<br /> IBC 2012 STRUCTURAL NOTES F(CONTINUED)
<br /> Framing contractors written company safety program must be submitted prior
<br /> To commencing work
<br /> All gravity load resisting and lateral load resisting structural members are shown Subcontractor shall work with superintendent to crrect and complete
<br /> on the engineering structural pages. The enclosed engineering calculations document the Lumber package 24 hr. must be given to the job superintendent to replace
<br /> analysis used to determine the structural members of the structural pages. The Missing material or to add material to the lumber list.
<br /> engineering calculations are not required to be referenced for construction.
<br /> Excess material that can not be use for blocking, shimming, etc. and other
<br /> Contractor shall verify all notes, dimensions and conditions prior to construction.
<br /> Contractor shall provide temporary bracing as required until all permanent connections Debris as may be created by the work, shall be placed designated areas.

<br /> discrepancies at the time they are noted.
<br /> (IBC 2301.2) There are three methods for the design of wood based structural 4x, 6x, beams and posts: DF #1, Fv=95 PSI, Fb=1,200 PSI

<br /> Investigation is provided foundation design is based on an assumed average soil bearing
<br /> Of 1500 PSF. Organic silt, organic clays, peat or unprepared fill shall not be assumed to Fasteners for pressure treated and fire retardant treated wood shall be of
<br /> Have a bearing capacity unless dare are submitted (1806). Hot—dipped galvanized steel, stainless steel, silicon bronze or copper.
