The purpose of this Request for Proposal (RFP) is to solicit sealed proposals from firms to collect Condition Rating Survey (CRS) data used to assess the pavement condition of Illinois’ nearly 16,000 center line mile highway system, Illinois’ portion of the National Highway System (NHS) and other highway systems throughout Illinois. The CRS is an important tool to assist the Department and other Highway Authorities with pavement management systems and preservation, rehabilitation, and reconstruction decisions.  The CRS contributes to the decisions by providing an overall assessment of the pavement condition and performance of the highway systems. It is the basis used to determine current pavement condition, project future pavement conditions, and predicting future programming needs and treatments. The collection must provide high quality pavement data for the required reporting of highway condition and national pavement performance measures to the Federal Highway Authority (FHWA). Additionally, there is an increased need for identification and inventory of specific highway roadside assets, their attributes, and safety components used in making highway asset management decisions.  The goal is to ensure the collection of high quality and valid geo-referenced highway pavement condition and highway asset inventory data statewide for analysis and reporting.
