It is my understanding that these modifications include re- <br /> building the main tevel and adding a new upper level. See the attached plan for reference to the <br /> following notes: <br /> 1, A horizontal crack occurs at a C.M.U.bed joint 5'-4" above the slab on grade. This crack has <br /> been patched in ihe past and has continued to move. This wa![is laterally unstable and <br /> requires repair or replacement, The repair may include removing the exterior grade, <br /> removing portions of the interior face shell and reinforcing the wall as required. Since no <br /> . balancing earth pressure is available from the lake side, helical anchors through the wall <br /> toward the street may be used to resist these pressures. <br /> 2_ A fiered ledge occurs in ihe foundation wall. I am unable to deteRnine the reason forthis <br /> consiruction. However,wall consiruction of this type is rareiy suitabfe for re-use. This area <br /> must be replaced. <br /> 3. The garage slab on grade as settled and cracked. <br /> � 4. The grade inside the garage is 5' higherihan outside this wall. The iop of the wall has been <br /> pushed out approximaiely 1 '/:"due to interior soil pressure. This wall requires repair or <br /> , replacement, One method to repair this wall is to add reinforcing as indicated in item number <br /> 1 and add helical anchors through the wall and underthe garage slab. A portion of the <br /> garage slab must be removed for this repair. � <br /> 5. The grade inside the garage is 7'to 8' hlgher inside the garage than in the basement. The <br /> first floor diaphragm has bowed noticeably toward the lake due to the soif pressure from the <br /> garage. The side walls and floor diaphragm do not provide adequate resistance for the soil • <br /> pressure, This wall requires repair or replacement. One method to repairthis wall is to add <br /> reinforcing as indicated in item number 1 and add helical anchors through the walf and under <br /> the garage slab. A portion of the garage slab must be removed for this repair, <br /> In general,the st'reet side walls �equire reinforcing and the use of helical anchors projecting <br /> toward the street to resist lateral earth pressures. The side wall of the garage requires similar <br /> repair going underthe slab. The anchor plates would be visible from outside the house. The <br /> repairs may not correct the �oticeable movement ihat has occurred in the walls and floor <br /> structure. Once these repairs are made to stabilize the walls, additional reinforcing <br /> (walls/footings) may be required to support the new construction. <br /> � Please call me if you have any questions cnncerning the above. <br /> Sincerely, <br /> A.M.
