How to win design work with the Illinois DOT
Keep your firm's prequalification current. Illinois DOT says prequalification is mandatory for firms seeking construction, engineering, land surveying, or architecture work, and it posts updated directories of prequalified firms. Check the DOT's prequalification and registration page for the requirements and directory links. Illinois DOT advertises professional services, construction, and specialized material opportunities continually. Review its procurement pages and the Professional Transportation Bulletin regularly so you can identify work that fits your team.
For federally funded architecture and engineering work, federal law requires qualifications-based selection under the Brooks Act. Build a clear record of your firm's relevant experience, staff qualifications, and approach. Confirm current requirements on the DOT site before preparing a proposal.
