3.0 Built-Up Area

The DM Submission definition of FAR is different from the internationally accepted definition. The DM Submission definition is a measurement of area.

Built-Up Area (BUA) is the total constructed floor area of a building.

The Floor Area Ratio (FAR) includes the following: A (Usable Areas) B (Circulation Areas)  

When providing BUA calculations to DM the BUA should be described as the total of the following areas A (Usable Areas) B (Circulation Areas) C (Balcony Areas) D (Service Areas) E (Roof Slab Area)1   

The FAR excludes of the following: C (Balcony Areas) D (Service Areas) MEP Shafts 

 

 

BUA is exclusive of: MEP Shafts 

Exceptions to the above rule: Lift shaft area is to be counted as B (Circulation Area) for the Ground Floor only. On all other floors, lift shafts shall be considered as MEP Shafts. 

FAR = A (Usable Areas) + B (Circulation Areas)

BUA = A (Usable Areas) + B (Circulation Areas) + C (Balcony Areas) + D (Service Areas) + (E) Roof Slab Areas 1
