Send your drawings, sketches, photos or the letter from council. We review the scope and tell you exactly what’s needed and what it costs.
PDF plans are preferred. Please export DWG/DXF drawings to PDF where possible. JPG and PNG photos are welcome.
Add your site address and a short description. That’s it.
Three steps from first enquiry to drawings you can lodge with council or your certifier.
Share your plans, sketches or site details. Please give the maximum dimensions you want quoted. Increasing them later may require a revised quote.
We confirm exactly what the engineering covers and what it costs. Nothing to pay until you accept.
After acceptance and payment, we prepare your stamped drawings and answer any council questions about them if needed.

A direct point of contact for your ongoing structural engineering, standard details and repeat designs.
Engineering Online Australia has prepared structural engineering for more than 5,000 projects since 2013. Here is what that looks like for you.
Wind region, terrain and soil drive the design. You buy the steel you need, not what a generic table guesses.
If your council or certifier has a question about our engineering, we answer it and revise if needed at no extra charge.
You see the scope and price before you commit. No hourly rates and no surprise invoices.
Everything happens by email and phone, so nothing waits on an appointment.
Degree-qualified Chartered Professional Engineers, registered in every Australian state and territory, including RPEQ in Queensland.
Tell us the proposed materials for your accepted structure. Include the relevant PDF plans so we can assess the engineering scope.
Whatever you have. A sketch with dimensions, photos, a kit brochure, architectural plans or the letter from council all help. The two things we always need are the size of the structure and the site address (or at least the suburb), because wind region and soil change the design.
Yes. Our drawings are prepared for building permit and development applications across Australia. If council comes back with a question about our engineering, forward it to us and we will respond. We do not lodge applications for you, but we make sure the engineering side is ready to lodge.
Not for sheds, patios, carports or container buildings. A dimensioned sketch is usually enough, and for sheds and patios you can build your design in our online tools. For house extensions and new homes we work from your architectural or drafted plans.
That is how we work with everyone. You send your details online, we quote by email, and your engineer is available by phone if you want to talk it through. No office visits or site visits are needed. We provide engineering services only, so materials, construction, soil testing and site inspections are arranged separately.
We work in every Australian state and territory, including cyclonic regions. In South Australia we currently take shed and patio/carport projects.
