Measurement of Roof Levels

Carrie Martin: Chevron; April 10, 2012

Hello,

Am hoping you can help me.

My company is currently discussing how we should classify/measure our roof levels which commonly have building service areas on them so are accessible for maintenance personnel etc.

We currently measure the interior our office buildings to Method A of Office Buildings: Standard methods of measurement (ANSI/BOMA Z65.1 – 2010)

Should we be including the roof level within our Internal Gross Area calculations so that it becomes part of our rentable space ?

Thankyou in anticipation of your help.

Hi Carrie,

Unenclosed areas, whether on the roof or elsewhere in the building, do not normally count as IGA or Rentable Area. However, fully enclosed areas such as rooftop mechanical rooms are normally counted as Building Service Area. As such they are incorporated into Rentable Area calculations.

Hope this answers your question.
