| Description |
This drawing is intended to illustrate common guidelines for the forming of through-penetrations such that proper sizing and costing for firestops can occur. In the case of sleeving, which is limited to fire-separations made of concrete and masonry, the mechanical and electrical trades are responsible for the sizing of the openings because they apply the sleeves. In the case of drywall fire separations, the opening size is determined by the drywall contractor, unless the mechanical and electrical trades are contractually obliged to provide sleeving here as well, with proper fastening methods that must be subject to bounding. All trades shall can use this guideline. This permits accurate priceing as well as accountability for field variances. Exceptions are penetrations in timber floors. Often, timber floor openings are simply cut by means of a chainsaw. In this case, the width of the blade will determine sizes. Sizing of all openings has significant impact upon bounding. Therefore, communication between all affected trades is of great importance before any openings are made. |
