I'm looking for 2 things.
1. What is the best way to heat a 90,000 sq ft shop 60,000 is already built and in place 30,000 is going to be built?
2. What is a rough ball park cost?
Thanks,

Pad thickness
3-4" is 3 feet
3/4" is 1 foot
Under the pad is rock (see picture)
Yah i know the ground pressure exerted by the tracks (48.9 psi) but i dont want to have to put that much cribbing under my jacks b/c we need to be able to work in there.
In the first picture the shovel is on the...
I'm jacking up a large electric mining shovel (1.5m lbs) and am wondering what a safe bearing capacity would be?
The pad is built out of 3-4" rock with a layer of compacted 3/4" crush on top.
Sorry here are the equations.
F(shear) = 0.5Sy * A(shear)
F(bearing) = 1.2Su * A(bearing)
F(tensile) = 0.6Sy * A(tensile)
What do you mean crushing stress?
