Subject: Structural Analysis of an Existing Self -Support Tower <br />Site: Arden Hills Self -Support Tower <br />Address: 1296 County Road F <br />Arden Hills, MN <br />Job No: R10.00098 <br />Page 3 <br />hardware. The mapping was also completed to determine if any antennas, microwave <br />dishes, and coaxial cables are currently not in use and could be removed from the tower. <br />From the mapping it was determined that there are (2) existing coaxial cables running up <br />the tower to an elevation of 240' that are currently not in use. Due to the quantity and <br />location of these existing unused cables, removing them will not have significant impact on <br />the tower loading. <br />Tower Inspection: <br />As per the request, a visual inspection of the existing above grade elements of the tower <br />was completed by Omni Contracting. The following is a result of the visual inspection. <br />Tower Members: From the inspection it was not apparent that any members were missing <br />or damaged. <br />Finish: From the inspection, rusting of the tower members was not apparent. However, it <br />was noted that the paint at certain areas of the tower was starting to flake. <br />Lighting: From the inspection, the existing tower lighting and wiring were in place and <br />appeared to be in good condition. <br />Grounding: From the inspection, the grounding wires for the antennas, microwave dishes, <br />and coaxial cables were in place and attached to the structure. <br />Antennas & Coaxial Cables: The existing antennas, microwave dishes, coaxial cables, and <br />antenna mounts were in good condition and appeared to be adequately secured to the <br />tower. <br />Concrete Foundations: A below grade inspection of the foundation was not completed. <br />Therefore, the condition of the existing tower foundations could not be verified and is not <br />covered in this report. <br />Risk Assessment: <br />Due to the location of the tower in relation to a new proposed multi -family housing <br />development, it was requested that a risk assessment of the existing tower be completed. <br />Per the results of the visual inspection and subsequent structural analysis, it is our <br />professional opinion that the proximity of the existing tower, in relation to the proposed <br />housing development, presents no significant hazard due to structural failure of the tower. <br />However, it should be noted that this statement only addresses the tower and existing <br />appurtenances and does not cover any items located below grade that were not analyzed or <br />inspected, such as the existing tower foundation. It should also be noted that this <br />statement is valid only for the loading conditions and design code that this tower was <br />analyzed for and that if additional appurtenances are added, if the tower is modified, or if <br />
