Phase I Engineering

Service Overview

Broad Scope

CBBEL provides Preliminary Engineering and Environmental Studies (Phase I Engineering) to municipalities, counties and government agencies like the Illinois Department of Transportation and the Illinois Tollway for projects ranging from intersection improvements and bike path projects to highly complex roadway realignment and new expressway projects.

Detailed Study

Phase I Engineering studies are multi-disciplinary efforts that frequently require the completion of detailed studies on traffic performance; safety; noise; socio-economic and environmental impacts; structural design; drainage improvements; and roadway/bike path design and alternatives analysis. Additional considerations include public/stakeholder involvement and coordinating with state, federal and resource agencies to secure all required approvals before subsequent phases of project development can proceed. CBBEL staff is prequalified by IDOT for public involvement and has expertise within each of these discipline areas and a proven track record of completing all required discipline studies to accomplish the overall established Phase I project schedule.

Proven Track Record

A well-crafted and successfully implemented stakeholder involvement program ensures important and meaningful public input as part of key project development milestones and confirms a context-sensitive project design. CBBEL has in-house expertise and a proven track record for successfully implementing Context Sensitive Solutions (CSS) public involvement best practices on projects and is used by IDOT to assist other engineering firms with implementing CSS procedures.
