Who We Are

CBBEL is a multidisciplinary consulting engineering firm designed to support complex infrastructure projects from start to finish. Our team of more than 260 professionals serves public and private sector clients throughout Illinois, including municipalities, counties, townships, utilities, and private developers.

What differentiates CBBEL is our depth of in-house expertise. Rather than outsourcing key disciplines, we integrate civil design, water resources, environmental services, traffic operations, urban planning, structural engineering, surveying, construction engineering, and more within a single team.

Our staff includes three PhDs, more than 100 licensed professional engineers, 22 Certified Floodplain Managers, 11 Certified Professionals in Erosion and Sediment Control, and nine Certified Professionals in Stormwater Quality, as well as professional traffic operations engineers, Board Certified Water Resources Engineers, licensed professional land surveyors, licensed structural engineers, American Institute Certified Planners, and a licensed landscape architect.

The Work We Do

Planning Through Construction

CBBEL supports infrastructure projects at every stage, from early planning and feasibility studies through design, permitting, and construction.

Over four decades, we have built long-term relationships with clients across Illinois by delivering practical, well-coordinated solutions to complex engineering challenges.

Deep Project and Service Experience

We have served as lead engineer on a wide range of municipal and county projects, including roadway and transportation improvements, bike and pedestrian facilities, bridges, pump stations, stormwater systems, and water infrastructure.

CBBEL also provides professional reviews, grant assistance, GIS services, environmental assessments, and regulatory support to support informed decision-making and effective project delivery.

Permitting, Funding, and Agency Coordination

CBBEL helps clients navigate regulatory and funding requirements with confidence. Our teams have obtained thousands of permits from the U.S. Army Corps of Engineers, the Illinois Department of Natural Resources, and FEMA, and are prequalified by the Illinois Department of Transportation for public involvement.

This experience helps projects move efficiently through review, approval, and reporting processes.
