Story

Probably the finest stadium on the Planet

The club’s chairman dreamed big, visiting stadiums around the world for inspiration and design ideas. His vision was to create a world class stadium that would also serve the local community, by being a catalyst for regeneration in an area that had been neglected for decades. The completed stadium has been described as a work of art. It is a project that we are extremely proud to have been a part of.

We were appointed to deliver the concrete frame for the main stadium bowl incorporating the bulk excavation, sheet piling, the construction of pile caps and the RC foundations, and basement box. The superstructure involved six number, nine-storey jump form cores, the construction of 112 terraced post tensioned slabs and the installation of 5,000 pre-cast elements to form the terracing to the North, West and East stands.

The construction of the stadium was extremely challenging but highly successful project for Morrisroe. We delivered high-quality, award-winning concrete finishes in a ‘live’ situation and to a timetable that could not afford to slip.  At the peak of our works we managed a workforce of over 500 people working 24 hours a day over three shifts. A significant milestone for us on this project was the 1.5 million man hours RIDDOR free.

“The logistics of the project were like nothing I had ever seen in my career – it was incredible”. Mark Reynolds MACE

AWARDS

The completion of Tottenham was a momentous achievement for the project team. Our work received formal recognition at the 2017 Post Tensioning Association Annual Award where we were awarded Best National Project for a concrete structure. We were also awarded, along with the project’s structural engineers Buro Happold, the IStructE Project of the Year in 2019, and were Project of the Year runners up at the Concrete Society annual awards.

THE FIRST HALF

It was a game of two halves. The construction programme was designed to accommodate Tottenham Hotspur’s home fixtures list which mean that two thirds of the new stadium footprint was available for construction during the 2015-16 football season around the old stadium whilst it was still in use. This first phase of work involved the completion of the basement and installation of PT slabs up to level 5, with core to level 9, with phased handovers to the steel erector to complete the upper levels to Level 9. This required exceptional coordination and precision planning with the client, the CM and the local authority to meet the various match deadlines. In order to safeguard the Club’s supporters we worked closely with the club, support teams and emergency services to ensure compliance with fan access routes for matches taking place during the construction works.

THE SECOND HALF

The second phase of works involved the demolition of the old stadium and the completion of the remainder of the new stadium to another extremely tight timeframe to enable Tottenham to return to their new stadium for the 2017-18 season. Despite numerous technical challenges arising from the structural engineer’s complex design, we were able to deliver our scope of works on time and to budget.

COMPLEX POST TENSIONING DESIGN

We worked with Walsh to develop the design for the PT slabs which needed to be integrated with the designs for the raker beams, steel columns and Y columns all of which would exert massive forces on the slab. We installed 112 Post Tensioned slabs for the stand, at peak installing 5-6 slabs a week, stressing and grouting 32T of strands per week. Circular ducts were selected for the ground floor slabs because of the curved footprint of the site but we were able to use more cost effective flat ducts in the upper tiers.

EXPOSED CONCRETE  

The quality of the exposed concrete can be seen throughout the stadium.  In-situ and precast raker beams interfaced seamlessly in both profile and colour match, and the structural floors polished to expose the aggregates in the final surface. As an addition our scope the club chairman requested that we undertake concrete polishing to the main concourse and toilet areas to expose the aggregate which was taken from the old ground at White Hart lane. This created a stunning finished effect with the stone embedded in the concrete polishing up to produce a floor that glittered with bronze and gold.
