Architectural barriers remain abundant and often invisible to the general public. Barrier-free design is essential to ensure the health, safety, welfare, and civil rights of building occupants. Square-P® looks at accessibility issues from the beginning to the end of projects and can evaluate existing and potential issues that limit access to a facility. In addition to the 2010 ADA Standards for Accessible Design, there are building code requirements and other regulations that address accessibility. Square-P® is a ready resource for advice about accessible design and code standards.
