What to expect when you work with Aeonic Engineering
We understand that time is the pressure point on most residential projects. Our process is built around giving you exactly what you need, when you need it — without the back and forth that slows projects down.
When you engage us, you deal directly with the engineer on your project. We take the time to understand what you’re trying to achieve — not just technically, but practically. That means we explain what the engineering requires, why it’s required, and what it means for your builder or certifier. For first-time builders or developers new to the process, we provide as much guidance as the project needs. For experienced professionals, we stay out of the way and deliver clean documentation on time.
We also provide value engineering as a standard part of our process — reviewing structural solutions for efficiency so you’re not paying to build more structure than the project actually needs.

Frequently asked questions
What does a residential structural engineer do?
A residential structural engineer designs and certifies the structural elements of your home — the components that carry load and keep the building safe and stable. This includes foundations and footings, floor and roof framing, beams and columns, retaining walls, and any structural alterations to an existing building. On a new build or duplex, the structural engineer works alongside your architect to produce the engineering drawings and calculations your certifier needs for approval. On an alteration or addition, we assess the existing structure, identify what needs to change, and design a solution that integrates cleanly with the original building.
Do I need a structural engineer for a duplex in NSW?
Yes. A duplex is a Class 1 building under the National Construction Code and requires structural engineering documentation as part of the DA or CDC approval process. This includes structural design drawings, engineering calculations, and certification by a registered structural engineer. At Aeonic Engineering, duplex structural design is one of our most common project types — we know what councils and certifiers require across Greater Sydney and produce documentation that moves through the approval process efficiently.
How long does residential structural engineering take?
It depends on the project type and complexity. For a straightforward alteration or addition, structural documentation can typically be produced within a few days of receiving the architectural plans. For residential duplex projects, turnaround time varies depending on the structure, site conditions, and the completeness of information provided. Once all required information is in hand — including architectural drawings, completed structural coordination, and any relevant geotechnical or survey data — we target delivery within two weeks. We’ll confirm a realistic timeframe at the start of every engagement and keep you informed throughout.
