Recently awarded physical works contracts are inclusive of the majority of road corridor assets in the maintenance requirements. With the greater risk being shifted onto the physical works contractors, the contractor is required to have a better understanding of each asset type to be maintained and the inherent risk associated with each. A process and system has been developed, to make it easier to understand these risks, which consists of: 1. identifying network issue locations, including high-risk areas; 2. determining suitable asset condition parameters, based on agreed levels of service, for each asset type; 3. undertaking a visual rating for each asset type; 4. documenting field work into database and spatially represent ratings; 5. analysing ratings and risks to network condition and meeting the levels of service; 6. prioritising and completing the maintenance work required. The outputs from the system are summarised as: 1. reports on the performance of the road network for the client; 2. reports on the change in assessed condition between surveys completed; 3. tools to assist the supplier in prioritising and programming maintenance work. The system and process are described in detail in the paper, and the benefits identified. (a) For the covering entry of this conference, please see ITRD abstract no. E217099.
