New Stadium Details And Discussions

[Adam456]

Checking the view from the old West Stand (tower crane 8) into the new bowl I see a deep channel, already with 8 or 10 piles or posts and a large dark box. Does anybody know what that is ? Is it the base of the pitch rolling machines mentioned above ? Or just basement in general ?

I think the 'box' you are asking about are the 'pile caps'. These are great big lumps of concrete that are used to join several of the piles together to better spread the load of what's above. You can see from the pile plan below that there are a bunch of pile caps planned for under the South Stand and none planned for the pitch area where just the piles will be enough. .

A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the foundation of a building, typically a multi-story building, structure or support base for heavy equipment. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence.[1]

no wonder I suffer so much with my farmer giles if that picture above has anything to do with it

Then you need pile caps to spread the load a bit!

Not sure if this already posted here...

BuroHappold (Berlin based)won the deal to the design for the rectractable pitch. Probably the SCX group is implementing their design (I am not sure what SCX role is)

Following excerpt from project report (probably 6 or 8 months old) gives a fascinating insight into how the sliding pitch is designed.

BuroHappold Engineering is providing multidisciplinary services from concept through to completion on this project. At the forefront of our mind is finding ways to ensure the old stadium remains in use while the new developments are taking place, as our client is keen to minimise the impact of the work on fans and also to preserve its vital revenue stream.

Tottenham Hotspur FC is also hoping to improve sightlines for spectators across the new stadium, and heighten their overall experience using the latest technology. In response to this, BuroHappold worked closely with our client and the wider project team to ascertain how best to meet these needs. The result was the creation of a groundbreaking retractable pitch.

Keen to drive forward innovation across the project, Tottenham Hotspur FC gave key members of the design team the opportunity to travel to various stadia around the world so they could study previous sliding pitch designs and ascertain how these could be modified and improved for use in this new stadium. These included the University of Phoenix stadium in the US, and the Stade PierrreMauroy in France.

Our engineers applied their findings from these research trips to inform our design for the sliding pitch at White Hart Lane, while also adapting to the challenges of this unique project.

Primary among these was working out how the pitch could slide beneath the permanent spectator seating of the South stand. Initial feasibility studies showed that it would be impossible for the stand to accommodate the pitch as a whole beneath it without compromising its stability and strength.

So instead, we proposed a pioneering solution by which the pitch will split into three sections before retracting below the stand. We’ve designed the front three rows of the South stand to be removable so that the pitch has room to descend beneath them. The edges of the pitch itself will then drop vertically downwards to create space around its perimeter, allowing the two outer sections to slide laterally outward and effectively dividing the pitch into three sections. These then slide longitudinally into slots beneath the stand, fitting around the required permanent support structures.

As well as creating a bespoke engineering solution for this unique pitch, BuroHappold liaised closely with the club and wider design team to phase work on the stadium to minimise impact on the fans as much as possible. Our design for the sliding pitch will aid this no end, as it will allow for the main 17,000 seat stand – the largest of its kind in the UK – to remain in operation throughout the duration of the work. This means that fans will be able to continue to attend matches, and the club won’t lose revenue.
​

It will be interesting to see at what point pitch is installed....

Sounds brilliant but I would be amazed if nothing significant goes wrong to start with. That many moving parts, almost completely new technology. There are going to be teething problems.

Thanks that makes a lot of sense with the cross section view. If you're going to put a column in you want a flat base but you can't drive a flat base into ground

Cheers

It is new technology but is it really that difficult to deploy? Maybe I'm wrong but more or less it is just sliding stuff on rails. I think the biggest issue is to keep the pitch in perfect condition or how they want to connect those 3 parts of grass into one so it will look (and work) as one unit.

Quite a bit gone from the park lane today. Is there a person to ask the webcam guys to show the demolition?

I worked for an engineering company that designed and made conveyor systems. If a small company like us (although doing work for Birdseye, Cadburys etc) can spend 12 weeks testing a new conveyor system then I am sure this lot will do plenty of testing to iron out any bugs.

It's funny but I have watched the ground come down and been pretty philosophical about it but now the Park Lane is coming down it has hit home, been standing in the Park Lane for fifty years and now it is no more. Gulp.

Exactly this.

Or this one!

 

[sherbornespurs]

..aaand this one. I was right in the middle, just above the crossbar - marvellous moment, the rest is history.

 

[Parklanerob]

Awesome. The old place will be missed but...... a stadium is nothing without the fans in it. The new gaff will rock

Don't fret mate...... vorsprung pitch technik!

Doubt it means too much but the official membership guide I've just had in the post is pretty unequivocal:

"Our new state of the art stadium is progressing well and will be ready for the 2018/19 season."

Hopefully an indicator that we're at the very least on track.
