All signing and delineation work shall be prepared in accordance with the NCDOT or PEF's quality assurance/quality control standards (QA/QC). The firm or agency that prepares the plans is responsible for the quality control process. Reviewing agencies or GECs are not responsible for QA/QC of the designer's product. Quality Control principle requirements for signing and delineation projects are as follows:
- The designer shall adhere to a documented QA/QC process. The NCDOT's QA/QC standard may be found here (Under Development).
- For signing design plans, the designer should use NCDOT's three person check (3PC) method for checking plans prior to all submittals. The 3PC method is described in Chapter 4.
- All QA/QC reviews should be performed by someone prequalified to do signing and pavement marking plans.
- Agency/GEC reviewers are responsible for review of general adherence to the project's scope, compliance with standards (MUTCD and NCDOT) and the Signing and Delineation Unit Procedure Manual. Guidance for reviewers may be found in Chapter 9.
