FAQs – Structural Engineering in Sunshine Coast
Do you provide certification for existing decks and carports?
Yes, we offer retrospective structural certification for existing structures such as decks, patios, pergolas, and carports. If your structure was built without council approval, we conduct a thorough inspection to ensure it complies with current Australian standards and Sunshine Coast Council regulations, and we provide the required engineering documentation to support your application.
Can you assist with Sunshine Coast Council regulations?
Definitely. Our engineers are highly familiar with the requirements of the Sunshine Coast Council and other regional authorities. Whether you need pre-construction advice or support with retrospective approvals, we’ll guide you through the documentation, submission, and approval process, making it as stress-free as possible.
How long does a structural inspection take?
A standard structural inspection typically takes 1 to 2 hours on-site, depending on the complexity of the structure. After the inspection, we aim to deliver the engineering report within 2 to 3 business days, although express delivery is available if needed urgently.
Do you work with builders and contractors directly?
Yes, we frequently partner with local builders, draftsmen, and project managers to ensure smooth communication and seamless integration into your building timeline. We can provide engineering designs and certificates that fit into their workflows and are always available for clarification or revisions if required.
What types of structures do you certify?
We provide certification for a wide range of structures, including:
-
Residential homes and extensions
-
Retaining walls and foundations
-
Carports, sheds, and garages
-
Pergolas and verandas
-
Granny flats and auxiliary dwellings
-
Commercial fit-outs and steel framing systems
Is your engineering team licensed and insured?
Absolutely. Every structural engineer on our team is fully qualified, registered, and carries up-to-date professional indemnity and public liability insurance. We comply with all relevant Australian engineering codes and uphold strict quality assurance processes.
Can you help with coastal corrosion-resistant designs?
Yes – designing for coastal areas like the Sunshine Coast requires special attention to corrosion risks due to salt-laden air. We select appropriate materials and apply design principles that reduce long-term degradation. This helps improve structural durability and reduces maintenance costs over time.
What’s the cost for a typical engineering certification?
Our pricing is transparent and competitive. A basic certification starts from around $550, depending on the type and complexity of the structure. We provide a clear, fixed quote upfront with no hidden fees, so you know exactly what to expect before we begin.
Do you offer urgent or express services?
Yes, we understand that some projects require fast action – especially if you’re finalizing a property sale or preparing for an inspection. We offer express service options with turnaround times as fast as 24 hours, depending on the project scope and availability.
