One concrete floor.
Questions...
*looks like the vapor barrier, usually the first to be laid, is above? the WWF mesh, which itself needs support to half the depth of the slab for proper reinforcement.
*when will the flangeway blockouts come out? Hope they were oiled.
*slab finish looks rough, will make it harder to keep clean.
*no construction joints? Concrete cracks, wherever, whenever it wants.
Slab sealing is definitely needed.
And of course, treat that slab like it is radioactive, until mid-October!!
