RE: Plan Check: BLD2015-1258
Project: Maston SFR
nd
Project Address: 21819 92 Avenue W
During a review of the plans by the Building Division for the above noted project, it was found that
. A complete review cannot be
the following information, clarifications, or changes are needed
performed until the revised plans/documents, including a written response indicating where
the clouded or otherwise highlighted changes can be found on the revised plans, have been
submitted to a Permit Coordinator.
nd
Resubmittals must be made at the Development Services Department on the 2 Floor of City
Hall. Permit Center hours are M, T, Th, & F from 8am-4:30pm. The Permit Center is closed
on Wednesdays.
Reviews by other divisions, such as Planning, Engineering, or Fire, may result in additional
comments.
On the Residential Building Permit Application Form A:
1.Mechanical/Fuel Gas Clarify the difference in the proposed method of providing comfort
heat and that required per the selected Washington State Energy Code (WSEC) Table
R406.2 option 3a indicated on sheet A1 and the submitted WSEC Prescriptive Energy
Code Compliance for All Climates in Washington form. The building permit drawings
shall specify the option being selected and shall specify the heating equipment type and the
minimum equipment efficiency of the desired method per WSEC Table 406.2.
On sheet A3:
2.Foundation Plan
a.Provide on the plans a callout for Detail 3 on sheet G1 for the continuous
footings/foundations to guide proper review, construction, and inspection.
b.Indicate on the plans the minimum required widened footing to support the loads
below the converging ends of the girder truss over the Guest Room and beam GB-
1 5-1/8x15 GLB. The typical footing appears to be undersized for the loads
anticipated by the represented construction.
c.Clarify the callout for the 36x36x8 widened footing to support the loads below the
converging ends of beam GB-1 5-1/8x15 GLB - and beam GB-2 5-1/8x24
GLB (identified on the plans as GB-1 also). It appears to be undersized for the
loads noted in the provided structural calculations.
3.Holdown Schedule Indicate on the plans the required anchorage for holdown T-5
HD5B to resist the overturning loads noted in the provided structural calculations.
On sheet A4:
4.Main Floor Plan
a.Clarify the difference in the T-3 holdowns MSTA36 - specified at each end of the
P1-6 shear walls along wall line A and of that called out at those locations on
sheet A3. The elevations/anticipated construction do not appear to facilitate the
proposed installation- see also the review note below.
b.Clarify the callout for the T-3 MSTA36 straps to be used to transfer the
overturning loads through the floor diaphragm at each end of the P1-6 shear walls
along wall line A north walls of the Pantry, Kitchen, Dining Room, and the
Great Room. Due to the 12 inch deep floor joists, the effective lengths at each end
of the straps and number of nails within them do not appear capable of achieving the
loads indicated in the provided calculations see also the review note above.
c.Indicate on the plans the minimum required beam to support the loads over the
window in the north wall of the Dining Room. The typical 4x10 DF #2 appears
to be over spanned and fails in bending.
d.Provide on the plans a detail, and a reference to it, for the required construction to
transfer the lateral loads from the upper floor diaphragm to the P1-2 shear walls
along the south wall of the Guest Room/wall line C.
On sheet A5:
5.Upper Floor Plan
a.Clarify on the plans the difference in the indicated location of the proposed furnace
and of that noted for the proposed air handler and heat pump on the City of Edmonds
Residential Building Permit Application Form A see also review comment 1.
b.Clarify the callout for the T-3 MSTA36 straps to be used to transfer the
overturning loads through the floor diaphragm at each end of the P1-6 shear walls
along wall line 2 west walls of the Master Bedroom and the Bonus Room.
Due to the 18 inch deep floor trusses, the effective lengths at each end of the straps
and number of nails within them do not appear capable of achieving the loads
indicated in the provided calculations. A longer strap at the south end of the north-
most shear wall and at each end of the south-most shear wall may require a strap
intended for connection to a beam below.
c.Clarify the callout for the T-3 MSTA36 straps to be used to transfer the
overturning loads through the floor diaphragm at each end of the P1-6 shear walls
along wall line B south walls of the Laundry and Bedroom Three. Due to the
18 inch deep floor trusses, the effective lengths at each end of the straps and number
of nails within them do not appear capable of achieving the loads indicated in the
provided calculations. A longer strap at the west end of the west-most shear wall
may require a strap intended for connection to a beam below.
