B. Substitutions: Any substitution must comply with the pre-bid submittal as discussed in the<br />

Submittal section 1.03. No post-bid substitutions are allowed.<br />

1. Any proposed system shall be approved and compatible with adjacent materials and<br />

components such that the assembly as a whole will conform to this specification, and<br />

shall include an extruded aluminum perimeter to provide the designed architectural<br />

reveal and guttering system without the use of external field applied sealants. Any<br />

substitution must also comply with the System Description Section 1.02 and meet or<br />

exceed the performance requirements as described in the Testing Section 1.05 without<br />

the reliance of a secondary backup membrane.<br />

C. Code Performance Requirements: Work of the section shall conform to all applicable codes<br />

and regulations.<br />

1. Thermal Design Criteria:<br />

a. Make allowances for free and noiseless vertical and horizontal thermal<br />

movement due to the contraction and expansion of component parts, for an<br />

ambient temperature range from -20 degrees F to +180 degrees F. Buckling<br />

of panels, separation/opening of joints, undue stress on fasteners, failure of<br />

sealants or any other detrimental effects due to thermal movement of<br />

component parts will not be permitted. Fabrication, assembly and erection<br />

procedure shall take into account the ambient temperature range at the time of<br />

the respective operation.<br />

2. Wind Loads:<br />

a. Assemblies herein specified shall be designed for flexural, shear and torsional<br />

stresses for the following positive and negative wind pressures acting normal<br />

to the plane of the assemblies. Loading design shall; be based on latest<br />

Building Code but in no case less than 20 pounds per square foot with 25<br />

pounds per square foot corner pressure.<br />

3. Material Stress and Deflection:<br />

a. Normal to the plane of the wall between structural supports, deflection of the<br />

attached perimeter-framing members shall not exceed L/175 of span length or<br />

3/4", whichever is less.<br />

b. At connection points of framing members to anchors, anchor deflection in any<br />

direction shall not exceed 1/16". Where connection points are not clearly<br />

defined, maximum anchor deflection shall not exceed 1/16".<br />

c. Stresses must take into account interaction and in no case shall allowable<br />

values exceed the yield stress.<br />

d. At 1.5 times design pressure, permanent deflections of framing members must<br />

not exceed L/1000 of the span length, and components must not experience<br />

failure or gross permanent distortion. At connection points of framing<br />

members to anchors, permanent set shall not exceed 1/16".<br />

1.05 TESTING<br />

A. Wall System Test Specimen Arrangement: The panel system test specimen must be arranged<br />

with at least four (4) panels. The panel joint arrangement shall consist of intersecting typical<br />

vertical and horizontal joints to generate a typical 4-way intersection and include the design and<br />

materials for the 4-way splice. Testing a 3-way intersection alone is not acceptable.<br />

B. Wall System Performance: Walls furnished under this section shall have been tested. If<br />

comparable tests are not available, mockups shall be constructed and tests performed. In<br />

either case, an independent laboratory approved by the architect shall conduct the tests. Test<br />

results shall meet or exceed the following without reliance on a secondary backup membrane:<br />

1. Air Infiltration:<br />
