Table 5   Classification of buildings according to their importance

Group 1

Buildings of great importance:
This group comprises four sub-groups, as follows:

a) Buildings which, if destroyed, will result in great loss of life, such as schools, mosques,
    stadiums, cinemas, theatres, large department stores, travel terminals and generally,
    confined spaces where more than 300 people are assembled.
b) Buildings whose serviceability after occurrence of earthquake is of special importance
    and whose destruction indirectly increases the number of victims and the amount of
    damage in the earthquake-stricken area, such as hospitals, dispensaries, fire-fighting
    stations, water supply centres, power stations and power transmission installations,
    communications, radio and television centres, police and rescue stations and generally,
    all buildings of which the use is effective in giving assistance and saving people's lives.
c) Buildings whose destruction will involve loss of national wealth, like museums, libraries
    and other institutions and centres where national national and other valuable documents
    are being kept.
d) Buildings and industrial plants and installations whose destruction will cause extensive
    air pollution or fire, like oil refineries, fuel storage tanks and gas supply centres.

Group 2

Buildings of Average Importance:
In this group are included buildings whose destruction will cause considerable damage and
loss of life, such as residential, administrative and commercial buildings, hotels, warehouses
and those of industrial buildings which are not included in Group 1.
Group 3 Buildings of Lesser Importance:
This group includes two sub-groups:

a) Buildings likely to cause little damage or loss of life if destroyed such as forage stores.
b) Temporary buildings designed for a period of operation of less than 2 years.
