Engineering registration, competence and duty of care in Australia: what businesses need to know

Businesses rely on engineering judgement every day, often without calling it that. Someone decides that a modified frame can still carry its load, that a pressure vessel can be repaired, that a mezzanine floor is adequate, or that a machine guard design is safe. When those judgements are sound, nothing happens. When they are not, people can be hurt, assets destroyed and businesses exposed to prosecution, claims and lasting damage to their reputation.

The engineering profession has developed ways to manage this risk: education and accreditation, registration, defined scopes of competence, independent checking, named responsibility and the obligation to speak up. In Australia, these are now reinforced by state registration schemes, work health and safety duties for designers, and statutory duties of care in some sectors. Businesses that commission, employ or supply engineering work benefit from understanding how these fit together, so they can engage the right people, check the right things and protect themselves and others.

This article explains why engineering registration exists, how competence and registration work in Australia, the duties that apply to designers and others, and practical steps a business can take when engaging or managing engineering work. It is general information, not legal advice. Registration and duty requirements differ between states and change over time, so check current requirements with the relevant regulators and seek legal advice for specific situations.

Why registration exists

In 1907, the Quebec Bridge in Canada collapsed during construction, killing 75 workers. The inquiry found that the structure’s own weight had been underestimated and never properly revised as the design developed, that critical compression members were inadequate, and that deformations in those members had been observed and discussed in the period before the collapse without work being stopped. Most of the causes were organisational rather than purely technical: an early assumption not revisited, authority concentrated in one remote person, and evidence of distress reported but not acted on in time.

In the same year, Wyoming became the first American state to require engineers to be licensed. Engineering had reached the point where failures could kill many people at once, and society needed a way to distinguish competent engineers from confident ones. Statutory registration was the answer, and most modern competence frameworks descend from it.

The lessons that the profession took from failures like the Quebec Bridge remain relevant to every business:

• Independent checking: significant designs should be verified by a competent person who has no stake in the original work.
• Authority to stop: people who see evidence of a problem must be able to halt work without waiting for permission.
• Live assumptions: loads, materials and other assumptions must be revisited whenever a design changes.
• Named responsibility: a competent person signs and takes responsibility.

How competence is built and recognised

Engineering registration schemes around the world share four elements:

Supervised experience matters most and gets the least attention. Knowledge can be tested in an examination; judgement about which assumptions are fragile, when a result looks wrong and when to stop is developed over years.

Competence is scoped. An engineer is competent in particular areas of practice, defined by education, experience and current work, not by job title or seniority. A highly experienced mechanical engineer is not automatically competent to design a structural steel building, and an electrical engineer is not automatically competent to design pressure equipment. Competence also fades if not used and maintained.

Registration and recognition in Australia

Australia’s arrangements combine national professional recognition with state legislation:

• Engineers Australia is the national professional body. It accredits engineering degrees, assesses Chartered status and maintains the National Engineering Register.
• Queensland has required registration of professional engineers for many years. Professional engineering services in or for Queensland must generally be carried out by a Registered Professional Engineer of Queensland, or under the direct supervision of one, unless an exemption applies.
• Victoria has a professional engineers registration scheme covering specified areas of engineering.
• New South Wales regulates design and building practitioners for certain building work, including registered professional engineers, and creates a statutory duty of care for construction work under the Design and Building Practitioners Act 2020.
• Other jurisdictions have introduced or are developing their own schemes.

The practical consequence is that the registration required depends on where the work is done or used, the area of engineering and, in some cases, the type of building or project. Engineers working across state borders, and businesses engaging them, need to check requirements for each jurisdiction before work starts.

Duties that apply to designers and businesses

Work health and safety duties

Under the model work health and safety laws adopted in most Australian jurisdictions, designers of plant, structures and substances intended for use at work have a duty to ensure, so far as is reasonably practicable, that the design is without risks to the health and safety of people who make, use, maintain or are otherwise exposed to it. Designers must also carry out testing and analysis and provide information about safe use. Similar duties apply to manufacturers, importers, suppliers and installers.

These duties apply to the business or person who designs, whether or not they are an engineer or registered. A business that modifies a machine, builds a fixture or designs a platform for its own use is a designer for these purposes.

Officers of a business, such as directors and senior managers, must exercise due diligence to ensure the business meets its duties. That includes understanding the hazards of the business’s operations and ensuring appropriate resources and processes are in place.

Plant design registration

Work health and safety regulations require the designs of certain types of plant to be registered before use, such as certain pressure equipment, cranes, lifts and amusement devices. Registration generally requires design verification by a competent person who was not involved in the design. Some plant items also need item registration. Businesses that design, modify or import such plant should check whether registration is required.

Common law and statutory duties of care

Engineers and businesses providing engineering services owe a common law duty of care to those who could foreseeably be harmed by careless work, including people with no contract with them. Some statutory schemes, such as the New South Wales duty for construction work, add express duties. Contracts may impose further obligations, and the Australian Consumer Law requires services to consumers to be provided with due care and skill.

Professional indemnity insurance protects engineers and businesses against claims arising from professional services. Some registration schemes require it, and many clients require it in contracts.

