Project Development Phases

VTrans project development phases are prescribed by State Highway Law and by internal policies and practices. Typically, VTrans projects follow the following steps.


Project scoping is the process of developing and evaluating alternatives and selecting the most appropriate alternative for the conceptual design phase.

Conceptual Design

The Conceptual Design phase includes the advancement of concept plans that were developed during scoping and the quantitative analysis of environmental impacts of the selected alternative.

Preliminary Design

The preliminary design phase includes the development of preliminary plans and construction costs for the selected alternative as well as obtaining environmental permits.

Final Design

The final design phase includes development of most of the structural design, traffic signal, and landscaping details; acquisition of land and/or rights; development and execution of utility or railroad agreements; and preparation of special provisions.


The construction phase involves the transfer of contract plans and documents to the Resident Engineer and the construction process.
