BKV <br />GROUP <br />ARCHITECTURE INTERIOR DESIGN LANDSCAPE ARCHITECTURE ENGINEERING <br />Tim Gladhill, AICP <br />City of Ramsey <br />7550 Sunwood Drive NW <br />Ramsey, MN <br />55303 <br />5/31/2019 <br />Dear Mr. Gladhill, <br />As requested, Kyle Olson, Associate Partner of BKV Group, visited Ramsey City Hall on May 23rd, <br />2019 to evaluate the City owned sign along Highway 10 that was damaged by a vehicle. Tim <br />Gladhill, City of Ramsey, provided existing documentation of the sign consisting of sketches and <br />structural calculations for the primary structure and foundation. Chloe Brigl, City of Ramsey, <br />provided access to the sign and accompanied Kyle for observation. <br />Primary sign structure consists of two cantilevered HSS12x12x1/2 steel tube columns that are <br />embedded into concrete piers. At least one horizontal steel tube connecting the two columns <br />was observed above the area of damage that occurred. Secondary framing supporting the <br />cladding consists of 2x wood members and plywood sheathing. Secondary framing is supported <br />entirely from the two primary columns with miscellaneous steel angle pieces connecting the <br />wood framing to the steel columns. There is a full -height pilaster of stone veneer adhered to the <br />secondary wood framing on the side of the sign opposite the highway. <br />Cladding and secondary framing located at grade and between the primary steel tube <br />columns was heavily damaged, requiring removal and/or replacement. The bottom section of <br />the stone pilaster was rotated due to vehicle impact. Primary structure (steel HSS) was not <br />damaged. <br />Secondary framing of the pilaster was only partially visible. Based on observations made, it could <br />not be determined if the secondary framing supporting the pilaster was constructed with a <br />properly engineered load path to resolve all possible load conditions into grade. Considering <br />the damage observed to the bottom of the pilaster, BKV Group recommends complete removal <br />and/or replacement of the pilaster. <br />Sincerely, <br />Kyle Olson, PE, SE <br />Senior Structural Engineer, Associate Partner <br />BKV Group <br />222 N 2nd Street, Suite 101 I Minneapolis, MN 55401 I 612.339.3752 I www.bkvgroup.com <br />
