Re: New at Piping Design Central: Machinery Grouting

But don't you think that "underside of baseplate" is a better/more useful description? That definition clearly places the concept within the realm of mechanical equipment location (which is much closer to the piping discipline) and not the civil engineers. You don't want to start mixing metaphors with concrete designers on a big project unless the intent is to cause useless inter-departmental meetings wherein the piping guys most always win. And then have to politically smooth everything over for continued overall project group harmony.

"Underside of baseplate" (not T.O.G.) should always be at elevation 100'-0", except for special cases. If there are enough questions as to why and I feel like writing, I'll explain later. Or maybe someone else will chime in.
