are fully operational. Since 2008, the results have ranged from 96.1% to 99.9% across all three asset classes showing little variation during this period.

In February 2013, the TCIC expired and services were subsumed within our Integrated Service Arrangement. As a result of issues in bedding down systems and processes under the new arrangements, there were issues with data validation from an audit perspective. At no time were actual levels of service in relation to the assets impacted. A new data entry framework and validation process has been established and full year reporting will commence as of July 2013.
