Structural & Civil Engineers in Brisbane

Building, renovating or developing in Brisbane or South-East Queensland? QED Engineers delivers RPEQ-registered structural and civil engineering — from house extensions, decks and retaining walls to multi-residential and commercial projects. We provide clear, buildable, code-compliant designs and move quickly, with a fee proposal typically back to you within 24 hours.

RPEQ-registered engineering — and Form 15 & Form 16 certification

In Queensland, the Professional Engineers Act requires professional engineering services to be provided or supervised by a Registered Professional Engineer of Queensland (RPEQ). QED Engineers is RPEQ-registered, so your designs are compliant from the start.

We also provide Form 15 (Compliance Certificate for Building Design or Specification) and Form 16 (Inspection Certificate / Aspect Certificate) — the RPEQ-signed certificates your building certifier needs to approve and progress your build. If you've been asked for a Form 15 or Form 16, we can help.

Engineering for Brisbane's soils and climate

Brisbane is well known for highly reactive clay soils that shrink and swell dramatically between the wet and dry — a leading cause of cracked slabs and footing movement when a build isn't engineered for it. Getting the site classification right (to AS 2870 — often Class M, H1/H2 or E in Brisbane) is essential to protect your slab without over-spending.

The city's hilly, sloping terrain means retaining walls, split-level footings and drainage design are everyday considerations, while Brisbane's subtropical storms, heavy downpours and flood-prone catchments make stormwater and civil design a core part of getting projects approved. We design with these local conditions in mind so your documentation satisfies council the first time.

Areas we serve across South-East Queensland

Frequently asked questions

Yes — as an RPEQ-registered practice, QED can provide Form 15 design compliance certificates and Form 16 aspect/inspection certificates required by your building certifier.
Professional engineering services in Queensland must be carried out or supervised by a Registered Professional Engineer of Queensland (RPEQ). QED Engineers is RPEQ-registered, so your structural and civil designs meet this requirement.
It depends on scope — a single beam design for a wall removal differs greatly from a full home or a unit development. Simple residential jobs are usually a fixed fee; larger projects are quoted on scope. Send your plans for an itemised fee proposal, typically within 24 hours.
Brisbane's reactive clays move significantly with moisture. A correct site classification (AS 2870) lets us design footings that resist this movement, avoiding cracking and unnecessary cost.
Yes. Sloping and split-level sites are common across Brisbane, and we regularly design retaining walls, drainage and footings tailored to the slope and soil of each site.
Yes. Altering a load-bearing wall changes how loads travel through the building, so an engineer must design a beam and supports to carry the load safely. We provide the design and any certification your certifier requires.
