Feasibility/Concept audits are conducted at an early stage when preliminary design plans may or may not have yet been generated. At this stage the advantages and disadvantages of major elements such as alignments and intersection types are assessed against each other from a safety perspective.

Feasibility/Concept audits are normally conducted for medium to large projects only, but can be of benefit to smaller projects depending on the nature of the works.

Why audit at the Feasibility/Concept stage?

  • There is greatest scope for change at this stage
  • Avoids problems that cannot be avoided at a later stage
  • Ensure all road users have been considered in the design
  • To check that the project fits into the overall environment suitably or whether additional works will be required
