The primary objective of this report, drawn up by Central Public
Works Department (C.P.W.D.), Ministry of Urban Affairs and Employment, India,
is to frame guidelines for non-ambulant (chair bound), semi-ambulant (lower
limb impairments), visual, and hearing disabled persons.
construction and maintenance standard should be followed in all categories of
buildings and facilities used by the public for making design accessible to,
and functional for, physically disabled persons. Although the recommendations
are concerned exclusively with the requirements of disabled people, but the
facilities will invariably make buildings more convenient for elderly persons
and persons suffering from any kind of physical aliments. A safer, easier environment
for the physically disabled benefits everyone. The main purpose is to integrate
disabled and elderly persons fully into the society. The presumption that all
elderly are handicapped, is an over simplification of the needs of both groups
and is a disservice to both.
Builders, designers and architects are ultimately the users of this standard
to ensure that the specific environment created by them is suitable for all
categories of people. The standard also indicates that barrier-free design can
be achieved without economic burden to the client, builder, designer and the
architect. It will help to provide a framework for developing policies to ensure
a barrier-free environment and eliminate the lack of awareness in both the public
and private sectors to the problem of accessibility.
Excerpts from Guidelines and Space Standards for barrier-free
for Disabled and Elderly Persons
Central Public Works Department, Ministry of Urban Affairs
and Employment , India, 1998
The C.P.W.D. guidelines are recommendations for designers
and architects and cover the following areas:
- Type of disabilities
- Mobility devices
- Constructions and maintenance standards
- Classification of buildings
- Minimum access provisions required in various types of
- Design elements within the building premises (public
- Guiding/warning floor material
- Other facilities
- Design elements outside the building
- Residential buildings
- Railway stations
- Model building bye-laws
Below are excerpts from the guidelines. If you want to view the complete guidelines,
please email us at firstname.lastname@example.org
A barrier-free environment is one which enables people with disabilities to
move about safely and freely and to use the facilities within the built environment.
The goal of barrier-free design is to provide an environment that supports the
independent functioning of individuals so that they can get to, and participate
without assistance in everyday activities such as procurement of goods and services,
community living, employment, and leisure. The fundamental principles should
be followed in developing standards/norms for various facilities to meet disabled
people’s standards for safety, convenience and usability. Barrier free
design standards should satisfy anyone who is hampered in his mobility or functioning
(as compared with a non-disabled person) as a result of obstacles put in his
way by the design of a building, the choice of hardware and equipment, and the
arrangement of outside space.
The primary objective of this report is to frame guidelines for non-ambulant
(chair-bound), semi ambulant (lower limb impairments), visual, and hearing disabled
persons. This construction and maintenance standard should be followed in all
categories of buildings and facilities used by the public for making design
accessible to and functional for physically disabled persons. Although the recommendations
are concerned exclusively with the requirements of disabled people but the facilities
will invariably make buildings more convenient for elderly persons and persons
suffering from any kind of physical ailments. A safer, easier environment for
the physically disabled benefits everyone. The main purpose is to integrate
disabled and elderly persons fully into society. The presumption that all elderly
are handicapped are elderly, is an over simplification of the needs of both
groups and is a disservice to both.
Building types to which the recommendations may be applied are residential
buildings other than domestic buildings, healthcare institutions, educational
establishments, community and religious centres agriculture and transport facilities.
The guidelines have also indicated the minimum access provisions required in
various types of buildings.
This standard shall be a valuable document to exchange comments between disabled
consumers architects and others interested in an environment which does not
exclude disabled people. This may also generate research activities to provide
required knowledge base.
Type of disabilities
Various disabilities which have been considered while preparing the guidelines
for barrier-free built environment are broadly classified under four categories
1. Non-ambulatory: Impairments that, regardless of cause or
manifestation, for all practical purposes, confine individuals to wheelchairs.
2. Semi-ambulatory: Impairments that cause individuals to
walk with difficulty or insecurity. Individuals using braces or crutches, amputees,
arthritics, spastics and those with pulmonary and cardiac ills may be semi-ambulatory.
