Box 106169 Atlanta, GA 30348-6169 RE: Your claim number: 43-619R-608 Simpson Engineering file number: 15.164 Spoon residence, 5756 N. Dixie Blvd, Odessa, TX 79762 Water Damage Investigation Dear Mr. Nelson: At your request I inspected the Spoon residence on April 23, 2015 to assess reported structural or foundation damage caused by plumbing leakage. I was accompanied on the inspection by Mrs. Spoon and contractor Cal Spoon. Drawings and photographs are attached showing the observed conditions. Background The Spoon residence is a one-story, single family house of wood frame construction. The exterior finish is vinyl siding. Interior finishes are drywall with plywood paneling in the living room. The house has a pier-and-beam foundation which consists of concrete block perimeter beam and interior piers, supporting the structural wood floor frame and subflooring. For orientation purposes, the house is assumed to face west. It was built in 1960, according to the Ector County Appraisal District. Mrs. Spoon reported the following: She purchased the house in 1970. The rear bedroom addition, which has a similar pier-and-beam foundation, was in place at that time (photo 4). About ten years ago the garage was converted into a bedroom (photo 3). The interior of the house also was renovated, including new tile flooring and cabinets in the kitchen (photo 53). In March 2015 a hot water pipe leak was discovered in or under the wall between the kitchen and bathroom (refer to Drawing One). The leak was discovered when the interior of the house became hot and humid. The leak was repaired twice and additional leak repairs may be needed. Water for the Spoon residence is supplied by a private well, so there are no water bills to show water consumption history.
Inspection I inspected the interior and exterior of the house, including the foundation crawlspace. Visual examination was made of accessible materials and areas pertinent to this investigation. The inspection did not include destructive or invasive testing of materials or removal of appliances, furnishings, or wall and floor coverings. At the time of my inspection the kitchen cabinets and appliances had been removed (photo 18), along with portions of the drywall behind the cabinets and the plywood boards which had been under the cabinets (photo 20). Photo 53 shows the kitchen interior before the removal. On the exterior of the house I observed no evidence of structural movement or damage, and no gaps or separations between the original house and the rear addition and converted garage. Inside the house there are no significant drywall cracks. There is moisture damage to the drywall on both sides of the stud wall where the leak occurred (photos 18 and 16). All interior and exterior doors are functional. The door to the bathroom fits and latches properly (photo 11), but the bottom of the door drags on the floor (photo 12). The scrape mark caused by this dragging appears new, indicating there has been some recent distortion of the floor structure in that area (photo 43). The finished hardwood flooring in the living room does not show significant cupping or ridging due to moisture absorption (photos 10-14). The wood plank subfloor under the hardwood floor also does not show moisture damage (photo 46). In the kitchen, the floor slopes down from the center and rear toward the kitchen sink area, but the finish tile flooring is not cracked (photo 17) and the tile backsplash around the sink area is not cracked (photo 21). Inspection of the foundation crawlspace revealed significant past foundation repairs, including supplemental concrete blocks and shims and supplemental wood framing under the kitchen floor (photo 34). At the wall between the kitchen and bathroom the stud wall framing shows water leak staining but no structural water damage, and it should be noted that there is no water damage of any kind to the new lumber which was installed in that area when the kitchen was remodeled several years ago (photos 18, 31 and 32). Under the bathroom, there has been prior reconstruction of the floor framing (photos 37 and 40) and supplemental foundation support (photo 41). As in the kitchen remodel area, the newer lumber under the bathroom does not show any water damage. I observed a drip leak under the west end of the wall between the kitchen and bathroom kitchen (photo 38). There are no visible pipes or leak sources under the house at this location, so it appeared that the drip leak is in the plumbing stack wall. This observation is consistent with the owner s statement that additional leak repairs were expected. I made a topographic survey of the foundation using a laser level. Individual point elevations were measured throughout the house. The point elevations were adjusted to compensate for differences in floor covering thickness. The point elevations were then used to develop the surface elevation contours. The foundation is relatively level in most areas, except for a dip or sag area in the kitchen and bathroom. Total difference in elevation is 2.1 inches, measured between the highest point at the northwest front corner of the house and the lowest point in the kitchen-bath interior (refer to Drawing Four).

The floor profile is shown pictorially on Drawing Five. It should be noted that on this drawing the vertical elevation differential has been magnified by a factor of ten to make the floor profile more discernible. If the floor profile were plotted without the vertical scale magnification, the floor would appear much flatter. Built-in split level conditions are not depicted. Analysis The facts and observations cited above show that the Spoon house has a history of foundation settlement and foundation repairs in the kitchen-bathroom area. The lack of significant cracking or gapping of the interior finishes indicates there has been minimal new movement. The effects of the recent hot water leak must be considered in this context. For example, the bathroom door still fits and latches but now drags the floor where it did not drag prior to the leak event. The lack of structural water damage to the stud wall framing and floor framing, especially the lack of damage to the remodel lumber, indicates that the leak was of relatively short duration and size. This conclusion also is indicated by the lack of notable cupping or warping of the hardwood flooring. Damage Summary and Repair Recommendations Repair all plumbing leaks and obtain a plumbing test report stating that there are no more active water or sewer leaks. Refer to Drawing One for the area affected by the recent water leak event. The following repair recommendations apply only to that area. 1. Drywall: replace water-damaged drywall on both sides of the stud wall between the kitchen and bathroom. 2. Stud wall framing and structural wood subfloor and joist framing: no water leak damage. 3. Finish hardwood flooring in living room: no water leak damage requiring removal or replacement in any area. Minimal surface ridging in the living room can be corrected by sanding and refinishing. 4. Finish flooring in kitchen, bathroom and other rooms - no water leak damage. 5. Foundation: Limited foundation adjustments (jacking and shimming) are needed under the kitchen and bath. The soil under the house must be completely dry and firm before foundation adjustments can be accomplished. The leak-related floor and foundation distortion can be repaired by corrective shimming individual existing concrete blocks. No new concrete blocks are required. No lumber or framing replacement is required. It is important to note that the house was not level prior to the recent plumbing leak, and that the interior and exterior finishes had been previously adjusted to fit the existing conditions. Therefore, the corrective leveling should be limited to restoring the foundation to its pre- Simpson Engineering file 15.164 - Spoon - State Farm Insurance claim number 43-619R-608 Page 3
leak profile. Care should be taken not to overcorrect; excessive jacking or leveling could cause new damage. Summary The following conclusions are indicated by the engineering facts and observations which are presented in this report: 1. The Spoon house has a history of foundation settling problems. There have been prior foundation repairs and structural floor framing repairs. 2. The recent water leak event caused non-structural water damage to drywall and cabinetry in the leak area (refer to Drawing One). Foundation adjustments are needed in the leak affected area. A scope of necessary water damage repairs is included in this report. Please let me know if I can be of further assistance in this matter. Edward M. Simpson, P.E.
