I am moving a large shed (32' long, 12' wide and 8'high) from one part of a site to another (it is sectional!). Currently the shed is on a concrete slab and sits up on concrete blocks.
At the new location I do not want a lay a slab, but I will be putting down a concrete foundation "ring" on which to lay the concrete blocks.
Very simply, how do I ensure that the concrete foundation is level front/rear and side/side over such a large area?
I can theoretically use a large spirit level and bash wooden stakes into a certain height, but at the end of the day, even a slight mis read over a total "ring" of 88' of foundations could lead to quite a height difference!
Are there any better ways or is it a spirit level, being very careful and possibly an iterative process?
Cheers
Peter