3. Sight: Total blindness or impairments affecting sight to
the extent that the individual functioning in public areas is insecure or exposed
4. Hearing: Deafness or hearing handicaps that might make
an individual insecure in public areas because he is unable to communicate or
hear warning signals.
- Adequate space for persons using mobility devices
- Adequate space should be allocated for persons using mobility
devices, e.g. wheelchairs, crutches and walkers, as well as those walking
with the assistance of other persons.
- The range of reach (forward and side; with or without
obstruction) of a person in a wheelchair should be taken into consideration.
- Attention should be given to dimensions of wheelchairs
used locally. Standard size of wheel chair has been taken as 1050mm x 750mm.
- Locking and opening controls for window and doors should
not be more than 1400mm from the finished floor usable by one hand.
- Switches for electric light and power as well as door
handles and other fixtures and fittings should be between 900 mm-1200 mm from
- Power point for general purpose should be fixed between
400-500 mm from the finished floor.
- A wheelchair user’s movement pivots around his or
her shoulders. Therefore, the range of reach is limited, approximately 630
mm for an adult male.
- While sitting in a wheelchair, the height of the eyes
from the floor is about 1190 mm for an adult male.
- A wheelchair has a footplate and leg rest attached
in front of the seat. (The footplate extends about 350 mm in front of the
knee). The footplate may prevent a wheelchair user from getting close enough
to an object.
- Manually operated equipment must be designed to be
easily accessible from a wheelchair.
- Make sure that the coin slots of vending machines,
etc, are located no higher than 1200 mm.
- Allow a space at least 350 mm deep and 700 mm high
under a counter, stand, etc.
Construction and maintenance standards
A) Non-ambulatory disabilities
- Persons restricted on wheelchairs should use the facilities
within the built environment alone without a helper’s assistance.
- A wheelchair may be operated by the user alone or with
a helper’s assistance. However, wheelchair design must assume that the
user should be able to operate the wheelchair without help.
- The width and length of the wheelchair, its control and
the diameter of the casters decide the following:
- Width of entrances and exits (clear 900 mm)
- Width of the passage/corridor (min. 900mm)
- Slope of the climbing (min. ramp slope 1:12)
- Passing over different levels and grooves (Grating with
narrow slots in the direction of movement and level difference to limit to
2 cm or less)
- Transferring from wheel chair (adequate space is required
to transfer from wheelchair to toilet seat and bed.
B) Semi-ambulatory disabilities
Persons in this category are those who use walking aids such as crutches or
canes, who are amputees, who have chest ailments or heart disease. The persons
in this category include those who can not walk without a cane and those who
have some trouble in their upper or lower limbs although they can walk unassisted.
- Width of passage for crutch users (min. 900 mm).
- Finishes of floor surface with non slip floor material.
- Installation of handrail to support the body weight at
critical places, for example staircase, toilet, ramp, passage with a change
of level (800-850 mm).
- Extension of handrail on the flat landing at the top and
bottom of the stairs (300 mm).
- To prevent a cane or crutch tip from slipping off the
side of the stairs or ramp, install a 20 mm high lip on the exposed edge.
Persons in this category are blind or with impaired vision. Visually impaired
persons make use of other senses such as hearing or touch to compensate for
the lack of vision. It is necessary to give instructions accessible through
the sense of touch (hands, fingers or legs). While walking with a cane the person
may bump his or her head or shoulder against protruding objects. Persons with
may be able to discriminate between dark and bright shades and defferences in
- Use of guiding blocks for persons with impaired vision
to guide them within the buildings and facilities and outside the building.
(Refer details of guiding/warning blocks).
- Installation of information board in Braille.
- Installation of audible signages (announcements).
- Removal of any protruding objects and sufficient walking
space for safe walking.
- For persons with limited vision: use of contrasting colour
- Provision of information board in an easily understandable
- Provision of illuminated signages, layout diagrams to
help people easily reach the desired place.
Elderly persons may suffer impaired mobility. Sight disabilities (partially
or fully), hearing disabilities or any other physical difficulties, for which
the design guidelines for them within and outside the buildings and facilities
shall be similar to those for other physically disabled persons.
