Infrastructure Development Code


The Consent Holder's Representative or the Engineer are responsible for ensuring that the formal inspections/tests are undertaken in accordance with the IDC. Council also undertakes random informal inspections during the course of the works.

Council attends these inspections/tests:

  1. As a co-stakeholder of infrastructure development with the emphasis on the construction of quality assets that will be vested in Council ownership and/or private assets that connect to and therefore have an effect on public assets.
  2. To ensure good industry practice that benefits all stakeholders, especially the general public and to ensure the quality, longevity and maintenance of the assets in the future.
