Here is a drawing I did for the pex heating system in the floor. I used an overlay of the 6x6 metal mesh condition and then used the mesh spacing to develop a layout with 4 zones of equal length and near equal coverage. I'll have to take final pics of everything before concrete to make sure if I ever drill the floor nothing is in the way.
Also attached is the revised basement beam layout for the lift that gets installed above. I had to upgrade from a W8-13 to a W8-15 to manage the point loads the lift creates
As a running total so far there has been 10 truckloads of 57's used in the slab on grade and as back fill around trench and foundation drains. The average load weighed about 6,600 lbs and was unloaded by hand and distributed in 5 gallon buckets. 6 tons of limestone dust on top of that with the shale the total amount of materials imported was about 108 tons.
