EXECUTIVE SUMMARY
At the request of SBA Network Services, Inc., FDH Velocitel performed a structural analysis of the existing Guyed Tower
located in Fort Pierce, FL to determine whether the tower is structurally adequate to support the antenna configuration in
place per Table 1 pursuant to the ANSIITIA-222-G Structural Standard forAntenna Supporting Structures and Antennas and
2014 Florida Building Code, P Edition. Information pertaining to the antenna loading, current tower geometry, member
sizes, and below grade parameters was obtained from:

The ultimate design wind speed per the 2014 Florida Building Code, 9° Edition, is 160 mph without ice. This is converted to
a basic design wind speed per the ANSIITIA-222-G standard and 2014 Florida Building Code, 51" Edition, Section 1609.3.1
of 124 mph. Furthermore, this structure was analyzed as a Class II structure in Exposure Category B with a topographical
factor of 1 and Spectral Response Accelerations of Ss = 0.055 and Sr = 0.029.
Note: Per Section 2.7.3 of the ANSIITIA-222-G Standard, the seismiclearthquake loading effects can be ignored if the
spectral response acceleration at short periods (Ss) is less than or equal to 1.00. The towers location mandates a design Ss
of less than 1.00, thus seismic loading was not considered as part of the analysis of this structure.
Conclusions
With the antenna configuration in place per Table 1 we have determined the tower stress level to be sufficient and the
foundation(s) to be sufficient pursuant to the requirements stipulated by ANSYTIA-222-G Structural Standard for Antenna
Supporting Structures and Antennas and 2014 Florida Building Code, 51h Edition. For a more detailed description of the
analysis of the tower, see the Results section of this report.
Our structural analysis has been performed assuming all information provided to FDH Velocitel is accurate (i.e., the structure
member information, tower layout, existing antenna loading, and proposed antenna loading) and that the tower has been
properly erected and maintained per the original design drawings.
Recommendations
To ensure the requirements of the current analysis standards are met with the antenna configuration in place per Table 1,
we have the following recommendations:

APPURTENANCE LISTING
The antennas and equipment, with their corresponding feed lines, considered for this analysis are shown in Table 1. If the
actual layout determined in the field deviates from the layout, FDH Velocitel should he contacted to perform a revised
anaysis.

November 10, 2016
The following material grades for individual members were,used for analysis:
Table 2 - Material Grade
Member Type Material Grade
L s I A572.60 Assumed
Bracing A36 Assumed
Table 3 and Table 4 display the summary of capacities for the analyzed structure and its additional components. Values
greater than 100% indicate locations where the maximum force in the member exceeds its capacity. Note: Capacities up to
105%are considered acceptable (except foundation soil interaction, up to 110% is considered acceptable).
If the assumptions outlined in this report differ from actual field conditions, FDH Velocitel should be contacted to perform a
revised analysis. Furthermore, as no information pertaining to the allowable twist and sway requirements for the
appurtenances was provided, deflection and rotation were not taken into consideration when performing this analysis.
See the Appendix for detailed modeling information.

GENERAL COMMENTS
This engineering analysis is based upon the theoretical capacity of the structure. It is not a condition assessment of the
tower and its foundation. It is the responsibility of SBA Network Services, Inc. to verify that the tower modeled and analyzed
is the correct structure (with accurate antenna loading information) modeled. If there are substantial modifications to be
made or the assumptions made in this analysis are not accurate, FDH Velocitel should be notified immediately to perform a
revised analysis.
LIMITATIONS
All opinions and conclusions are considered accurate to a reasonable degree of engineering certainty based upon the
evidence available at the time of this report. All opinions and conclusions are subject to revision based upon receipt of new
or additional/updated information. All services are provided exercising a level of care and diligence equivalent to the
standard and care of our profession. No other warranty or guarantee, expressed or implied, is offered. Our services are
confidential in nature and we will not release this report to any other party without the client's consent. The use of this
engineering work is limited to the express purpose for which it was commissioned and it may not be reused, copied, or
