The Rough-ins

Rough-in plumbing and electrical are placed in the ground below the concrete floor.
Our HVAC contractors laid 2" of rigid foam and plastic tubing for the radiant floor heat. We will be installing an indoor wood boiler. Our hope is to primarily heat the building with wood but we are required to have a back-up propane forced air furnace, which we will also use for air-conditioning.
We installed 6 x 6 wire mesh on top, and are now ready for the concrete floor.
