Southdowns was appointed by AlignD JV (Jacobs, Ingerop, Rendel) to provide specialist support to the team responsible for the detailed design of the noise mitigation on the Colne Valley Viaduct.
Drawing on the company’s expertise in high speed railway noise and vibration gained during the detailed design of HS1, the scope of our input included the development of bespoke calculation methods for the reduction of noise from high speed trains on viaducts using innovative noise barrier designs comprising a combination of transparent panels and traditional noise barrier materials. The work was used to support the planning applications for the viaduct under Schedule 17 of the Act. Ongoing works include the iterative analysis of detailed design modifications including changes to the acoustical properties of treatments incorporated into the scheme designs, using novel finite element and boundary element techniques.
