Figure 3.
The image displays a structural layout divided into nine distinct zones arranged in a circular pattern. Zone 9 occupies the central region and is surrounded by eight equally spaced outer zones labelled Zone 1 through Zone 8. Each of these outer zones extends radially from the perimeter of the central zone to the outermost boundary of the circular structure. The boundaries separating the zones are delineated with thick lines extending from the center outward. Structural elements and reference markers are arrayed around the circumference, with radial lines connecting them to the center, suggesting modular or radial assembly components.Expansion joints and zones
