Definition of High Rise Building.
If we see this in Indian Scenario, there is lot of confusion and ambiguity in this definition itself. As per National Building code – 2005, all buildings of 15 m or above height comes in the category of high rise. This distinction is purely on the basis of fire safety requirements in these two broad categories of buildings. Whereas, various mega cities master plan in India define these differently. The Bangalore’s revised Master Plan – 2015 defines a high rise building or a multi storey building as a building of a height of 24 meter or more above the average surrounding ground level. Similarly, in Mumbai also the high rise buildings are defined of 24 meter or above and in Ahmadabad it is defined as 18 m and above. However, in Delhi MP the norm of 15 m and above is followed.
Now if we look at Global definition, the definition provided by Council of Tall Building and Urban Habitat (CTBUH) are followed in almost all the countries across all the continents. According to CTBUH the broad definition of a tall building is a building of perhaps 14 or more stories or over 50 meter (165 feet) in height. Also CTBUH defines a super tall building which is over 300 meter (984 feet) in height. Although great heights are now being achieved with built with built tall buildings – in excess of 800 meters (2600 feet) at the midpoint of 2011, there are only approximately 54 buildings in excess of 300 meters completed and occupied globally.
