Question 6 was for me not clear and too long. Therefore I put it in pieces. Is it right as it is specified here?

 

Question 6 :

Does the reference show the subfloor structure comprises the following:

- An integral subfloor bowl hull made of a U-shaped one-piece, made of a composite material, or a single pieced metal and

- The subfloor structure defines at least: the bottom central portion, two lateral transition regions and two upward web portions, having the bottom central portion and the integrated upward web portions constructed in a one shot curing step.

-The integral subfloor bowl hull spans over at least 2/3 of an overall longitudinal dimension of the subfloor structure, below the floor surface?
