Robert Beissel Homes LLC <br /> Ulteig Project No.208.0987 <br /> July 10,2008 <br /> Page 3 <br /> 2. The following information is noted in regard to the observed foundation distress: <br /> a. Based on the orientation and location of the distress, the cracks are likely the result of <br /> minor differential settlement and / or frost heave, as well as potential intemal <br /> shrinkage stresses inherent in concrete construction. The size of the larger crack may <br /> also be due to the possible lack of a continuous horizontal reinforcing bar near the <br /> top of the wall at this location. <br /> b. Regardless, foundarion walls are intended to span vertically between supporting <br /> floor systems. The primarily vertical nature of the observed crack, as well as the <br /> corner and intersection locations, do not reduce the ability for the walls to support <br /> exterior grade and vertical house loads as intended, and ensures the continued <br /> adequacy of the existing foundation walls to support all required design loads. <br /> c. Waterproofing is typically flexible enough to span over small foundation wall cracks <br /> if installed in accordance with the manufacturer's requirements. If the builder is <br /> concerned with water infiltration, Ulteig recommends injecting the larger vertical <br /> crack in the rear lookout wall with a urethane injection material to help reduce the <br /> potential for future water infiltration. Other sealing methods may also be suitable <br /> for the condition noted. Ulteig is not responsible for current or future water <br /> infiltration problems <br /> PROFESSIONAL OPINION <br /> 3. It is our professional engineering opinion that the existing distress does not affect the <br /> structural integrity of the foundation. No structural corrective measures are required. Refer <br /> to the above recommendations for additional information. <br /> GENERAL <br /> 4. The informallon, observations, and opinions stated in this report are based on an inspection <br /> made by Trevor Axner, PE. The inspection consisted of a visual walk-through observing <br /> exposed elements and those accessible without the removal of finished materials. <br /> 5. The observations and opinions expressed in this report are based on our professional <br /> engineering judgment and professional practice, as well as the visual inspection. <br /> 6. No other engineering was performed or requested for this project. This document pertains <br /> to a structural review of the cast-in-place concrete foundation only. The builder may <br /> monitor the foundation for additional movement. If additional movement occurs, please <br /> contact a geotechnical engineer for a soil related review. <br /> 7. All construction is to be in accordance with the Code and standard industry practice. <br />
