I'm having a concrete slab poured that we will be placing a shed on. It will be about 12' x 12'. When placing the forms, the diagonal measurements were off by about 2 1/2 inches. The contractor said this was okay and normal. In my logic, it won't be square unless the diagonals measure accurately also (he didn't have a cornering tool). Before I go any further with this, could someone advise me? Thanks!

Measure from the inside of the form in the corner 6' one side, 8' on the other then across the diagonal ( hypotenuse )will be 10'.

That is the typical way we sqaure buildings, it's the pythagorean theorem.

The theorem that the sum of the squares of the lengths of the sides of a right triangle is equal to the square of the length of the hypotenuse.

I wouldn't start a building not to square.

Thank you very much for your help! We're building the framework ourselves, and will use this for squaring.
