Structural Analysis of NPS Radio Tower at Robertson Research Center, July 2009

Everglades National Park was contacted by SBA Network Services on behalf of Verizon Wireless in April 2009 to inquire about co-locating cellular telecommunications equipment on the park owned tower.

Verizon Wireless arranged for a structural analysis of the tower to determine its condition and whether it could support additional equipment. The consulting engineering company, Morrison Hershfield, completed an evaluation of the tower to determine compliance with Revision G (Florida Building Code) for 146 miles per hour winds in 3 second gusts. The results of the analysis concluded the tower was already over-stressed 191 % without the addition of new equipment.

Based on the structural evaluation, the park could not consider co-location and needed to determine a path forward to replace the tower to continue to support park operations.
