Here's my update from 23/6(Today).
Overview of Site.
This structure is huge, Pictures do not do this justice...
Towards the end of the day, I spotted that they had started to lay down the roof.
There is a big concrete block which, I assume will go under the lift hill and will be the building that controls the lift/launch system. Also I have a feeling the 2nd drop (traditional curved GCI drop) will be quite steep as the banking on the wooden structure on the far right of the theming structure is banked at a steep angle.
