PASSMORE CENTER ADDITION AND RENOVATION <br />HILLSBOROUGH, NORTH CAROLINA <br />SECTION 105305 — ALUMINUM WALKWAY CANOPY (Addendum #1) <br />PART 1 - GENERAL <br />1.1 RELATED DOCUMENTS <br />A. Drawings and general provisions of the Contract, including General and Supplementary <br />Conditions and Division 1 Specification Sections, apply to this Section. <br />1.2 SUMMARY <br />A. Section Includes: Design, fabrication, and installation of welded extruded aluminum walkway <br />cover systems. <br />B. Related Sections include the following: <br />1. Division 2 Section "Cement Concrete Paving" for concrete walkways. <br />2. Division 3 Section "Cast -in -Place Concrete" for reinforcing of slab at canopy footings. <br />C. Products Furnished but not Installed Under this Section: <br />1. Column sleeves. <br />2. Anchor bolts. <br />1.3 PERFORMANCE REQUIREMENTS <br />A. Structural Performance: Provide a pre- engineered metal canopy capable of withstanding the <br />effects of gravity loads and the following loads and stresses within limits and under conditions <br />indicated: <br />1. Wind Loads: Determine loads based on the following minimum design wind pressures: <br />a. Uniform pressure as indicated on Drawings. <br />2. Snow Loads: 15 lbf/sq. ft. (104 kN /sq. m). <br />B. Seismic Performance: Provide pre - engineered metal canopy capable of withstanding the <br />effects of earthquake motions determined according to ASCE 7, "Minimum Design Loads for <br />Buildings and Other Structures ": Section 9, "Earthquake Loads." <br />C. Thermal Movements: Provide pre- engineered metal canopy that allows for thermal movements <br />resulting from the following maximum change (range) in ambient and surface temperatures by <br />preventing buckling, opening of joints, overstressing of components, failure of joint sealants, <br />failure of connections, and other detrimental effects. Base engineering calculation on surface <br />temperatures of materials due to both solar heat gain and nighttime -sky heat loss. <br />ALUMINUM WALKWAY CANOPY (Addendum #1) 105305-1 <br />
