American Response Vehicles <br />Bostik Brand, Simson ISR 70-03 Construction Adhesive. <br />SIDE IMPACT RAILS: There will be four side impact rails, located in the upper and lower sections of the <br />side walls. They will consist of 6105-T6 aluminum, that is a solid one-half inch thick by four -inch plate <br />on the curbside and one-half by four inch plates on the streetside that are continuously MIG welded or <br />Huck structurally fastened to the structural grid. Since this is a safety item, no exceptions will be <br />accepted. <br />SEAT BELT ANCHORAGE: Occupant seat belts will be drilled and tapped through one-half by four inch plate on <br />the curbside and one-half by four -inch plates on the streetside that are continuously MIG welded to the <br />structural grid. Since this is a safety item, no exceptions will be accepted. <br />SIDE SHEET: The side sheet will be .125 thick, 5052-H32 aluminum. The side sheet compartment <br />opening cut outs will be cut with CNC controlled, gantry mounted plasma or high-speed routing <br />equipment. The door opening will be cut to allow for the skin to be molded into the jamb opening to <br />create a crevice free jamb with a smooth paint finish. The machine formed skin will return into the <br />body at least 3/4" to meet the jamb extrusion. This method will encourage square openings to receive <br />the door assemblies and maintain critical structural locations. The door jamb will have a full structure <br />frame behind the jamb skin return. It will not rely strictly on the skin for the compartment jamb. <br />Pre -determined ventilation louvers will be formed into the body sheet, where specified. Bodies that do <br />not incorporate formed louvers have the potential for additional corrosion points and are not preferred <br />by this agency. <br />SEAMLESS DOOR JAMBS: The door jambs of the module will be seamless. A seamless door jamb <br />exterior is required to minimize corrosion. Extruded type exposed door jambs do not meet this <br />specification. The skin will completely conceal the door -jamb from view. The only visible seams on the <br />body sheet will be at the corner posts. The skin will extend .688 inch below the skirt rail extrusion to a <br />drip edge to keep moisture from collecting underneath where the skin meets the skirt rail extrusion. <br />CORNER POST EXTRUSION: The corners of the modular body will be made from an extruded <br />aluminum structure that has an alloy of 6105-T6. The corner post extrusion will be 3.25 x 3.25-inch <br />with a 2-inch- radius on the outer corner. The corner post extrusion will have an internal web member <br />that runs on a 45-degree angle to the front and side of the modular body. Where the internal web <br />meets the exterior extrusion wall the internal web will flair into a .125-inch radius giving a .25-inch <br />wall thickness at the exterior wall of the extrusion. There will be a .75-inch flange on each side of the <br />corner post extrusion that is a side skin receiver. The side skin receiver will be funnel shaped to allow <br />the exterior side skin to fully seat into the corner post extrusion. The interior walls of the corner post <br />extrusion will be .125-inch thick, and they will incorporate a 45-degree weld bevel on the interior <br />corners. <br />REAR SILL EXTRUSIONS: The rear body and floor substructure will be constructed of a dual proprietary <br />aluminum extrusion with mating joints. The lower floor extrusion is a combination continuous <br />0 <br />
