What needs to be in the building during the air samples? I am confused about "moveable" furniture with "workstations and partitions" as examples when these are not really "moveable". The project is a medical clinic - workstations and receptions desks and room divider partitions have been installed and I think these must be in before the air samples are taken. But are owner exam tables, chairs, computer stations (the rolling ones) supposed to be in the building before air samples are taken?
