Subject:Structural Assessment CITY OFT IGARD

Location: 6975 SW Sandburg St.

AT&T has requested that FDH Velocitel evaluate the structural feasibility of adding appurtenances on
the rooftop sleds of the building at the above referenced address. Existing and proposed appurtenances
by AT&T are as follows:
Existing Configuration of AT&T Appurtenances
Antenna/TMA/RRH Mount Coax and/or Fiber
(3) Kathrein 80010766
(3) Kathrein 80010765 (6)7/8" Coax
(3) CommScope DPA-65R-BUUUU-H8 Antenna Sleds +
(4) E15Z01P03 (6) RET Cables
(2) LGP 21401
(3) RRH2x40W-07L
(3) RRH2x60-1900A-4R Antenna Sleds N/A
(3) RRHx40-AWS+RDEM
(3) RRH4x25-WCS-4R
(3) DC6-48-60-0-1E Antenna Sleds (3) Fiber(6) DC cables
Proposed Configuration of AT&T Appurtenances
Antenna/TMA/RRH Mount Coax and/or Fiber
(3) RRH2x60-850 Antenna Sleds N/A
All proposed equipment will be installed on the existing rooftop sleds,and the wind and gravity loads
due to the RRHs will be negligible when compared to the loads on the entire building structure.This is
based on the previous structural analysis by JBE dated 3/2/16 and drawings by JBE dated 6/23/16.
Because of this, no further analysis of the building structure is required,and the proposed additions and
alterations can be implemented with the conditions outlined in this letter.Should you need any
clarifications or have any questions, please contact Paul Tibbot, P.E. at(503)310-9225.
