The new owner wishes to remove the existing roof and add full span main level <br /> floor trusses and full span bonus room trusses to the exterior foundation walls. <br /> 2. The following information is noted in regard to the above observed conditions: <br /> � <br /> a. Based on the above observations,the full height foundation system does not ! <br /> appear to be affected by significant settlement. Water is getting into the <br /> ! <br /> foundation system, however,the foundation walls do not appear to be in an � <br /> unsafe condition despite the water intrusion and cracking. The condition of the <br /> exposed foundation walls seem suitable for reuse and should provide adequate f <br /> support for the remodel provided all forms of water mitigation are implemented ' <br /> and reinforcement of the bowing/cracked areas are conducted. <br /> b. The cracks noted along the areas of the exposed foundation walls should not � <br /> affect the structural integrity after futly grouting, reinforcing, and tuck pointing. � <br /> All areas of cracking shall be solidly grouted and the damaged courses replaced <br /> or formed and poured. Any cracks that are exposed are to be treated and ; <br /> adequately protected from further water intrusion that may cause freeze-thaw ; <br /> action or further widening. ! <br /> i <br /> c. The rear foundation wall should have all cores solidly grouted the full height of i <br /> the wall at the bowed areas. An alternative would be to reinforce the wall with � <br /> #4 vertical bars solidly grouted @ 16"on-center. � <br /> d. It is proposed that an additional course will be added to the existing foundation <br /> wall upon removal of the existing floor structure. Upon removal of the floor � <br /> structure,the entire top course shall be fully inspected by the contractor and <br /> fully grouted. The new to existing coursing shall have adequate dowels and/or i <br /> anchor bolts not in excess of 32"on-center spacing. <br /> e. The minimum perimeter concrete footing size of 16"wide shall be adequate to ; <br /> support the proposed remodel. This minimum footing size assumes an allowable <br /> bearing capacity of 2,000 pounds-per-square foot of suitable bearing soils. Field � <br /> verify existing bearing soils to the rear of the property that adequate soils are i <br /> present. These foundation sizes and loads were determined by analyzing the � <br /> load paths on the provided drawings from Behr Design Inc. Significant point ! <br /> loads should be avoided to prevent major shifting or adjusting. � <br /> f. The rear crawl space area is to have grout installed at all crack locations. <br /> Damaged blocks shall be removed, replaced,or formed with solid concrete. The j <br /> rear foundation is to have shallow frost protected insulation measures installed <br /> in accordance with the attached S1 sheet. <br /> g. The long term performance and lifespan of the foundation watls will be affected <br /> if all forms of water mitigation are not utilized and maintained. Without , <br /> complete water mitigation, a foundation system has the potential to be � <br /> � <br /> i <br /> i <br /> i <br /> I <br />
