The existing constructio�� of the property �s a single <br /> story wood frar�ed ha�se with r��asanry �concrete block} wafl crawf space foundation. Th� existing <br /> foundation is 5uitab�� fo� support af the new proposed two-s�4ry k�ot�se, The new structure should <br /> have an interiar beam firie tfl su�port th�e rnain ffc�or with t�e exterior walls used to suppori the <br /> second floor and roof framing. The existing foundation walls should be repointed in areas where <br /> cracking has occurred and stair step cracking areas shall be reinforced with #5 dowels grouted into <br /> vertical cores at the crack in the south-each corner and any other areas of stepping cracks of the <br /> wall. Please provide the proposed plans (including floor and roof truss shop drawings) so I can size <br /> the interior footings to minimize differential movement between the new footings and existing <br /> foundation. <br /> The plans I reviewed from Autumn Design show new foundation for the porch on the west end of the <br /> building. In this area there is a perimeter foundation wall in place. It is my recommendation to use <br /> the existing foundation and add interior footings as needed to support the f(oor instead of providing <br /> new piers and footings as shown on the current plan. <br /> On May 8, 2009 I was informed that the main floor level will have to raise 2.6' per the city of Orono. <br /> The existing foundation is sufficient to support this change. This would be best accompfished by <br /> adding 3 courses of concrete block to the top of the existing wall. <br /> Please feel free to share this letter with the local building officiaf and builder as required. You may <br /> contact me at (320) 259-6575 if you have any further questions or comments regarding this matter. <br /> Sin y <br /> yan� eavert, P.E.
