CONSTRUCTION STAGE INSPECTIONS

Site Preparation & Groundwork

We assess the site preparation, including excavation depth and site levels, to ensure they align with the approved engineering plans, which is crucial for a stable and level foundation. We also check if soil compaction meets required standards, to provide a stable base for the concrete slab and prevent potential settlement issues and cracks.

Vapour Barrier Installation

We verify that the vapour barrier membrane is correctly installed, covering the entire area beneath the slab to prevent moisture ingress. Any damage to the membrane is noted for immediate rectification.

Termite Protection

We ensure that termite protection measures, such as chemical treatments or physical barriers, are correctly applied and meet the requirements of Australian Standards. This is critical for protecting the building from future termite infestations.

Reinforcement Steel

We ensure the correct placement of reinforcement steel, verify proper spacing and support, and confirm penetration locations are accurately positioned and protected, maintaining the slab’s structural integrity.

Concrete Formwork

We inspect the formwork for proper alignment and levelness to ensure the slab is poured to the correct dimensions with a level surface. We also verify that the formwork provides the correct concrete cover over the reinforcement steel, as specified in the engineering plans and standards, to protect against corrosion and ensure the slab’s durability.

Slab Thickness & Edge Beams

We verify that the slab thickness meets the engineering specifications to provide the necessary load-bearing capacity for the structure. Additionally, we check the dimensions and placement of edge beams and footings to ensure they comply with approved plans, providing essential support for the building’s perimeter and load-bearing walls.

Documentation & Review

Before work begins, we review all construction drawings and documentation to identify any potential issues or discrepancies that need to be addressed during the slab and steel stage. During the inspection, we compare the as-built conditions with the approved plans and engineering specifications to ensure all work is performed exactly as designed.

Concrete Slab Assessment

We inspect the concrete slab for exposed steel around its perimeter, which can lead to rust and structural weakness over time. We also examine the slab’s surface finish for signs of excessive cracking, peeling, or dusting to ensure it meets durability and aesthetic standards. Additionally, we measure the levelness of the slab across all floor levels, identifying any deviations that could impact the structural integrity.

Wall Frame & Bracing

We thoroughly check the wall frames for plumbness and straightness to ensure they meet design specifications and provide a solid base for the rest of the construction. We also verify that the bracing complies with the NCC, Australian Timber Framing Code, and approved engineering designs, ensuring the building can withstand wind loads and other forces. We inspect all framing materials for quality, checking for any signs of damage, warping, or other issues that could compromise the structure.

Roof Truss System

We ensure the roof truss layout matches the approved plans and provides strong support for roofing materials. We check the installation and bracing against manufacturer specifications and Australian Standards, guaranteeing a stable, secure roof structure. Lastly, we inspect all connections, including nail plates and fixings, to confirm they are properly installed and offer the required strength and stability.

Engineering Compliance

We systematically review the entire structure to ensure it complies with the approved engineering design, checking that all elements are correctly positioned and securely connected. Additionally, we verify that the locations of penetrations for services like plumbing and electrical do not compromise the structural integrity of the frame and are correctly placed according to the plans.

Construction Drawings Review

Before construction begins, we thoroughly review the construction drawings and documentation to identify any potential issues or discrepancies that need to be addressed. During the inspection, we then compare the as-built structure against the approved plans and engineering specifications to ensure all work has been carried out as designed.

Window & Door Installation

We inspect the window frames for proper installation and alignment, ensuring that they are securely fitted and function correctly. Our expertise ensures that your windows not only meet all safety and performance standards but also contribute to the overall energy efficiency of your home.

Guttering, Fascia & Eaves

These elements are checked for levelness, straightness, and correct installation. We ensure that they are not only aesthetically pleasing but also functional and durable.

Roofline & Tile Installation

The roofline is inspected for correct alignment and structural integrity. We assess the installation of roof tiles or sheeting, ensuring that they comply with both manufacturer specifications and Australian Standards.

Roof Plumbing Assessment

We assess all aspects of roof plumbing, including the installation of downpipes, rainheads, and overflow systems. This ensures that the roof drainage is adequate to prevent water ingress, which could lead to structural damage or moisture-related issues.

Timber Door Sills

We verify the proper flashing and sealing of timber door sills to ensure they are fully protected from water ingress.

Articulation Joints, Flashings & Weepholes

We confirm the proper placement of articulation joints, flashings, and weepholes to ensure structural flexibility and water drainage.

Brickwork & Slab Interface

The brick walls are inspected to ensure they bear correctly on the concrete slab, with appropriate clearances and no debris or excessive mortar in the cavities.

Cladding Installation

We compare the installation of the specific type of cladding used on your property against the manufacturer’s Technical Data Sheet (TDS) and installation requirements. This ensures that the cladding is installed as per the manufacturer’s guidelines, which is critical for maintaining the cladding’s warranty, durability, and performance.

External Features

We assess the correct installation of external elements such as timber door sills, articulation joints, flashings, and weep holes. These components are vital for preventing moisture ingress and maintaining the structural integrity of the building.

DFT (Dry Film Thickness) Assessment

We utilise an advanced ultrasound device to measure the Dry Film Thickness of the waterproofing membrane. This ensures that the application meets the specifications outlined in the manufacturer’s Technical Data Sheets (TDS) and provides the required protection.

Comparison to Manufacturer’s TDS Documentation

We compare the installed waterproofing system with the manufacturer’s TDS documentation to verify that the application aligns with the recommended guidelines for both the waterproofing product and the substrate preparation.

Compliance with NCC and AS 3740

We check that the waterproofing system conforms to the National Construction Code (NCC) and the relevant Australian Standards, including AS 3740:2010 and AS 3740:2021. This ensures that the waterproofing is compliant with current regulations and best practices.

Adhesion Testing

Where necessary, we conduct adhesion testing to verify that the waterproofing membrane is properly bonded to the substrate, ensuring long-term performance and durability.

Substrate Preparation and Waterproofing Application

Where necessary, we assess all aspects of the substrate preparation and waterproofing application to confirm that they meet the required standards and manufacturer’s guidelines.

Integration with External Finishes

We ensure that the waterproofing system is correctly integrated with external finishes, checking that the cladding or substrate has been installed in accordance with the manufacturer’s TDS prior to the waterproofing application. This is crucial for maintaining the integrity of both the waterproofing system and the external finishes.

Removal of Interior Finishes

If necessary, and with the consent of the builder or client, we will remove interior finishes to fully assess the waterproofing system and identify any potential issues that may compromise the waterproofing integrity.
