Joy,
DK Structural Engineering, LLC (DKSE) is pleased to submit this "Battery PE Letter R1" for the above-
referenced site based on the following documents:
1. RFDS provided by Verizon Wireless Site ID: 393701, dated 10/28/2022
2. CDs provided by Lutz, Daily & Brain, LLC Project Name: "CO3 Aspen Highlands - Rev C"
Removed Cabinet Loading: Proposed Cabinet Loading:
• (2) CDMA Cabinets (2200 Ibs) • (20) Deka HT200ET Batteries (3020 Ibs)
• (12) Batteries (1587.6 Ibs) • Battery Half Rack (250 Ibs)
DKSE has determined that the proposed loading changes are O.K. by comparison to the original design.
Proposed Loading Passing
The proposed changes to the cabinet result in a decrease in vertical forces and no change in lateral forces and,
therefore, are acceptable per IBC. Original design and existing loading are assumed to be approved by a
licensed engineer for applicable building codes and jurisdiction design criteria.
This letter is not intended to replace any rigorous design or analysis of the existing cabinet platform, and
associated connections. No other changes to the loading, other than listed herein, shall be made without
verification by a licensed engineer.
We appreciate the opportunity of providing our continuing professional services to you. If you have any
questions or need further assistance on this or any other projects, please send us an email.
