STRUCTURAL COMMENTS
S1. Please verify that the redundancy factor of 1.0 is applicable to this project. Per ASCE7-10
section 12.3.4.2, for Seismic Design Category D, which this projected is assigned to, the
redundancy factor should be 1.3. Please verify and revise calculations or provide
calculations which demonstrate either of the two applicable exceptions.
S2. Along shearwall line C, 2'-6" length shearwalls are shown in the garage which has a ceiling
height of 10'-4". These shearwalls have a height to length ratio greater than 3.5 which is not
permitted per AWC SDPWS-2015 section 4.3.4.1 and table 4.3.4. Please correct.
S3. Please provide a letter from the Engineer of Record stating that the roof truss calculations
and plans have been fully reviewed and found to be in compliance with the applicable
building codes and requirements specified in the plans.
S4. Please provide foundation calculations showing that the bearing capacity of the soil does
not exceed 1500 psf at any of the spread footings or continuous footings. Please provide
calculations demonstrating that the bearing capacity at the worst case shearwall boundary
element does not exceed the allowable given in CBC table 1806.2
S5. A note on sheet S3 indicates that the girder trusses are to be supported by 2x studs directly
underneath each girder and will have the same number of studs as there are number of

plies in the girder truss. Provide calculations for the larger reaction loads showing the studs
have adequate capacity. Please indicate the size of studs at the interior bearing walls.
Please show how each truss will be supported that has a reaction greater than 2.5 kips. Will
a stud be directly under each of those trusses? Please clarify how each truss will be
supported and provide calculations showing the following:
a. The capacity of a double top plate when a truss is not placed directly over the stud
b. The capacity of the stud to support the trusses
c. The crushing capacity of the top plate when the load is perpendicular to the grain
d. The crushing capacity of the sill plate when the load is perpendicular to the grain
and the incising factor from AWC NDS -2015 section 4.3.8 is used for pressure
treated wood.
e. The bearing capacity of the foundation including spread footings that support a
beam which supports an interior bearing wall.
Along each shear wall, the assumption has been made that all lateral loads are equally
distributed to each of the shear wall segments. The basis of this assumption is founded on
premise that there is continuity in the roof diaphragm. As such, provide justification and/or
verification that there are adequate collectors, straps or ties between the shear walls. Drag
trusses and truss blocking could not be located on the plans at the shearwalls. Please
show how the load is transferred from the roof sheathing to each shearwall. ASCE 7-10,
Sec. 12.10.2
Please provide a detail showing the connection of the roof truss over a non-bearing wall
that is both parallel and perpendicular to the truss. Ensure to indicate a gap between the
wall and the truss and provide a fastener that is for a positive connection.
Please provide a detail showing a typical hold down installation at the foundation.
Provide a detail showing the grade beam at the garage door entrance as called out on
sheet S1.
