          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.Examine metal panel system substrate with Installer present. Inspect for erection tolerances and other conditions that would adversely affect installation of metal panels.
          1.Inspect framing that will support insulated metal panels to determine if support components are installed as indicated on approved shop drawings and are within tolerances acceptable to metal panel manufacturer and installer. Confirm presence of acceptable framing members at recommended spacing to match installation requirements of metal panels.
          2.Panel Support Tolerances: Confirm that metal panel supports are within tolerances acceptable to metal panel manufacturer but not greater than the following:
          a.Maximum 1/4 inch (6 mm) in 20 foot (6100 mm) in any direction.
          b.Maximum 3/8 inch (9 mm) over any single wall plane.
          c.Girt Spacing of 8 feet (2438 mm) or More: 1/4 inch (6 mm) out only.
          d.Girt Spacing of Less Than 8 feet (2438 mm): 1/8 inch (3 mm) out only.
          e.CF Architectural Girt Spacing Less Than 4 feet (1219 mm): 1/16 inch (1.5 mm) out only.
 
          B.Correct out-of-tolerance work and other deficient conditions prior to proceeding with insulated metal panel installation.
 
          3.2INSTALLATION
 
          A.Install metal panel system in accordance with manufacturer's written instructions, approved shop drawings, and project drawings. Install metal panels in orientation, sizes, and locations indicated. Anchor panels and other components securely in place. Provide for thermal and structural movement.
 
          B.Attach panels to metal framing using screws, fasteners, sealants, and adhesives recommended for application by metal panel manufacturer.
          1.Fasten metal panels to supports with fasteners at each location indicated on approved shop drawings, at spacing and with fasteners recommended by manufacturer.
          2.Cut panels in field where required using manufacturer's recommended methods.
          3.Provide weatherproof jacks for pipe and conduit penetrating metal panels.
          4.Dissimilar Materials: Where elements of metal panel system will come into contact with dissimilar materials, treat faces and edges in contact with dissimilar materials as recommended by metal panel manufacturer.
 
          C.Attach panel flashing trim pieces to supports using recommended fasteners and joint sealers.
 
          D.Joint Sealers: Install sealants where indicated and where required for weatherproof performance of metal panel assemblies.
          1.Seal panel base assembly, openings, panel head joints, and perimeter joints using sealants indicated in manufacturer's instructions.
          ** NOTE TO SPECIFIER ** Delete if not required.
          2.Seal wall panel joints; apply continuously without gaps in accordance with manufacturer's written instructions, approved shop drawings, and project drawings.
          3.Prepare joints and apply sealants per requirements of Division 07 Section.
 
          E.Accessories: Install metal panel accessories with positive anchorage to building and weather tight mounting; provide for thermal expansion. Coordinate installation with flashings and other components.
          1.Install components required for a complete metal panel assembly, including trim, copings, flashings, sealants, closure strips, and similar items.
          2.Comply with details of assemblies utilized to establish compliance with performance requirements and manufacturer's written installation instructions.
          3.Set units true to line and level as indicated. Install work with laps, joints, and seams that will be permanently weather resistant.
 
          3.3FIELD QUALITY CONTROL
          ** NOTE TO SPECIFIER ** Delete quality control options not required.
 
          A.Testing Agency: Owner will engage an independent testing and inspecting agency acceptable to Architect to perform field tests and inspections and to prepare test reports.
 
          B.Testing Agency: Engage an independent testing and inspecting agency acceptable to Architect to perform field tests and inspections and to prepare test reports.
 
          C.Water-Spray Test: After completing portion of metal panel assembly including accessories and trim, test 2-bay area selected by Architect for water penetration, according to AAMA 501.2.
 
          3.4CLEANING
 
          A.Remove temporary protective films immediately in accordance with metal panel manufacturer's instructions. Clean finished surfaces as recommended by metal panel manufacturer.
 
          3.5PROTECTION
 
          A.Protect installed products until completion of project.
 
          B.Replace damaged panels and accessories that cannot be repaired to the satisfaction of the Architect.
