Update on DOJ’s ADA Standards

• Published in the Federal Register as a Standard September 15, 2010Effective Dates:

• Sept 15, 2010- Entities may choose either 1991 Standard or the 2010 Standard

• March 15, 2012- 2010 Standard will be the only ADA standard available


Updated DOT Standards for Transit Facilities

Updated ADA standards adopted by DOT (effective Nov. 2006)

Apply to transportation facilities:• Bus stops and stations• Rail stations• Airports


Updated DOT Standards for Transit Facilities

Same as updated ADAAG, except for clarifications/ modifications:

• accessible routes (206.3) • detectable warnings on curb ramps

(406.8) • bus boarding areas (810.2.2), and • rail station platforms (810.5.3).


ABA Standards

• Similar update of Architectural Barriers Act (ABA) standards

• Applies to federally funded facilities

• ADA and ABA guidelines harmonized – updated standards more consistent


Updated ABA Standards

Four agencies maintain ABA Standards:

• GSA - most ABA facilities (May 06)• USPS - postal facilities (Oct 05)• DOD - military facilities (Oct 08)• HUD – housing (update pending)


“What standards do I follow?”

First response remains: What kind of project/ facility is it?


Applicable ADA Standards

• Places of public accommodation, commercial facilities (Title III) and

state & local government facilities (Title II):

DOJ’s updated standards• Transportation facilities: DOT’s updated standards


Updated ADAAG

Application and General Scoping


New Format

• New numbering system

• New figures (informational only)

• All dimensions in text (not just in figures)

• New advisory notes follow provision


ADAAG Supplements

Previous supplements included:• State & Local Gov’t Facilities (1998)• Children’s Environments (1998) • Play Areas (2000)• Recreation Facilities (2002)

These are now integrated into the ADA-ABA Guidelines, now called 2010 Standards.


Harmonization

• ICC/ANSI A117.1-2003 IBC 2003

CHAPTER 1

Application and Administration101 – Purpose102 – Dimensions for Adults and Children103 – Equivalent Facilitation104 – Conventions105 – Referenced Standards106 – Definitions


Conventions

• Dimensions – range instead of absolute dimension where possible

• Construction and manufacturing tolerances

• Calculation of percentages • Figures – are informational; the text

governs!


Ranges instead of absolute dimensions

Water closet centerline (16-18”) Width of ambulatory accessible stall (35”- 37”)


Some absolute dimensions remain

Transfer shower stall (36” x 36”) and combination transfer/roll-in design with seat on front wall (36” deep)

measured to center points; manufacturing tolerances recognized


Conventional Industry Tolerances

For field conditions and manufacturing process (not design work)

• Don’t apply to ranges (min. and max.) • For absolute dimensions or where only a

min. or max. specified• Avoid specifying tolerances (e.g., “36 inches

plus or minus X inches”)• Design should specify above max. or below

min. (to factor in tolerance)


Referenced Standards

• powered doors (ANSI/BHMA A156.10 & A156.19)

standards)
