In October 2016, the NRA Project Appraisal Guidelines were superseded by the TII Project Appraisal Guidelines for National Roads. The updated guidelines cover a variety of issues including:

  • Update to governance as set out in the Public Spending Code including level of appraisal at different spending thresholds
  • Update to the parameters required for project appraisal as set out by Public Spending Code and Common Appraisal Framework e.g. discount rates, value of time
  • Updated tools and guidance on their use to improve the capturing of benefits on schemes e.g. TUBA, COBALT
  • Standard appraisal tools for Minor Projects to ensure proportionality of appraisal (PE-PAG-02035(Minor Projects €5m - €20m) and PE-PAG-02037 (Minor Projects €0.5m - €5m))
  • Take cognisance of user feedback and experience gained from undertaking audits of appraisal documents to provided targeted guidance on specific issues e.g. Multi-Criteria Analysis, Model Calibration & Validation Thresholds
  • Linking with update to Project Management Guidelines and associated phases
  • Guidance on Motorway Service Areas
