What is Regulation 126 certificate of compliance for proposed building work?

In Victoria, a Certificate of Compliance is a document that is regulated by the Victorian Building Authority and is referred to as “Regulation 126: Certificate of Compliance – Design”. The Victorian Building Authority administers Victoria’s building legislation system. The document is a statement made by the engineer (us) to the Building Surveyor that all structural design works have been carried out in accordance with the Building Act 1993, the Building Regulations 2018, the National Construction Code and the relevant Australian Standards.​

There are two parts to Regulation 126.

1. Regulation 126 Certificate of Compliance - Design
2. Regulation 126 Certificate of Compliance - Inspection

What is Reg 126 Inspection for?

Reg 126 - Inspection is a certificate report issued by a registered civil engineer, certifying the structural adequacy of the structure as built & / or detailing any amendments required to upgrade the structure.

Reg. 126 design certificates also extend to installation of a construction of a building. After having regard to the complexity of a design, the RBS may determine that an independent inspection of the installation is required. ArchiEng offers inspection and certification services for Civil, Structural, column, walls, retaining walls, verandah, fence, alfresco, light-gauge steel (LGS), seismic ceiling solutions.

What project requires Reg 126 Inspection?

For commercial projects, inspection requests by structural engineer can be carried out on concrete, columns, structural steel, lightweight steel LGS, retaining walls, suspended ceilings, seismic restraints etc.

For domestic building works, such as houses, walls, fence, verandahs, a regulation 126 (Certificate of Compliance for Building Work) must be provided.

For businesses, parklet for road side and outdoor dining is a popular demand for Reg 126 Design and Reg 126 Inspection Certificates.

Here are a few examples from Bayside Council regarding Parklets on Roads Policy, Yarra City Council, Monash City Council, City of Stonnington or City of Kingston.

Prior to undertaking any parklet design works, the business owner must gain support from Council in regard to their proposed parklet location. The business owner must have a valid Footpath Trading Permit and is to follow the application process as outlined in the Parklet Policy, including provision of a Road Safety Audit. The parklets are to be designed by a qualified professional, with structures designed by a registered Engineer or Architect.

• The Engineer must certify the structural design by submitting a Certificate of Compliance (Reg 126) – Design.

• Upon completion of construction, the Engineer must inspect and issue a Certificate of Compliance (Reg 126) – Inspection.

What is the appropriate pathway in the case where an inspection was not undertaken of an already constructed slab/footing? Is there an appropriate pathway for a Reg126 inspection certificate to be issued by an engineer from assessment of the slab?

‍

The Building Act 1993 and Building Regulations 2018 requires the mandatory inspections to be listed and to be carried out after the builder has notified the Relevant Building Surveyor of the completion of that stage of the building work. Further the Relevant Building Surveyor also has the power under Section 35 of the Act to carry out any other inspections where appropriate. Where work has already commenced without notifying the Relevant Building Surveyor, this is considered a breach of the legislation and further the Relevant Building Surveyor could also ask for the work to be demolished, opened, or cut in to, tested etc., if required to be satisfied that the work complies. All building mandatory inspections are required to also be carried out in person and the certificate of compliance for the building work should only be issued when the inspector can be satisfied the building work complies even if work was required to be opened or cut in to for demonstrating compliance.
