After a few days of digging trenches and laying pipe, I finished all the necessary under-slab drain plumbing (the white pipes), as well as the electrical service entrance (the gray pipe) and the water supply (black pipes). The top photo shows the Thermopex (insulated hydronic dual-PEX tubing) that was extended about 30 feet out from the barn, to eventually be connected to a central water storage heating system (this is part of the "master plan" to heat all buildings from one highly-efficient heat source). The bottom left photo is the main floor bathroom and utility room area, and in the bottom right photo you can see the drain line that will come from the master bathroom in the upper floor of the barn's silo. Today I covered all these lines with backfill. Keith is expected to return tomorrow so that we can reset the form boards and level out the site before the insulation is put down. Even though it is 90+ degrees outside, I want to celebrate by going out for a bike ride!
