Substandard workmanship and hidden defects can turn owning a new home into a nightmare. That’s why staged inspections are more crucial than ever – they’re your safety net against costly surprises and potential heartbreak.
Staged inspections ensure that at various construction phases, work complies with building codes, design specifications, and contractual agreements. Each inspection provides a snapshot of the construction progress, highlighting any areas that need attention and verifying that the build meets the expected quality and safety standards. Homebuyers and builders alike benefit from the transparency and accountability that these inspections provide.
During the construction process, several stages require thorough inspection. These typically include the slab stage, first fix frame stage, lock-up stage, internal linings, water proofing, fixing stage, and final handover stage. Inspectors assess the integrity and compliance of structural elements, the correctness of installations, waterproofing, insulation, and the overall workmanship quality. Such scrutiny protects the homeowner’s investment and helps prevent costly repairs or safety issues in the future.
Engaging a qualified building inspector is essential for a comprehensive evaluation of each stage of construction. These professionals possess the expertise to identify issues that may be overlooked by the untrained eye. They provide detailed reports that are valuable for both builders seeking to uphold their reputations for quality and homebuyers striving to ensure their new home is safe and sound.

Overview of Staged Inspections
Staged inspections are critical quality assurance checkpoints in the construction of new homes, ensuring that each phase of building meets designated standards before moving to the next stage.
Purpose of Staged Inspections
Staged inspections aim to verify that construction works adhere to Australian Building Codes and Standards at predefined stages. They are conducted by experienced inspectors who assess key elements like structural integrity, workmanship, and compliance with approved plans. By identifying issues early, they enable rectification before construction progresses too far, which can save time and prevent costly rework.
Benefits of Staged Inspections
- Risk Reduction: Early detection of potential problems reduces the risk of future structural failures and associated liabilities.
- Quality Assurance: Ensures the finished home meets industry quality benchmarks, providing peace of mind to homeowners.
- Regulatory Compliance: Confirms that the building process complies with all relevant regulations, reducing the likelihood of delays or legal complications.
- Financial Control: By minimising defects and ensuing disputes, staged inspections can contribute to keeping the project within budget.
Foundation Stage
Pre-Concrete Footing Inspection
The pre-concrete footing inspection is a crucial step that takes place before the concrete is poured into the footings of a building. During this inspection, the building inspector assesses various aspects of the site preparation and foundation work, including:
- Verifying the site is correctly positioned according to the approved plans
- Checking trenches dug for footings are of appropriate size and depth
- Checking proper installation of the Fortecon membrane which is crucial to protect the building from rising damp, which can lead to mould growth, structural damage, and health issues
- Examining the installation of electrical and plumbing services running through the footings, ensuring they are properly positioned and secured
- Inspecting steel reinforcement in the footings for correct size, type, configuration, and proper tying and support
- Checking termite barriers are installed correctly to protect the building from future infestations
Once all these elements have been assessed and approved, the concrete can be poured into the footings, and the building process can move on to the next stage.
Post-Concrete Footing Inspection
The Post-Concrete Footing Inspection is a vital step that occurs after the concrete has been poured into the footings of a building. During this inspection, the building inspector assesses the quality and accuracy of the completed footing work, focusing on the following aspects:
- Measuring footing dimensions to ensure they match the approved plans and are level and square
- Checking finished floor levels are at the correct height for proper drainage and accessibility
- Examining the concrete finish for smoothness, defects, and proper curing
- Measuring the size and depth of rebates or set-downs in the footings, which accommodate floor finishes or structural elements
- Identifying any issues, such as incorrect dimensions or poor concrete finish, that the builder must rectify before proceeding to the next stage
Once the post-concrete footing inspection is complete and all necessary corrections have been made, the building process can move forward with confidence that the foundation work has been executed to the required standards.
Structural Integrity Stage
A Structural Integrity Stage inspection is a critical assessment conducted by a qualified staged building inspector to verify that the load-bearing elements of a building, such as the foundation, walls, roof, and framing, are constructed according to the approved plans and meet the required safety standards and regulations.
Wall / Roof Framing Inspection
This stage involves constructing the skeleton of the building, including the walls, roof trusses, and any load-bearing structures. The inspector will assess the quality of the framing and ensure that it is sturdy, properly aligned, and meets all relevant building codes.
Material Quality: Inspectors check for the quality and compliance of the framing lumber. They ensure all timber meets Australian standards, checking for:
- Correct Dimensions: Timber must be of the right size and thickness.
- No Defects: Timber should be free from significant knots, splits, or warping.
Connection Points: They examine joints and fasteners, assessing the security of:
- Nails and Screws: Appropriate size and spacing.
- Brackets and Straps: Placement and anchorage for seismic and wind resistance.
Roof Covering and External Walls Inspection
At this phase, the external walls must be fully erected and cladded. One can expect to see:
- Materials: Use of brick, weatherboard, or other specified cladding materials.
- Insulation: Installation of insulation batts should be checked for compliance with Australian standards.
The inspector will assess the quality of the roof covering and ensure that it is properly sealed and secured. They will also re-assess the framing to ensure that it has not been compromised during the construction of the external walls.
