Design Exceptions

Design Exception FormThe design exception process is intended to ensure that sound engineering decisions are made when design options are limited.

Exceptions to design standards should be discussed early in the design process when project limits are first determined. All design exception requests must show justification.

Digital Signatures

For design exceptions, we only use digital signatures. While ink signatures are legally valid, this type of signature is more secure and helps us store these important documents electronically.

Using digital signatures on design exception requests.

Be sure to follow the procedures noted below to avoid unwanted delays.

Digital Seals - Refer to TSB21-01(D), Digital Seal and Signature Requirements for Engineers and Land Surveyors.

Applying for a Design Exception

Please note: Applying for an exception does not guarantee approval. Exceptions must be submitted at or before the Design Acceptance Package milestone.

Notify us if the design team determines a design exception is no longer needed.

Unresolved design exceptions in the database may impact your contract advertisement.

Application Process

  1. Obtain a control number.
  2. Request a control number by emailing the Design Exceptions Team. The state traffic roadway engineer is the approving engineer. When the approving engineer is unavailable, an interim authority will be assigned. The design exception administrator will provide the seal.

  3. Create a draft design exception request form.
  4. Add the control number to the top of the form and the approving state traffic roadway engineer seal at the bottom of the form.

  5. Submit a draft.
  6. Roadway subject matter experts, based in the Statewide Project Delivery Branch, will review your draft design exception request.

  7. Finalize the form.
  8. Incorporate any necessary details or changes.

  9. Apply the digital signature fields to the form.
  10. This includes the engineer of record, appropriate project and region representatives, and the approving engineer.

  11. Route for signatures.
  12. Collect digital signatures from region technical center representatives.

  13. Submit the form.
  14. Send your completed form or the ProjectWise link to the design exception administrator for final review by the approving engineer.

  15. Save it.
  16. Save a copy of the form in the corresponding project file. Use ProjectWise when available and follow ODOT naming conventions.

  17. Review approved request.
  18. Once approved, you will receive an email with a link to the approved design exception.

Additional information about this process is included in Part 1000​ of the Highway Design Manual.

Application Process

  1. Create a draft design exception request form.
  2. Send the draft form (MS Word version) to the designated reviewers at the Statewide Project Delivery Branch. Save a copy of the draft form in the project file. Use ProjectWise when available and follow ODOT naming conventions.

  3. Finalize the form.
  4. Incorporate any necessary details or changes. Insert information into the most current version of the ADA curb ramp design exception​ from the web.

  5. Apply the engineer of record seal and sign the form digitally.
  6. Digital signature fields are already in the PDF form.

  7. Route for signatures.
  8. Representatives from the appropriate region technical center must review and digitally sign the form.

    Once signed, each reviewer must save and finalize his or her section of the form. Reviewers must adhere to standard ODOT naming conventions during this step.

  9. Send the signature confirmation email.
  10. As each reviewer finalizes the file, an email is auto-generated. This email must be sent to the signature authority; we recommend including the engineer of record as a courtesy copy recipient.

  11. Send it to the Roadway Unit.
  12. Send the form to ODOT Design Exceptions once all region technical center reviews are complete and signatures applied.

    The design exception administrator will assign a control number and route the form to the state traffic roadway engineer for review. An email with a link to the final design exception will be sent when approved.

  13. Save it.
  14. Save a copy of the form in the corresponding project file. Use ProjectWise when available and follow ODOT naming conventions.

  15. Review approved request.
  16. You will receive an email indicating whether you request was approved or rejected. If approved, the email will include a link to the approved design exception.
