Devices, apparatus, systems and methods of installing one-piece sleeve assemblies corrugated decks in floors that are used for plumbing, mechanical, electrical and miscellaneous pipe applications, against water, fire and smoke. A one-piece sleeve assembly combines a resilient sealing member with perimeter extending side walls extending from a central opening that gets poured in place during the concrete pour on the corrugated deck that forms a water, fire and smoke sealed opening about the resilient sealing member and also allows for expansion and contraction of the concrete that surrounds the resilient member, a deck base having outwardly extending wings about a central opening that is aligned with the central opening of the resilient member, and clipped fire stop material that encircles a portion of the central opening of the deck base. The one piece sleeve assembly is installed in a cut out opening the corrugated deck floor so that concrete can then be poured onto the deck about the one-piece assembly. A pipe positioned through the one piece sleeve assembly is sealed in place, by that positioning, so that an outer perimeter of the pipe is sealed against allowing water, smoke and fire to pass around the pipe through the floor and allowing for expansion and contraction of the pipe that passes through the device, and fire and smoke is further prevented from passing about the outer perimeter by the fire stop material which expands from heat.
