Survey Practice in Facility Work

Survey Practice in Facility Work

Survey Practice in Facility Work

(OP)
What's the consensus, it is common practice in facility (vertical) work to state elevations with negative values on design plans? I think not, but I'd like to hear what others have seen/done.

RE: Survey Practice in Facility Work

I've seen it numerous times - usually where the designer has noted a top of floor elevation on the plan sheet for each level.  Then there is a global note that states that dimensions shown on the plan in the form of (-2 1/2") are top of steel elevations below or above the finished floor elevation given.

This is a handy way to communicate various top of steel elevations when they vary on a floor level.  Usually this occurs due to joist seats, brick supports, etc.

 

RE: Survey Practice in Facility Work

I do it on almost every job.  I usually refence the absolute floor elevation and then reference the various elements relative to the floor using plus or minus e.g. top of footing (-2'-0") or top of steel (-6").
