PART 3 –
EXECUTION
3.1 EXAMINATION AND PREPARATION
A. General contractor and glazing contractor shall examine all areas, substrates and conditions where glass door assemblies are to be installed. Do not proceed with any work until satisfactory conditions exist for proper installation of all materials.
B. Clean glazing channels and other framing members receiving glass immediately before glazing.
3.2 GLAZING
A. General: Comply with written instructions of manufacturers of glass, sealant, gasket, and other glazing materials, unless more stringent requirements are indicated, including those in referenced glazing publications.
1. Glazing channel dimensions, as indicated on drawings, shall provide necessary bite on glass, minimum edge and face clearance, and adequate sealant thicknesses, with reasonable tolerances.
2. Protect glass edges from damage during handling and installation. Remove damaged glass from project site and legally dispose of off project site. Damaged glass is glass with edge damage or other imperfections that, when installed, could weaken glass and impair performance.
B. Follow industry best practices, published guidelines of the Glass Association of North America, and applicable manufacturer’s recommendations for proper tape, gasket, sealant, and lock-strip glazing.
3.3 PROTECTION AND CLEANING
A. Protect exterior glass from damage immediately after installation by attaching crossed streamers to framing held away from glass. Do not apply markers to glass surface. Remove non-permanent labels, and clean surface.
B. Protect glass from contact with contaminating substances resulting from construction operations, including weld splatter. If, despite such protection, contaminating substances do come in contact with glass, remove them immediately as recommended by the glass manufacturer.
C. Examine glass surface adjacent to or below exterior concrete and other masonry surfaces at frequent intervals during construction, but not less than once a month, for build-up of dirt, scum, alkaline deposits, or stain: remove as recommended by glass manufacturer.
D. Remove and replace glass that is broken, chipped, cracked, abraded, or damaged in any way, including natural causes, accidents, and vandalism, during construction period.
E. Wash glass on both exposed surfaces in each area of project not more than four days before date scheduled for inspections that establish date of substantial completion. Wash glass as recommended by glass manufacturer.
