Plans Preparation Manual (PPM)

Plans Preparation Manual - U.S. Customary Units (English)

The Plans Preparation Manual (PPM) establishes uniform standards and procedures to be used when preparing right of way maps, preliminary exhibits, and the development of project plans. The PPM states and illustrates how Caltrans presents a project for bidding and construction. The PPM text portion describes what should be contained on each type of project plan sheet and explains the how and why of presenting this information.

The PPM Examples illustrate the design presentation standards on each type of project plan sheet and contain valuable informational/explanatory notes.

This manual and examples are only available on the Caltrans internet website and will be incrementally updated by section as needed to reflect current design presentation standards for all advertised projects on the State Highway System (SHS). Future updates to any section will supersede any section with an earlier date. All previous changes to the PPM are summarized in the PPM Errata.
