The persons with disabilities are very much an important part of our society and it’s the moral, social and legal responsibility of The AEC Associates Architectural CAD Drafting to design buildings and facilities that could be used by these people without any hazard or discomfort. Designing for disabled is a very vast subject; we will just concentrate on explaining how Architectural CAD drafting can design accessible doors for them in this post. We will first take a look at the problem areas and then provide tips and solutions.
It’s important for Architectural CAD drafting to avoid some common mistakes that make it difficult for the disabled to use the doors of a public or private building. Here are some of these common problems:
- Narrow doors prohibiting wheelchairs to pass through
- Doors hinged on the wrong sides hindering accessibility and offering health hazard
- Doors with thresholds offering a stumbling block to the disabled
- Doors too heavy or difficult to operate.
Architectural CAD drafting must take into consideration the following design parameters while designing doors of buildings and facilities so that persons with disabilities may find them convenient to use.
- A single person should be able to use the door in a single motion without any difficulty.
- Power-operated doors are best suited. The activator system should either be automatic or easily accessible.
- An accessible door should be fitted with a sign, a Door handle, an extra pull handle, glazing and a kick plate.
- Two types of automatic doors may be used for the convenience of disabled persons- swinging and sliding. Sliding doors are better since they pose no threat to the people at the other end.
- An adequate opening interval should be provided for these doors.
- The doors should allow the wheelchairs to pass through.
- The door opening should be minimum 0.90m for main doors when open.
- Minimum opening for the wash room doors should be 0.76m.
- The minimum clear width of at least one leaf should be 0.80m when double leaf doors are used.
- Guard rails should be provided near double swinging doors to prevent them from hitting people.
