Week 15 - Concrete Square Detail

The concrete squares sit in a grid that alternate over the level as seen in previous blogs.  The image below shows the concrete square sitting in place

How the concrete square sites in the hole with the particular edges that hold it in place.

The diagram below shows the concrete square removed from the hole.

The diagram below shows a smaller section placed into the hole to allow for access through the corridors. As the corridors are 6m wide and the cut outs are 6m wide too, a smaller section must be put in place to allow people to access all parts of the underground community.

The section below shows how the concrete squares sit in place within the cut outs. Also shows the shape of the concrete squares  relative to the holes.
