ENGINEERING
JUDGMENT
PROCESS
Hilti has performed extensive testing
in both through-penetration and
construction joint applications.
However, due to variations in
construction throughout the phases of
a project, it is not possible to test every
application that may be encountered.
For these situations, Hilti has
developed a process for creating
custom drawings to accommodate
particular applications. Hilti custom
drawings, or Engineering Judgments,
are developed through the careful and
restricted application of accepted fire

protection engineering principles and
guidelines set forth by the IFC. Test
data of like systems are analyzed and
applied toward similar applications that
do not exactly meet the criteria of a
current UL Listed System.
If the systems listed in this guide do not
accommodate a particular application,
please photocopy, complete, and
submit the appropriate form(s) to
request an Engineering Judgment on
the following page. Once received, the
requested information will be evaluated
and an Engineering Judgment will be
created, if possible.
Completed form(s) can be emailed to
[email protected].
