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.







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.
