2010 Standards for Accessible Design Presented by Ray Petty Great Plains ADA Center Wichita, Kansas May 24, 2012
Update on DOJ’s ADA Standards • Published in the Federal Register as a Standard September 15, 2010 Effective 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
Side-by-side Comparisons New ADAAG, original ADA standards, and IBC/ ANSI www.access-board.gov/ada-aba/comparison/comparison.pdf
CHAPTER 1 Application and Administration 101 – Purpose 102 – Dimensions for Adults and Children 103 – Equivalent Facilitation 104 – Conventions 105 – Referenced Standards 106 – 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) • elevators and lifts (ASME A17.1 & A18.1) • egress (IBC) • alarms (NFPA 72) • play surfacing & equipment (ASTM standards)
Application (201) Premise: All areas of newly designed/ constructed facilities are to comply, unless indicated Exceptions more thoroughly covered
Existing Buildings and Facilities (202) • Additions • Alterations (specific exceptions now located at relevant provision) • Primary Function Areas – Path of Travel • Qualified Historic Facilities
ABA Application & Scoping (Chapters F1 & F2) Consistent with ADA document except for: • modifications and waivers (F103) • definitions (F106) • additions (F202.2) • leased facilities (F202.6) • employee work areas (full coverage) • existing elements (F203.2)
General Exceptions (203) • construction sites • raised areas • limited access spaces • machinery spaces • single occupant structures (e.g., toll booths) • certain common use spaces in detention and correction facilities and residential facilities • employee work areas • various spaces in recreation facilities
ADA Work Areas • “approach, entry, & exit” • circulation paths (in areas ≥ 1000 sq ft) • means of egress • visual alarm • connection
ADA Employee Work Areas Circulation paths = accessible unless: • Work areas < 1000 sq. ft. defined by permanent partitions, casework, counters, or furnishings • Paths, when integral part of equipment • exterior areas fully exposed to the weather
Building Blocks (Chapter 3) • Floor or Ground Surfaces • Changes in Level • Turning Space • Clear Floor/ Ground Space • Knee & Toe Clearance • Protruding Objects • Reach Ranges • Operable Parts
Turning Space (304) • clarification: overlap of turning space is allowed where knee/ toe clearance is provided • doors can swing into turning space
Turning Space (304) Overlap permitted for only one arm of T-shaped space
Reach Ranges (308) Max. Reach – 48”Min. Reach – 15”(forward & side)
Operable Parts (205) New or clarified exceptions for: • those used only by maintenance personnel • elec./ comm. receptacles – dedicated use • floor electrical receptacles • certain additional outlets above counters • HVAC diffusers • Redundant controls (except light switches)
Accessible Routes (Chapter 4) • Accessible Route Components • walking surfaces • doors, doorways, gates • ramps • curb ramps • elevators • limited use/ limited application elevators • private residence elevators • platform lifts
Accessible Routes (206) Where required: • Site arrival points • Within sites (but not required if no pedestrian route is provided) • Between stories (elevator exceptions) • Space and elements • Specific spaces (e.g., restaurant & cafeteria, performance area, press box)
Press Boxes New exception: • if 500 sq ft or less (aggregate area) • on bleachers entered on 1 level • free-standing – elevated 12’ or more
Entrances Route to entrances to coincide with general circulation routes to maximum extent feasible
Entrances Communication devices should have both visual and audible signals (Required in new version)
Walking Surfaces (403) (Portions of accessible routes that slope no more than 1:20) • Minimum separation (48”) between reduced clear widths • Handrails along walking surfaces are required to comply
Doors - Clearances Clearance at doors in thick walls or that are recessed (8” max. offset) Pull side clearance, forward approach
Doors - Clearances Push side clearance required at doors with both closer & latch
Doors, Doorways, & Gates (404) Other changes: • Doors in series • Hardware height • Limited projections into clear width • Closing speed • Surface (push side) • Vision lights
Doors in Series New version allows both sets of doors to swing into space (with proper separation)
Doors in Series Where doors are automated, provide wheelchair space at controls outside door swing
Entrances • Automated openers recommended for exterior doors • Required for Federal GSA buildings
