the following information, clarifications, or changes are needed. A complete review cannot be
performed until the revised plans/documents, including a written response indicating where the

result in additional comments.

2.Guardrail Attachment Soffit and Insulation Detail Clarify the reference to the FHA 1/300
rule regarding the required roof ventilation. The applicable code requires a net free
ventilation area of 1/150 of the area of the vented space per IRC R806.2. Indicate on the
plans the minimum number of, or length of, the specified soffit vents to be installed to meet
this requirement.
3.Plan Indicate on the plans the minimum required beams to support the loads over the
following openings:
a.The two windows immediately below the proposed roof deck on the north side of the
structure.
b.The small window immediately below the proposed roof deck on the south side of
the structure.
c.The sliding glass door immediately below the proposed roof deck on the south side
of the structure.
The installation of the full-span trusses appears to double the loads over the existing
openings.
