   BB say 10' by 10'. Do you agree with that pattern?

   Not at all, BB is absolutely correct as am I .
   Go back and re-read your question. You asked how often. Why would you want to cut your slab multiple times? multiple places I can understand , but multiple times?

   Thanks. I trust BB but I just wanted to know if there were regional differences. I'll get a lesson on local practices. So far, I've been very underwhelmed with the concrete guys but this slab will be done by a much more sophisticated crew, I hope.I understood your first answer. I could have argued the point and said that it's often easier to make the four cuts at 1/2" deep on each pass, for a 2" deep total cut and therefore we'd be cutting the slab four times. I appreciate the help and/or the humor.

   it really depend on the shape of the slab, it will crack on any sharp corner, so if it was L shape it would crack there. If it narrow and long
   then you could cut the narrow once and then the width the same size. if you have a long hallway, cut underneight the studs to hide the cut. any block out will crack so have the block out turned so the cut hits the corner of the block outs. any thing that comes through the floor needs a blockout. if you make the block outs round like a five gallon bucket, that will keep it from cracking.also cut it deep, 4 inch slab 1 inch to 1 1/2. cut the slab the same day. like within minutes of the finishers walking off the slab. Slab start cracking within 12 hours. as it starts to cool off it starts pulling.all slab crack, no, thats the famous words of a crew that too stupid to do their job right.

   What are their plans for damp curing the slab?

   How thick is your slab?

   My concrete guy also said ... every inside corner running both ways in addition to e.g. the 10 x 10 (or whatever is nice and even under that grid. Never had significant cracks at all. Is your slab poured w/in walls? If so, consider fiberboard around the perimeter. Not sure what others think, and I'm no concrete expert, but seems like that allows a little give for the slab as a whole. I've seen it done a lot, but I've seen some that don't.
