We have been provided with Construction Drawings, site photographs, site notes and antennae information. This information along with historical data was used in our analysis. AT &T is proposing to remove six (6) of their existing antennas and replace them with nine (9) new panel antennae. These new antennae along with existing antennae were included in our analysis. A complete list and description of the antennae are shown on sheet 4 of this report Our analysis confirms the following: • The adequacy of the existing structure to support the proposed loadings • Adequacy of the proposed railing attachments • Adequacy of the existing railing to support the proposed loadings • Adequacy of the structural details shown on the Construction Drawings. Conservative loading has been assumed such that minor variances from the above will not affect the stress results. An analysis was done for the basic tank structure. The analysis was performed using a design wind speed of 100 mph. Calculations demonstrate that the structure is capable of resisting the additional loads from the antennas. The foundation anchorage was evaluated for the above wind loadings and was found to be adequate for the additional loading. Based on our experience, the foundation should be adequate for the relatively small increase in loading.

El Hagen Engineering International, Inc Site Location : Prior Lake, MN Site ID : MNL03028 General Welding Notes 1. All welding, including weld procedures and welder qualifications shall be in conformance with AWWA D100 -96. 2. All welds in the tank and structural attachments shall be made in a manner to ensure complete fusion with the base metal, within the limits specified for each joint, and in strict accordance with the qualified welding procedure specifications. Weather and temperature conditions. Welding shall not be performed when the surfaces of the parts to be welded are wet from rain, snow, or ice; when rain or snow is falling on such surfaces; or during periods of high winds, unless the welder or welding operator and the work are properly protected. Welding shall not be performed when the base metal temperature is lower than 32 °F (0 °C) unless the base metal within a distance of four times the plate thickness (3 in. [76 mm] minimum) of the place where welding is to be started is preheated to at least 100 °F (37.8 °C) and this temperature is maintained for the distance ahead of the arc set forth above as welding progresses. It is recommended that no welding be done when the base metal temperature falls below 0 °F (- 18 °C). If welding is to be performed when the base metal temperature is lower than 0 °F (- 18 °C), the following special requirements are to be met. a. Low - hydrogen electrodes or low- hydrogen welding shall be used. b. The base metal along the length of the weld joint in the direction of welding shall be preheated to 200 °F (93 °C) and maintained as welding progresses for a distance of at least 36 in. (914 mm) from the point of welding or the entire weld joint length, whichever is less. In addition, the area extending on both sides of the weld joint a distance of four times the plate thickness, but not less than 3 in. (76 mm) or more than 6 in. (152 mm), shall be preheated to and maintained at 200 °F (93 °C) during welding.
