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
