FORM 15
The Importance of a Form 15 – Structural Engineering Services
What is a Form 15?
A Form 15 – Compliance Certificate for Building Design or Specification is a critical document used in the construction industry, particularly in Queensland, Australia. It is issued by a Registered Professional Engineer of Queensland (RPEQ) and serves as an official confirmation that a specific design, plan, or specification adheres to relevant Australian Standards, Building Codes, and local council requirements.
This certificate is a fundamental part of the building approval process, helping ensure that all structural and design aspects of a project are legally compliant and structurally sound. Without this form, obtaining necessary approvals from building certifiers and local councils may become a challenge, potentially delaying construction or even leading to costly modifications.
When this form is issued, it means that the engineering or design work has been reviewed by a certified professional, verifying that it meets all safety and quality standards required for regulatory compliance. This document is commonly needed for projects involving structural elements, civil works, or specialised engineering components, making it an indispensable part of the construction approval process..

Why is a Form 15 Important?
1. Ensures Regulatory Compliance
This form acts as an official document confirming that structural and engineering designs adhere to national and state regulations. These include compliance with the National Construction Code (NCC), Australian Standards, and local council requirements. It assures building certifiers and local authorities that all engineering aspects of the project have been reviewed and approved by a qualified professional.
2. Required for Building Approvals
In Queensland, most residential and commercial projects require this form before construction can commence. Without this certificate, a building project may not receive approval, leading to delays, potential fines, or legal complications. Ensuring you have the correct documentation in place is essential to a smooth approval process.
3. Supports Insurance and Compliance
This form is often required by insurance companies to validate structural work in the event of damage or disputes. Additionally, having a properly certified design helps demonstrate due diligence in compliance with safety standards, reducing risks for builders, property owners, and developers.
4. Provides Peace of Mind
When you obtain this form, you can be confident that your project is designed to meet high safety and durability standards. This minimises the likelihood of structural failures, safety hazards, or legal challenges related to engineering integrity.
5. Protects Your Investment
Building a home, commercial space, or renovation project is a significant financial investment. By ensuring that you obtain this form, you’re protecting your financial interests by guaranteeing that your structure is engineered for safety and longevity.
When Do You Need a Form 15?
This form is required in numerous building scenarios, including:
- New Home Builds – Certifying foundation designs, structural framing, retaining walls, and load-bearing elements to meet engineering and safety standards.
- Home Extension & Renovations – Ensuring that modifications such as room additions, structural alterations, or loft conversions are safe and compliant.
- Swimming Pools – Certifying the structural integrity of pool foundations, reinforcement specifications, and retaining walls surrounding the pool area.
- Decks & Patios – Verifying that the design meets engineering and load-bearing standards for longevity and safety.
- Carports: Inspecting construction quality to meet structural and safety standards
- Retaining Walls – Providing engineering certification for blockwork, concrete sleeper walls, Dincel walls, and sandstone retaining walls to ensure proper load distribution and structural durability.
- Shed Slabs: Ensuring durability & appropriate slab soil interaction.
- Wall Removal Projects: Providing inspection certification for load-bearing wall removals.
If you’re unsure whether your project requires a Form 15, consulting with Mellan Consulting Engineers can help you determine your certification needs and keep your project moving forward without delays.
The Role of a Structural Engineer in Form 15 Certification
A structural engineer plays a crucial role in issuing a Form 15. Their responsibilities include:
- Assessing structural integrity – Ensuring that the design can withstand environmental forces and load requirements.
- Reviewing engineering documentation – Checking drawings, specifications, and reports for compliance.
- Conducting site inspections – Verifying construction conditions and foundation stability.
- Providing professional certification – Issuing to confirm that designs comply with regulatory standards.
By working with a qualified RPEQ-certified engineer, you can ensure that your project is built to last and fully compliant with Queensland regulations.
