Can't really see how this can be done, most offices have terrible GPS reception. Thus using GPS is out of the questions, als it will not be precise enough.

You could try using bluetooth although it very limited in iOS and you would have to place bluetooth dongles every wehe.

My guess it can't be done with the precision that you need.
