Standard Plans, Standard Specifications and Contract Item Codes

The use of the California Department of Transportation Standards is required to ensure that all transportation project contracts are clear, concise, correct, complete and in compliance with the Federal Highway Administration (FHWA). Substantial justification and approval for deviation from the Standards is required. Deviation should be rare and will not be approved for minor or preferential changes.

These Standards are the culmination of extensive development by the Department's most competent and proficient professionals. Concurrence has been obtained from stakeholders, including the Construction Division, Legal Division and FHWA. When applicable, concurrence has also been obtained from industry and other agencies.

Future Updates

The  2024 Standards will be updated at the midcycle posting (Revised Standard Plans,  SSPs Updates, and Bid Item updates) to be implemented on April 21, 2025.
