The contractor should of used heat to bend these bars, he didnt, i want to know what problems can be attributed to cold bending a bar when it should of been heated.
As far as i can see, if a number 7 rebar is to be bent in the field, it shall be bent using heat. What happens if a # 7 rebar is bent without heat? (note it was only bent once and still needs to be bent back in place)
