In a Core and Shell project Office Tower that is over 50 stories, the rule is still measure all regularly occupied spaces in the building? That could mean over 50 floors of measurements?  Or is that in Core and Shell, we only measure the lux for regularly occupied Core spaces. But again, this could be a huge quantity. Is it allowed to do a representational number of floors, say 5 or 10? The same question applies if this was a complete BD+C Office tower that is 50 plus stories. To measure all regularly occupied spaces in an office tower could take weeks to do! What is allowable for maximum number of lux measurements? Thank you.
