Accessibility is a fundamental requirement in building design. Buildings must be designed so that people can move safely and independently through spaces, access entrances and exits, use facilities, and navigate circulation routes regardless of mobility limitations. Accessibility requirements apply to entrances, doors, corridors, ramps, stairs, circulation routes, and spaces around objects such as furniture, equipment, and sanitary facilities.
These requirements are often defined in building regulations and accessibility standards and must be considered throughout the design process. Changes to layouts, doors, equipment placement, and circulation routes during design and coordination may affect accessibility requirements and should be reviewed as the design evolves.
Model-based workflows allow accessibility-related design information to be reviewed directly within BIM models, helping project teams identify potential accessibility issues earlier and improve coordination between disciplines.
