BARRIER FREE ENVIORNMENT AND DESIGN

1

WHAT IS BARRIER FREE ENVIORNMENT?

Barrier Free Environment is one which enables people with disabilities ,old people , small children to move about safely and freely and to use the facilities within the built environment.

A space or a set of services that can be accessed by all, without obstacles, with dignity and with as much independence as possible. The environment means buildings, roads, parks, gardens and other places, services, modes of transportation, products of daily use, etc.

NEED OF BARRIER FREE ENVIORNMENT

Barriers make an environment unsafe and cause a high level of difficulty to the user. But more importantly, barriers cause spaces to be out of reach, denying people the opportunity of participation in various spheres of life.

The goal of barrier free design is to provide an environment that supports the independent functioning of differently able individuals so that they can get to, and participate without assistance, in every day activities such as procurement of goods and services, community living, employment, and leisure.

CONSTRUCTION AND MAINTAINANCE STANDARDSNon-ambulatory

disabilitiesThe 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)

DESIGN REQUIREMENTS-CINEMA HALL/AUDITORIUM

1.Walks and pathsWalks should be smooth, hard level

surface suitable for walking and wheeling.

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.

Avoid grates and manholes in walks.

2.ParkingFor parking of vehicles of disabled

people the following provisions shall be made:

4.EntranceA)Ramped Approach:

Ramp shall be finished with non-slip material to enter the building.

Minimum width of ramp shall be 1800 mm with maximum gradient 1:12, length of ramp shall not exceed 9.0 metre with 800 mm high handrail on both sides extending 300 mm beyond top and bottom of the ramp.

Minimum gap from the adjacent wall to the handrail shall be 50 mm.


11

B)Exit/entrance Door: Minimum clear opening of the entrance door shall be 900 mm and it shall not provided with a step.

C) Entrance landing: Entrance landing shall be provided adjacent to ramp with the minimum dimensions 1800 mm x 2000 mm.

D)Lifts: a) A hand rail not less than 600 mm long at 1000 mm above floor level shall be fixed adjacent to the control panel.

b) The lift lobby shall be of an inside measurement of 1800 mm x 1800 mm or more.

c) The time of an automatically closing door should be minimum 5 seconds and the closing speed should not exceed 0.25 Metre/Second.

5.Toilets

One special W.C. in a set of toilet shall be provided for the use of handicapped with essential provision of wash basin near the entrance for the handicapped.

a) The minimum size shall be 1500 mm x 1750 mm.

c) Suitable arrangement of vertical/horizontal handrails with 50mm. clearance from wall shall be made in the toilet.

d) The W.C. seat shall be 500 mm from the floor.

6.Seats/Seating Space In Cinema Hall/Auditorium

A minimum of 4 wheelchair spaces for seating capacity from over 100 to 400 seats

Accessible seating spaces should be provided in a variety of locations to give people with disabilities a viewing option.

Some fixed seats will have to be taken off from various locations next to the to provide wheelchair parking space of minimum 750 mm wide by 1200 mm long.

Convenient Place for Seats of disabled peoples is near the entrance and exit.

Mostly seats provided at front rows or back rows.

But why the peoples with disability should always seat at front and back rows.

So design of seating space should be considered in the middle rows.

Level of seats should be increased to improve sightline.

Passage for person with wheelchair should be 1.0m (min)


18

Another option instead of ramp design is Wheelchair Stair lift.

No need of ramp design , less space required.

Railing on one side is required. Can be used on the wall side. It is also a good option for ramp in

auditorium.

Option 4-Wheelchair stair lift
