Trowbridge installation milestone keeps everyone safe

Looking after our lineside neighbours to safely complete significant milestone

Preserving through several challenges our colleagues working at Trowbridge, a single span overbridge in the town of Bradford-on-Avon, have reached a significant milestone following safely installing delivering programme critical works over a weekend possession. They finished on time and ensured minimal disruption to our lineside neighbours.

In just four days three main bridge girders and six crossing bracings were successfully installed onto the cast in-situ cill beam and ballast walls, despite tight tolerances. As a result of the team’s thorough and meticulous planning, the elements were accurately placed into position using a crane which had to be positioned to over sail the gardens of neighbouring properties alongside the railway line. This complex and challenging process involved securing several safety permits, and the implementation of rigorous safety protocols to ensure everyone was protected. Throughout the process all neighbours were kept regularly informed about the works and use of plant over their homes.

As the work site is extremely close to homes, the team made every effort to prevent disruption to local residents, and ensured plant and equipment was segregated when not in use. Throughout the daytime, plant was moved back from the footpath and fenced off to ensure people could continue to easily access their properties. For the following night-time works, fence lines were reinstated to allow space for works to continue.

To make the most of the line block on the railway line the team arranged for an ALO permit allowing for the pre-cast deck planks to be installed; which have been specifically designed to suit the skewed bridge angle. Without the team’s efficient use of time and proactive thinking the works would’ve required an additional possession.

Since, the main deck and stringcourse have been successfully cast, and the team are now progressing with the installation of the parapets, waterproofing and backfilling behind the structure.
