T have also reviewed the drawings that you provided,illustrating <br /> the proposed•addition of a new second floor over the.existing structpre, The.purpose of <br /> my visit was to judge the wall condition and the propbsed work and to providean opinion <br /> concerning.the adequacy of the existing 8" block'walls to.support the tctal.loa.ds.of"the <br /> existing and pew construction- • <br /> • <br /> 1 noted that the existing foundation walls were constructed as 10 course high wallsand <br /> • were in nearly all cases that Could be measured,•8" nominal width. Nominal 1.2".walls. ' <br /> '..— were noted in the small.room that contained the oil tank. The existing walls support the <br /> weight imposed by the.first floor and the roof. The walls at the north'side of the house <br /> • support the gravity loads as well as lateral soil loads for nearly their full height... All of . <br /> the walls will support the weight of an additional floor after the construction of the <br /> proposed second floor. , . . <br /> ' ; I have performed calculations to determine the loads on.the existing foundation wails :. <br /> ' , imposed by the new construction. I find that the loads imposed will ncit exceed the . <br /> . capacity of the existing walls. I have.also,considered the condition of the existing ' <br /> • foundation walls and it is'my opinion that the existing 8" masonry walls will perform <br /> properly. . . • <br /> If you have any questions or comments concerning the above, please do not hesitate to - <br /> contact me. <br /> Sincerely. <br /> Mattson/Macdonald, Inc. i hereby certity that thIS plan, specification, or report <br /> 1/7/(-1 was prttpusrsd ay me or undar rry direct avperysoon <br /> / Qnri lha am a duly Relt?et ed•:'roter.stonst EniTneer .1 <br /> nd® E we of the Stater of Minnes0ta- <br /> 1)a'id H.
