New Construction Inspections

New Construction Inspections Perth

Research has indicated that there are problems in around 22 per cent of all building projects. Industry wide, these problems result in millions of dollars worth of costs when dealing with the contractural and construction issues, in rectifying defective work and/ or resolving disputes.

Problems generally arise from concerns surrounding issues relating to the quality of building work, concerns about the contract, or scope of building work.

We provide detailed building inspection reports that include photos of any defects.

The reports categorise the defects into 4 main groups:

  • Safety Hazards
  • BCA Non – Compliance
  • Sub Standard Workmanship
  • Contracts and Specification – Non – Compliance

Any major issues are referenced back to the National Construction Code ( B.C.A ), Guide To Standards & Tolerances 2015 or the relevant Australian Standard.

The 4 main building inspection stages in your new construction build to consider are:

  • Slab
  • Plate Height (brickwork)
  • Roof Frame
  • Handover

Regulated Building Standards – New Construction Inspections

The regulated standards for building a new home in Western Australia are for the most part covered within the National Construction Code (Building Code of Australia), which all builders are required to comply with.

There is a hierarchy for building standards, which starts with the Act of Parliament, regulations under the Act, the National Construction Code, then the Australian Standards and additional documentation referenced by the B.C.A.

During new construction inspections, the Guide to Standards and Tolerances 2015 is commonly referenced for workmanship issues that fall outside of the Australian Standards requirements.

It is important to note though, that this is only a guide and not a regulated standard. Most builders however, recognise this advisory document and rectify the defective workmanship itemised in each report to a suitable standard.

Where there is any disagreement over defective work, the BCA or building contract takes precedence.

Our building inspection reports differ from that of our competitors, in that each itemised defect is referred back to the applicable Building code or Australian Standard requirement. The specific clause number (e.g: AS 1684 clause 7.2.4) is listed along with its specification provision.

Each building element is assessed to note any apparent deviations and defected if found to exceed the allowable minimum or maximum tolerances.

Given the Western Australian new build housing industry is largely self-regulated, the builders will generally rectify these issues without question, once they receive the new construction inspection report.

Defects categorised as Sub-standard workmanship in each report, includes all works undertaken by contractors or sub-contractors employed by the builder.

Blemishes & Variations

Defective finishes such as paintwork and render are another common complaint. When viewing blemishes and variations, they must be viewed and/or visible from a normal viewing position during new construction inspections.

A normal viewing position is defined as a distance of 1.5 m or greater and 600 mm for fixtures and appliances.

The surface inspected must have diffused light that is not parallel or glancing. This is classified as non-critical light.

It is highly advised that after final handover of the build, the owner performs regular maintenance to ensure the structure continues to perform as intended. By adopting simple landscaping techniques, owners can also reduce the risk of damage and cracking to the buildings structure.

Typically, maintenance plans include the following items to be considered: blocked gutters, faulty sprinkler systems, overflows from air-conditioners, proximity of trees to house, resealing of shower recesses, downpipes unconnected to stormwater and paving sloping towards building.

Housing Industry AssociationWhat is Practical Completion?

As the building process draws to an end, the builder will issue you with a date & time for a Practical Completion Inspection, typically referred to as a PCI.

Depending upon the builder’s requirements, we either attend site to conduct the PCI several days prior to your meeting, or at the same time which is generally the preferred process for the site supervisors.

We conduct our assessment of the build while the supervisor carries out the site meeting with the client. This typically takes between 1 – 1.5 hours for a standard 4 x 2 home.

At the end of our inspection, a verbal assessment detailing general areas of concern is entered between the client’s, site supervisor and the inspector.

A written report detailing specific areas of non-compliance and substandard workmanship issues is then emailed within 24 hours. The builder will then have 10 working days, from receiving the report to rectify the identified items.

The PCI will include an assessment of all works completed to ensure all structural and building materials have been installed within the allowable tolerances.

Blue tape will be places on all areas of concern during the inspection. This helps the supervisor to identify the defective areas and allows the relevant trades to rectify these issues.
