Certificates of Compliance: Why do you require Regulation 126A - Design and and Regulation 126B - Inspection


When it comes to building and construction in Victoria, compliance with the regulations set by the Victorian Building Authority (VBA) is paramount. Among these regulations, two certificates play a crucial role in ensuring that building designs and constructions meet the required standards: the Certificate of Compliance – Design (Regulation 126A) and the Certificate of Compliance – Inspection on as-built (Regulation 126B).

Understanding Regulation 126A and 126B

Regulation 126A Design

Regulation 126A: Certificate of Compliance – Design

Adherence to Building Regulations

The primary purpose of the Regulation 126A certificate is to confirm that the design of a building complies with all applicable building regulations and standards. These regulations are put in place to ensure the safety, health, and welfare of the building's occupants, as well as to promote sustainable construction practices. Regulation 126A mandates that a Certificate of Compliance must be issued for building designs. This certificate confirms that the design complies with all applicable building regulations and standards. It is a critical step in the planning phase, ensuring that the proposed design is safe, functional, and legally sound before any construction begins.

Avoiding Legal and Financial Repercussions

Non-compliance with building regulations can result in significant legal and financial repercussions. Without the Regulation 126A certificate, projects may face fines, delays, or even legal action. Ensuring compliance from the outset helps avoid these potential pitfalls and keeps the project on track and within budget.

Protecting Occupants and Users

One of the most critical aspects of the Regulation 126A certificate is the assurance that the building design is safe for its intended use. This includes meeting fire safety standards, structural integrity requirements, and accessibility provisions. Ensuring that these elements are considered and integrated into the design phase helps protect future occupants and users of the building.

Mitigating Risks

By securing a Regulation 126A certificate, designers and builders can identify and mitigate potential risks early in the project. This proactive approach can prevent costly modifications during or after construction and ensures that the project proceeds smoothly and safely.

A Regulation 126A certificate is often a prerequisite for obtaining further approvals and permits from local councils and other regulatory bodies. Having this certificate in hand demonstrates that the design has been thoroughly vetted and meets all necessary criteria, thereby streamlining the approval process and reducing the likelihood of delays.

Regulation 126B inspection as built Victoria

Regulation 126B: Certificate of Compliance – Inspection on as-built

Verification of Design Implementation

The Regulation 126B certificate confirms that the completed building aligns with the approved design documented in the Regulation 126A certificate. This verification process ensures that all aspects of the design have been accurately executed, preserving the integrity and intent of the original plans. Regulation 126B requires a Certificate of Compliance for the actual construction or "as-built" structure. This certificate verifies that the completed building or structure adheres to the approved design and complies with all relevant regulations. It is an assurance that the finished project is safe, compliant, and ready for occupancy or use.

Preventing Unauthorized Modifications

Throughout the construction phase, unauthorized changes can sometimes occur, whether due to misunderstandings, on-site decisions, or other factors. The Regulation 126B inspection helps identify and rectify any deviations from the approved design, ensuring the final structure complies with the original regulatory approvals.

Comprehensive Safety Checks

One of the core purposes of the Regulation 126B certificate is to ensure that the built structure is safe for occupancy and use. This includes verifying that all safety features, such as fire exits, structural supports, and emergency systems, are properly installed and functional.

Assurance of Structural Integrity

The inspection process involves a thorough examination of the building’s structural components to ensure they meet all required standards. This helps to prevent potential issues that could compromise the building's integrity, providing peace of mind to occupants and owners.

Required for Occupancy Permits

In many cases, obtaining a Regulation 126B certificate is a prerequisite for securing an occupancy permit from local authorities. This certificate is a formal declaration that the building is compliant and safe for its intended use, thereby facilitating the transition from construction to occupancy.

Smoothing the Handover Process

The Regulation 126B certificate streamlines the handover process from builders to owners or tenants. It acts as an official endorsement that the building has been constructed to the highest standards, ensuring a smooth and hassle-free handover.
