Detailed engineering inspections

Detailed engineering inspections are carried out with the purpose of assessing the capacity of a structure, identifying and quantifying the current and projected deterioration of the structure, and to recommend appropriate management options.

We have developed a systematic approach to the investigations which includes:

  • Scoping the investigation with the client to ensure the investigation provides the appropriate outcome.
  • Undertaking a detailed visual inspection of the structure
  • Appropriate diagnostic testing including:
    – Covermeter surveys
    – Delamination surveys
    – Concrete resistivity
    – Half cell potential
    – Schmidt hammer
    – Carbonation testing
    – Magnetic particle testing
    – Die penetrant testing
    – Lead paint assessment
  • Undertaking laboratory testing on specimens including:
    – Cement content
    – Chloride concentration
    – Compressive strength
  • Load assessment in the as-new and as-is condition for
  • prescribed vehicles
  • Provision of a comprehensive written report including future management recommendations.

Level 2 inspections

Level 2 inspections are comprehensive visual inspections. Depending on the risk profile of the structure, inspections are carried out on a frequency of between 6 months and two years, and up to 6 years for small culverts.

The purpose of this level of inspection is to rate the condition of a structure as a basis for assessing the effectiveness of past treatments, identifying current maintenance needs, modelling and forecasting future changes in condition and estimating future budget requirements.
