Transcript Guide to The New ADA-ABA Accessibility Guidelines

2004 Changes to
ADA-ABA
Accessibility Guidelines
Alberto Garcia-Paz
Lexander Reina
U.S. ACCESS BOARD
An independent Federal Agency
Develops
Updates
accessibility guidelines for new or
altered facilities covered by ADA,
ABA, in both public and private
sectors.
GUIDELINES
BACKGROUND
•Americans with Disabilities
Act (ADA) 1990
•The Architectural Barriers Act
(ABA) 1968
GOALS OF THIS UPDATE
• Update specifications to continue to meet
the needs of persons with disabilities.
• Improving the format and usability of the
guidelines to facilitate compliance.
• Harmonizing the guidelines with model
building codes and industry standards.
• Making the requirements for ADA and ABA
facilities consistent.
When will the new guidelines take
effect?
• The Board’s guidelines are not mandatory on the public, but
instead serve as the baseline for enforceable standards
(which are) maintained by other Federal agencies. In this
respect, they are similar to a model building code in that they
are not required to be followed except as adopted by an
enforcing authority. Under the ADA, the Department of Justice
(and in the case of transit facilities, the Department of
Transportation) are responsible for enforceable standards
based on the Board’s guidelines. These agencies will update
their ADA standards based on the new guidelines. In doing so,
they will indicate when the new standards are to be
followed. Several other agencies (the General Services
Administration, Department of Defense, Department of
Housing and Urban Development, and the U.S. Postal Service)
hold a similar responsibility for standards used to enforce the
ABA.
Organization and Format
The updated guidelines feature:
• a new numbering system consistent with model
codes
• a more streamlined structure and organization of
chapters
• updated scoping and technical provisions, with a
greater structural delineation between them
• new figures and commentary (advisory
information)
• provision of all figure-based information in written
text
Supplements to ADAAG
• The Board previously developed supplements to
the original ADA guidelines that are specific to
different types of facilities and elements:
• state and local government facilities, including
courthouses and prisons (1998)
• building elements designed for children’s use
(1998)
• play areas (2000)
• recreation facilities (2002)
• These supplements are included in the new
guidelines. They have been revised for
consistency with the format and approach of the
new document, but their substance remains
unchanged.

CHAPTER 4: ACCESSIBLE ROUTES
401 General
402 Accessible Routes
403 Walking Surfaces
404 Doors, Doorways, and Gates
405 Ramps
406 Curb Ramps
407 Elevators
408 Limited Use/ Limited Application Elevators
409 Private Residence Elevators
410 Platform Lifts
Change in 180-degree Turn
Clear Space at Recessed Doors
Clarification of Consecutive Doors
405.2 Maximum Ramp Slope and Rise for Existing Sites, Buildings, and Facilities
Slope1
Maximum Rise
Steeper than 1:10 but not steeper than 1:8
3 inches (75 mm)
Steeper than 1:12 but not steeper than 1:10
6 inches (150 mm)
A slope steeper than 1:8 is prohibited.
• Advisory 405.7 Landings. Ramps that do
not have level landings at changes in
direction can create a compound slope
that will not meet the requirements of this
document. Circular or curved ramps
continually change direction. Curvilinear
ramps with small radii also can create
compound cross slopes and cannot, by
their nature, meet the requirements for
accessible routes. A level landing is
needed at the accessible door to permit
maneuvering and simultaneously door
operation.
EXTENDED FLOOR or GROUND:
Edge Protection
• 410.6 Doors and Gates. Platform lifts shall
have low-energy power-operated doors or
gates complying with 404.3. Doors shall
remain open for 20 seconds minimum. End
doors and gates shall provide a clear width
32 inches (815 mm) minimum. Side doors
and gates shall provide a clear width 42
inches (1065 mm) minimum.
• EXCEPTION: Platform lifts serving two
landings maximum and having doors or
gates on opposite sides shall be permitted to
have self-closing manual doors or gates.
CHAPTER 5: GENERAL SITE AND
BUILDING ELEMENTS
501 General
502 Parking Spaces
503 Passenger Loading Zones
504 Stairways
505 Handrails
Accessible Van Space
Access Path Width
Larger and Different Handrail Shapes Allowed
Advisory 505.4 Height. The requirements for stair
and ramp handrails in this document are for
adults. When children are the principle users in
a building or facility (e.g., elementary schools),
a second set of handrails at an appropriate
height can assist them and aid in preventing
accidents. A maximum height of 28 inches (710
mm) measured to the top of the gripping
surface from the ramp surface or stair nosing is
recommended for handrails designed for
children. Sufficient vertical clearance between
upper and lower handrails, 9 inches (230 mm)
minimum, should be provided to help prevent
entrapment.
