Scope of Works
- Standing seam roof
- Bull noses
The London 2012 Velodrome’s highly distinctive form – an award-winning, double-curving, structure designed to reflect the shape of the cycling track – used a range of extremely efficiency design solutions that helped make it one of the most sustainable buildings of its kind.
Lindner Prater was appointed to carry out complex roofing works incorporating 13,000 sqm of aluminium metal standing seam roof, eight 100 m long roof lights, 420 lm of bullnose to the perimeter and 22 movement joints.
A cable net roof structure, the first of its kind, was specified to ensure maximum spectator visibility inside. This required a theoretical 500 mm movement when under full load. Movement between the cable bays was also significant so we developed a ‘movement strategy’ that included the use of movement joints within the roof at 7 m centres.
The architect’s vision was to create a bullnose perimeter that flowed and wrapped over the roof shape, and we designed a support system that enabled the ‘build’ tolerances to be overcome in all directions, ensuring the smooth, curved appearance was maximised.
We specified recycled materials where possible, such as the aluminium coil used for the roof sheets, to ensure the roof met the sustainability targets. The roof lighting reduced the need for artificial lighting, natural ventilation minimised the need for air conditioning and water saving fittings were installed to collect rainwater for reuse.
