Critical Stage



What is a critical stage inspection?

Critical stage inspections are mandatory inspections that are required as part of your development consent..A Critical stage inspection ensures that what is being built is consistent with what has been designed and issued as construction drawings with the appropriate amendments.

Some examples of critical stage inspection include:

  • After excavation for, and prior to the placement of, any reinforcement for footings
  • Prior to pouring any in-situ reinforced concrete structural element with the placement of the appropriate steel reinforcement.
  • Prior to covering of the framework for any floor, roof, wall, or other structural element
  • Prior to covering any stormwater drainage connections
  • After building work has been completed and prior to any occupation certificate being issued

What to look out for

What is considered ‘critical’ stage also varies for different building classes. Check your development consent for the list of all critical stage inspections that are required to be performed.

Additionally, ensure that you inform your primary contractor about the critical stage inspections. If inconsistencies are found at these inspections by the structural engineer, written instructions are issued on site to the builder for appropriate rectification. This may include additional reinforcement to what has been specified to suit site conditions.
