Section 107.2.1 states that the construction documents are required
to be of such quality and detail such that the building official can
determine whether the proposed work conforms to the code’s
requirements.
Note: NBC 2016 currently does not include installation and inspection
requirements of Firestop in particular. However, in Chapter 4,
Annexure E, it gives the requirement for Life Safety Audit once in
two years.
Some designers elect to include (or some jurisdictions may require)
a penetration firestop system schedule similar to what would be
provided for a wall, door or window schedule. They select Systems
that are Project Specific :
■ ■
■ ■
■ ■
■ ■
What is the rating required?
What is penetrating floor or wall?
What is a floor or wall made of?
What is the Annular Space?
For example, the planned schedule could indicate something as
simple as “Hilti system ABC is to be used for gypsum-covered metal-
framed walls with pipe penetrations having an annular space of less
than 1 inch, while Hilti system XYZ is to be used if the annular space
exceeds 2 inches.” Specifying the annular space minimums and
maximums from those firestop systems can also serve to ensure
that tradespeople installing those penetrations will not make holes
in the assemblies that are then difficult or costly to protect, or that
would have no available systems and would require an engineering
judgment. Most situations requiring an engineering judgment are
those where the hole shape and size were created without the
eventual firestopping in mind.
