Vol 2 - Garney Construction

C. Wind Uplift Pressure: Determine by the IBC for the criteria given on theStructural Drawings.D. Thermal Movements:1. Provide sheet metal flashing and trim that allows for thermalmovements resulting from the following maximum change (range) inambient and surface temperatures by preventing buckling, opening ofjoints, hole elongation, overstressing of components, failure of jointsealants, failure of connections, and other detrimental effects.2. Provide clips that resist rotation and avoid shear stress as a result ofsheet metal and trim thermal movements.3. Base engineering calculation on surface temperatures of materials due toboth solar heat gain and nighttime-sky heat loss.4. Temperature Change (Range): 120 degrees F, ambient; 180 degrees F,material surfaces.E. Water Infiltration: Provide sheet metal flashing and trim that does not allowwater infiltration to building interior.1.03 QUALITY ASSURANCEA. Sheet Metal Flashing and Trim Standard: Comply with SMACNA’s“Architectural Sheet Metal Manual.” Conform to dimensions and profilesshown, unless more stringent requirements are indicated.1.04 SUBMITTALS1. Provide profiles to match existing roof edge and parapet coping, unlessnoted otherwise.A. Action Submittals:1. Shop Drawings:a. Show joints, types and location of fasteners, and special shapes.b. Catalog data for stock manufactured items.2. Samples: Color Samples for items to be factory finished.1.05 DELIVERY, HANDLING, AND STORAGEA. Inspect for damage, dampness, and wet storage stains upon delivery to WorkSite.B. Remove and replace damaged or permanently stained materials that cannot berestored to like-new condition.SHEET METAL FLASHING AND TRIMPW/WBG/38205907 62 00 - 2 AUGUST 15, 2012©COPYRIGHT 2012 CH2M HILL
