This structural analysis was performed to address the adequacy of the existing tower to safely support the existing/proposed loading. Based on the governing load case listed within this report, we have determined that the tower structure is: Existing + Proposed Equipment Tower Structurally Adequate (46.6%) Note: See Analysis Criteria for loading configuration Foundation Structurally Adequate This structural review has been performed in accordance with the TIA-222 Standard, ASCE 7, and the International Building Code. These results are based on the existing loads with the proposed loading as listed within this report. Should the design criteria, proposed loading or configuration change, the tower should be re-analyzed based on the new proposed configuration. Based on the attached scope of work the existing tower was analyzed to determine its structural adequacy for the proposed loading. We at Powder River Development Services, LLC appreciate the opportunity to provide engineering services for this project. Please contact us should you have any questions or require any additional information regarding this report.
