Building information modelling in the highways sector: major projects of the future

This paper assesses the current situation and ongoing developments with regards to the use of building information modelling (BIM) tools and processes in major projects by the UK Highways Agency. Using the M25 widening scheme as a case study, it explains the benefits of BIM within the sector as well as the current restrictions to its use. The potential for added benefits through the use of embedded information within BIM models is discussed, as well as the use of BIM tools in the handover process. The A556 improvement project is discussed as a possible demonstration project for these added benefits. Current challenges relating to the link between major project BIM tools and highways asset management are identified, and conclusions made as to what more can be done in this area to improve the whole-life management of highways assets.
