Sustainability assessment of UK streetworks

Streetworks to repair buried pipes and cables use many different technologies and working methods. These are usually determined by the dual pressures of time, and economic costs. However, many other constraints should be imposed by the need to minimise both environmental costs and social costs, as these drivers, taken together, cover a range of other impacts. Given that the boundaries between the different categories of costs are often blurred, and different stakeholders hold different views on what to account for, the calculation is complex. This review paper focuses on the drivers for, and barriers to, the delivery of a balanced solution in the UK, and explores whether currently available methodologies are able effectively to assess different solutions to this complex problem. Following a review of the full range of potential impacts caused by streetworks in the UK, it concludes that a bespoke assessment framework needs to be developed for streetworks - application of general frameworks will not serve adequately.
