Memo to McCanaoa Tatum Residence Inspection page 3 Exterior Structural Examination The exterior walls of the structure also exhibit generally pervasive cracking. The majority of these vertical cracks, however, are hairline and do not open appreciably in either direction. The south and east walls of the two story section of the building are the exception. These walla; particularly near the southeastern corner, exhibit open cracking, wider toward the upper story ceiling level. Buttresses, which appear to be hollow architectural cosmetic treatments, are attached to the southeast and northeast corners of the structure. These both exhibit separation cracks, opening upward, terminating with cracks angling at approximately 45 degrees up and away from the vertical wall plane. The buttresses appear to be rotating away from the structure at their upper ends. Disintegration of the exterior stucco covering makes these cracks appear larger than the actual separation offset. A concrete slab approximately 16 feet by 25 feet is located at the entrance to the garage. This slab exhibits some normal shrinkage cracking and loading cracks at the outer apron corners. However, no offsets exist across any of the cracks. The same is true of the concrete slab walk from the front gate to the terrace outside the kitchen. The flagstone covered terrace floor between the garage and the kitchen exhibits some cracking, and the mortar between the flagstone has disaggregated in a few places. But the slab and flagstone do not exhibit offsets across any of the cracks. Crawl Space Examination I entered the crawl space beneath the main floor from the partial basement. The remainder of our party declined to accompany me. Joe Dudash seared as spotter for me. I examined the crawl space foundation walls by flashlight and. took flash photos. The foundation consists of field rock and mortar walls founded in excavated trenchs. Two to three courses of unfinished adobe blocks are placed on top of the field stone wall as a leveling course. Finally, wooden blocks support the floor joists. The crawl space is excavated as much as 2 1/2 feet into shale bedrock. This upper shale is dry but intact. In the bottom of the crawl space, at a distance of over fifteen feet from the partial basement interior east wall, the shale appears moist but not wet to the touch. No cracking or disaggregation of the grout was observed at any location in the field rock walls or the adobe leveling course. While props and shims had been installed at several locations beneath the joists, presumably for squeak prevention, no movement appeared evident at any of these supported locations. None of these shimmed supports had been unloaded or dislodged.
