Pell Frischmann Wins IStructE Structural Heritage Award

Pell Frischmann Wins IStructE Structural Heritage Award

By Keir Pratt

We are delighted to announce that Pell Frischmann won a major award at the 2014 Institution of Structural Engineers' Awards, the industry's most prestigious awards ceremony which celebrates international excellence in structural engineering. Established in 1968, they recognise and reward the work of the world's most talented structural designers, their indispensable contribution to the built environment and showcase projects that lead the industry's development. Our project to strengthen and restore the Grade A listed Forth Rail Bridge won the award for Structural Heritage, a category which celebrates the restoration and conservation of a project of historical and cultural importance. The 124 year old Forth Rail Bridge, being the first large span bridge to be built using steel and the second longest cantilever ever built, certainly fits the billing and our project to properly recoat it for the first time since its construction was praised for its ingenuity, longevity and comprehensive approach to the task.

Our project saw the culmination of nearly 20 years of work and Network Rail and Pell Frischmann were responsible for all the civil and structural engineering elements of the bridge's restoration, and we supervised Balfour Beatty in the construction works and the bridge's repainting. Starting in 1995, we carried out an integrity study and condition survey, hazard report and structural analysis of the primary bridge members. In total there were 4,500,000 working hours where 240,000 litres of paint, sprayed onto the entire 255,000m2 surface and applied by hand to 6,500,000 rivets and sharp edges. As the newly painted topcoat will last at least 20 years, the 3 million passengers who use it daily will have access to uninterrupted views for decades to come. Congratulations to all involved in this prestigious project and for the very well deserved win.
