I-25-4768 - EWO #3 - ATP #3 - I-490 Grading and Drainage Improvements

This procurement opportunity, solicitation number 27-557THA-ENGCO-B-53913, concerns grading and drainage improvements for I-490, under ATP #3 and EWO #3. The contracting authority is the Toll Highway Authority (THA) in Illinois, United States. This project focuses on essential site preparation and water management for the I-490 corridor. The scope of work will likely involve extensive earthmoving operations, including excavation, grading, and embankment construction, to establish the correct road profile. Crucially, it also includes the design and implementation of a comprehensive drainage system to manage stormwater runoff, prevent erosion, and ensure the long-term stability of the roadway. Bidders will need to demonstrate significant experience in heavy civil construction, particularly in large-scale grading and complex drainage system installation. Requirements will include adherence to engineering plans, environmental regulations, and robust site safety protocols. The ability to manage large volumes of earthwork efficiently and install effective drainage infrastructure, such as culverts, ditches, and storm sewers, will be paramount. The THA seeks contractors capable of delivering these foundational improvements to the required standards and timelines.
