In March 2020, MHB Consultants carried out the design of the temporary works for Story Contracting to facilitate the essential bridge replacement at UB 163/104 Challoch Clumps in Dumfries & Galloway.

The single span bridge comprised two timber waybeams with trough girder deck.  The structure was demolished and replaced with Network Rail Standard U-Decks and the following temporary works designs were carried out;

  • Crane Outrigger Foundations
  • S&T Cable Supports
  • Abutment Saw Cuts
  • Abutment Stability
  • Abutment Edge Protection
