Roadway Weather Information System

The Illinois Department of Transportation (IDOT) is procuring a comprehensive Roadway Weather Information System (RWIS) maintenance and support services contract for 53 existing locations throughout the state, with potential expansion to 56-58 sites. The contract, identified as B-47475, will cover annual preventative maintenance, repair services, installation of new RWIS locations, communications system support, and database/web interface management. Key deliverables include 48-hour response times for repairs, completion of service within five working days, support for both Vaisala and Boschung brand equipment, and maintenance of up to 150 user database accounts. Vendors must provide technical capabilities for managing RPU video cameras, supporting modem communications, and ensuring 24/7 system availability with appropriate backup power and disaster recovery. The bid is due on August 6, 2025, at 1:00 PM, with questions accepted up to seven days from the bid opening. Evaluation will be based on responsibility, responsiveness, and lowest price, with the contract running through June 30, 2029, and a maximum total term not exceeding ten years.

The procurement does not appear to be specifically designated as a small business set-aside, though it does include a $15 Minority Contractor Opportunity Initiative fee. Vendors must comply with the Business Enterprise Program and Veterans Small Business Program Utilization Plans, and subcontracting is explicitly prohibited for this procurement. The current system involves equipment from manufacturers including Vaisala, HMP155, RM Young, and Digi, deployed across nine IDOT districts with strategic positioning at critical infrastructure points. While specific budget ranges are not explicitly detailed, the contract includes pricing structures for annual preventative maintenance, service calls, parts replacement, and monthly database/web interface services. Vendors must be prepared to support existing infrastructure, potentially add 3-5 new RWIS sites during the contract term, and provide comprehensive reporting including weekly data quality reports and maintenance of historical sensor data for a minimum of five years.
