Floor, walls and bond beam

The previous post showed how we excavated, poured the footer and built the stem wall.  Following this, the vertical walls were assembled and the floor was installed. The floors are made to accommodate a radiant heating system. First a rigid foam is laid down, on the level compacted ground floor; then "Pex" TM pipe was installed.  

Concrete was then poured on top of the foam and pex, and screeded level, then the floor surface was floated. 

The walls were built up to header height, then a temporary scaffolding was built for roof assembly.  All exterior doorways had a masonry arch built over them, using wooden forms. The arches are fast and easy to assemble, they are also inexpensive.

After all the vertical walls were assembled, forms were built at the top of these walls; rebar was placed in this cavity as per the PE specification, and the form was poured with concrete to create a reinforced bond beam. 

With the bond beam made, roof construction was about to begin.  That's what I'll describe and show next..
