Celebrating Success, Richard Hornby, Employers Delivery Team; Peter Curran, Ramboll; David Gough, FCBC at The Concrete Society Awards 2017
On both of these projects Ramboll’s experts drew upon the versatility of concrete in solving different but never the less complex technical challenges.
A prestigious body of judges from The Concrete Society, the Institution of Structural Engineers, the Institution of Civil Engineers and RIBA visited all nominated projects. They recognised the Queensferry Crossing as the outstanding nomination due to its technical achievements in the use of concrete, its demanding placement conditions and its innovative structural solutions and shear elegance in design. They also described this elegant bridge as 'a fine example of creative concrete technology for place-ability, strength, durability and surface finish quality'.
The Queensferry Crossing is the UK’s tallest bridge and the world’s longest three-tower, cable-stayed bridge, incorporating the longest composite deck span. Its 200m-high towers consumed some 165,000m3 of reinforced concrete, including a technically demanding underwater continuous concrete pour of 17,000m3.
Ramboll played a major role in delivering this £1.35bn project for the Scottish Government. View our short film in which Peter Curran, International Bridge Director, places the new crossing in context and shares some insights into the six year project.
On a much smaller scale, a £2.3 million seafront improvement scheme at Milford-on-Sea was one of the five projects Highly Commended at the Society's awards dinner. The structural capacity and functional stability of concrete suited the exposed coastal location and enabled the 3-in-1 scheme design: a sea-defence, promenade and modern private beach huts, all future-proofed to withstand a 1-in-200-year storm.
Integrating the huts into a sea defence structure and a new promenade has proved to be a sustainable solution. The mix of precast and in-situ concrete gave construction speed and cost effectiveness. The project utilised innovative techniques to significantly enhance the traditional seafront beach hut design. 119 storm-ravaged timber huts were replaced using standard culvert C-sections laid on their side to provide the basis for the replacement structures. The new huts have a concrete roof-top promenade with steps and ramps for pedestrians. The scheme features decorative concrete surfaces achieved with graphic printed concrete and intricate relief artwork surfaces. Read about Ramboll's involvement here.
All the nominated projects will be presented in December's Concrete magazine. More information from the Concrete Society here.
