GES not spelled out in plans

[jim dungar]

Worked on an apartment building recently where the foundation was a reinforced slab beneath the entire building. Foundation walls and piers were built up from there. The ground floor slab was several feet above the foundation slab.

Have also seen monolithic slab foundation that get thicker toward the outside walls. The outside portion is in contact with earth, while the inner portion is on a gravel base.

As foundations they can be CEEs, if they are on contact with the earth. A slab that is not a foundation cannot be a CEE.
In post #10, the OP says the walls are already going up so they must be on the building's foundation, yet the 'slab' has not yet been poured.
