Scope of Work: During the construction of a new build, mixed-use development, the main contractor went into receivership, leaving the owners with a big problem. After initial checks had been carried out by the new contractor, it was found that significant areas of the building, did not have the required steel strengthening, in fact, it was found over 300 individual areas, at different locations, were affected.

Project Details
The Challenge
Provide a modern strengthening solution, that preserved the bridge’s historical integrity avoiding any significant structural alteration or profile change, whilst increasing the working capacity of the bridge to reflect modern day usage, increased traffic and size of vehicles.
The Solution
CFRP offers superior tensile strength being extremely lightweight and incredibly strong, making it an ideal material for historical restorations. Unlike traditional materials, CFRP can be applied without adding significant weight to the structure, which is crucial in preserving the bridge’s original design. Additionally, it allowed for targeted repairs that did not require extensive dismantling of the bridge, further safeguarding its historical appearance.
The Result
The application of CFRP not only increased the load-bearing capacity to 40t all loading, but also improved the bridge’s durability and resistance to fatigue and environmental degradation. Its high strength-to-weight ratio provided a substantial improvement in the load capacity while avoiding the need for bulky, visible reinforcements that could detract from the bridge’s historical character.
