F. Structural Steel
1.05 Submittals
A. Product Data: Submit manufacturer's product information, specifications and installation instructions for building components and accessories.
B. Shop Drawings: Submit complete shop drawings including all necessary plan dimensions, elevations and details. General Contractor shall verify all dimensions and provide mounting height at each aluminum canopy and related struts before releasing to manufacturer for fabrication.
C. Certification: Submit design calculations signed by a Registered Professional Engineer, licensed in the project state. Design calculations shall state that the protective aluminum cover system design complies with the wind requirements of ASCE 7-95, the stability criteria of applicable
10 53 00 – page 2 building code, and all other governing criteria.
1.06 Quality Assurance
A. Protective Cover shall be wholly produced by a recognized manufacturer with at least five years experience in the design and fabrication of extruded aluminum vehicle cover systems. Components shall be assembled in shop to greatest extent possible to minimize field assembly. Protective cover shall be installed by a manufacturer certified installer. Protective cover system, including material and workmanship, shall be warranted from defects for a period of one year from substantial completion of installation.
PART 2 - PRODUCT
2.01 Manufacturer – Basis for Design
A. Contract documents are based on the basis for design products manufactured by:
1) Peachtree Protective Covers, Inc., 1477 Rosedale Drive, Hiram, GA 30141 770/439-2120, fax 770/439-2122 800/341-3325, ppc@peachtreecovers.com , www.peachtreecovers.com
2) E.L. Burns Company, Shreveport, LA
3) Dittmer Architectural Aluminum, Winter Springs, FL
B. Other manufacturers will be considered for substitution only when the following conditions are met:
1) Other manufacturers must qualify to bid not less than 72 hours prior to bid closing date.
2) Complete details, including sizes of all members and structural calculations showing loads applied in accordance with the specification must be submitted to the architect for review.
2.02 Design
A. Protective cover shall be all welded extruded aluminum system complete with internal drainage. Non-welded systems are not acceptable.
B. Roll formed deck is not acceptable. Expansion joints shall be included to accommodate temperature changes of 120 degrees F. Expansion joints shall have no metal to metal contact.
2.03 Materials
A. Aluminum Members: All sections shall be extruded aluminum 6063 alloy, heat treated to T-6 temper.
D. Fasteners: Fasteners shall be aluminum, 18-8 stainless steel or 300
10 53 00 – page 3 series stainless steel.
E. Protective Coating: Aluminum embedded in or in contract with concrete shall be protected by clear acrylic.
F. Grout: Grout shall be 2000 p.s.i. compressive strength, 1 part Portland cement and 3 parts masonry sand. Add water to produce pouring consistency.
G. Gaskets: Gaskets shall be dry seal santoprene pressure type.
2.04 Components
A. Wall struts/braces: Struts shall be tubular extrusion of minimum size of 2”x2”. All brackets, and fasteners shall be stainless steel or aluminum.
B. Beams: Beams (when required) shall be open-top tubular extrusion, top edges thickened for strength and designed to receive deck members in self-flashing manner. Structural ties shall be installed in tops of all beams.
C. Deck: Deck shall be extruded self-flashing sections interlocking into a composite unit. Closures at deck ends shall be welded plates.
D. Fascia: Fascia shall be manufacturer's standard shape. Size as indicated on drawings.
E. Flashing: Flashing shall be .040 aluminum (min.).
2.05 Fabrication
A. Bent Construction: Beams and columns shall be factory welded with neatly mitered corners into one-piece rigid bents. All welds shall be smooth and uniform using an inert gas shielded arc. Suitable edge preparation shall be performed to assure 100% penetration. Grind welds only where interfering with adjoining structure to allow for flush connection. Field welding is not permitted. Rigid mechanical joints shall be used when shipping limitations prohibit the shipment of fully welded bents.
B. Deck Construction: Deck shall be manufactured of extruded modules that interlock in a self-flashing manner. Interlocking joints shall be positively fastened at 8" O.C. creating a monolithic structural unit capable of developing the full strength of the sections. The fastenings must have minimum shear strength of 350 pounds each. Deck shall be assembled with sufficient camber to offset dead load deflection.
2.06 Factory Finishing
A. Class I Natural Anodized Finish: AAMA 611 AA-M12C22A41 Clear anodic coating or AAMA 612 clear anodic coating with electrolytically deposited organic seal; not less than 0.7 mils (0.018 mm) thick.
B. Color: To be selected by Architect from manufacturer's standard range.
C. Touch-Up Materials: As recommended by coating manufacturer for field application.
PART 3 - EXECUTION
3.01 Preparation
