An Engineer’s Guide to Certifications

Certifications issued by engineers are vital in ensuring that construction works meet design specifications, safety standards, and legal requirements. These certifications are often relied upon by clients to make critical decisions, such as approving payments to contractors or assessing compliance with building codes. However, issuing inspection certificates comes with significant legal responsibilities.

Why Are On-Site Inspections Important?

Identifying Deviations from Design

A design is only as effective as its implementation. Engineers must ensure that construction aligns with design documents, including measurements, boundaries, and construction steps. During on-site inspections, engineers should identify any deviations from the design and address them promptly.

Timely responses to Requests for Information (RFIs) and clear communication with contractors are essential to prevent errors that could lead to liability.

Detecting Construction Defects

On-site inspections are critical for identifying construction defects. Engineers should categorise defects by severity and assess their impact on the project. These findings should be documented in a report, supported by visual evidence and references to relevant codes or standards.

Defects must be communicated clearly and urgently to ensure timely rectification. Engineers should also follow up to confirm that corrective actions have been taken.

Legal Obligations of Engineers

Duty of Care

Under Australian law, engineers owe a duty of care to their clients. This duty requires engineers to exercise reasonable skill, care, and diligence in their work. Failure to meet this standard can result in liability for damages if the client suffers a loss due to negligence.

For example, an engineer who negligently certifies defective work may be held liable for the resulting financial losses incurred by the client.

Obligation to Warn

Engineers have a legal obligation to warn clients or contractors of foreseeable risks that could lead to harm. This duty requires proactive communication of potential issues during inspections or certifications. Failing to provide adequate warnings can result in liability if harm occurs.

Acting Independently

Engineers must act independently and impartially when issuing inspection certificates. While engineers are often contracted and paid by clients, they must resist external pressures and ensure their decisions are fair and unbiased.

Negligent or fraudulent certifications can expose engineers to legal claims from both clients and contractors. For instance:

  • if an engineer negligently certifies incomplete work, the client may overpay the contractor and suffer financial losses
  • if an engineer provides misleading information about site conditions, they may be liable for damages incurred by the contractor

Misleading and Deceptive Conduct

Liability Under the Competition and Consumer Act 2010 (Cth)

Engineers may face claims of misleading or deceptive conduct under section 18 of the Competition and Consumer Act 2010 (Cth) if their certifications are inaccurate or misleading.

Mistrina Pty Ltd v Australian Consulting Engineers Pty Ltd [2020] NSWCA 223

In this case, a design engineer was held liable for certifying a structurally defective raft slab as compliant with the Building Code of Australia. The certification led to significant financial losses for the property developer, even though the engineer was not directly contracted by the developer.

This case highlights the importance of accuracy and due diligence in issuing certifications.

Practical Considerations for Engineers

Defining the Scope of Certification

Certifications must clearly define their scope to avoid misunderstandings. Engineers should limit their certifications to areas within their expertise and avoid making speculative statements.

Preparing for On-Site Inspections

  • Thoroughly review project plans, specifications, and relevant codes before attending the site
  • Adhere to safety protocols and use appropriate personal protective equipment during inspections

Effective Communication

Transparent communication with stakeholders is essential. Engineers should promptly notify clients or contractors of any non-compliance or defects identified during inspections. Delayed communication can exacerbate issues and increase liability risks.

Precise Documentation

Accurate documentation is crucial for legal defence. Engineers should maintain contemporaneous notes, photographs, and detailed reports of their findings during inspections.

Avoiding Scope Creep

Engineers must avoid stepping outside their professional expertise during inspections or certifications. For example:

  • do not comment on architectural works unless they interface with engineering work
  • avoid advising contractors on product selection or application methods
