I previously posted about top of column cracks due to plastic settlement and shrinkage, and have a follow up post to get some opinions. The contractor used insulation foam to close off the forms between the beams and columns. The foam (surprise!) over-expanded into the column cross section, and at this point I have no doubt contributed to the concrete already cracked and weakened by plastic settlement. Based on the photos below, it also looks like the columns and beams were poured at the same time. I'm a bit exasperated with the amount of screw-ups here, and debating if some of these columns should be scrapped and re-poured completely, or if the damage can be routed and patched w/ n.s. repair mortar and FRP. A couple of these columns are also meant to act as portal legs - fyi.
