(OP)
What is the maximum depth concrete can be saw cut? We have a large 3ft deep slab that we may need to cut out openings to place deeper foundations for heavily loaded columns.






RE: What is the max depth concrete can be saw cut?
Saw cutting via circular blades is limited to blade diameters (/2) and there are concrete cutters that look like chainsaws that can go deeper.
There are also coring systems that could cut through at the corners and/or perimeter that could facilitate chipping the rest of the way.
There may be concrete coring/cutting subcontractors in your area that you could reach out to for guidance as well.

What I'd be concerned about is that a 3'-0" slab is likely to be thicker, especially locally, which would further increase the cost.

You may have to cut an area larger than what you need, jackhammer it out to the cut depth, then cut again (and maybe once more). Remember, you still have to get all that concrete out of there so you can't just expect them to cut a nice rectangle then pick it up. A 3'x3'x3' chunk of concrete weights 4,000 lbs. They'd have to do a ton of cuts or jackhammer anyway.
