How big are the bars? What type of demand is on the bars? What is the foundation system the column is sitting on?

You will get lots of technical answers here. But what does your Contract say? This should be your guide.

Generally not a big deal for smaller, non-frozen, non-galvanized bars bent once. Unless this is the base of a special seismic moment frame, I wouldn't get too excited.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Small bars get site bent around here all the time during construction, we generally pretend it doesn't happen but we know it does. As Koot indicated, provided a few exceptions this normally is not an issue.

I'll third that, as these aren't 90 degree bends I wouldn't be worried about carefully bending them back. A little heat (not red hot) will make them bend easier and help further with any concerns. They'll never be perfectly straight but some rectangular ties and a little bit of work will force them back into the correct orientation.

If you're 100% against bending them back then you're likely not going to get anything other than demolition and replacement to make much sense.

About the only other solution that comes to my mind is cutting them off at the base and welding on new bars, but this is only if the bars were weldable. I would not do this as even my 3rd option, let alone my first. Bend the bars back is much safer than any sort of repair or replacement of the bars.
