SLEEVE INSTALLATION FOR COMMUNICATIONS PENETRATIONS A. Communications penetrations occur when pathways, cables, wireways, or cable trays penetrate concrete slabs, concrete or masonry walls, or other wall assemblies. B. Concrete Slabs and All Walls: Install sleeves for penetrations unless core-drilled holes or formed openings are used. Install sleeves during erection of slabs and walls. C. Use pipe sleeves unless penetration arrangement requires rectangular sleeved opening. D. Fire-Rated Assemblies: Install sleeves for penetrations of fire-rated floor and wall assemblies unless openings compatible with firestop system used are fabricated during construction of floor or wall. E. Cut sleeves to length for mounting flush with both surfaces of walls. F. Extend sleeves installed in floors 2 inches above finished floor level. G. Size pipe sleeves to provide 1/4-inch annular clear space between sleeve and pathway or cable, unless indicated otherwise. H. Seal space outside of sleeves with grout for penetrations of concrete and masonry 1. Promptly pack grout solidly between sleeve and wall so no voids remain. Tool exposed surfaces smooth; protect grout while curing. I. Interior Penetrations of Non-Fire-Rated Walls and Floors: Seal annular space between sleeve and pathway or cable, using joint sealant appropriate for size, depth, and location of joint. Comply with requirements in Division 07 Section "Joint Sealants.". J.
