Professional Services Bulletin (PSB), Solicitation and Pre-Award
The Illinois Tollway procures professional engineering and consulting services through a Qualifications-Based Selection (QBS) process governed by the Architectural, Engineering, and Land Surveying Qualifications Based Selection Act.
Opportunities are announced in a Professional Services Bulletin (PSB), which details project scopes, schedules, and requirements for Statements of Interest (SOIs). Interested firms submit SOIs outlining qualifications, experience, and proposed team composition.
The Tollway evaluates submissions based on published criteria such as technical expertise, past performance, and capacity to deliver. Pre-award activities include verification of disclosures, compliance with DBE/VOSB participation goals, and negotiation of scope and fees.
All awards are contingent upon successful negotiations and Illinois Tollway Board approval.
Construction Solicitation and Pre-Award
The Illinois Tollway’s construction solicitation and pre-award processes are structured to ensure transparency, competitiveness, and compliance with state procurement laws while advancing major infrastructure programs.
During the solicitation phase, projects are publicly advertised in BidBuy and contractors access bid documents through the Tollway’s Online Plan Room. Pre-bid activities, such as Q&A sessions and addenda, clarify requirements before submission.
In the pre-award phase, bids are evaluated for responsiveness and compliance, vendor qualifications are verified, and diversity and veteran participation goals are confirmed.
All awards are contingent upon Illinois Tollway Board approval.
