Structural Engineer Report — Brisbane & Queensland
A structural engineer report is a formal written document prepared and signed by a Registered Professional Engineer of Queensland (RPEQ) that assesses the structural condition, compliance or design of a building or structure. It may certify a structural design for council (Form 15), document damage for an insurance claim, identify defects for a QBCC dispute, or provide an expert structural opinion for legal proceedings. In Queensland, structural reports used for building approvals or legal matters must be signed by an RPEQ engineer.
Brisbane Structures is an RPEQ-certified structural engineering firm based in Brisbane, providing structural engineer reports for residential, commercial and industrial properties across Queensland. Our reports are independently prepared, professionally presented and built to withstand scrutiny — from building certifiers and insurers through to QBCC and the courts.
Whether you need a simple Form 15 design certificate to get your building approval over the line, a detailed pre-purchase inspection report before you commit to a property, or an expert structural opinion for a QBCC complaint or legal matter — we prepare the right document for your purpose and issue it within clear, agreed timelines.

What's Included
While the exact contents vary by report type, every structural engineer report from Brisbane Structures is structured clearly, referenced to Australian Standards where applicable, and signed by an RPEQ engineer. Below is what each major category of report typically covers.
When You Need One
A structural engineer report may be required by your building certifier, council, insurer, the QBCC, a court — or you may need one to protect your own interests before buying or selling a property. Here are the most common situations where a structural report is needed in Queensland.
Any building work involving structural elements — new homes, extensions, decks, carports, retaining walls, commercial fitouts — requires a Form 15 structural engineering certificate before a building certifier can issue approval. This is a legal requirement in Queensland under the Building Act 1975.
If you plan to remove a load-bearing wall, modify a structural beam, or alter the load path of a building, a structural engineer must assess the work, design the replacement structure and provide an RPEQ-signed report and drawings before your builder can start.
Before buying a property — especially older homes, properties with visible cracking, or buildings that have been renovated — a structural engineer report provides an expert assessment of structural integrity that a standard building inspection cannot provide. It may reveal foundation movement, frame issues or defective work that affects the property's value or safety.
Insurers require an RPEQ-signed structural damage assessment report to process claims for flood, storm, subsidence, fire or impact damage. The report documents the cause and extent of structural damage and recommends remediation — giving the insurer the technical evidence needed to assess and pay the claim.
If you believe a builder has produced defective or non-compliant structural work, the QBCC process requires independent engineering evidence. An RPEQ structural report documenting the defects, the applicable standards, and the remediation required is central to a successful QBCC complaint.
Queensland law requires owner-builders who sell within 6 years of completing work to have an owner-builder insurance inspection completed by a licensed inspector and — where structural work is involved — a structural engineer report. This protects buyers and is required before settlement can proceed.
Structural engineer reports are used as expert evidence in QCAT hearings, court proceedings, arbitration and mediation involving building disputes, property damage claims and construction contract disputes. These reports are prepared to specific admissibility standards and carry the professional liability of the RPEQ signatory.
Before excavation, demolition or significant construction begins next to your property, a dilapidation survey by an RPEQ engineer documents the existing condition of your building. If construction causes damage, the pre-work report provides the baseline evidence needed to support a claim.

We deliver your RPEQ-signed structural engineer report — ready for your building certifier, insurer, QBCC, solicitor or conveyancer.
Structural Report vs Building Inspection
Many property buyers and owners are uncertain about the difference between a structural engineer report and a standard building inspection report. Both are useful tools, but they serve different purposes and carry different professional weight.
A building inspection report is prepared by a licensed building inspector (not necessarily an engineer). It covers a broad range of items across the whole building — moisture, pests, roof condition, plumbing, electrical, compliance — but treats structural elements at a general, visual level. A building inspector cannot provide engineering calculations, certify structural adequacy or issue a Form 15.
A structural engineer report is prepared by a Registered Professional Engineer of Queensland (RPEQ). It focuses specifically on the structural elements — foundations, frames, beams, slabs and load-bearing walls — and may include engineering calculations, Australian Standards references and professional certification. An RPEQ structural report is the only document accepted by building certifiers, councils, the QBCC and courts in Queensland for structural matters.
If your building inspector identifies a crack, foundation movement or any structural concern in their report, they will typically recommend obtaining a separate structural engineer report. Brisbane Structures can provide that follow-up structural assessment quickly, usually within 2–5 business days.
Common Questions
A structural engineer report is a formal written document prepared and signed by an RPEQ (Registered Professional Engineer of Queensland) that assesses the structural condition, design compliance or integrity of a building. It is used for building approvals (Form 15), insurance claims, pre-purchase inspections, QBCC disputes and legal proceedings.
Yes. Any structural engineering report used for building approvals, council submissions, QBCC proceedings or insurance claims in Queensland must be signed and sealed by an RPEQ. Reports signed by engineers not registered under the Professional Engineers Act 2002 (Qld) are not accepted by building certifiers, councils or the QBCC.
Cost depends on report type, property size and whether a site inspection is needed. Brisbane Structures provides fixed-fee quotes within 24 hours of enquiry — no obligation. We also offer a price-match guarantee: show us a written quote from a comparable RPEQ firm in Queensland and we'll match it plus take 10% off.
Brisbane Structures delivers most structural reports within 2–5 business days of site inspection. Form 15 certifications where drawings are already available can typically be issued within 3 business days. Urgent turnaround is available — contact us to discuss your timeline and we'll confirm what's achievable.
Yes. An RPEQ pre-purchase structural inspection report provides a detailed assessment of the structural condition of a property — foundations, frames, slabs, roof structure and load-bearing walls. It is more detailed than a standard building inspection for structural matters and is accepted by banks, solicitors and conveyancers in Queensland.
A Form 15 is a specific Queensland document — a QBCC design certificate signed by an RPEQ engineer to certify that structural design drawings and calculations comply with Australian Standards and the National Construction Code. It is required by building certifiers before issuing a building approval. A structural report is a broader term that covers inspection reports, damage assessments, QBCC dispute reports and other RPEQ-signed engineering documents.
Yes. Brisbane Structures has experience with older Queensland homes, heritage buildings and structures built under previous codes. We assess these properties against both current Australian Standards and any heritage or pre-existing approval conditions that apply, providing practical recommendations that respect the property's construction period and heritage status where relevant.
Yes. Brisbane Structures provides structural engineer reports across Queensland — including the Gold Coast, Sunshine Coast, Ipswich, Toowoomba, Logan, and regional Queensland. Travel fees may apply for remote locations; contact us with your address for a quote that covers your location.
