Dear Mr. Norville:
We have reviewed the referenced site for the purpose of stating our structural opinion on the capacity
of the existing building rooftop to support the final T-Mobile equipment loading. The following
information was provided to us or obtained for this letter:
• The existing Pipe Mount information was obtained from:
- The Structural Analysis prepared by GPD Group, Inc., dated June 14, 2017.
- The site photos provided by T-Mobile subcontractors.
• The existing and proposed antenna loading information was obtained from the Anchor Upgrade
Construction Drawings prepared by First Group Engineering, dated September 15, 2020.
APPLICABLE STANDARDS & CODES
2018 International Building Code
Based on a comparison, the proposed effective weight for the final loading is within tolerances of the
allowable design loading. We conclude the final T-Mobile loading will not have an impact on the
structural integrity of the building structure.
If any questions arise from your review, please call us at your earliest convenience.
Sincerely,
FORESITE GROUP LLC

WEIGHT COMPARISON
The total weight of the equipment loading in approximately 2,590 lbs. The total distributed load from the
platform to the rooftop supporting structure is 18.8 psf. Per current code, the allowable design live load
for the roof is assumed to be 20 psf. We conclude that the existing building rooftop is adequate to
support the existing and proposed T-Mobile equipment platform Loading.
CONCLUSIONS & RECOMMENDATIONS
Based on a comparison, the proposed effective weight for the final loading is within tolerances of the
allowable design loading. We conclude the final T-Mobile loading will not have an impact on the
structural integrity of the building structure.
