Detail Design Phase

During the detail design phase, various design elements are finalized and construction plans are developed. Project development in this phase can include many intermediate reviews prior to final plan submission. These may include some or all of the follow­ing, depending on the complexity of the plan:

Traffic request/validation Traffic signal warrant analysis Airway-highway clearance study Alignment, grade, and typical section review Conceptual maintenance of traffic review Structure type study Retaining wall justification Service road justification Preliminary drainage review Preliminary right-of-way review Bridge type, size, and location study Drive review

This is not intended to be an all-inclusive list. The designer should contact the government agency having review and final acceptance authority to see what reviews are required during this phase of plan development.

Following acceptance of the final plans, specifications, and estimates, the project is processed for letting. Any necessary consent legislation is obtained. The project is then advertised, bids are taken, and the construction contract is awarded.
