When calculating hole locations by this optional method, the following minimum distances between the center of the hole and the inside face of the support apply.

NOTES
1. Above tables may be used for P3 Joist spacing of 24” on center or less.
2. Hole location distance is measured from inside face of supports to center of hole.
3. Distances in this chart are based on uniformly loaded joists.
4. Hole sizes and/or locations that fall outside of the scope of this table may be acceptable based
on analysis of actual hole size, span, spacing, and loading conditions.
5. SAF stands for Span Adjustment Factor. SAF is used as defined below.
OPTIONAL
Table 4 is based on the P3 Joists being used at their maximum span. If the P3Joists are placed
at less than their full allowable span, the maximum distance from thecenterline of the hole to the
face of any support (D) as given above may be reduced as follows.
D
reduced
= L
actual
x D
SAF
Where: D
reduced
= Distance from the inside face of any support to center of hole is reduced for less-
than-maximum span applications (ft). The reduced distance shall not be less than
6” from the face of support to edge of the hole.
L
actual
= The actual measured span distance between the inside faces of supports (ft)
SAF = Span Adjustment Factor is given in the table above.
D = The minimum distance from the inside face of any support to center of hole from
Table 4 above
If L
actual
is greater than 1, use 1 in the above calculation for L
actual
.
