Should disability become an obstacle to success?
“Disability need not be an obstacle to success. I have had motor neurone disease for practically all my adult life. Yet it has not prevented me from having a prominent career in astrophysics and a happy family life.”

UN definition of Disability
“Persons with disabilities include those
who have long term physical, mental, intellectual or sensory impairments which in interaction with various
barriers may hinder their full and effective participation in society on an equal basis with others.”
Disability and Indian Constitution
The
Constitution of India
resolves to secure to all its citizens
justice; liberty; equality; and fraternity.
Citizens with Disability are an essential part of human diversity.
Article 15 of the Constitution ensures the Right of Social Equality and Equal Access to Public Areas
Accessibility for all is recognised as a basic necessity and there are attempts all over
the world to ensure this. Barrier-free features are now becoming
fundamental to all design concepts.
What is a Barrier-Free Environment?
A barrier-free environment is a space that allows for free and safe movement, function and access for all, regardless
of age, sex or condition.
OR
Space or a set of services that can be accessed by all, without obstacles, with dignity and with as much
independence as possible.
Who all face barriers?
Wheelchair users
People with limited walking/ movement abilities
People with visual impairment or low vision
People with hearing impairment
Elderly and infirm persons
Pregnant ladies
Children
People with temporary disabilities
Is it necessary to remove barriers?
• Barriers make an environment unsafe and cause a high level of difficulty to the user.
• Barriers cause spaces to be out of reach, denying people the opportunity of participation in various spheres of life.
• This ranges from education, economic, social, cultural and many other activities.
• This loss of opportunity is not only a loss for the person concerned but also society’s loss which misses out on their contribution.
• A barrier causes exclusion
Access is a basic right
• A barrier-free environment is a basic right of all. It is not a matter of choice or option or be an aspect of sympathy.
• Not allowing a person equal opportunities and participation is an infringement on his/ her rights as a citizen of this country.
• Barrier-free design, therefore, is a professional obligation as well as a societal commitment of design professionals.
Architect’s Viewpoint: Balkrisna Doshi
“A universal design, not remaining synonymous only with the provision of ramps, involves many more aspects
to consider. This neither implies an additional demand nor involves an extra cost, if integrated right from the
conception of the design”
Architect’s Viewpoint: Hasmukh C. Patel
“We, as committed and concerned professionals, should take up this responsibility of addressing these issues and demonstrate through our work the benefits of a barrier-free environment.
Access to public areas is not only a matter of dignity but also the fundamental right of every person in our country”

LET OUR ESTEEMED EXPERTS
GUIDE US HENCEFORTH
Site Development: Walks
• Public Walks be at least 1200mm wide• Gradient not greater than 1 in 20. • Non-slip surface and have level surfaces at regular
intervals• Be of a continuing common surface not interrupted by
steps or abrupt changes in level. • Wherever walks cross other walks, driveways or parking
lots they should blend to a common level.
Passages
• The minimum clear passage width for a single
wheelchair is 900 mm continuously.
• An accessible route should be 1200 mm wide to allow
both a wheelchair and a walking person
• The minimum passage width for two wheelchairs to pass side by side is 1500 mm.Preferable width is 1800 mm.
Site Development: Parking
• Parking lots to be closest to the areas accessible to the handicapped
• Design the spaces so that wheelchairs and individuals using braces and crutches are not compelled to wheel or walk behind parked cars.
• Parking bays should be 2.7 to 3.0m wide
Parking Bays with Aisle space
Ramps
For shorter distances Minimum Width 900mm
Gradient greater than 1 in 20 or maximum of 1 in 12 for short distance up to 900mm.
900mm.
High Handrails preferably on two sides, extend 300mm beyond the top and bottom of the ramp.
Where major traffic is predominantly children, the height of handrails should be restricted to 760mm.
Level platforms at 10 m to 12m intervals. At turnings min. width- 1.5
Minimum width - 1500mm, If length exceeds 3.5m.
The Ramp shall have a level platform at the top which is at least 1800mm long, if a door swings out onto the platform or toward the ramp. This platform shall extend at least 300mm beyond each side of the doorway
Each ramp shall have at least 1800mm of straight clearance at the bottom.
For visually impaired people, ramps may be colour contrasted with landing.
Ramps
Buildings: Entrances
At least one primary entrance to each building to be wheelchairs usable and to be indicated by a sign and shall be
on a level that would make the elevators accessible.

frame. • Height of door handles and locks - 800mm from the floor.
Doors: Kick Plate & Colour Band
Buildings: Windows
