We have initial foundation outline in place.

    We have the outline of the foundation in place.  They will be working on the forms this week, with an estimated day to pour concrete of  Monday May 19.

There's more to this foundation than just setting a perimeter form and pouring the concrete.  There are some conduits and pipes for water and sewer that need to be put in the correct locations, and there are a set of  beams that need to be dug beneath the load-bearing locations. Plus there are horizontal tension wires through the concrete (7 wire strands with tensile strength of 270K psi), and of course the rebar.

   This is a small version of the foundation plan, but provides some cross-section views of the beams that will undergird the slab.
