Here’s an article on the stages of building inspections in Queensland, including the mandatory inspections:
The 5 Essential Stages of Building Inspections in Queensland
Building inspections are a critical part of the construction process in Queensland, ensuring that structures comply with the safety, health, amenity, and sustainability standards as outlined in legislation and building codes. This article provides an overview of the stages of building inspections and discusses the mandatory inspections required by law.
Understanding Building Certification
Building certification, commonly referred to as building inspection, involves an independent review of building work. A building certifier is responsible for checking and approving construction to confirm it meets the required standards. Upon satisfactory completion of a stage, the certifier issues a Form 16 – Inspection certificate1.
Mandatory Inspections for Class 1a and 10 Buildings
The Building Regulation 2021 mandates several inspections for new houses (single detached class 1a buildings) and class 10 buildings (like sheds and garages). These inspections are crucial to ensure compliance at various construction stages:
Excavation
- Before pouring concrete: The site must be inspected after the foundation material is excavated and before pouring the concrete for footings or slabs1.
Footings
- Pre-concrete pour: If the building has footings, an inspection is required after the placement of formwork and reinforcement but before pouring the concrete1.
Slab
- Pre-concrete pour: Similar to footings, the slab must be inspected after formwork and reinforcement placement and before the concrete is poured1.
Frame
- Structural integrity: The frame of the building is inspected to ensure it meets the breakdown of the framing stage under section 44 of the Building Regulation 20211.
Final
- Completion check: The final inspection covers a range of aspects, including site works, drainage, termite management, damp and weatherproofing, fire safety, and more1.
For class 10 buildings, the only mandatory inspection is the final stage, although additional inspections may be listed in the building approval1.
Inspections for Class 2 to 9 Buildings
While the Building Regulation 2021 specifies mandatory inspections for class 1a and 10 buildings, it does not set similar requirements for class 2 to 9 buildings, which include multi-storey residential buildings, office buildings, shops, public halls, and commercial and industrial buildings1.
Role of Building Certifiers
Building certifiers play a pivotal role in the inspection process. They are tasked with ensuring that the construction complies with approved plans and the Building Code of Australia (BCA). It is typically the building contractor’s responsibility to engage a private certifier on behalf of the client, but property owners can also appoint a certifier directly2.
Conclusion
The stages of building inspections in Queensland are designed to uphold the integrity of construction projects and ensure they meet all necessary standards. Mandatory inspections serve as checkpoints at critical phases of construction, providing peace of mind that a building is safe, secure, and compliant.

5 Stages Table
Here’s a table summarizing the essential stages of building inspections in Queensland:
Table
| Stage | Description | Mandatory Inspections for Class 1a and 10 Buildings |
|---|---|---|
| Excavation | Inspection after foundation material is excavated and before pouring concrete for footings or slabs. | Yes, before pouring concrete. |
| Footings | Inspection after placement of formwork and reinforcement but before pouring concrete. | Yes, pre-concrete pour. |
| Slab | Inspection after formwork and reinforcement placement and before the concrete is poured. | Yes, pre-concrete pour. |
| Frame | Inspection to ensure the structural integrity of the building frame. | Yes, structural integrity check. |
| Final | Comprehensive completion check covering various aspects of the construction. | Yes, completion check. |
For class 10 buildings, the only mandatory inspection is the final stage, although additional inspections may be listed in the building approval. Class 2 to 9 buildings do not have specified mandatory inspections under the Building Regulation 2021, but they must still comply with the Building Code of Australia (BCA) and are subject to inspections by building certifiers.
I hope this table provides a clear overview of the building inspection stages in Queensland.
