This is a Scope of Work document for the Illinois Department of Transportation (IDOT) involving the Illinois Tollway, detailing intersection improvements and roadway construction services for the I-90 Corridor Improvement Project in Cook County, Illinois. The project encompasses the design and construction of various intersection improvements, including new traffic signals, pavement reconstruction, drainage modifications, and utility relocations across multiple locations along the I-90 corridor. The scope includes detailed specifications for roadway rehabilitation, concrete and asphalt paving work, traffic control measures, and environmental compliance requirements. The contract requires the contractor to complete design phase activities, obtain necessary permits, and execute full construction of the defined improvements. The project timeline includes preliminary engineering phases, public coordination, and construction completion within specified timeframes established in the contract documents. Site conditions documentation, existing utility information, and traffic management plans are integral to project execution.

The contract is structured as a design-build or construction services engagement with payment based on unit prices and lump-sum line items for defined work scopes. The Illinois Tollway is the funding source for this project, with costs to be established through the formal bidding process. Contractors must demonstrate experience with roadway construction, traffic signal installation, and coordination with existing tollway operations. Environmental considerations including stormwater management, erosion control, and compliance with Illinois Department of Natural Resources requirements are mandatory elements. The work requires coordination with existing tollway traffic patterns and may necessitate temporary lane closures or traffic diversions during construction phases.
