Dear Ms. Rodriguez:
APX Engineering Group, LLC (APX) has completed an evaluation of the effect on loading upon the
subject monopole tower created by installing certain new antenna equipment on the structure. This
evaluation was based on information gathered by our representatives in the field, published catalog
information, the original tower and foundation design by Sabre Communications Corporation dated April
9, 2020, and information provided by T-Mobile. This evaluation assumes that the existing structural
system components are in adequate condition to support their full design capacity. The intent of this
report is to assess the effects of the proposed installation on the supporting structure.
Our evaluation was based on the following proposed designations, sizes, and configurations of antenna
equipment as indicated by T-Mobile.
The proposed antenna equipment will be attached to the tower using a commercially available mounting
system rated for such applications. As indicated in the tables attached, the proposed antenna equipment
loading does not impose a load increase on the existing tower structure when compared to the original
design loading. Therefore, in accordance with the Florida Building Code – Existing, 7th Edition (2020),
Sections 807.4 and 807.5, the existing tower will support the proposed T-Mobile loading.
Should you have any questions or wish to discuss any aspect of this letter, please do not hesitate to
contact the undersigned.
Sincerely,
APX Engineering Group, LLC
