I also noticed on the club CGI that them gaps are there too

On certain days the gaps will look less prominent than on other days simply due to the amount of temperature being held up in the metal structure

It's a really common thing in roofing projects - people don't realize quite how much these things move due to the elements of wind/solar load etc

It's all very much built into the design to ensure the integrity of the structure is not compromised by the local weather conditions.

Of course, being on the water the Wind Load requirements are pretty high, and the engineering to compensate for that is a marvel really

Cheers that's way above my intelligence level. I just figured we were gonna have 4 water features inside the stadium during rain because the club hates us :lol:

Even more prominent in the designers minds in this case was the change of foundation type. The middle section is the one that sits on the sand infill and is therefore more likely to move more while settling (which it has). If there were no gaps it would cause stresses on the parts that join the end stands that sit on the dock walls.

Excellent point - all engineered into the design to prevent over-stressing on the structure as time goes by.

It's basically the equivalent of Ikea telling us not to overtighten every screw when building a shelf - except this time the people building it actually listened

I wouldn't have thought that there was any 'settling' as that would be uncontrolled movement. Sand is a pretty solid base if it is fully contained. It will be more likely heat expansion that the gaps are needed

The 'gaps' are movement joints which are replicated through the entire structure. Each stand is effectively independant from the next in structural terms. The East and West stands sit wholly within the old infilled dock and are potentially susceptible to settlement over time due to the soft silts that were left insitu prior to infilling. The North and South stands straddle the dockside AND the infill so will potentially settle differently to the others.

When the Drone guys had their tour LOR confirmed to them that the East and West stands built mainly on sand had settled up to 60cm lower than the North stand which is mainly on solid ground. They had allowed for up to 1 metre in their calculations. There is a similar but smaller step down from the South stand to the E/W stands. These settlement gaps together with the lateral expansion gap (heat, wind etc.) will get covered (it has already started at NW corner) but that covering will obviously need to be flexible. It truly is complex to build on a reclaimed dock.
