I have been to the site to observe the existing <br /> conditions and have performed calculations in accordance with the Minnesota State Building Code for the <br /> proposed addition and modification to this structure. You provided me with copies of floor plans from the <br /> original building and a copy of the plans, elevations and sections for the proposed new construction. <br /> As a result of my review and calculations I have found that the existing footings and foundations will be <br /> capable of supporting the anticipated loads from the new construction when repairs have been made to <br /> correct the cracking of the masonry foundation walls. <br /> I have provided you with drawings numbered S1 thru S4 that illustrate several options for repair of these <br /> walls. I have also provided you with a plan drawing that illustrates the modifications to be made to the <br /> existing first floor framing that will allow you to eliminate the columns in the basement. I have also provided <br /> a drawing that has our typical structural notes for residential construction related to this work and a detail that <br /> may be used for a flush beam condition at the floor. <br /> If you have any questions concerning the above, please do not hesitate to contact me. <br /> Sincerely, <br /> I hereby ecrtify that this plan,specification or report was prepared <br /> Mattson Maedonald Young, (f1C. by me or under my direct supervision and[hat 1 am a duly licensed <br /> Professional Engineer undcr the laws of the State of Minnesota. <br /> �� � � ��.r y��� <br /> David H.Macdonald P.E. <br /> David H.
