911 Tower Inspection HK

The Illinois State Police is soliciting a contract for 911 tower inspections across Illinois, with proposals due June 16, 2026. The procurement covers approximately 80 communication towers managed by ISP and three other state agencies (Illinois Department of Transportation, Illinois Department of Natural Resources, and Illinois Department of Corrections) serving 911 dispatch and emergency response operations.

Inspectors must conduct detailed structural, safety, and operational assessments of tower facilities using the ANSI/TIA-222-H maintenance and condition assessment checklist. Inspection scope includes evaluation of structural integrity, finish condition (paint and galvanization), lighting systems (incandescent, strobe, and beacon configurations), grounding, antennas, platforms, insulators, guy wires, concrete foundations, and overall tower alignment. Inspectors must document guy-wire tension, temperature and wind speed conditions, and FAA/ICAO color-marking compliance. Most towers in the inventory are Rohn-manufactured guyed-style structures ranging from 60 to 960 feet in height, with construction dates from 1975 to 2007. Tower locations span multiple Illinois regions and are geographically indexed with latitude and longitude coordinates provided in the detailed tower inventory.

The tower list identifies inspection scheduling for 2025 through 2027, with the majority of work in 2026 and 2027. RF resources in use include S21, ISPERN, HF2, IREACH, HF4, and Point Microwave systems across various tower locations. Proposals must address the full Illinois Standard Terms and Conditions document for State of Illinois procurement, which governs payment, insurance, indemnification, compliance, and contract administration procedures. No contract value, contract term length, incumbent contractor, evaluation criteria, or pre-bid meeting date is identified in the available materials.
