esshup, We pulled it up as we poured. Not being a large area it was no big deal. I wouldn't want to do it that way all the time fore sure. The rebar is 1/2" through a 5/8" hole "Hopefully" comes off easy.
And Yes sparkplug that is to pin it to the other slabs. Most of those will have 1" Insulation between heated and non heated slabs. the others will have an expansion joint.
