Queensland’s Subdivision Engineering Specialists
Start with our free subdivision check for an instant preliminary result — then get a formal written feasibility report from a Registered Professional Engineer of Queensland (RPEQ), typically delivered within 24 hours.
What We Do
End-to-end civil engineering for Queensland residential and rural subdivisions — from desktop feasibility through to construction sign-off.
Desktop assessments of your lot delivered within 24 hours. Know if subdivision is viable before committing to expensive design fees.
Full preparation and lodgement of Reconfiguring a Lot (RAL) applications with Queensland councils, including all supporting engineering reports.
Detailed civil engineering plans to satisfy council approval conditions and progress your subdivision from DA approval to operational works.
Full civil design and documentation for all infrastructure works required to construct your subdivision to council standards.
Hydraulic analysis and stormwater management design to satisfy council requirements and protect your development from flood risk.
Maximise your land’s yield while minimising construction costs. We design for the highest number of lots without compromising buildability or approval.
The Journey
A clear, proven five-step pathway from your first question to your new lots being titled and ready to sell.
A desktop assessment using council mapping, flood overlays, subdivisional rules, and title data. Delivered in 24 hours so you know if subdivision is viable — before spending a dollar on design.
24-Hour TurnaroundWe prepare and lodge your Reconfiguring a Lot (RAL) application with council — including layout plans, engineering reports, and all supporting documentation to achieve approval.
Typically 3–6 MonthsOnce DA is approved, we produce the detailed engineering and survey plans required to satisfy all council conditions and progress to operational works approval.
Full design of roads, drainage, stormwater, water, and sewer infrastructure. All documentation required for contractor tendering and council operational works approval.
We inspect works during construction, certify completion as RPEQ, and manage the on-maintenance period through to final council approval — and your new lot titles.
RPEQ Certified Sign-OffDelivered within 24 hours
Not Sure If You Can Subdivide?
Use our free online subdivision checker for an instant preliminary assessment based on your council’s zoning rules. When you’re ready for a formal report by a Registered Professional Engineer of Queensland (RPEQ) — covering council overlays, infrastructure connections, flood constraints, and a written professional opinion — order our $450 Feasibility Assessment, typically delivered within 24 hours.

About Civil Subdivisions QLD
Civil Subdivisions Queensland is a specialist subdivision engineering practice. Unlike large firms that handle everything, we focus exclusively on Queensland residential and rural subdivisions — which means faster turnarounds, sharper cost focus, and an engineer who knows exactly what your council needs.
All projects are completed by a Chartered Professional Engineer (CPEng), a member of Engineers Australia, and a Registered Professional Engineer of Queensland (RPEQ) — so you can be confident every assessment, design and certification meets the highest professional standard required under Queensland legislation.
The highest standard of engineering practice in Australia, awarded by Engineers Australia.
All designs certified by a Registered Professional Engineer of Queensland as required by law.
We design for buildability and value — reducing your construction costs while maximising lot yield.
Common Questions
Everything you need to know about subdividing your property in Queensland.
Whether you can subdivide depends on your lot’s zoning, size, shape, and any planning overlays (flood, bushfire, etc.) that apply. Most residential lots in Queensland can potentially be subdivided if large enough to create two or more lots that meet minimum size requirements. The best first step is a feasibility study to check all relevant constraints before committing to design costs.
Minimum lot sizes vary by council and zoning. In Brisbane’s Low Density Residential zone, the general minimum is 400m² per lot with a 10m+ frontage. Other councils and zones have different requirements. Rural and rural residential zones typically have much larger minimums — sometimes 2ha or more. Our feasibility study checks the specific minimum for your property’s council area and zone.
The overall process typically takes 12–24 months from feasibility to titled lots, depending on complexity. Council assessment of the Development Application (DA) usually takes 3–6 months. After DA approval, operational works design and approval takes a further 2–4 months. Construction for a small residential subdivision is typically 3–6 months. Title issue happens after construction and on-maintenance sign-off.
A Reconfiguring a Lot (RAL) application is the formal development application lodged with council to seek approval to subdivide your land. It is assessed under the Planning Act 2016 and the relevant council’s planning scheme. The RAL application includes a proposed lot layout plan, engineering reports, and supporting documentation. Approval of the RAL is required before any subdivision works can commence.
Operational Works (OPW) approval is a secondary approval from council covering the construction of infrastructure — roads, drainage, water, and sewer connections. It is almost always required for residential subdivisions. OPW approval requires detailed engineering design drawings and specifications to be submitted and approved before construction can begin. We handle full OPW design and lodgement as part of our service.
Yes. Under Queensland legislation, all engineering design for subdivision infrastructure — roads, drainage, stormwater, water and sewer — must be designed and certified by a Registered Professional Engineer of Queensland (RPEQ). Councils will not accept engineering drawings that are not RPEQ-certified. Civil Subdivisions Queensland is RPEQ registered and all designs are certified accordingly.
Costs vary by project size and complexity. As a general guide: a $450 RPEQ formal feasibility assessment report; Development Application engineering typically $3,000–$8,000; and full Operational Works design for a small residential subdivision (2–10 lots) is typically $8,000–$25,000. We provide fixed-fee proposals after reviewing your property so there are no surprises. Our cost-focused design approach also actively looks to reduce your construction costs.
Potentially yes. Many Queensland properties are affected by flood or overland flow overlays that restrict how land can be subdivided. These are checked in our feasibility study. In many cases, flood constraints can be managed through careful lot layout, fill levels, or stormwater detention design — we assess all options and give you clear advice on what’s achievable and at what cost.
Just your property address and what you’d like to achieve — for example, “I want to create two lots from my 1,200m² block.” We can source all planning and mapping data from the address. If you have the property title or survey plan available, that’s helpful but not essential for the initial feasibility check. Contact us or order a $450 RPEQ feasibility assessment to get started.
