PART 3 - EXECUTION 3

EXAMINATION 5

Examine framing glazing, with Installer present, for compliance with the following: 6 Manufacturing and installation tolerances, including those for size, squareness, and offsets at corners. 7 Presence and functioning of weep system. 8 Minimum required face or edge clearances. 9 Effective sealing between joints of glass-framing members. 10 Proceed with installation only after unsatisfactory conditions have been corrected. 11

PREPARATION 13

Clean glazing channels and other framing members receiving glass immediately before glazing. Remove 14 coatings not firmly bonded to substrates. 15

GLAZING, GENERAL 17

Comply with combined written instructions of manufacturers of glass, sealants, gaskets, and other glazing 18 materials, unless more stringent requirements are indicated, including those in referenced glazing 19 publications. 20 Glazing channel dimensions, as indicated on Drawings, provide necessary bite on glass, minimum edge and 21 face clearances, and adequate sealant thicknesses, with reasonable tolerances. Adjust as required by Project 22 conditions during installation. 23 Protect glass edges from damage during handling and installation. Remove damaged glass from Project site 24 and legally dispose of off Project site. Damaged glass is glass with edge damage or other imperfections that, 25 when installed, could weaken glass and impair performance and appearance. 26 Install setting blocks in sill rabbets, sized and located to comply with referenced glazing publications, unless 27 otherwise required by glass manufacturer. Set blocks in thin course of compatible sealant suitable for heel 28 bead. 29 Do not exceed edge pressures stipulated by glass manufacturers for installing glass lites. 30 Provide spacers for glass lites where length plus width is larger than 50 inches (1270 mm) as follows: 31 Locate spacers directly opposite each other on both inside and outside faces of glass. Install correct size and 32 spacing to preserve required face clearances, unless gaskets and glazing tapes are used that have demonstrated 33 ability to maintain required face clearances and to comply with system performance requirements. 34 Provide 1/8-inch (3-mm) minimum bite of spacers on glass and use thickness equal to sealant width. With 35 glazing tape, use thickness slightly less than final compressed thickness of tape. 36 Provide edge blocking where indicated or needed to prevent glass lites from moving sideways in glazing 37 channel, as recommended in writing by glass manufacturer and according to requirements in referenced 38 glazing publications. 39 Set glass lites in each series with uniform pattern, draw, bow, and similar characteristics. 40 Where wedge-shaped gaskets are driven into one side of channel to pressurize sealant or gasket on opposite 41 side, provide adequate anchorage so gasket cannot walk out when installation is subjected to movement. 42 Square cut wedge-shaped gaskets at corners and install gaskets in a manner recommended by gasket 43 manufacturer to prevent corners from pulling away; seal corner joints and butt joints with sealant 44 recommended by gasket manufacturer. 45

GASKET GLAZING (DRY) 47

Fabricate compression gaskets in lengths recommended by gasket manufacturer to fit openings exactly, with 48 allowance for stretch during installation. 49 Center glass lites in openings on setting blocks and press firmly against soft compression gasket by inserting 50 dense compression gaskets formed and installed to lock in place against faces of removable stops. 51 Start gasket applications at corners and work toward centers of openings. Compress gaskets to produce a 52 weathertight seal without developing bending stresses in glass. Seal gasket joints with sealant recommended 53 by gasket manufacturer. 54 Install gaskets so they protrude past face of glazing stops. 55

08 80 00 - 6

CLEANING AND PROTECTION 1

Protect exterior glass from damage immediately after installation by attaching crossed streamers to framing 2 held away from glass. Do not apply markers to glass surface. Remove nonpermanent labels, and clean 3 surfaces. 4 Protect glass from contact with contaminating substances resulting from construction operations, including 5 weld splatter. If, despite such protection, contaminating substances do come into contact with glass, remove 6 substances immediately as recommended by glass manufacturer. 7 Examine glass surfaces adjacent to or below exterior concrete and other masonry surfaces at frequent 8 intervals during construction, but not less than once a month, for buildup of dirt, scum, alkaline deposits, or 9 stains; remove as recommended in writing by glass manufacturer. 10 Remove and replace glass that is broken, chipped, cracked, or abraded or that is damaged from natural causes, 11 accidents, and vandalism, during construction period. 12 Wash glass on both exposed surfaces in each area of Project not more than four days before date scheduled 13 for inspections that establish date of Substantial Completion. Wash glass as recommended in writing by 14 glass manufacturer. 15
