Specifications and Photos - Polk Co.pdf

This specifications document pertains to communication tower removal services for Polk County Department of Transportation in Iowa. The tower is located at the DOT garage in Grimes, Iowa (2310 SE 17th Street, coordinates 41° 40' 32.8" N, 93° 46' 4.5" W) and is a 180-foot tall Rohn tower originally installed in 2002 (F number F00351A). The tower requires removal and is equipped with top and side-mounted DB224 antenna sets with associated cabling and a 12-inch dish antenna positioned at 50-75 feet. The removal presents logistical constraints as the tower is landlocked and positioned directly adjacent to the main garage, necessitating that removal equipment be staged in the employee parking lot. A crane and specialized tower crew will be required for the removal operation.

No original tower drawings or construction documentation are available for this structure, and the weight of individual sections and total tower weight cannot be verified. The specifications document notes that the provided description is for reference purposes only and is not a guarantee of the actual tower configuration. The proposal due date for this procurement is August 27, 2026, with posting date of August 6, 2026.
