Two years ago I started building a 50- X 60 foot all steel building with 17' side walls. The walls are insulated to R-30 and thee ceiling to R-38. The floor is 6" 4,000PSI four sack mix. The base floor was leveled, compacted, a 10 mil plastic laid and then 2" hi density foam board on top. Then #4 rebar was laid into rebar chairs and tied with standard rebar wire. Next pex tubing was fastened to the rebar in a predetermined pattern. Heated fluid will be pumped through the piping to provide floor hydronic heating.
We do also have a large bathroom with shower and laundry facilities and sink. Considering welding outlets, water bibs, air lines, RV outlets and a few other things,
Si far to date I have just north of $100K in the building. I have been the general contractor which has saved some expense.
