What occurs during the preliminary/final-design phases?
The detailed engineering necessary to advance the project to construction is completed during the final-design phase. Project team members will be visible in the project area as final-design activities are conducted. Building upon the work completed in the preliminary-engineering phase, the project team will continue to refine plans, impacts and mitigation components of the project. Right-of-way needs will be determined. Extensive coordination efforts with utilities, regulatory agencies, environmental agencies, municipalities and emergency-service providers will take place throughout this phase. This coordination is essential to minimizing disruption of services during construction. Safety features – such as signing and lighting – will be incorporated into the plans and necessary permits obtained. The final-design phase will result in the development of the plans, specifications and estimates from which construction contractors will ultimately build the roadway.
