The Sharnbrook Viaduct, a key component of the Midland Main Line, required refurbishment to address corrosion and accommodate increased freight capacity. The viaduct's dated rivet plate construction presented a significant challenge for conventional scaffolding methods. Lev3l was contacted by Alltask to collaborate in developing an efficient solution.

Our approach centred on a custom-designed bracket that relocates the suspension loads away from the outer flange edges of the rivet and plate I-sections. This bracket facilitated easy installation and construction of a suspended scaffold using LV78 aluminium lattice beams providing a safe working platform for bridge restoration personnel. 

Lev3l collaborated with the project’s design team, developing detailed engineering calculations and 3D models. Prototype brackets were fabricated and rigorously tested to European standards for certification. Following successful testing, fabrication drawings were produced, specifying high-quality manufacturing standards, and the brackets were delivered to site. Lev3l provided ongoing support throughout and after installation, including drone surveys with photographic and video documentation.
