SMACNA – Guideline on through-penetration firestopping

This paper was prepared in response to increasing concerns and lack of understanding of this issue by designers, code officials and contractors. The requirements of the Model Code groups have been identified and the responsibilities of architects, engineers/designers, code officials and contractors have been outlined. The use of this paper will assist contractors in those situations where they are being forced to provide products, which are not adequately specified and detailed on the project plans and specifications and, which were not included in contractors’ estimates for the project. This guideline is intended to be a generic educational tool for use by all parties to the construction process. We encourage all members to provide copies of this paper to building owners, architects, engineers and code officials so that all parties gain an understanding as to the requirements of the codes, their respective responsibilities and the technical complexity and costs associated with this issue.
