2. • Means a building or a group of buildings constructed or

more than one dwelling units and having common
service facilities.
• Campus planning / Layout of Buildings, a pedestrian
approach to the buildings from road / street / internal

GROUP HOUSING

3. Floor area ratio (F.A.R)
• Floor area ratio (FAR) is the ratio of a building's total floor area (gross
floor area) to the size of the piece of land upon which It is built.
• It is often used as one of the regulations in city planning along with the
building-to-land ratio.
• The terms can also refer to limits imposed on such a ratio through zoning.
Written as a formula, FAR = gross floor area/area of the plot.
total covered area X 100
FAR = ——————————
plot area
Total built up area on ground level X 100
 Ground coverage =. ------------------------------------------------------
Total plot area
FOR INSTALLING SOLID WASTE MANAGEMENT PLANT 3%
EXTRA.

Staircase rules

30. • Spiral not less than 1500mm in diameter.
• External exit door of staircase enclosure at ground level
shall open directly to open spaces.
• No living space, store shall open directly into staircase.
• Each floor of the building should have two staircase exits for
faster evacuation during a fire. This is crucial for buildings
where residential accommodation exceeds 150 sq meters of
the floor area and holds a capacity of 20 occupants. Also,
the width of the staircases should be at least two meters
wide since narrow staircase heightens the risk of a
stampede during evacuation.

31. • Apart from the regular lifts used by the
residents, high-rise buildings should comprise
separate lifts exclusively for firemen in case of
an emergency. The speed of the fire lifts should
be higher than the regular elevators. The speed
should be such that the firemen could travel from
the ground floor to the top level within a minute.
• it will need a pit depth of around 1100 mm and a
headroom of 3400 mm. In case you have
additional pit space, you can easily get an extra
ramp installed on the lowest floor of your high-
rise building.
• Most of the residential lifts are 3’ wide by 4’
deep or 0.91 x 1.22 m in size.
LIFT NORMS

32. Safety rules regarding refuge area -

Safety rules regarding

33. • Mechanical ventilation must be provided
(exhaust fan).
• Ensure that appliances can all open without
interfering with one another, and that standing
space is provided.

34. • Massive static water storage in the form of

basements used for car parking or storage
occupancy exceeding 200 meters.
• Every building with a height of more than
25 meters should have diesel generators
which can be used for controlling fire in the
case of power failure.
Fire-fighting measures

35. • In large-sized buildings where accidents due to fire may
not be easily noticed, automatic fire detection and alarm
facilities are must be provided.
• In such buildings it should be protected by fire
extinguishers, wet risers, automatic sprinkler
