Carrying over 180,000 vehicles per day over the M6, a number of hairline cracks had been observed on the stiffeners of the College Road Bridge. The stiffeners were critically located at the mid-span of the bridge below the southbound section of the motorway.

This bridge carries six lanes of the M6 so it was vital to monitor its structural behaviour to ensure that maintenance plans could be put in place making sure it remained in good structural health. The structural monitoring solution required by Amey had to be quick, straightforward, and one that did not compromise on accuracy.
Our expert team designed a bespoke, real-time monitoring solution to investigate the dynamic load on two of the bridges ten box girders. The installation time of this monitoring system was minimal and was implemented without the use of destructive techniques that could potentially influence the structure.
The system consisted of three key elements:
One thousand samples a second were taken and sent directly to our Insite web portal. Following a seven day monitoring period, the data collected was then presented to the client for review.
Our engineered solutions range from standard designs to major projects, through to emergencies. We can also offer an end-to-end service from design and supply through to installation and removal.
We can work with you from initial concept temporary works design through to project completion, across all aspects of temporary works.
No matter how large or complex the project, we can help. It's what our major project teams do every day!
