Resubmit marked original, calculations and this correction sheet. A separate sheet for response may be used.Resubmit corrected sets of plans.Meetings between the project applicant/designer and the plan reviewer shall be by appointment only. Please call (714) for an appointment.CBC Section 1133B.4.4, Where stairways occur outside a building, the upper approach and all treads shall be marked by a strip of clearly contrasting color at least 2” wide and placed parallel to and not more than 1” from the nose of the step or landing to alert the visually impaired. The strip shall be of a material that is at least as slip-resistant as the other treads of the stair. A painted strip shall be acceptable.Provide handrail details on the drawings showing compliance with CBC Section 1009.10, 1012, and 1133B.4.1. - Stairways shall have handrails on each side. - Every stairway required to be more than 88” in width shall be provided with not less than one intermediate handrail for each 88” of required width. Intermediate handrails shall be spaced approximately equally across with the entire width of the stairway. - Handrails shall be 34 to 38” above the nosing of treads. - Handrails shall extend a minimum of 12” beyond the top nosing, and shall extend a minimum of 12” plus the tread width beyond the bottom nosing. - Ends of handrails shall be returned or shall terminate in newel posts of safety terminals. - Handrails projecting from a wall shall have a space of 1½” between the wall and the handrail. - The handgrip potion of handrails shall not be less than 1¼” nor more than 1½” cross-sectional dimension or the shape shall provide an equivalent gripping surface. The handgrip portion of handrails shall have a smooth surface with no sharp corners. Any wall or other surface adjacent to the handrail shall be free of sharp or abrasive elements. Edges shall have a minimum radius of 1/8”.CBC Section 1133B.4.2.2. Handrails shall extend a minimum of 12” beyond the top nosing and 12”, plus the tread width, beyond the bottom nosing. At the top, the extension shall be parallel with the floor or ground surface. At the bottom, the handrail shall continue to slope for a distance of one tread width from the bottom riser; the remainder of the extension shall be horizontal. See Figures 11B-35 and 11B-37.CBC Section 1009.3.2 Stair treads and risers shall be of uniform size and shape. The tolerance between the largest and smallest riser height or between the largest and smallest tread depth shall not exceed 0.375 inch (9.5 mm) in any flight of stairs. Any accessible route of travel shall be considered a ramp if its slope is greater than 1’ rise in 20’ of horizontal run (5-percent gradient) and show compliance with CBC Sections 1010 and 1133B.5.1. - Pedestrian ramps used as exits shall show compliance with CBC Sections 1010 and 1133B.5. - Provide complete architectural plan views, sections, details, and notes for pedestrian ramps. - An aisle ramp slope in occupancies of Group A shall comply with Section 1025.11. - CBC Sections 1010.3 and 1133B.5.3.1. The slope measured perpendicular to the direction of travelof a ramp shall not be steeper than one unit vertical in 48 units horizontal (2-percent slope). - CBC Sections 1010.4 and 1133B.5.3. The rise for any ramp run shall be 30” maximum. - Refer to the attached pedestrian ramp handout.CBC Section 1010.6.1, Slope. Landings shall have a slope not steeper than one unit vertical in 48 units horizontal (2-percent slope) in any direction. Changes in level are not permitted.CBC Section 1010.6.4, Change in Direction. Where changes in direction of travel occur at landings provided between ramp runs, the landing shall be 60” by 60” minimum. - CBC Section 1133B.5.4.4, Strike edge extension. The width of the landing shall extend 24” past the strike edge of any door or gate for exterior ramps and 18” past the strike edge for interior ramps. - CBC Section 1133B.5.4.9, Hazards. Required ramps shall have a curb at least 2”high, or a wheel guide rail 2 to 4” high on each side of the ramp landing that has a vertical drop exceeding 4” and that is not bounded by a wall or fence.CBC Section 1133B.5.5.1, Handrails for ramps: - Are required on ramps that provide access if the slope exceeds 1’ rise in 20’ of horizontal run (5-percent gradient), except that at exterior door landings - Are not required on ramps less than 6” rise or 72” in length - Shall be placed on each side of each ramp, shall be continuous the full length of the ramp - Shall be 34 to 38” above the ramp surface to the top of the handrails - Shall extend a minimum of 1’ beyond the top and bottom of the ramp and shall be parallel with the floor or ground surface - The inside handrail on switchback or dogleg ramps shall always be continuous - The ends of handrails shall be either rounded or returned smoothly to floor, wall or post - Handrails projecting from a wall shall have a space of 1½” between the wall and the handrail - Handrails may be located in a recess if the recess is a maximum of 3” deep and extends at least 18” above the top of the rail - The grip portion shall not be less than 1¼” nor more than 1½“ in cross-sectional nominal dimension or the shape shall provide an equivalent gripping surface - All surfaces shall be smooth with no sharp corners - Any wall or other surface adjacent to the handrail shall be free of sharp or abrasive elementsCBC Section 1010.8, Handrails. Ramps with a rise greater than 6” shall have handrails on both sides. Handrails shall comply with Section 1012.CBC Section 1133B.5.7, Guards.
