Sir Robert McAlpine
Severfield was responsible for the engineering and supply of over 5,000 tonnes of steelwork for this magnificent 60,000 seater stadium.
We were appointed as the preferred steelwork contractor in a two stage procurement process. Following this, we worked closely with Buro Happold and HOK to develop the design that would achieve all client aspirations for a 'landmark stadium' and deliver 'value for money'.
The roof consists of two primary triangular girders 205m long and 15m deep, weighing 700 tonnes each. They are constructed entirely from tubes and were fully site welded due to their size. The primary girders support a series of secondary tertiary girders, which then span on to a doubly curved perimeter triangular truss. The geometry of the roof is extremely complicated and varied at different stages of construction. This had to be predicted by 3D modelling to ensure correct fit up onsite.
Severfield completed the steelwork to the roof on budget and ahead of schedule in July 2005
