Memorandum Date.: January 10, 2012 To: Annie Deckert City of Elk River 13065 Orono Parkway NW Elk River, MN 55330 From: Jason S. Hanlon, PE, SE Re: Site Observations -Jan. 5, 2012 7.24 Main St. Elk River, MN Project BL-11-06693 hereby certify that this plan, specification or report was prepared by me or under my direct supervision and that I am a d ly licensed pro ssional engineer under the he Stat ne a. Jason S. Hanlon Date: 1/10/12 Minnesota Registration No. 41941 This memo is in regards to the site visit that were completed by Jason Hanlon, of Braun Intertec, on January 5, 2012 to observe the current conditions of the demolition and the existing, exposed conditions of the east wall of the 724 Building. The wall in question appears to be in relatively good condition with no significant signs of distress or settlement. There are some areas where the mortar in the joints is lacking and could use some tuck- pointing, but overall the condition of the wall is good and in our opinion does not require significant structural repair. The following items need to be addressed moving forward: - It was determined that the foundation depth along this wall is only 22-inches below grade and will require some additional frost protection since this wall is now exposed to external temperatures on the east side. Braun Intertec provided a detail (S1, dated 1/9/12) for this condition for the City to implement. - The exterior face of the east wall needs to be weatherized. This wall has not experienced external conditions in some time, or if at all, and needs to be updated to provide the appropriate protection. This may include, but not limited to, water proofing of the exterior face through possible exterior finishes (i.e., stucco), updating the flashing along the parapet and at the front and rear corners of the building, and infill of bearing pockets and openings accordingly. Braun Intertec is available to help with preparing corrective measure details for the conditions noted above. Please contact us if the City would like additional assistance with this matter or need any other evaluations completed. Please let me know if you have any questions.
