We made a few of these and they were required to be a third party inspector (special inspection). The inspector watched us make them and accepted them. They were sent to the project site, and the on-site inspector saw that they were bent with the use of heat. He did not like that and rejected them. So I call the specials project manager to find out what was going on. He told me that as a rule of thumb that rebar is to be cold bent. I explained that this was dba not rebar and I would like a code reference for the why they were rejected. He says IBC. I ask for a more specific reference. His response was that it would take a while to try to find it. Additionally, it was our responsibility to prove that we could bend dba with heat. That he could not accept these without literature stating it was OK. I explained that this seemed oppisite from everything I had ever experienced. That if they were to reject these they would need to provide a code reference as to why. His response was they are rejected until i prove otherwise. So I told him to get me a copy of the report rejecting them.
