The estimator can, however, expect complete construction drawing information for fire undergrounds, fire hydrants, and required FDCs. Specifications should indicate the required sprinkler spacing and type of sprinkler heads but not necessarily the completed design drawings for the interior system. The construction estimator should fully review all of the plans and specifications and perform a site walk. Due to the construction drawings being incomplete regarding the interior system, any introduction to fire sprinklers and fire suppression systems requires exposure to NFPA codes.
Stookey, You are starting to frighten me. I think, actually assuming, all building codes require some sort of rating between a combustible attic space and the area below. We have a single story hotel that has a combustible attic. If this is so it doesn't happen anywhere I am aware of. For the first time I really want you to tell me I am wrong. Its just a ceiling. Two layers may have been applied because of energy code implications or the architect was trying to reduce the sound transmission level.
From a consistency standpoint can we put in specific requirements for sealing sprinkler heads when we haven't really done this for other penetrations? The air seal should be between the pipe and the air barrier, not between the sprinkler head itself and the air barrier. I hope they respond.
Summary[ edit ] Sprinkler branch pipe through-penetration with plasticsleeve - missing firestop in concrete fire separation. The branch pipe is a penetrant , as is the plastic sleeve, which is a code violation if left in place, unless subject to bounding with a firestop that permits such sleeving to be left in place.
