ARCHITECTURAL SPECS Part 1 — General 1.1 DESCRIPTION OF PRODUCT a. The product described herein,manufactured by EZ-ACCESS('manufacturer'),is an aluminum modular ramp consisting of ramp sections,platforms,rails,and supports that are selected to provide adequate ramping height. 1.2 QUALITY ASSURANCE a. The ramp may be subject to state,local,and city approval prior to installation and subject to inspection after installation. 1.3 REFERENCE CODES a. Americans With Disabilities Act Handbook(published by the Equal Employment Opportunity Commission and the U.S. Department of Justice,publication EEOC-BK-19). 1.4 SUBMITTALS a. Shop drawings by contractor or manufacturer's literature for approval.Drawings shall indicate layout,unit locations, unit identification,connections details,support items,and dimensions. b. A sample of the ramp treads showing slip resistant ramp surfaces. 1.5 DELIVERY AND HANDLING a. The contractor shall inspect the components upon delivery to ensure that the proper materials have been received and are not damaged or defective. Damaged or defective materials shall be removed from the site. 1.6 FIELD MEASUREMENTS a. Verify that field measurements are as indicated on the placement of plans. 1.7 WARRANTY—LIMITED LIFETIME a. The manufacturer shall have in writing a limited lifetime warranty against any defect in materials and workmanship. Part 2 — Overview 2.1 OVERVIEW a. All PATHWAY 3G ramps and accessories shall be prefabricated modular units as manufactured by EZ-ACCESS.These ramps shall be modular in design to allow for easy of assembly and relocation. 2.2 RAMPS a. ENGINEERING 1. Ramp sections shall be designed to 2018 International Residential Code(IRC)with a minimum uniform live load of 40 lbs.per square foot(PSF)and a concentrated vertical load of 300 lbs. b. MATERIALS 1. Ramp sections shall be constructed using 6000 series aluminum alloy with 6061-T6 or 6005-T5 used for structural components. 2. All structural fasteners which attach ramps together and handrails to ramps shall be of grade 5 strength or higher and shall be zinc plated or zinc chromate finish. c. DESIGN AND FABRICATION 1. PATHWAY 3G ramp units are to be built to shape,size,and finish as indicated on approved drawings. 2. Ramp surface is to be continuous,that is no gaps greater than%", and shall have an extruded slip resistant surface. Platform deck surface will be knurled to make slip resistance bi-directional. 3. Ramps shall be constructed of either interlocking 1.125"x 6"treads welded to side rails, or.5"-.125" standard expanded metal (EM)welded to a tubular support frame which connects side rails. 4. All ramp sections shall have a 2" minimum curb height. 5. Top of all ramps must accept a full width pivoting top adapter plate with a minimum 3" extension with a preformed angle between 8°and 12°with a slip resistant surface. 6. Bottom of all ramps must accept a full width pivoting bevel with a slip resistant surface from ramp to ground transition. 7. All fasteners shall be captured either on outside of ramp or underneath. 8. There shall be no fasteners protruding into the inner usable ramp or curb surface. 2.3 PLATFORMS a. ENGINEERING 1. Platforms sections shall be designed to 2018 International Residential Code(IRC) with a minimum uniform live load of 40 lbs. per square foot(PSF) and a concentrated vertical load of 300 lbs. b. MATERIALS 1. Platform sections shall be constructed using 6000 series aluminum alloy with 6061-T6 or 6005-T5 used for structural components. c. DESIGN AND FABRICATION 1. Platform units are to be built to shape,size,and finish as indicated on approved drawings. 2. Platform surface is to be continuous,that is no gaps greater than %", and shall have an extruded slip resistant surface, knurled to make slip resistance bi-directional.
