The recommendation from experienced (OK Old) mentors is to build to 1/4" under in every dimension. Tolerances in bending are finite and they could be too big. Whatever way the Inspection team decides to measure the Frame Perimeter, it better be less than 112". The guideline is using a 112" string wrapped around the robot frame. Boltheads, welds minor protrusions are different than a misplaced bend, angle stock in the corner or a transmission that stick outs from the frame. We call this practice "playing with fire".
