(3) Site Pro 1 Stacked 10'-10" T-Arms - Structural Evaluation Site USID #: 214755 <br /> <br />3/1/2023 Page 4 of 4 <br />DISCLAIMER OF WARRANTIES <br /> <br />GPD has not performed a site visit to the mount to verify the member sizes and antenna/coax loading. If the existing <br />conditions are not as represented on the mount elevation contained in this report, we should be contacted immediately to <br />evaluate the significance of the discrepancy. This is not a condition assessment of the mount. This report does not replace <br />a full mount inspection. The mount is assumed to have been properly fabricated, maintained, in good condition, twist free, <br />and plumb. <br /> <br />The engineering services rendered by GPD in connection with this Mount Analysis are limited to a computer analysis of the <br />mount structure and theoretical capacity of its main structural members. All mount components have been assumed to only <br />resist dead loads when no other loads are applied. No allowance was made for any damaged, bent, missing, loose, or <br />rusted members (above and below ground). No allowance was made for loose bolts or cracked welds. <br /> <br />This analysis is limited to the designated maximum wind and seismic conditions per the governing mount standards and <br />code. Wind forces resulting in tower vibrations near the structure’s resonant frequencies were not considered in this analysis <br />and are outside the scope of this analysis. Lateral loading from any dynamic response was not evaluated under a time - <br />domain based fatigue analysis. <br /> <br />GPD does not analyze the fabrication of the structure (including welding). It is not possible to have all the very detailed <br />information needed to perform a thorough analysis of every structural sub-component and connection of an existing mount. <br />GPD provides a limited scope of service in that we cannot verify the adequacy of every weld, plate connection detail, etc. <br />The purpose of this report is to assess the feasibility of adding appurtenances usually accompanied by transmission lines <br />to the structure. <br /> <br />It is the owner’s responsibility to determine the amount of ice accumulation in excess of the specified code recommended <br />amount, if any, that should be considered in the structural analysis. <br /> <br />The attached sketches are a schematic representation of the analyzed mount. If any material is fabricated from these <br />sketches, the contractor shall be responsible for field verifying the existing conditions, proper fit, and clearance in the field. <br />Any mentions of structural modifications are reasonable estimates and should not be used as a precise construction <br />document. Precise modification drawings are obtainable from GPD, but are beyond the scope of this report. <br /> <br />Towers are designed to carry gravity, wind, and ice loads. All members, legs, diagonals, struts, and redundant members <br />provide structural stability to the tower with little redundancy. Absence or removal of a member can trigger catastrophic <br />failure unless a substitute is provided before any removal. Legs carry axial loads and derive their strength from shorter <br />unbraced lengths by the presence of redundant members and their connection to the diagonals with bolts or welds. If the <br />bolts or welds are removed without providing any substitute to the frame, the leg is subjected to a higher unbraced length <br />that immediately reduces its load carrying capacity. If a diagonal is also removed in addition to the connection, the unbraced <br />length of the leg is greatly increased, jeopardizing its load carrying capacity. Failure of one leg can result in a tower collapse <br />because there is no redundancy. Redundant members and diagonals are critical to the stability of the tower. <br /> <br />GPD makes no warranties, expressed and/or implied, in connection with this report and disclaims any liability arising from <br />material, fabrication, and erection of this mount. GPD will not be responsible whatsoever for, or on account of, consequential <br />or incidental damages sustained by any person, firm, or organization as a result of any data or conclusions contained in this <br />report. The maximum liability of GPD pursuant to this report will be limited to the total fee received for preparation of this <br />report. <br />4111 3%4 S Main St Unit <br />#WCC0112/13/2024
