I had a monolithic slab pored last spring, been slowly finishing my shop as money and time comes. I paid to have the concrete work done as it wasn’t my wheel house and paying the contractor cash was very close to my costs after rentals and tools purchased.

Here is a pic of the form set up. The second picture is a 28 foot run and I see about 8 braces which is roughly 3.5 feet but if you consider the corners to be braced that would make 10 braces and the spacing less than 3 feet apart.

I don’t have any advice for you, but figured I would share what I recently had done.

Good luck with the rest of the build!
