KAISER PERMANENTE Site Prep #1 Electrical Service <br />ASC & Clinic (HUB) March 18, 2020 <br />Everett, WA Project No. 19.05002.00 <br />C. Coordination Drawings: <br />Comply with requirements in Section 01 33 00 and Section 23 05 00 for providing <br />coordination drawings for areas as indicated on the drawings. Approved <br />ductwork shop drawings shall be used to generate coordination drawings. <br />D. Reports and Certificates: Provide submittals of the following: <br />1. Duct Leakage Test Report. <br />2. Duct Cleanliness Tests. <br />3. Welding certificates. <br />E. Welding and finish sample for exposed stainless steel and aluminum ducts. <br />1.5 QUALITY ASSURANCE <br />A. Fabricate ducts and fittings according to SMACNA "HVAC Duct Construction Standards -- <br />Metal and Flexible" unless otherwise indicated. <br />B. Welding Standards: Qualify welding procedures and welding personnel to perform <br />welding processes for this Project according to AWS D1.1, "Structural Welding Code -- <br />Steel," for hangers and supports; AWS D1.2, "Structural Welding Code --Aluminum," for <br />aluminum supporting members, AWS D9.1; and "Sheet Metal Welding Code," for duct <br />joint and seam welding. <br />C. Comply with NFPA 90A, "Installation of Air Conditioning and Ventilating Systems" unless <br />otherwise indicated. <br />1.6 DELIVERY, STORAGE, AND HANDLING <br />A. Keep metal ducts and duct liner dry and dust free during fabrication and storage at <br />factory. <br />B. Before shipment shrink-wrap all openings of ducts fabricated with duct liner. During <br />shipment, protect all metal ducts from weather. <br />C. Store all metal ducts in dry location on -site on elevated dunnage. Protect metal ducts <br />from moisture, dirt, and dust. <br />D. Retain shrink-wrap protection of openings (where required to be protected) until <br />immediately prior to connection of that opening to erected duct system. <br />E. On the event that any duct liner does get wet, dry duct liner within 48-hours using forced <br />air heater. Ducts detected with moist fiberglass liner will be required to be replaced at no <br />additional cost to the Owner. <br />F. Remove dust from the inside of metal duct sections as they are erected. Cover all <br />openings with 6-mil poly and duct tape, shrink wrap, or high -tack adhesive film at the end <br />of each workday to prevent dust migration into ducts. <br />G. Deliver and store stainless -steel sheets with mill -applied adhesive protective paper <br />maintained through fabrication and installation. <br />PART 2-PRODUCTS <br />2.1 SHEET METAL MATERIALS <br />A. Galvanized, Sheet Steel: Lock -forming quality; ASTM A 653/A 653M, G90 coating <br />designation; mill-phosphatized finish for surfaces of ducts exposed to view. <br />METAL DUCTS 2331 13 - 2 <br />
