Consider the Project Development Process Manual as a guide:

  • The manual details almost 200 tasks, or major steps, involved in developing a transportation project from identifying the project need to construction letting.
  • Each task is described in a task summary. The task summaries form the majority of the manual’s text. Tasks are grouped together into “sections” and “subsections.”
  • For the manual to cover many project types and complexity levels, almost every potential task is included. Use judgment in determining which task applies to a specific project.
  • Each task summary refers to a responsible party and may also describe critical sequencing. Use judgment with this information since projects may have unique staffing and sequencing requirements.
  • Many topics covered cannot be completely described. Use reference materials as appropriate.

Organization of Information

The project development process is broken into six chapters:

  1. Planning and Programming
  2. Preliminary Design
  3. Environmental
  4. Right of way and Utilities
  5. PS&E Development
  6. Letting

To associate tasks into groups and show sequencing between task groups, the following organizational system is used:

  • Chapter. Example: PS&E Development
  • Section. Example: Begin detailed design
  • Subsection (optional). Example: Traffic control
  • Task. Example: Plan sequence of construction

Table of Contents Links - Task summaries may be accessed directly through task summary titles listed in the table of contents of the Project Development Process Manual – the titles listed are online links to task summaries.

Links to text within this manual - Each section summary lists titles of task summaries. These titles are online links to only task summaries within this manual. Task summaries contain links to related information within the Project Development Process Manual.

Links to text in other manuals - Task summaries also contain links to related information in other TxDOT online manuals and the TxDOT Glossary. The summaries also give references and links to resource material by TxDOT and others.

Flow Chart

A flow chart of the entire project development process can be downloaded in MicroSoft→ Excel format for printing or plotting.

The flow chart shows six rows of the chapters arranged relative to a time line. Each chapter row contains a sequence of sections and subsections.


The Project Development Process Manual:

  • is a technical manual that covers the “who”, “what”, and “when” of the project development process.
  • provides references and online links to the procedural (“how to”) information contained in TxDOT procedures manuals.
  • is written primarily for TxDOT personnel.
  • describes “tasks” or steps involved in developing a transportation construction project - from inception to letting.
  • provides very basic information on a broad range of topics, written in a simple manner, for users with varying experience levels and specialty areas.

The Project Development Process Manual should:

  • help prevent project delays by clearly showing the sequence of project tasks.
  • enable project staff to perform a task only once and at the right time.
  • give experienced project managers a quick reminder list of tasks.
  • reduce learning time for employees assuming new responsibilities.
  • improve communication and understanding between TxDOT districts, divisions, and the consultant community, by providing a clear and consistent definition of the process and its component tasks.
  • make it easier to prepare project schedules and scopes by offering defined work items, terminology, and sequencing.
  • promote overall understanding between staff, often working in specialized areas, on how their work relates to work by others.
  • give an appreciation for each other’s diverse work responsibilities.
  • enable improving the process by documenting its current arrangement.
