Some of the world's best architects have helped engineers scoop top awards for design.
Birmingham's Selfridges by Future Systems and Arup was 'an architecturally challenging and exciting building', said judges for the Structural Steel Design Awards. 'But it had a commonsense approach to its structural framing strategy'.
Another Arup building, More London Plot 1, created by Foster and Partners, 'pushed the design process to the limit'.
Meanwhile, 'a culmination of collaborative expertise and teamwork' was the judges' verdict on the third award winner, Wilkinson Eyre's Swansea Sail Bridge engineered by Flint & Neill Partnership.
An industrial building award went to Portsmouth's VT Shipbuilding Facility by AMEC Design and Management with Watson Steel Structures for its impressive scale, use of traditional steel structural forms, and efficient design.
'Engineering excellence, innovation, attention to detail, economy and speed of construction are characteristics of these exemplary structures, ' the judges added.
