It is the moral, social, and in many cases, legal responsibility of The AEC Associates 3D CAD Design Services to cater to the special needs of the persons with disabilities (PWD) while designing buildings and facilities. The PWD form an important part of the society, they can live a normal life and perform to their potential if 3D CAD design services consider their needs and requirements and provide an enabling environment to allow them to move and work without any physical obstructions or hazards. Our previous week’s discussion is continued here, we will list the types of disabilities and the steps to be taken by the designers to ensure accessibility for everyone.
Types of disabilities
3D CAD design services must be aware of the different types of disabilities they have to cater for in order to provide an accessible environment for the disabled. These may be categorized as follows:
- Wheel chair bound persons
- People with limited walking abilities (those using crutches etc)
- The sightless
- The partially sighted
- The hearing impaired
Different requirements of different people:
Different kind of PWD have different sets of requirements, the design considerations to cater for their needs are also different. While a wheel chair user would need a ramp to move between various floor levels, a staircase would be a better option for a person using crutches,. Sightless people need a tactile sign and sound based systems to conveniently know the number of the floor and their exact location, but visual signs are more appropriate for the hearing impaired for the same purpose.
3D CAD design services must give special consideration to the special needs of different types of the persons with disabilities in order to be able to provide them with an enabling environment. This would allow these people to live a normal life and use different buildings and facilities without any obstacles or physical hazards.
