Using the ADA and ABA Standards Series: Chapter 3: Building Blocks

Thursday, April 2, 2020
2:30 PM - 4:00 PM Eastern Time Zone


This session will review “Building Block“ provisions in the ADA and ABA Accessibility Standards (Chapter 3) that are the foundation for many technical specifications in standards. These requirements apply to a wide range of elements, spaces, and rooms covered by the standards. They address ground and floor surfaces, clear floor space, knee and toe clearances, turning space, reach ranges, operable parts, and protruding objects. Presenters will address common sources of confusion and frequently asked questions about these provisions.

Questions for presenters:

1 there is always a controversy about ramps is it 30 foot length? or 30 inch rise? A ramp less than maximum rise percentage can have a longer run using the 30" rise criteria, yet many designers limit it to only a 30 foot run
2 Reach range states you can not reach over a surface greater than 34" AFF for side reach per 308.3.2. If I have controls within the front 10" of a horizontal surface at 36" AFF, or 38" AFF, would this be considered within side reach range? I am seeing a lot of confusion on interpretation of unobstructed high reach per 308.3.1 excep 1.
3 An instructor asked for input on how to make his ceramics lab more ADA-friendly, if you happen to have any input on this...
4 Do you have a flow chart of all the agencies and authorities over ADA/ABA? At ASLA we are working on a guide to accessibility for our members as a reference and this would be helpful.
5 5. Vertical grab bars: good practice to provide these?
