Memo to Dan Mathews Red Canyon Mine Structure Examination page 4 heaving. As far as I could tell, basement level bearing walls are placed on the slab-on-grade without expansion voids. No caisson elements were apparent as a portion of the foundational system. As was apparent in your photographs from your initial inspection, sotne minor drywall cracking and some separation of drywall from log posts does exist within the upper stories of the Truitt residence. The minor distress and movement may be the simple result of drying of the lazge structural log metnbers. Timbers can contract and shrink considerably, particulazly when exposed to hot-air heat. My examination of the basement level of the Truitt residence detected much less cracking within the newer drywall and tape finish of the basement level. While newer, Mr. Truitt believes most of that finish to be at least several years old. I suspect that because the basement level is within the concrete foundation walls it is not exposed to the minor movements associated with log desiccation and contraction. The grading and vegetative landscape treatment surrounding the Truitt structure appears mature and capable of promoting runoff away from the foundation for a large portion of the structure's periphery. The ample grass cover also appears capable of promoting evapo-transpiration, which also tends to regulate infiltration and promote reduced soil moisture fluctuation. It is not possible for me to formulate any observations regarding the various reported movements of doors, or changes in door to door frame spacing. My on-site observations detected only one instance in which the door trim appeared to be offset. Most casement trim was tight and undeflected, suggesting that the misalignment or non-level installations were a result of original finish installation. Further, the resulting effects appear minor. Without the luxury of before and after photography, it is difficult to differentiate between original finish carpentry mismatches and post-finish structural movement or distortion. My examination detected no evidence of subsidence impacts upon the Truitt residence. The Truitt Trailer Home Your earlier photograph beneath the Truitt house trailer( #21 A) appeared to show disorientation of several of the concrete block stanchions constructed to support the house trailer. My field observations determined that two separate generation of leveling support exist beneath the structure. The older system consists of non-mortared concrete block pillars founded on large timbers placed on the ground surface with minimal preparation. Many of these pillars are not vertical and appear precariously perched on thee smaller width timbers on which they were founded. Wooden wedges are installed between the top of these pillars and the trailer steel framework. All of these wedges are tight.
