ii. The first-floor framing aligned in the east-west direction appeared to exhibit a similar bow to the window sills discussed in Item a(i). iii. Warping of interior east-west aligned doorway for the first-floor unit at the building midpoint. iv. Separation of horizontal sheathing ends on the north wall at the building midpoint, approximately 6 to 8 feet above the first floor level. b. The building is generally supported by wood posts measuring approximately 8x8. The following are the observed conditions: i. The building includes three lines of posts in the east-west direction. Post spacing along the lines is approximately 16-20 feet. ii. Post height approximately doubles at the east end relative to the west end due to sloping ground under the building. iii. All posts appeared to bear small,shallow unreinforced concrete pads. No clear separation between the posts and pads was observed, except as noted in the following comments. iv. Multiple posts have been shimmed. It was not clear if the shims were part of the original construction. v. Multiple posts included various forms of blocking(i.e.,supplemental concrete pads, flatwise wood of varying thickness). vi. The posts did not appear to include positive connections (e.g., nails,straps, etc.)to either the first floor framing or the foundations. Load transfer and connectivity are through bearing and friction only, respectively. vii. The posts generally appeared in good condition and without decay. Multiple posts were stabbed with a saw blade, including several with a damped appearance. The blade did not penetrate more than 1/8 inch. viii. Multiple supplemental posts that are not part of the original construction were observed. Most posts were located between the original posts,though one or more of the original posts may have been replaced. Supplemental posts appeared to be provided at locations where the original first floor framing had been cut, replaced, supplemented,or otherwise altered from the original condition. Construction of the supplemental posts and the supporting foundations tended to be consistent with the type and quality of the original construction. c. The lateral stability of the building between the first floor and the ground (i.e.,within the crawl space) is typically provided by wood knee braces only. The following are the observed conditions: i. Braces generally consisted of 2x4 or 2x6 members nailed to either the faces or sides of the floor framing and posts. ii._ Braces are oriented at an.approximate_45-degree_angle. Braces generally do not connect lower than the post mid-height at the east end. iii. Braces are provided at each post and on each side in the east-west direction. iv. Less braces were provided in the north-south direction. Braces were only observed for the first two rows at the east end,one to two rows near the building midpoint, and one or two rows a the building west end. C3(
