The solicitation numbered 26-557THA-ENGCO-B-51413, issued by the Illinois Tollway Construction office in Downers Grove, IL, seeks professional on-call design and construction engineering services primarily for transportation infrastructure projects like the Elgin O’Hare Western Access (I-490). The contract covers Phase II and Phase III engineering services, as well as construction corridor and management support, including quality assurance, material testing, traffic management, utility coordination, and regulatory compliance. Services must adhere to state and industry standards such as IDOT training programs, the AASHTO Accreditation Program, and Illinois Tollway’s Standard Business Terms and Conditions. Personnel requirements include licensing mandates for engineers and specialized certifications for QC/QA and construction documentation staff. The contract enforces organizational independence between quality assurance and design teams and mandates submission and approval of a Consultant Quality Program (CQP) within 14 days after the Notice to Proceed. Proposals are evaluated on a qualitative and holistic basis emphasizing specialized and technical experience, past performance, innovative cost-saving approaches, schedule feasibility, key personnel availability, proposed methodology, and compliance with DBE/VOSB participation goals. The contract expressly avoids a Lowest Price Technically Acceptable (LPTA) award process, favoring a trade-off methodology to select the proposal best suited to the Illinois Tollway’s interests. There are no stated formal options for renewal or extensions, and no line-item pricing is provided, though upper compensation limits exist under certain blanket agreements. Strict conflict of interest disclosures and mitigation procedures are required, including restrictions on concurrent services and mandatory reporting of changes in affiliations. Submissions must follow a detailed proposal format with specific exhibits and certifications addressing socioeconomic participation and other compliance matters, all submitted electronically in PDF format by a fixed deadline in March 2026. The contract administration framework includes contact points for contractual oversight but lacks detailed payment or invoicing instructions. Performance is expected over approximately five years from an anticipated Notice to Proceed in August 2026, with the place of performance designated as Downers Grove, Illinois.
