Planned Construction

Project Engineering Phases

In order for the McHenry County Division of Transportation to start any project, we must follow a multi step plan established by IDOT. The plan takes a project from conception till completion and can vary in the length of time each step takes. There are of course exceptions in extreme situations, but generally this plan ensures a more efficient and safe roadway for the public.

The Steps are as follows:

Planning
Transportation Projects typically originate from an adopted Long Range Transportation Plan and are carried into the County’s 5-Year Transportation Program.

Preliminary Engineering/Phase I

An engineering report involving a project’s geometric design, right-of-way requirements, alternatives analysis, and environmental studies.

Design Engineering/Phase II

Translates the Phase I engineering report into contract plans, specifications and cost estimates for land acquisition and construction as well as the execution of local-state joint project agreements.

Construction/Phase III

The project enters the construction phase, which includes associated construction engineering activities such as surveys, staking, inspections, materials testing, checking shop drawings, supervision of contractors, field adjustments and plan revisions, record keeping, and documentation, and payments to contractors.
