If you need an RPEQ engineer in Queensland to certify, review, or sign off engineering work, Black Square Engineering provides RPEQ-led certification, verification, and compliance services for SMEs, industrial operators, and asset owners.
Our RPEQ engineers are directly involved in design reviews, inspections, certification, and reporting — delivering practical, defensible outcomes aligned with Queensland legislation and industry standards.
Whether it’s a straightforward sign-off or a more complex engineering assessment, we provide clear advice and reliable certification to meet your statutory obligations.
What Our RPEQ Engineers Provide
Our services include:
We work across mechanical, structural, and industrial applications where registered professional oversight is required.
When Is an RPEQ Engineer Required?
Engaging an RPEQ engineer is typically required when:
-
Certifying regulated plant or equipment
-
Signing statutory compliance documentation
-
Verifying engineering designs or modifications
-
Providing independent engineering review
We help clients understand when RPEQ involvement is mandatory — and when it is simply prudent.
Form 15, Certification, and Compliance Documentation
Our RPEQ engineers prepare and review Form 14 certification where required, ensuring:
-
Engineering work complies with applicable standards
-
Design intent and assumptions are clearly documented
We focus on clarity, accuracy, and proportionality — avoiding unnecessary complexity.
Client Responsibilities
While we provide professional engineering services, clients remain responsible for:
-
Supplying accurate design and operational information
-
Implementing certified designs correctly
-
Maintaining assets post-certification
-
Meeting ongoing inspection and maintenance obligations
We make these responsibilities explicit to reduce compliance risk.

RPEQ Engineering & Certification FAQs
When do I need an RPEQ engineer?
An RPEQ engineer is generally required whenever professional engineering services are carried out in Queensland and the work is considered to be professional engineering under the Professional Engineers Act 2002 (Qld).
This commonly includes engineering design, certification, design verification, structural assessments, pressure equipment, lifting equipment, machinery modifications and engineering reports.
If you're unsure whether your project requires an RPEQ engineer, obtaining advice early can help avoid delays and ensure the work meets Queensland's legislative requirements.
What does an RPEQ engineer certify?
An RPEQ engineer may certify that an engineering design, assessment or verification has been completed in accordance with the relevant legislation, Australian Standards and accepted engineering practice.
The exact scope of certification depends on the project. It may relate to structural steel, mechanical systems, pressure equipment, lifting devices, plant modifications or other engineering works.
Certification provides documented evidence that the engineering has been independently assessed by a suitably qualified Registered Professional Engineer of Queensland.
Is an RPEQ engineer legally required in Queensland?
In many situations, yes.
Queensland legislation requires professional engineering services to be carried out or directly supervised by an RPEQ unless a specific exemption applies.
The requirement exists to ensure engineering decisions that affect public safety are made by appropriately qualified and accountable professionals.
Determining whether an exemption applies can depend on the nature of the work, so obtaining engineering advice early is often the most practical approach.
Can an RPEQ certify existing plant or machinery?
Yes. Existing plant, machinery and industrial equipment can often be assessed and certified where appropriate.
The process may include reviewing available design information, inspecting the equipment, undertaking engineering calculations and assessing compliance with the relevant Australian Standards and legislative requirements.
This is commonly required for imported machinery, modified equipment, ageing assets and plant where original engineering documentation is incomplete or unavailable.
What information does an RPEQ engineer need before providing certification?
The information required depends on the project, but generally includes available drawings, design calculations, equipment specifications, operating conditions and details of any modifications or repairs.
Where documentation is incomplete, an engineering inspection or additional assessment may be required to establish whether the asset complies with the relevant engineering requirements.
Providing accurate information at the start of the project helps streamline the certification process and reduces the likelihood of delays during assessment.
