why are you adding a second beam? one not enough?
I actually didn't have to. I initially did the calculations as if it were a simply supported beam on two ends. In that scenario, it would need 2. In actuality, it's a beam that is essentially cantilevered on both ends. When calculating it that way, one beam would be enough. I figured for $150, it's good to be on the safe side and add the other beam. So the beam shouldn't be an issue. The city, if you're not going to have it ok'd by a PE, says you need a 12" footing beneath new posts. That would mean I'd need to pull the post out and put the footing in. Not impossible by any means, but if I can get a PE (KSU grad doing another KSU grad a favor) to write a letter saying it's ok, then I wouldn't have to cut concrete out and put the footing in.
If all this was covered in SDs thread let me know and I'll check it out.