Practical steps when engaging engineering work

1. Define the work and its risks: what is being designed, assessed or certified, and what could go wrong.
2. Check competence and registration: confirm that the engineer is registered where required and competent in the specific area. Ask for evidence of relevant experience, not just a title.
3. Check insurance: confirm professional indemnity cover appropriate to the work.
4. Agree the scope in writing: what is included, which standards apply, what is excluded and what the deliverables are.
5. Document the design basis: loads, standards, assumptions, materials and operating conditions, so they can be checked and revisited.
6. Arrange independent verification for significant or high-risk designs, by a competent person independent of the designer, and required verification for registrable plant.
7. Control changes: any change to the design, materials or use should go back to a competent engineer.
8. Keep records: calculations, drawings, verification reports, registrations and approvals.
9. Make it safe to speak up: anyone who sees a problem should be able to raise it and stop work if needed.

When engineering is bought as part of a product or construction package, such as design and construct contracts or equipment supplied with its own design, responsibility can become blurred. Make clear in the contract who is responsible for design, which standards apply, who verifies the design and what documentation will be handed over. Ask to see the design basis and verification records for safety-critical items, rather than relying on a general statement that the product complies.

The what engineering failures teach a business article draws on failure investigations to show how these controls work in practice.

Managing engineering competence inside a business

Businesses that employ engineers or technical staff can build competence deliberately:

• Map the engineering decisions the business makes and the competence each needs.
• Assign responsibility to people with demonstrated competence, and record who may approve what.
• Provide supervision for developing engineers, so they gain judgement safely.
• Support continuing professional development and registration.
• Use independent checking for significant designs, with reporting lines that make it genuinely independent.
• Know when to get outside help for work beyond in-house competence.

A checker who reports to the designer, or whose job depends on approving the design, is not independent. Independence needs to be designed into reporting lines, not just written into procedures. The turning professional values into repeatable habits article covers building professional standards into daily practice.

A test before signing

Before signing a design, calculation or certificate, an engineer can ask four questions:

• Scope: is this work within my demonstrated competence, and could I show how? If not, who has that competence?
• Basis: are the design assumptions current, documented and consistent with what will actually be built and used?
• Check: has a competent, independent person verified the critical parts, such as load paths and failure modes?
• Evidence: would a reasonable peer reviewing the record after a failure find the reasoning defensible?

Businesses can ask the same questions of the engineering they rely on.

A worked example

This is an illustrative example. A Queensland manufacturer builds a modified work platform for a customer, raising its working height and adding a powered lifting mechanism. The production manager, who has extensive practical experience, plans to design the changes in-house.

Review. Before work begins, the business reviews its obligations. The modification changes the platform’s structural loads and adds powered lifting, which creates significant risks. The business recognises that it is a designer under work health and safety law, that professional engineering services for the structural and mechanical design should be carried out or supervised by a registered professional engineer in Queensland, and that it should check whether the plant type requires design registration.

Actions.

• The business engages a registered engineer with experience in elevating work platforms and structural design, after checking registration, experience and insurance.
• The design basis records loads, applicable standards, the intended use and environmental conditions.
• The engineer’s calculations and drawings are verified by a second competent engineer from a different firm.
• The business checks registration requirements for the plant design with the regulator and follows the required process.
• The production manager contributes practical knowledge of manufacture and assembly, and the risk assessment draws on the people who will build and use the platform.
• Operating and maintenance information is prepared for the customer.

Result. The platform is delivered with documented design, verification and information for safe use. The business can demonstrate how it met its duties, and the customer has confidence in the product. The cost of engineering and verification is small compared with the consequences of a failure.

Applying this in an Australian business

• Recognise when the business is a designer, including for modifications and fixtures.
• Check registration requirements for each state where engineering work is done or used.
• Engage engineers for their specific competence, not just their title.
• Confirm insurance and agree scope in writing.
• Document design bases and revisit them when designs change.
• Arrange independent verification for significant designs and registrable plant.
• Give people authority to stop work when they see a problem.
• Seek legal advice on specific obligations.

Where engineering responsibility goes wrong

• Assuming experience equals competence in an unfamiliar area.
• Not recognising design duties for in-house modifications.
• Checks by people who report to the designer.
• Assumptions made early and never revisited.
• Unregistered engineering where registration is required.
• Warnings raised but not acted on.
• No records of the design basis, verification or approvals.

Questions to ask about the engineering you rely on

• Who designed this, and are they competent and registered for this work?
• What assumptions does the design rely on, and are they still valid?
• Who checked it, and were they independent?
• Does the design need registration or approval before use?
• Who can stop work if something looks wrong?
• Where are the records?

Bringing it together

Engineering registration, competence frameworks and design duties exist because engineering failures can harm many people. In Australia, national professional recognition sits alongside state registration schemes, work health and safety duties for designers and others, plant design registration and common law and statutory duties of care. Businesses manage these well by recognising when they are designers, engaging competent and appropriately registered engineers, documenting design bases, arranging independent verification, controlling changes, keeping records and giving people the authority to speak up and stop work. The result is safer products and workplaces and businesses that can show they have met their obligations.
