Overview:

The steel construction for the North, East and West stand bowl structure for Tottenham Hotspur took place during the 2016/17 football season, whilst the old White Hart Lane stadium was still in operation. Severfield facilitated the early construction of the feature Y-columns (200 tonnes each) within the East stand in late 2016, and the main build of the North, East and West stands then followed from Jan 2017.

South stand works commenced during the summer of 2017, following the demolition of White Hart Lane stadium. The South stand contains two steel ‘trees’, each weighing 275 tonnes, provided by Severfield. The trees are a unique architectural feature, supporting the back of the new single-tier stand.

The complex roof structure, engineered by Schlaich Bergermann Partner, is formed from structural tension cables, fixed back to the compression ring, which creates the outside profile of the stadium. The compression ring comprises of 54 box girders, each measuring over 20 metres long and weighing approximately 25-30 tonnes each. This was fabricated and trial-assembled at our Lostock facility, helping us achieve an accuracy in length of less than 1mm. Once constructed on site, this produced a ring with an overall length deviation of 0.001% over a 693 metre total length.

The roof lift itself required an incredibly complex synchronized strand jacking operation, involving 216 strand jacks, making it one of the biggest synchronized strand jacking operations ever undertaken in the UK for a single lift.

Severfield also supplied the steel trays for the pioneering world-first dividing retractable pitch, enabling the new stadium to be used as a highly flexible sports and entertainment venue.

The completed stadium will provide Tottenham Hotspur with state-of-the-art facilities and increase the spectator capacity to over 62,000.
