Does your bid comply? Yes _X_ No <br />Body Skin Thickness and Allov <br />All sidewall, front and rear panels will be single piece .125" 5052 -H32 aluminum with a minimum density of <br />1.75 pounds per square foot. The single piece body skin shall be attached to the 2" x 2" structural with interval <br />welds spaced at 10 " -12" along the mating edge of each structural tubing member. In addition, the skin shall be <br />bonded to each structural upright full length using high strength Chemrex CX400QT structural adhesive. The <br />body side skin is welded to each corner post along the inside contact point of each corner extrusion. This <br />method of installation provides a welded application to the entire perimeter of the body side skin, a bonded <br />attachment to the wall substructure and an additional flexible adhesive bond for enhanced support. <br />Alternative bonding methods that utilize liquids, caulks, tape or rivets as an attachment process for bonding <br />the side skin to the body structure will not be acceptable. <br />Does your bid comply? Yes _X_ No <br />Body Structural Framing <br />All framing will be a minimum of 2" x 2" square tubing with a wall thickness of .125" and an alloy rating of <br />6061 -T6. Tubing members will be spaced on a maximum of 12 -inch centers for optimum load and structural <br />support. Gussets shall be added at all stress points. Gussets will be either .250" plate or 2" square tubing <br />welded to the adjacent structural members at 45- degree angles for diagonal strength. <br />Does your bid comply? Yes _X_ No <br />Vertical Corner Posts <br />As a part of the inherent structural strength of the modular unit, the use of reinforced extruded corner post is <br />required. The vertical posts will have a minimum wall thickness of .125" and will have an alloy rating of 5052 - <br />H32. The extrusion shall have full - length slots for insertion of the exterior wall skin. This characteristic <br />eliminates exposed panel edges and with the added benefit of seam sealed joints, reduces oxidation and <br />corrosion. The slot provides an area on the inside of the extrusion /sheet junction for welding the body side <br />skin to the corner extrusion. Additionally, the extrusion shall incorporate a full - length, integrally extruded <br />center reinforcement rib with a minimum thickness of .200 inches and two side flanges. Bidder must be <br />prepared to verify compliance with this section. Drawings and samples of actual materials used may be <br />required. The lower ends of the vertical corner posts must be closed off with an aluminum plate. <br />38 <br />Attachment number 1 <br />F -2 Page 86 <br />