Minimum access provisions in various types of buildings
- Single detached, single dwelling units: A minimum of
2% total number of units to be constructed with barrier-free futures
- Staff housing, multiple dwelling and high rise residential
units and tenements: A minimum of 1 unit for every 25, plus 1 additional unit
for every 100 units thereafter. Entrances and exits to be accessible.

assembly halls, cinemas, theaters and other places of public assembly: Accessible
entrances, exits, aisles and main community or public gathering areas. Accessible
toilet facilities should be nearby. Seating for persons with disability to
be provided for persons in wheelchairs throughout the main seating area. A
minimum of 4 wheelchair spaces for seating capacity from over 100 to 400 seats
Walks and paths
- Walks should be smooth, hard level surface suitable for
walking and wheeling. Irregular surface as cobble stones, coarsely exposed
aggregate concrete, bricks, etc, often cause bumpy rides.
- The minimum walkway width would be 1200 mm and for moderate
two way traffic it should be 1650 mm-1800 mm.
- Longitudinal walk gradient should be 3 to 5% (30 mm-50
mm in 1 metre)
- When walks exceed 60 metre in length it is desirable to
provide rest area adjacent to the walk at convenient intervals with space
for bench seats. For comfort the seat should be between 350 mm-425 mm high
but not over 450 mm.
- Texture change in walkways adjacent to seating will be
desirable for blind persons.
- Avoid grates and manholes in walks. If grates cannot be
avoid then bearing bar should be perpendicular to the travel path and no opening
between bearing bars should be greater than 12 mm in width.
For parking of vehicles of disabled people the following provisions shall be
a) Surface parking for two care spaces shall be provided near the entrance
for physically handicapped persons with maximum travel distance of 30 m from
b) The width of parking bay shall be minimum 3.60 metre.
c) The information stating that the space is reserved for wheelchair users shall
be conspicuously displayed.
d) Guiding floor materials shall be provided or a device which guides visually
impaired persons with audible signals or other devices which serves the same
purpose shall be provided.
- The main purpose of signs should be to provide a clear
designation of places, warnings and routing information. A person in a wheelchair
is less than 1200 mm high. A person who is partially sighted needs contrasting
texture along side walkways and audible signs for dangerous areas. Signs should
be useful to everyone, easily seen from eye level, readable by moving the
fingers and well lighted for right time identification.
- Signs shall indicate the direction and name of the accessible
facility and incorporate the symbol of access.
- The size, type and layout of lettering on signs shall
be clear and legible.
Signs should be in contrasting colours and preferably be embossed in distinct
relief to allow visually impaired persons to obtain the information they contain
by touching them.
- Simple symbols and contrasting colours which are universally
recognised should be used, for example, green for safety or go, yellow or
amber for risk or caution, and red for danger.

Guiding/warning floor material
The floor to guide visually impaired persons, with a change
of colour or material with conspicuously different texture and easily distinguishable
from the rest of the surrounding floor materials, is called guiding or warning
floor material. The material with different texture gives audible signals with
sensory warning when a person moves on this surface with walking stick. The
guiding/warning floor material is meant to give the directional effect or warn
a person at critical places. This floor material shall be provided in the following
- The access path to the building and to the parking area.
- The landing lobby towards the information board, reception,
lifts, stair cases and toilets.
- Immediately at the beginning/end of walkway where there
is vehicular traffic.
- At the location abruptly changing in level or beginning/end
of a ramp.
- Immediately in front of an entrance/exit and the landing.
- Appropriate identification of specific facilities within
a building for disabled persons should be done with proper signage. Visually
impaired persons make use of other senses such as hearing and touch to compensate
for the lack of vision. Visual signals benefit those with hearing disabilities.
- Signs should be designed and located so that they are
easily legible by using suitable letter size (not less than 20 mm high). For
visually impaired persons, information board in Braille should be installed
on the wall at a suitable height and it should be possible to approach them
closely. To ensure safe walking there should not be any protruding sign which
creates obstruction in walking. Public Address System may also be provided
in busy public areas.
- The symbols/information should be in contrasting
colour and properly illuminated because people with limited vision may be
able to differentiate amongst primary colours. International symbol mark for
wheelchair should be installed in the lift, toilet, staircase, parking areas,
etc, that have been provided for disabled people.
