North Stand Construction Discussion

A rubic cube looks a mess till it's finished. The Structual Engineers know what they are doing, let them do what they are good at and not tell them they are doing wrong. After all they spend 4years getting a degree, then have years on very difficult design projects. Then people come on here trying to say the have done it wrong.

I'm a Chartered Structural Engineer and I barely know what I'm doing.

I don't know a great deal about the project but I’d be cautious about making any firm judgments based purely on photos. The angle and perspective can be misleading, and in any case, all the key structural elements are monitored during construction to make sure they stay within the specified design tolerances.

It’s also worth keeping in mind that the structure might not be fully loaded yet, so any deflection seen could just be a result of temporary load conditions and doesn’t necessarily reflect the final behavior.

Lastly, the roof system relies on a tension ring, and the correct tension is only applied once everything is installed. Until that final adjustment is made, the structure may not appear exactly as intended.

This ^.

Could also be intentional, with the platform piece yet to be installed and sequenced in.

It is all part of discussion and speculation, which a small regular group have had here throughout and along the way. On the transfer, the 'clamp', the removal of the old pier, the quadpod ring supports, the caps, etc.

You would be surprised at how much guesswork and speculation turned out to be right, some good calls have been made. And then at times Sisk also surprised us. That's the fun of it.

It is however at this point imo a fair observation that the central bay looks to be off. Partially exaggerated perspective, sure, but combined with the ground photos, enough to notice. Really doesn't have to mean much more beyond that, and it doesn't have to turn into a moaners vs happy clappers divide either imho.

Genuine question now, for the wonky brigade. Do you find yourselves thinking that it is

a) the western beam that is too high
b) the eastern beam too low
c) each segment itself is fine, but the two halves of the roof back to separate quadpods are slightly misaligned, and the discrepancy incrementally tops in the middle bay.

To paraphrase the old Bernard Cribbins song:

The shape of it’s wrong,
It’s much too long,
And you can’t put a beam
where a beam don’t belong.

I don’t think anybody thinks that they did it wrong on purpose. Mistakes happen. It’s obviously not level, and it’s ok to have pointed that out
 
Remember when the beams (purlins) were first put in place, somebody on here suggested they’d put one of them in the wrong way round as the connecting weld points mid-purlin didn’t match up in line with all the others. What ever happened to that? Was it put in right after all or did they have to correct it in some way?

I love this thread.

Especially when you read posts like this from professionals.

Thanks for the insight.
 
If anyone can be bothered, can somebody point out on a picture exactly where the anomaly/kink/wonk n the roof is/starts, and I'll try and get some pictures of it inside the ground.

It is still as it was, and the same on the other side which wasn't in at the time.

It makes the circle shape to go on top of it so is deliberately out of line with the rest.

Only the east & west roofs rely on the tension ring now though? Presuming that it is the cable net you're referring to? Or does it have some sort of knock on effect on the north & south stand roofs?

Has anyone checked if the south stand roof is now not level ;)

We need the drone guys to go in close on the South Stand so we wonky theorists can check it out.

It would appear the left central beam is slightly higher than it should be.
 
Hotel occupancy rates must be good in the city centre. Continued hotel investment in Manchester is a good sign for the Medlock.

Holiday Inn Express on Oxford Road are planning to extend upwards with two floors above and an extra 24 rooms, a new planning application is online.

The central bay, where the red/orange lines are added. In theory it shoud appear level as per the red, but appears to dip as per the orange. The two beams should align, and the bay between them appear flat, but the west (left in the picture) one looks higher than the east (right in the picture).

Now worth stressing, the lines only apply as strictly if the drone is truly level. And truly central. Which I'm not convinced it is. But, amongst the various attempts, images and seeing the railing dip off the ground, there is enough there to appear that it is indeed lop-sided (for now).

You will probably get a better feel in person.

Im sure it will be perfect when finished. btw If nothing else I bet this thread gives the guys at Sisk a good laugh. btw In Italy people (mostly old geezers) who observe construction sites are so notorious they created a name just for them "umarelli"

I've encountered/engaged with a fair few of them over the years (the uk equivalent). Not always complete dafties either, should be said.

Haha, they’re just there in case any bodies get dug up from when the concrete was laid in the 60s.

If I remember rightly, I believe inside the Royal Courts of Justice there's one area that has an imperfection which was (allegedly) designed on purpose because the architect believed only God could be perfect.

It could therefore be something designed on purpose to provide a talking point.

Maybe the architects felt that the best way of coping with the stress of a football game from the south stand would be distraction. For those in that stand who look to the sky, they'll never quite get there before their eyes are focussed on the wonky roof - and whatever they were thinking about before would be out of their minds.

Option 2 - they fucked it.
