The Village is pursuing a project to network the Emergency Operation Center (EOC) &
Public Works facilities at 1720 and 1700 W. Central Road via a wireless microwave link
from the downtown water tower. Currently, the EOC & Public Works buildings are
connected via fiber which travels through the 112 E. Northwest Highway former Publilt
Safety building and Block 56/Chase Bank site. Due to the fiber being owned by Wide Open
West (and not the Village) and the relocation of the Fire and Police, rerouting the existing
fiber link is not a viable solution. The wireless solution being considered will require
replacement of the existing antenna tower on • • of Public Works.
The current tower is original to the building. The new 79 foot tower will be constructed in
the existing spot and is approximately 40 feet taller to provide adequate line of sight for
optimal up time. The antenna needs a clear line of sight from the building to the water
tower
,, taking into account any buildings and topography in between. Additional details on
the line of site and topography, demonstrating the need for the antenna height, is included
in the attached Infrastructure Plan. The antennas are very reliable (meaning extremely low
downtime) and are currently in use to connect both Fire Stations 12 & 14 to the Village
network.
1
Staff is recommending the tower vendor
,, Critical Technologies, and to waive the bidding
requirements due to the complexity of the project related to both procuring and installing a
new tower,, along with wireless antenna setup. Critical Technologies has performed work for
the Village in the past and their work was performed satisfactorily. In addition, they have
performed work similar in scale and scope to this project for other customers. The project
timeline is also constrained; the EOC & Public Works wireless link needs to be completed
before this winter due to Block 56 redevelopment and its resulting demolition of the now -
vacant public safety building. The total cost of this project is not to exceed $55,951.50
(10% contingency included) and also has minimal ongoing maintenance, making it an ideal
solution to connect distanced facilities. The existing radio antennas on the existing tower
will be relocated to the new tower as part of this project.
The design of this structure offers an antenna life expectancy of 8-10 years and a tower life
expectancy of 20+ years. It was the Village's desire to install private underground fiber
lines connecting this building to the Village network. However, this project has a
significantly higher cost and lengthy timeline due to permitting through Illinois Department
of Transportation and Union Pacific Railroad due to the construction locations. This
antenna tower solution allows the Village to postpone private underground fiber installation
(and associated cost) to future years, without loss of connectivity.
