Don't rely upon those tolerances!
Although FIRST surely put a lot of effort into preparing the field plans, those are wholly inappropriate tolerances for many of the dimensions given. They're not impossible, they're just impractical and unlikely to have been followed, especially for assemblies. (FIRST has never been very good at providing sensible tolerances for the dimensions in the game manual and drawings.)
Consider instead the advice of 6.1.1: "Fit and tolerance on large assemblies (e.g. the TOWER) are ensured only to within ¼ inch. Overall gross dimensions of the entire field may vary up to 4 inches. Successful teams will design ROBOTS that are insensitive to these variations."
