The purpose of this manual and the definitions used within are intended to describe the general project development process and associated activities, milestones and key tasks for the development of transportation construction projects at TxDOT. Not all activities will be applicable to all project types. The level of project development will depend on a project’s rigor as discussed in and the project’s specific needs and requirements.

It is important for the engineering practitioner to understand the full project development process, including which activities can be performed under the specific project authorization levels (i.e.,

PLAN, Develop, Construct

– see ). This guidance presents tools, references, training, and the needed level of coordination for the respective project activities.

This guidance is not intended as a financial or forecasting tool for programming, planning, financing, and portfolio management. Business, finance, and planning processes are distinct with unique terminology and definitions. More information is available through other Division offices (i.e., Transportation Planning and Programming Division (TPP), Financial Management Division (FIN), and Transportation Programs Division (TPD).
