Level
7.4.4.1
The LEVEL Field is an Optional Field. If it is populated it should contain a textual description such as “Basement”, “Ground”, “First”, “Second”, “Third” etc. If the BLPU occupies more than one level this must be recorded with the lower level first in sequence, for example, “First and Second”.
7.4.4.2
In some instances more detail may be added after the position to provide more definition to assist in the location of the BLPU, for example “First Floor Rear”.
