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,
Draw
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.
