Most engineering judgments are a result of inadequate planning relating
to the configuration of penetrations in fire-related construction
In the new construction market, the need for an engineering judgment
in place of a UL-classified firestop system should be a very limited
occurrence. Proper upfront planning and coordination of trades
is a necessary component to a quality firestop installation process.
However, situations do occur where configurations of penetrating
items fall outside the parameters of existing systems. Review the industry-recommended guidelines for evaluating engineering
The question is often asked: Is an engineering judgment code
The provisions of the international building code are not to prevent
the installation of any material or to prohibit any design method
not specifically prescribed. An alternative material, design or
method of construction shall be approved where the building official
finds that the proposed design is satisfactory and complies with
the intent of the code. This is known as an alternative method
and an engineering judgment may be found to be acceptable to the
building official as acceptable. Review 104.11 Alternative

Disclaimer: Engineering judgments should not be used in lieu of
tested systems when available, and should be issued only by a
firestop manufacturers qualified technical personnel or
in concert with the manufacturer, by a registered Professional
Engineer or independent testing agency that provides listing services
