Work out structural audit cost instantly with clear inputs, formula shown and shareable results.
A structural audit combines visual inspection charged by area with non-destructive testing priced as a lump sum: rebound hammer, ultrasonic pulse velocity, cover meter, carbonation and chloride sampling. The certification report is charged as a percentage of the field work. Audits are mandatory at defined building ages in many jurisdictions.
Audit cost
Total = (area x audit rate + testing lump sum) x (1 + report fee percentage)
Preliminary estimate only. Structural audits must be carried out by a licensed structural engineer to the scope prescribed by the local authority.
Total = (area x audit rate + testing lump sum) x (1 + report fee percentage). A structural audit combines visual inspection charged by area with non-destructive testing priced as a lump sum: rebound hammer, ultrasonic pulse velocity, cover meter, carbonation and chloride sampling.
Commonly at fifteen and thirty years of building age, and then at shorter intervals, but the trigger varies. It is also prudent before purchase of an older building or after any structural distress.
