Photo from many many pages ago shows the connections quite well [emoji106]
 
What look like blank flanges have pre drilled holes in them. Probably look solid but they definitely wouldn’t fit them without bolts.

Surely the 4 legs will have to be at the correct angles before the cap can be fitted. Even if a leg or the legs are slightly out, the cap won't fit into place.

Probably but I can't see how the damned thing fits regardless given everything is angled. Are the two front pads physically connected in some way? They look like flat circular pads to me.

They will have thought about it.

Remember when we were all speculating how they would actually transfer the set of 7 cables from the top of the pier to the new angled trapesoid that was to be tensioned to the far back corners, and then go on to kerplunk the top of the pier out of the cage. They went and built a whole clamping piece, lifting beam above, braces etc, so they could lob it off in a onner.

They will have come up with ways to either pry those piers open, or alternatively tighten them once the piece is on. Seriously doubt they 'overlooked' that, given the thought we have seen that has gone into all the complexities here.

Why would they have gone to all the trouble of erecting a platform at the top of the pillars if they had not intended to fit the cap when they lifted it?

Something is not right.
 
It's typical. I haven't seen any of those paper instructions, blowing about that come with this type of pre fabricated stuff like Ikea. I often have to get my rounding tool out to make things fit in.

Maybe, probably. These things do happen. Time will tell.

The platform is and will still be there, and will be needed for attaching cables and doing/monitoring tests so it will be there for some time. It wasn't built just for yesterday nor is it critical to dismantle it.

I am completely open to it being any of the reasons speculated so far, or others we haven't yet thought of. We might also never really find out. I'm sure whatever the ultimate solution ends up being will be just as interesting as the likely issue itself.

If the hotel had been built where I’ve highlighted in yellow/blue/pink here, it wouldn’t matter how it looked because it wouldn’t be part of the stadium:

If, I think it will be very successful, I could see an additional hotel being built on site even more so if the collar sights has more visitor attractions that would merit an overnight stay

Yeah that would be 'not fitting' in a very different sense to it not fitting on because it was built the wrong size as some assumptions might run away with.

I think something that big, that high up, with such varying geometry, was always going to be a challenge to fit.

I had actually previously assumed they would slot it in at an angle pointing downwards.

The two cross connections, don't go as far down as it actually looks on the piers, they seem to stop about a third of the full cross length.

The issue is the same mind you, there will be a converging point to get past. It is just not as extreme as it looks.

Their biggest issue imo is, there doesn't seem to be any way of temporarily propping or restraining that piece while they try navigate it to meet 4 separate points.

Id be surprised if they didn't do a virtual fitting simulation of the cap, certainly in the automotive industry that would be the case, there is software that takes into account the human factor to simulate the weight of an object even harnesses and how they behavior when an assembly is pushed back can be simulated this can save money by reducing the flying length. Wondered, when it was on the ground, that it doesn't appear obvious how the bolts are fitted.

‘If’ it is a case of it not fitting due to the angles, the only way I can see to secure it is to remove the plates highlighted in yellow. 3 of the 4 legs could then be bolted up. The other half of the cross connections on that leg could also be secured.

How the hell you would support those plates when reattaching them is another matter?!

Someone made a lot of money for that crap design.
Send for Fred, a big hammer should fix it.

I agree with you about the angle. The crane is coming down vertical with that weight. It almost needs to come down at the same angle as mating part or it will jam up. Possibly cause damage to lugs.
There is nothing up there to tilt it as it’s slowly coming down.
You almost need 2 cranes working together but even that would be tricky even in a workshop.
Possibly modify one or the other to create more clearance. Then plenty of grease.

I'll come back to this, as it does somewhat tie in with the point I was making earlier.

If a guy overseeing it on site up there, feels something is unsafe to do or attempt, he damn sure is calling it off on the spot and trying again another day, no ifs or buts or questions asked, programme and cost be damned.

The fact they loosely lined it up, but never got even close to trying to fit it, while also never really seeming to have the piece restrained or under control to me suggests one of 4 things.

- it is either SO far out, that it is that obvious without getting it any closer. Which would be a big and costly fuck-up.
- it may be fine or nearly fine, but it just didn't feel safe to persevere or try.
- it was never planned to go in that day, and the whole thing was a bit of a practice run to see how it lifts and moves at that height in the air, so they can plan how to handle it for real.
- the dimensions and connections are fine, but getting them to fit in a sequence due to varying angles and convergences has not really been made clear or thought right the way through.

Of those, the first one seems the least likely tbh, and if that was the case, there would have been checking measurements and photos being taken as you point out.

5. One of the blokes up on the platform was Tolmie’s Hairdoo and he got a call about 115 just as they were about the fit the cap

No doubt of that, I'm not one of the people worried about this :)

After the caps are fitted I'm looking forward to see how the rest of the roof beams, the ends of the beams, the cross beam and the cables interact. I can't see any fixing for the cables on the beam that's up there although given how I missed the many holes in the front supports for the end cap that's maybe not surprising.

There's what looks like a rectangular hole in the beam that's up that I'm guessing will have the cross beam slid through and then the cables anchored to the cross beam. No idea how the ends of the beams work though, so I'm probably way out on that.
