The Gwinnett County Board of Commissioners is soliciting competitive sealed proposals from qualified consultants to provide Transportation Consultant Demand Professional Services on a Multi-Year Contract for the Department of Transportation. This solicitation will assist GCDOT in selecting firms to provide demand service support for GCDOT in its implementation of its Special Purpose Local Option Sales Tax (SPLOST) and other capital programs. No minimum or maximum amount of work is guaranteed under this solicitation, and work will be procured on an "as-needed" basis. Firms must be pre-qualified in the appropriate Georgia Department of Transportation (GDOT) Area-Class for each category sought and must provide current GDOT Notice of Professional Consultant Qualification for each category proposed. Gwinnett County intends to select a minimum of three (3) firms under each of the Service Categories and reserves the right to award to a smaller or larger number of firms.
Service Categories (each requires a separate proposal and separate fee schedule):
• Service Category A – Pedestrian/Bikeway and Roadway Drainage Improvement Design Services
• Service Category B – Major Roads, Minor Roads, and Intersection Improvement Design Services
• Service Category C – Cost to Cure

The selected consultants will be required to sign a Demand Services Contract for Professional Services and meet the insurance requirements specified in the solicitation (including professional liability, commercial general liability, automobile liability, workers' compensation, umbrella/excess, and other coverages as applicable). The contract term contemplates commencement on July 1, 2027 or upon award, with the first year expiring December 31, 2027, and may be in effect for up to five years.
