Dear Ms. Labovitz,
B+T Group is pleased to submit this "Appurtenance Mount Modification Report" to determine the structural
integrity of the antenna mount on the above mentioned structure.
The purpose of the analysis is to determine acceptability of the mount's stress level. Based on our analysis we
have determined the stress level for the mount under the following load case to be:
Existing + Proposed Equipment t _ Sufficient Capacity
Note: See Table 1 for the final loading configuration .:- -- 75.0% [PASS]
This analysis has been performed in accordance with the 2014 Florida Building Code, 5th Edition, based upon
an ultimate 3-second gust wind speed of 158 mph converted to a nominal 3-second gust wind speed of 123 mph
per section 1609.3.1 as required for use in the TIA-222-G Standard per Exception #5 of Section 1609.1.1.
Exposure Category C and Risk Category II were used in this analysis.
All modifications and equipment proposed in this report shall be installed in accordance with the attached
drawings for the determined available structural capacity to be effective.
We at B+T Group appreciate the opportunity of providing our continuing professional services to you and
Smartlink, LLC. If you have any questions or need further assistance on this or any other projects, please give
us a call.

Page 3
The mount consists of T-Frame mounts attached to the Self Support Tower at 6080 Peterson Road, Fort
Pierce, FL 34947 in Saint Lucie County.
The proposed and existing antenna loading information was obtained from the RFDS dated 01/17/2017,
provided by Smarklink, LLC. All information provided to B+T Group was assumed accurate and complete.
2) ANALYSIS CRITERIA
The structural analysis was performed for this T-Frame mount in accordance with the ANSI/TIA-222-G-2-
2005 Structural Standard for Antenna Supporting Structures and Antennas -Addendum 2 using an ultimate
3-second gust wind speed of 158 mph. A point live load of 500lbs was applied at the center and ends of the
mount. The analyzed loading is detailed in Table 1.

Proposed Loading
3.1) Analysis Method
RISA-3D, a commercially available analysis software package, was used to create a three-dimensional
model of the mount and calculate member stresses and deflections for various loading cases. Selected
output from the analysis is included in Appendix A.
3.2) Assumptions
- `"--1)—The,mount was built in accordance with the manufacturer's specifications. - -
2) The mount has been maintained in accordance with the manufacturer's specifications and is free of
damage.
3) The configuration of antennas, mounts and other appurtenances are as specified in Table 1.
4) All mount components have been assumed to be in sufficient condition to carry their full design
capacity for the analysis. Refer to the issued mapping for any structural and/or maintenance issues
found during the site visit.
5) 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.

6) Mount areas and weights are determined from field measurements, standard material properties,
and/or manufacturer product data.
7) The following material grades were assumed:
a) Connection bolts: A325N
b) Pipe grade: A53-13-35
c) Angle grade: A36
d) Tube steel: A500-42

4.1) Structural Notes:
1) All modifications proposed in this report shall be installed in accordance with the attached drawing
for the determined available structural capacity to be effective.
2) If the loading differs from that described in Table 1 of this report or the provisions of this analysis are
found to be,invalid, another structural analysis should be performed.
3) B+T Group certifies that carrier's entire antenna structure will support the equipment deployment.
4) No erection or modification of the structure shall be made without approval of the structural
engineer.
5) Existing Equipment mounted on the Tower Legs will require relocation to the Sector Mounts to allow
space for modification installation.
