HomeMy WebLinkAbout003 - A002 - 2009 ICC ANSI A A117.1THE FOLLOWING SECTION OF DETAILS PROVIDES INFORMATION ON RESOURCES AND
REQUIREMENTS FOR DISABLED ACCESSIBILITY. THE REQUIREMENTS COMBINE MINIMUM
REQUIREMENTS OF LOCAL, STATE, AND FEDERAL AGENCIES.
THE PURPOSE OF THIS SECTION IS TO HELP AVOID INSTALLATION OF MATERIALS ON
CONSTRUCTION PROJECTS THAT WOULD LIMIT ACCESSIBILITY.
THE SCOPE OF THIS SECTION IS LIMITED AND THE INDIVIDUALS WORKING
ON THE PROJECT SHOULD FAMILIARIZE THEMSELVES WITH LOCAL ACCESSIBILITY
STANDARDS (2009 ICC/ANSI A117.1) AND AMERICAN WITH DISABILITIES ACT ACCESSIBILITY GUIDELINES
(ADAAG) FOR ADDITIONAL INFORMATION AND REQUIREMENTS. COPIES OF THESE
DOCUMENTS MAY BE OBTAINED BY CONTACTING THE FOLLOWING:

IN THE EVENT THE INFORMATION ON THE PLAN SHEETS DOES NOT MEET THE MINIMUM
REQUIREMENTS OF THE SECTION, THEN THE INFORMATION SHALL BE PRESENTED TO THE
ARCHITECT FOR CLARIFICATION PRIOR TO CONSTRUCTION OF SPECIFIC AREA OF WORK.
UNIFORM FEDERAL ACCESSIBILITY STANDARDS (ADA)
In accordance with accessibility requirements, the following standards shall be included when
bidding on projects involving renovations of or new facilities for public accommodation or
commercial facilities. Any items not conforming to these or any other standards, codes, or
ordinances shall be brought to the attention of the project architect for his interpretation. In the
event the information listed in this document conflicts with any portion of the work described in
the Contract Documents, the contractor shall notify the Architect, in writing, of his need for a
solution to resolve the conflict. The mounting heights indicated are for items that require
accessibility by disabled individuals. Where two or more items are grouped in one area (mirrors,
sinks, toilets drinking fountains,urinals, shelves, telephones, etc.) not all items in area have to be
mounted at handicap height. Mounting heights of items where more than one is furnished in a
particular space shall be determined by the Architect in field. These will not furnished in a particular
space shall be determined by Architect in field. be installed at H.C. height. Contractor to
coordinate
these installation heights with other materials for neat, trimmed out and finished appearance. Items
for disabled individual use shall be mounted at height indicated for grade level / age level as noted.
1.DOORS AND OPENINGS
A.Raised Thresholds and Floor Level Changes at Doorways:
Changes in level at doors shall not exceed one-half inch (1/2") in height and shall be beveled
with a slope no greater than 1:2. (ICC/ANSI A117.1, Section 303)
B.DOOR HARDWARE
Handles, pulls, latches, locks, and other operating devices on doors shall have a shape that is
easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting to
operate. The force required to activate door hardware shall be no greater than five lbs.
Acceptable designs include lever-operated mechanisms, push-type mechanisms, and U-shaped
handles. When sliding doors are fully open, operating hardware shall be exposed and usable
form both sides. Doors to hazardous areas such as loading platforms, boiler rooms, mechanical
and electrical rooms, stage, and other areas that might be dangerous to a blind person, shall be
made identifiable to the touch by a textured surface on the door handle, pull, or other operating
hardware. This textured surface may be made by knurling or roughening (no tape allowed). Such
textured surfaces shall not be provided for emergency exit doors or any doors other than those to
hazardous areas. (ICC/ANSI A117.1, Section 404.2.6)
C.DOOR CLOSER
If a door has a closer, then the sweep period of the closer shall be adjusted so that from an
open position of: (a) 90 degrees, the time required to move the door to a position of 12 degrees from
the latch is 5 seconds minimum. (ICC/ANSI A117.1, Section 404.2.7.1)
D.DOOR OPENING FORCE
The maximum force for pushing or pulling open a door shall comply with this paragraph. For
hinged doors, the force shall be applied perpendicular to the door at the door opener or 30
inches from the hinged side, whichever is further from the hinge. For sliding or folding doors,
the force shall be applied parallel to the door at the door pull or latch.
(1) Interior hinged doors shall not exceed 5.0 lb (22.2N) maximum.
(2)Sliding doors or folding doors, and interior hinged doors shall not require a force
exceeding 5.0 lb (22.2N) maximum.
(3)Fire doors may be adjusted to meet the minimum opening force allowed by the
governing authority or applicable building code.
(ICC/ANSI A117.1, Section 404.2.8)
2.CONTROLS AND OPERATING MECHANISMS
A.All controls and devices having general use mechanical or electrical operating mechanisms
which are expected to be operable by occupants, visitors, or other users of a building or
facility, shall comply with this subsection. Such mechanisms may include, but are not
limited to, thermostats, light switches, alarm activating units, ventilators, electrical outlets,
paper towel dispensers, etc.
(1)Clear Floor Space:
A clear floor space that allows a forward or parallel approach by a person using a
wheelchair shall be provided at all controls, dispensers, receptacles, and other
operable equipment. The space shall never be less than an area 30 x 48 inches.
(2)Height:
The highest operable part of any control, dispenser, receptacle, and other operable
equipment shall be no higher from the floor than heights indicated on attached
sketches for forward and side approach except where the use of special equipment
dictates otherwise. Electrical and communications systems receptacles on walls
shall be mounted no less than fifteen inches (15") above the floor.
(3)Operation:
Controls and operating mechanisms shall be operable with one hand and shall not
require tight grasping, pinching, or severe twisting of the wrist. The force required
to activate controls shall be no greater than 5 lb/ft. Hand operated metering faucets shall
remain open for 10 seconds minimum.
3.SIGNAGE
A.Wherever signage is used for emergency information or general circulation directions or
for the identification of rooms and spaces, at least one unit of signage shall be provided
for each function and each room or space that is identified.
(1)Character Proportion:
Letters and numbers on signs shall have a width-to-height ratio between 3:5 and 1:1,
and a stroke width-to-height ratio between 1:5 and 1:10, using an upper case "X" for
measurement.
(2)Color Contrast:
Characters and symbols shall have contrast with their background.
(3)Tactile Characters and Symbols:
Characters, symbols, or pictographs on signs required to be tactile, shall be raised
1/32 in. minimum. Letters and numbers shall be Sans Serif characters; shall be at
least 5/8 in. high, but should be no higher than 2 in.; and shall be proportioned in
accordance with subparagraph 3.A.1 above.
(4)Mounting Height and Location:
Room identification signs shall be mounted on the wall surface on the latch (strike)
side of doors shall be 60 in. (60") above the finish floor to the centerline of the sign
and 8 in. (8") max. from the outside edge of the door frame.
(5) Braille shall be positioned below the corresponding text in accordance with
Sections 703.3 and 703.4
