Arch was tasked with an urgent response to the Groat 25 bridge site after severe flooding significantly eroded the embankment and retaining walls near the abutments. The flooding washed out the bridge approach, exposing critical structural elements such as piles and timber retaining systems. Because MoTI required rapid and effective flood protection, the team needed to prevent further damage and ensure the bridge’s long-term stability.
Our team quickly designed and implemented a robust retaining wall system. It provided soil retention and flood protection against future deluges and high-water events. The system included sheet piles anchored by steel cable tie-backs. These components withstood hydraulic forces and the impact of debris carried by the current.
We used advanced modeling to simulate worst-case scenarios. This process ensured the protection system could resist erosion and prevent failure under extreme conditions. The retaining wall system addressed the immediate crisis while offering a durable solution for the bridge’s ongoing safety and function.
