Revisions to Legislation such as the UK New Roads and Streetworks Act (Section 74- charges for unreasonably prolonged streetworks and 74a - pilot lane rental trials) are increasing unit costs for Utilities. The International Society for
Trenchless Technology (ISTT) has also received expressions of concern throughout Europe on social costs associated with works that are greater than the value of work being undertaken.
Other potential increases to streetworks costs include: traffic congestion charging; cases relating to the Human Rights Act; medical claims from no-win-no fee solicitors for persons injured by streetworks; potential class action disruption to businesses or claims from increased pollution associated with streetworks.
The research addressed these issues and has:
- Identified indirect streetworks costs that Utilities will have to fund. This provides date for asset management plans
- Developed a whole life costing model to assess indirect costs and risks associated with different rehabilitation options
- Used the model to examine revised definitions of critical sewers and enable cost effective sewer rehabilitation decisions
- Provided a Best Practice Document to implement efficient streetworks.
ISTT and affiliated societies have provided a European, American and International perspective on lane rental and social costs and WRc has worked with Ian Vickerage of Manchester University (UMIST) who has conducted extensive social costs research.
- Minimise the costs and risks associated with streetworks
- Incorporate robust streetworks costs into Asset Management Plans
- Ability to assess indirect costs and risks of rehabilitation options (including critical sewers)
- Efficient streetworks organisation with the Best Practice Document.