Weatherproofing Inspection
An inspection is done to verify that waterproofing is applied correctly where necessary, for instance:
- Damp-proof Courses: Proper placement in walls to prevent moisture ingress.
- Sarking: Installation under roofing materials for additional protection against moisture.
Sealing Openings: They check windows and doors for:
- Correct Installation: Frames should be square and properly sealed.
- Flashings: Properly installed to prevent water penetration.
The Lock-Up Stage
The lock-up stage is a significant milestone in the construction process. It refers to the point at which the building is considered secure and weather-tight, with all external doors, windows, and roof coverings installed. At this stage, the building is essentially “locked up” and protected from the elements.
The lock-up stage typically occurs after the completion of the following tasks:
- Installation of the roof covering, including tiles, or metal sheeting.
- Installation of all external doors and windows, including frames, glass, and hardware.
- Completion of external cladding, such as brickwork, rendering, or weatherboarding.
- Installation of any necessary flashings and seals around openings to prevent water infiltration.
Once the lock-up stage is reached, the building is considered structurally complete and secure. This allows for the commencement of internal works, such as the installation of plasterboard, insulation, and utilities (electrical, plumbing, and HVAC systems).
Reaching the lock-up stage is essential for several reasons:
- It protects the building from weather damage, ensuring that internal works can proceed without the risk of water damage or other issues.
- It provides a level of security, preventing unauthorised access to the building site.
- It marks a significant progress point in the construction timeline, allowing for the scheduling of subsequent trades and the ordering of materials for internal works.
In most building contracts, the lock-up stage is considered a key progress payment point, with a portion of the contract sum due to the builder upon reaching this milestone.
Wet Area Waterproofing Inspection
A Wet Area Waterproofing Inspection is an important step in the building process that happens after waterproofing membranes are installed in bathrooms, laundries, and kitchens. These areas are prone to water damage, so the inspector checks the quality of the waterproofing to make sure it meets standards and regulations. They look for any gaps, tears, or problems with the membrane and check that it covers all the necessary areas properly. If everything is done correctly, the builder can then safely install tiles and fixtures without worrying about future water damage.
The Fit-Out Stage
A Fit-out Stage inspection is carried out by a building inspector to assess the installation and quality of non-structural elements such as flooring, ceiling finishes, tiling, cabinetry, fixtures, and fittings, ensuring that they meet the required standards, regulations, and specifications outlined in the building plan.
Interior Walls and Ceilings Inspection
At this phase, walls and ceilings transition from bare frameworks to finished surfaces. Plasterboard is typically fixed to the framing, joints are taped, and multiple layers of compound are applied.
After sanding, the surfaces are ready for undercoats and paint. Skilled workmanship during this stage is crucial for a flawless finish.
Windows and Doors (Joinery / 2nd Fix Carpentry) Inspection
For windows and doors, the inspection will focus on:
- Correct installation: Ensuring they are fitted squarely and securely.
- Sealing: All windows and doors should be sealed properly to prevent drafts and water ingress.
The building inspector will assess the quality of the joinery and second fix carpentry work, checking for proper installation, fit, and finish. They will ensure that all elements are securely fastened, correctly aligned, and free from defects or damage. Any issues identified during this inspection must be rectified by the builder before the building can progress to the final stages of completion and handover.
Final Inspection Stage
The Final Inspection Stage is the last opportunity to ensure the new home meets all quality and compliance benchmarks before ownership is transferred.
Finishing Touches
The building’s aesthetics and functional aspects are scrutinised. Inspectors verify that finishes such as paintwork, trim, and fixtures are properly executed and free from defects.
They review:
- Surface consistency (paint and plaster)
- Fit and finish of all joinery and hardware
- Operation of doors and windows
- Integrity of waterproofing in wet areas
- Installation of appliances
Any defects or issues will be identified and reported, and the builder will be required to rectify them before the building can be handed over to the owner.
Builder’s Warranty Compliance
The builder must fulfil all obligations as per the warranty. Inspection focuses on the construction adhering to:
- Structural integrity regulations
- Electrical, plumbing, and HVAC systems performance
- Compliance with the Building Code of Australia (BCA)
- Manufacturer installation guidelines for warranties on appliances and systems
Post-Construction Review
Once construction is complete, a crucial review process ensures the home meets all the required standards for safety, quality, and compliance. The focus areas are acquiring the necessary occupancy permits and understanding the maintenance and warranty obligations.
Occupancy Permit
An Occupancy Permit is mandatory before a homeowner can legally occupy a new residence. It verifies that the local council has inspected the property and it meets the necessary building codes and standards.
Inspection Criteria:
- Structural integrity
- Fire safety features
- Plumbing, electrical, and gas compliance
- Accessibility features
Maintenance and Warranty Period
During the Maintenance and Warranty Period, homeowners have certain protections and obligations. Builders provide warranties that cover various defects for specified durations.
Maintenance Responsibilities:
- Immediate notification of any defects
- Regular upkeep and appropriate use of the property
Warranty Includes (but not limited to):
- Structural defects: Covered for 6 years.
- Non-structural defects: Often covered for 2 years.
