Identify those hidden issues before it is too late –
before the builder’s liability is extinguished or a major failure.


Designers and builders have numerous contractual, statutory and authorities’ compliance obligations such as:

  • The National Construction Code and the associated Building Code of Australia;
  • Compliance with Australian Standards;
  • Safety in Design obligations;
  • Energy Efficiency obligations in the form of statutory or voluntary obligations such as Green Star or NABERS;
  • Local authorities’, State, and Federal authorities’ regulatory requirements;
  • Specific Owners requirements;
  • Technical drawings and specifications requirements;
  • Specialist Designer requirements in regard to the use of specific products or equipment;
  • Specialist Manufacturers and Vendor requirements in relation to the use of their products or equipment;
  • Other stakeholders in the building process;
  • Environmental;
  • Health and Safety; and
  • Community

Building Owners, Operators and Maintainers also have obligations in regard to the correct use and maintenance of buildings as defined in the Builder’s O & M Manuals, the maintenance of safety measures and energy efficiency requirements as defined in the WA Building Regulations, and compliance with local and state government and utilities authorities’ requirements.

During the Defects and statutory Builders Liability periods, various design, construction, operations or maintenance issues may become apparent. It is important these are thoroughly reviewed to determine the extent, cause, impacts, and corrective actions, if any, and that corrective action implementation plans are documented and managed in order not to compromise current and future building operations, maintenance, liabilities and warrantees.

Defects may manifest themselves in many ways. Most commonly, defects are seen as physical in nature and relate to cracking or water damage or some other undesirable physical change or breakage. Defects however may also be concealed behind building finishes or fabric and may also manifest in issues such as a services system inability to meet demand or excess down time, air pressurisation issues, excess energy water or chemical demand, additional maintenance, faulty control and detection systems, material degradation or movement, moisture damage and corrosion that may be difficult to interpret. In our experience, these concealed defects are less often identified and notified to builders for attention, during the defects and liability periods.

The most significant defects issues impacting the design life of the building structure, fabric or finishes are often identified after the expiry of the Builders Liability Period when they become physically manifest to a layman. Unfortunately this is also when the damage is more widespread, advanced and costly to fix and most detrimentally for the owner, when the Builder’s Liability has expired.

Through our extensive experience with building design, construction, handovers and defects management activities on all classes of buildings, CCC assists in identifying and resolving defects issues. We review documentation and records, inspect the works, undertake necessary testing in accordance with the brief, assess the compliance of design and construction and provide the necessary defects management to resolve defects, warrantee and liability claims that may result.


In recent years there have been a number of high profile cases that have tested the builder’s and contractor’s liability for defects. The most significant lessons learned from these cases are:

  • that the owner ( or their representative) is responsible to identify and notify the builder of a defect;
  • that building contract defect rectification activities should be assessed, monitored and approved to avoid ineffective or untimely repairs and errors in their acceptance;
  • Outstanding Builders Liability claims must be lodged with the WA Building Commissioner prior to the expiry of the Defects Liability Period, 6 years from Practical Completion.

Don’t leave your claim until the last minute or you may find your rights compromised through inability to implement the necessary claims processes.
