Network Scaffolding provided access to undertake vital strengthening works to the viaduct, situated in South East Scotland in 2015.
The biggest quandary came in the unique design of the scaffold. The Viaduct was at a zero rated loading capacity meaning the conventional suspended scaffold was not feasible.
The solution was to utilise the 1.5m deep Apollo beams spanning 26m over the SSSI River, supported off heavy duty towers, with 450mm beams sat on top to provide a 1.5kN/M2 working platform 2m below the bridge soffit without enabling further stress to the structure.
The scaffold was then fully encapsulated to allow the essential strengthening works to take place.
Thankfully due to months of planning and analysis, the conundrums were met with effective, controlled solutions to allow to project to complete within time and budget.
