7 Chapter 3 - Building Blocks The provisions of Chapter 3 shall apply where required by Chapter 2 or where referenced by a requirement in this document (301.1).
8 What are Building Blocks? Defined as: “Elements or components contributing to a plan or system.”308 Reach Ranges309 Operable Parts307 Protruding Objects302 Floor or Ground Surfaces303 Changes in Level304 Turning Space305 Clear Floor or Ground Space306 Knee and Toe ClearanceThe components of Chapter 3 create the basic system for building accessible rooms, elements, and spaces.
9 302 Floor or Ground Surfaces Technical: 302302 Floor or Ground Surfaces
10 Floor or Ground Surfaces 302.1 GeneralFloor or Ground SurfacesFloor or ground surfaces shall be stable, firm, and slip resistant and shall comply with 302.The following excerpts from Advisory address the minimum requirements for stable, firm, and slip resistant surfaces.
11 What is a stable surface? One that remains unchanged by contaminants or applied force, so that when the contaminant or force is removed, the surface returns to its original condition.Grass and sod surfaces are not prohibited, however, they typically will not meet this criteria.
12 do not meet this criteria. What is a firm surface?One that resists deformation by either indentations or particles moving on its surface.Soft or loose materials such as sand, gravel, bark, mulch, or wood chips surfacesdo not meet this criteria.
13 What is slip resistance? One that provides sufficient frictional counterforce to the forces exerted in walking to permit safe ambulation.Slip resistance is the most controversial and difficult to measure since there are many types of surfaces and testing methods and compliance is applicable when wet or dry.In 2009, the National Floor Safety Institute issued the ANSI/NFSI B101.1 which is a new national safety standard for testing dry, hard surfaces.
14 It was recommended to DOJ that they apply an American Society for Testing & Materials (ASTM) standard (with modifications) to the 2010 SAD to assess whether or not a floor surface is "slip resistant”…DOJ declined the recommendation since there is no generally accepted test method for the slip-resistance of all walking surfaces under all conditions.
15 However, DOJ did include ASTM standards in the 2010 SAD applicable to safe surfaces under and around playground equipment.ASTM standards are referenced in:(Referenced Standards)(Play Areas: Ground Surfaces)
16 “ADA /TAS – Seal of Approval”? What surfaces have the“ADA /TAS – Seal of Approval”?ADA-ApprovedNone…neither DOJ nor TDLR endorses or approves any products or manufacturers.ADA-CertifiedTAS-CompliantCompliance is typically dependent on theinstallation and maintenance.
17 (Concrete with small pebbles) Example:Exposed Aggregate(Concrete with small pebbles)Some factors that affect compliance with 302:Size of aggregateTamping and leveling of the aggregate
18 302.1 Floor or Ground Surface Exception 1Within animal containment areas, floor and ground surfaces shall not be required to be stable, firm,or slip resistant.Not applicable to public circulation routes where animals may travel, such as in petting zoos (Advisory ).

23 Roll Resistance Carpets and permanently affixed mats can significantly increase theamount of force (roll resistance) needed to propel a wheelchair over a surface (Advisory 302.2).The firmer the carpeting and backing, the lower the roll resistance (Advisory 302.2).
24 No longer called “gratings” 302.3 OpeningsNo longer called “gratings”Openings in floor or ground surfaces shall not allow passage of a sphere more than ½” diameter except as allowed.Elongated openingsshall be placed so that the long dimension is perpendicular to the dominant direction of travel.
