49930 N Santiam Hwy SE SITE VISIT REPORT <br /> Idanha, OR 97350-9503 State Farm Claim No. 37-11 K4-75P <br /> 2. GARAGE - MEZZANINE FLOOR JOISTS <br /> As discussed above, under EXISTING BUILDINGS, the mezzanine floor consists <br /> of plywood sheathing over 2x10 wood joists @ 16" on-center spacing. Grade stamps <br /> were on the framing, indicating 3/4" nominal plywood (0.719" min.) 48/24 span <br /> rating, and Douglas-Fir No. 2 joists. <br /> The Policyholder indicated concern with the West mezzanine floor joists, which <br /> are below the playroom, where there appeared to be soot on some of the joists. He <br /> pointed out a joist that the Hygienist had taken a sample from. The scope of this <br /> report does not include hygiene, toxins, chemicals, or similar health hazards - those <br /> issues are being addressed by others. The scope of this report concerns the structural <br /> safety of the building and its components with respect to heat from the wildfire. <br /> Upon observation, soot that may be on the wood is not detrimental to the <br /> strength or structural safety of the joists for support of loads. It was possible to <br /> scrape the very thin layer off with a fingernail. The soot may be removed through <br /> sanding or similar means, or encapsulated, it ---- ' <br /> the Hygienist or others. [See Figures 26 & 2' <br /> prctool( 9015 116 <br /> 44 104) (f" <br /> LOW " e ti)6 <br /> .15 <br /> WEST MEZZANINE, AND SOOT OP <br /> The Policyholder also pointed out cracking in one of the 2x10 floor joists. It <br /> consists of discontinuous cracks (or "checks") near the centroid of the depth of the <br /> joist on one side only, along the full length of the joist. These cracks are due to <br /> where the 2x10 was cut from within the log, with differential shrinkage amongst the <br /> growth rings as the moisture content decreased. This is not uncommon and is not a <br /> structural concern. [See Figure 28 below.] <br /> I told the Policyholder that I would analyze the mezzanine floor joists for him, <br /> so that he would have a sense of their collective capacity or safety.
