4 <br /> � Ton�Patterson <br /> ' November 3, 1999 <br /> � Page 2 of 3 <br /> OBSERVATIONS AND COMMENTS <br /> 1. A site visit was conducted by J. H. Dahlmeier of J. H. Dahlmeier Engineering <br /> Inc. on November 2, 1999 to review existing conditions. <br /> 2. The residence is a 30' x 32' single-family structure facing west with full <br /> basement constructed of concrete masonry and wood frame superstructure. <br /> The exterior masonry foundation walls are load bearing as well as the center <br /> wood load bearing wall running north and south all supported on concrete <br /> footings. <br /> 3. The foundation system consists of the following: <br /> a. The foundation system is constructed of concrete masonry 20" thick <br /> from slab to 5 feet above floor line and 8" thick for an additional 2 feet <br /> for a total of 7 feet. <br /> b. This condition is typical except the west half of the north wall, east <br /> half of the south wall (stairs) and 6 feet of the west wall (north end) <br /> which is constructed of 8" masonry. <br /> c. The inside surface of the wall has been parged. <br /> d. No significant movement or cracks were observed on the interior. <br /> e. On the exterior, small vertical cracks exist at the corners. <br /> £ A 6' x 6' storm cellar 7 feet high exists in the northwest corner below <br /> the basement floor slab. <br /> 4. A structural engineering analysis was completed with the following results: <br /> a. The foundation sections with 20" wide foundation wall are structurally <br /> adequate to support the new loads and existing earth pressure. <br /> b. The 8" thick foundation walls described in paragraph 3b are not <br /> structurally adequate. Corrective measures will be required. <br /> c. The storm shelter is structurally adequate. <br /> 5. No other structural engineering was directed or required including porch <br /> foundation system, floor framing and framing over storm shelter. <br /> CORRECTIVE MEASURES <br /> 6. The 8" masonry walls listed in paragraph 3b need to be grouted full with <br /> 2500 psi grout from footing to top of wall. <br />
