PARCEL # 55063,0133
Dear Glenn:
Spokane Structures sold this post frame building to Mr. Johnson for erection in Spokane Valley, WA using standard
post frame building plans I have prepared for Spokane Structures. The building is designed for 30 PSF roof live
(snow) load. 85 MPH wind speed, Exposure 8, Seismic Design Category C, 2,000 PSF allowable soil bearing
pressure and IBC 2006. The building has 10' post spacing and 4:12 roof trusses.
I have reviewed the design of this building and checked h for the diaphragm design requirements used in
development of the standard plans. The front endwall has two 4'0" x 3'0' windows located beneath the upper plate
plus a 3' pass door and another 4' x 3' window in one comer. There is sufficient sheeting on this endwall to provide
adequate lateral bracing for this endwall of the building against lateral loads on the roof and sidewalls.
The rear endwall has two 4'0" x 3'0" windows located beneath the upper plate. There is sufficient sheeting on this
endwall to transfer lateral loads on the sidewall and roof to the base of the building.
The left sidewall has no openings. The right sidewall has two 12'x 14' overhead doors with roof trusses supported by
glue lam beams. sidewall openings have no effect on the lateral load resistance of this building.
You may use the standard post frame building plans to erect this building with details for the glue lam beams.
Please feel free to. contact me if you have any additional questions about the design of this building.
