The vertical corner posts and the roof corner extrusion shall be mated by a cast aluminum corner cap welded<br />

to all three extrusions inside and out. Construction which merely welds the extrusions together is<br />

unacceptable.<br />

Does your bid comply?<br />

Yes __X__ No_____<br />

Roof<br />

The roof skin shall consist of a single sheet of .090”– 5052-H32 alloy rated aluminum. Roof framing shall be 4”<br />

x 4” tubing with a wall thickness of .125” and an alloy rating of 6061-T6. These beams shall be formed with an<br />

arch to give the roof a minimum of ¾” crown at the center, to prevent pooling of snow/ice/water. They shall<br />

also be engineered and designed with openings for the center wiring harness and, if equipped, for ducting for<br />

overhead HVAC system. These structural tubing members shall be set on 16 inch centers. The roof sheeting<br />

shall not be required as integral part of the roof structure; however, the roof skin shall be welded to the outer<br />

extrusions using a full perimeter, continuous weld on all four sides. The roof structure itself shall be designed<br />

to enhance the safety and structural integrity of the modular body and to meet or exceed the load<br />

requirements of AMD Standard No. 001. A flat roof will not be considered.<br />

Does your bid comply?<br />

Yes __X__ No_____<br />

Horizontal Roof Edge<br />

The extruded roof edge structural members will measure 6" x 4.75" with a 2" radius, a minimum wall thickness<br />

of .125" and an alloy rating of 5052-H32. The roof extrusions will include an integral, full-length drip rail for<br />

each side and from side to side on both the front and rear of the module. Drip rails which are attached to the<br />

roof edge perimeter may not be attached using screws, adhesives, or rivets.<br />

Does your bid comply?<br />

Yes __X__ No_____<br />

Static Load Test<br />

The ambulance body as a unit shall be designed and built to provide impact resistance. The body shall be of<br />

sufficient strength to support a minimum of( 2.5) times the weight of the "fully" loaded vehicle on its top and<br />

side, without crushing, separation of joint or excessive deformation of roof bows, reinforcements, body parts,<br />

doors, floor members, inner linings, outer panels, rub rails or any other structure in accordance with AMD<br />

Standard No. 001.<br />
