3 EXECUTION
3.1 Pipe Escutcheons: Install pipe escutcheons on each pipe penetration through floors, walls,
partitions, and ceilings where penetration is exposed to view; and on exterior of building.
Secure escutcheon to pipe or insulation so escutcheon covers penetration hole, and is flush
with adjoining surface.
3.2 Fire Barrier Penetration Seals: Provide pipe sleeve as required. Refer to Division 7.
3.3 Pipe Sleeves: Install pipe sleeves of types indicated where piping passes through walls,
floors, ceilings, and roofs. Do not install sleeves through structural members of work, except
as detailed on drawings, or as reviewed by Architect/Engineer. Install sleeves accurately
centered on pipe runs. Size sleeves so that piping and insulation (if any) will have free
movement in sleeve, including allowance for thermal expansion; but not less than 2 pipe sizes
larger than piping run. Where insulation includes vapor-barrier jacket, provide sleeve with
sufficient clearance for installation. Install length of sleeve equal to thickness of construction
penetrated, and finish flush to surface; except floor sleeves. Extend floor sleeves ¼" above
level floor finish, and ¾" above floor finish sloped to drain. Provide temporary support of
