Written by GovTribe AI ·

This is Addendum #1 to a contract for Madison County, Illinois, related to the 800 MHz Digital Mobile Radio System Replacement project. The addendum provides technical specifications and engineering documentation for a 190-foot self-supporting vertical (SSV) tower installation at the primary Edwardsville, Illinois site. The attachments include an electrical site plan scaled at 1" = 30'-0" prepared by Kirk M. Meyer (Illinois Professional Engineer License 062-056289, valid through November 30, 2017), a tower analysis program output, and anchor bolt specifications for the foundation system.

The tower analysis was conducted using the TSTower v5.6.0 analysis program in accordance with ANSI/TIA-222-G-2005 design standards for Structure Class II in Exposure Category C. The design specification accounts for a basic wind speed of 90 mph without ice load and 40 mph with a 0.50-inch ice thickness. Maximum base reactions are documented as 219.6 kips download, 188.8 kips uplift, 21.6 kips shear, and 3,760.8 foot-kips overturning moment. The foundation requires six 1-inch diameter by 70-inch long anchor bolts (18 total). These technical specifications establish the structural requirements for integrating Motorola DMR trunked radio equipment at the tower site as part of the system replacement initiative.
