The survey is part of a feasibility study that has already shown that the work would be technically feasible but very disruptive. Roger Tym & Partners is part of the international team that has been assembled to carry out the study by lead consultant WA Fairhurst of Glasgow. Also included are Cowi Consult, Amman & Whitney and SIAS. Each stage of the work is being scrutinised by a peer review panel including Transport Scotland's chief bridge engineer and consultant Flint & Neill.
"Replacement or augmentation of the main suspension cables will only be necessary if current efforts to tackle corrosion using dehumidification fail," stressed FETA convener Tony Martin. "The feasibility study that we have commissioned aims to determine the best way of carrying out this work, taking into account safety, engineering issues and the impact of restrictions on traffic and the economy. The information provided by this business survey will be used to assess the hidden costs of carrying out such a huge project. It should also prove valuable in shaping future strategies for bridge maintenance."
