This fibUK lecture will cover the design and construction challenges of the M25 J10 and M27 J10 projects.

The first presentation will cover the design and construction of modular bridge elements on the M25 Junction 10 project for National Highways. Presenters will highlight the early collaboration in the design stage to develop solutions utilising precast construction, the planning and implementation of modular bridge methodology on site, the challenges and successes and also how best practice and lessons learnt are being shared with other National Highways schemes.

The second presentation will focus on the M27 Junction 10 project for Hampshire County Council. Presenters will discuss the design stages, construction challenges and complex installation methodology associated with the implementation of a new dual carriageway underpass beneath a busy stretch of the M27 motorway.
