Portland Cement: ASTM C 150, Type I. <br />2. Sand: ASTM C 404. <br />3. Water: Potable. <br />E. Gaskets: Dry seal santoprene pressure type. <br />F. Aluminum Flashing: ASTM B 209, Type 3003 H14,0.040 inch, minimum. <br />2.3 FABRICATION <br />A. General: <br />1. Shop Assembly: Assemble components in shop to greatest extent possible to minimize <br />field assembly. <br />2. Welding: In accordance with ANSFAWS D1.2. <br />3. Bent Construction: Factory weld beams to columns with neatly mitered corners to form <br />one -piece rigid bents. Make welds smooth and uniform using an inert gas shielded arc. <br />Perform suitable edge preparation to assure 100% penetration. Grind welds only where <br />interfering with adjoining structure to allow for flush connection. Field welding is not <br />permitted. Rigid mechanical joints may be used only if fully welded bents cannot be <br />shipped on local, state, or federal highways without a special permit from the department <br />of transportation. <br />4. Deck Construction: Fabricate from extruded modules that interlock in a self - flashing <br />manner. Positively fasten interlocking joints at 8 inches on center creating a monolithic <br />structural unit capable of developing the full strength of the sections. The fastenings <br />must have minimum shear strength of 350 pounds each. Assemble deck with sufficient <br />camber to offset dead load deflection. <br />B. Columns: Provide radius - cornered tubular extrusions with cutout and internal diverter for <br />drainage where indicated. Circular downspout opening in column not acceptable. <br />C. Beams: Provide open -top tubular extrusion, top edges thickened for strength and designed to <br />receive deck members in self - flashing manner. Provide structural ties in tops of all beams. <br />D. Deck: Extruded self - flashing sections interlocking into a composite unit. Provide welded plate <br />closures at deck ends. <br />E. Fascia: Manufacturer's standard shape. Provide fascia splices where continuous runs of fascia <br />are jointed. Locate splices to be in line with bents and fasten in place on hidden or non vertical <br />surfaces. <br />2.4 FINISHES, GENERAL <br />A. Comply with NAAMM's "Metal Finishes Manual for Architectural and Metal Products" for <br />recommendations for applying and designating finishes. <br />ALUMINUM WALKWAY CANOPY (Addendum #1) 105305-4 <br />
