BWB Consulting played an integral role in expediting the accurate and effective surveying of a Victorian road bridge in Lichfield which crossed the West Coast Mainline, one of the UK's busiest rail routes. The structure dated back to 1820 and was to be demolished and replaced by a £4 million bridge that would provide access to a new industrial development and Lichfield Trent Valley station car park.
The planned demolition required a full site survey in order to plan the safe, efficient removal of the structure through temporary works design and was also used for the permanent works. The surveying works would normally require a track closure for health and safety reasons. However BWB utilised 3D laser scanning methods to collate and analyse the data and produce an accurate 3D model of the existing structure and trackside equipment without the need for track closures. This potentially saved 16 weeks on programme along with the associated costs and allowed the designs to progress.
The bridge was demolished on Christmas Day 2014 and the replacement structure officially opened in early 2016 having been delivered both on time and on budget.
