The mud slab was poured two days ago and is almost dry now. You can clearly see the indentations for the sewer lines. Along the right side and in the back right corner, you can also barely make out the indentations for the light wells.

On Monday, the plumber will come to lay the pipes. Then later next week, the steel (rebar) goes in, on top of the water protection layer. Brad hopes to pour the structural slab on next Friday.
