North Stand Construction Discussion

Surely we will have blue up lighters ??

Nothing yet to suggest it, not seen anything in the PA that includes it. A few mentions of strategy for internal lighing and wider site lighting, but nothing aesthetic or facade related.

There are however two conditions to the approval that look for details of any lighting schemes and their use, to be subsequently discharged, so something may still come in. Or they may think what had been covered in the approval is enough and go with that.

I don't think that is the case, and here is why. I have btw tried to guess it from when these rods first appeared or were pointed out a few weeks ago, and to use the old phrase 'I got nothing'. Others are more than welcome to chip in with alternative thoughts.

Any inherent slack would have surely been factored and built into the catenaries decades ago, as this is the original cable net. It is also tensioned back at each node, which was all lazer monitored through the months of transfer off the original piers.

It then went on to stand freely fully self supported for months, while the new roof was built around it. Doesn't (to me) make sense that it should need retentioned at this point after all that.

It is possible that following all the works, there is a 'spring' effect on the ring. But as above, it stood free standing (by that I mean without any interference) for ages, and they would have had to rectify that months ago, not wait for a new roof to be built to tighten it. Also, it would presumably need pushed the opposite way, rather than tensioned, as the spring would be in theory be upwards rather than downwards, having shed the weight of the old roof below it. And if that were the case, you would think it would need more the two slender sets of rods in two locations.

To me it looks more like these are for the new roof above, rather than the cable ring itself, either on a temporary or permanent basis.

To minimise wind uplift on the new junctions till it is all fully fitted and properly tensioned? This is logical, but again, just doesn't look enough for that.

Or alternatively, these rods could have been what was used to rectify 'the wonkyness' of the beams and tighten them down rather than faffing with the catenaries above.

The truth is, I am puzzled why they are there, and none of the thoughts I have had on it are convincing enough for me, but I am sharing them anyway. I don't see them being permanent, but purely because I can't seem to see their purpose. Maybe someone else will hit on it at some point however.

The only person who can enlighten us on this is a bona fide structural engineer, otherwise it is purely guess work. Me being Mechanical, structural is just guess work with some knowledge of the structure of steel wire ropes.

And even then would be primarily guessing, unless involved, with something as specific as that.

It's almost as if they have a schedule of works and are sticking to it, very peculiar ;)

Works the other way of course.

If a course of action is scheduled for a certain date and it has not even been designed, the contractor still turns up to do that task and get work sheets signed before being assigned different work or risk not working to contract.

At least that's how it used to work on long running contracts in my day.
