Hierarchy Review & Redefinition


A network hierarchy forms the basis of an authority’s asset management practices, governing everything from inspection frequencies to works programmes. Metis have been involved in updating network hierarchies for various authorities, aligning these with a risk-based approach as required under the Code of Practice (2016).


  • Worked with Council officers to understand the existing hierarchy and establish a new risk-based ruleset, considering functionality and usage
  • A GIS exercise to understand the location of key traffic generators on the authority’s network
  • Refresh the highway hierarchy based on the new ruleset
  • Assess and agree on inspection frequencies against each hierarchy, based on risk
  • Compare hierarchy and inspection frequencies with neighbouring authorities to ensure a consistent approach across boundaries
  • Evaluate resource implication and advise on the best way forward


Through this project, each authority has:

  • Updated its network hierarchy and inspection frequencies in line with a risk-based approach as required under the Code
  • Strengthened their Section 58 defence against compensation claims
  • Established hierarchy regimes that focus resources on the areas of highest risk to the Council
  • A fully auditable trail which can be used in preparing a court defence
