APPENDIX G
Caltrans WBS

The following is an excerpt from the Caltrans Guide to Project Delivery Workplan Standards that illustrates the work packages at the lowest level of the WBS.¹ Note that this is not a complete listing of work packages and WBS codes and should not be used on a specific project. The appendix does illustrate, however, how one organization uses a complete WBS template and detailed definitions to assist in managing its programs.

WBS 160 PERFORM PRELIMINARY ENGINEERING STUDIES AND DRAFT PROJECT REPORT

Work involved in conducting preliminary engineering studies used in the development of a draft Project Report (PR) and a final Environmental Study Request (ESR). Work may include survey work and preliminary field studies directly related to the PR and ESR. Support from Environmental units is also covered.

Note: For projects not requiring a Draft Environmental Document, the final product of this activity is actually the Project Report.

160.05 Updated Project Information

This activity includes review of the information assembled and developed during the PID, as well as a preliminary assessment of what additional information may be required during the project report and environmental document development.

End Product:

Understanding of project need and purpose, scope, cost and what additional studies may be required during the Project Report development.

160.05.99 Other Updated Project Information Products

All other work, during the Updated Project Information efforts, not defined or covered in other 160.05 elements.

160.10 Engineering Studies

This activity includes developing in more detail or updating those studies initiated during the PID. It also includes those additional engineering studies required to address new alternatives or revisions developed during the environmental process.

End product:

Refinement of project alternatives, and further design of all project features adequate for detailed discussion of project impacts in the environmental document and suitable for the initiation of final design.

160.10.10 Traffic Forecasts/Modeling

Includes all activities necessary to update and expand any previously completed travel forecast effort under WBS 150.05.25. Analyze travel-demand model data using Regional Transportation Planning Agencies (RTPA) traffic models when available. Prepare future traffic projections for intersections, highway mainlines and ramps for project level documents. Prepare traffic indices and design designations such as traffic index and equivalent single-axle load.

Evaluate the level of service that will result from alternative improvements to a facility. Includes all activities necessary to update and expand any previously completed traffic capacity analysis (WBS 150.15.45). Includes the use of macroscopic and/or microsimulation modeling, as appropriate, to perform traffic capacity/operational analysis on existing and future year project-specific needs for State highways. Includes integrating, ramp metering, HOV lanes and intelligent transportation system needs The operational impacts of various improvements are estimated and compared as a basis for decisions making and evaluation of proposed alternatives.
