October 21, 2025 T-Arm Mount Analysis Main / Dyer (CLL03413) TEP Project Number 272252.1169408 Page 3 Table 4 - Documents Provided Document Remarks Source Previous Mount Analysis DCI Pacific dated 9/30/2021 Site Number: CLL03413 M Squared Scoping Form AT&T Mobility, dated January 21, 2025 RFDS ID: 35051 M Squared Preliminary Construction Drawings M Squared Project No. 10086996 M Squared Correspondence Correspondence from M Squared Wireless in reference to the existing, proposed, and reserved loading. M Squared RECOMMENDATIONS 1) If the load differs from that described in Table 2 of this report or the provisions of this analysis are found to be invalid, another structural analysis should be performed. 2) The mount and its connection have sufficient capacity to carry the existing and proposed loading configuration. In order for the results of this analysis to be valid, the mount modifications listed below must be completed: a) Reuse existing mount pipe(s) in empty antenna positions, where an existing antenna is located or where an existing antenna is being relocated to. Reconfigure antenna mount pipe positions to 4 positions per sector per referenced construction drawings. b) Replace existing antenna mount pipes at position A3, B2 and C2 with (3) Site Pro P30120, 2.5 Sch.40 x 10-0 Mount Pipes (CONMAT Item No. ANT.16008) connected to the face horizontal with (3) Site Pro SP219-H Pipe Cross Support Plates (CONMAT Item No. ANT.55968) for proposed antennas. c) Install (6) Site Pro P2120, 2.0 Sch.40 x 10-0 Mount Pipes (CONMAT Item No. ANT.55993) to be connection to mount support arms with (3) Site Pro BBPM-U Universal back to back pipe mount assemblies (CONMAT Item No. ANT.58819) for RRU and surge mounting. ANALYSIS ASSUMPTIONS 1) The mount was built in accordance with the manufacturers specifications. 2) The mount has been maintained in accordance with the manufacturers specification. 3) The configuration of antennas, transmission cables, mounts and other appurtenances are as specified in Table 2. All mount components have been assumed to be in sufficient condition to carry their full design capacity for this analysis. Refer to the issued mapping for any structural and/or maintenance issues found during our site visit. 4) Serviceability with respect to antenna twist, tilt, roll, or lateral translation, is not checked and is left to the carrier or tower owner to ensure conformance. 5) TEP did not analyze the collar mount connection to the pole and assumes it to have sufficient structural capacity to transfer the applied forces from the mount to the tower. 6) All material grades used for this analysis, unless verified by mount manufacturer design, were assumed per AISC Table 2-4, 15th Edition. See RISA 3-D output for confirmation on grades used in this analysis. This analysis may be affected if any assumptions are not valid or have been made in error. TEP should be notified to determine the effect on the structural integrity of the mount.
