Structural Engineering That Stands the Test of Time

Whether you're building a new home, extending an existing structure, or developing a large commercial facility, structural engineering is the backbone of every successful build. QED Engineers Civil & Structural Engineers deliver structural design solutions that are technically rigorous, practically buildable, and fully compliant with the National Construction Code (NCC) and all relevant Australian Standards.

Our structural engineers work closely with your builder, architect, and building certifier to produce clear, accurate engineering drawings and documentation that reduce on-site queries and keep your project on program.

Structural Engineering Services

Floor Framing Design

We design floor framing systems for timber and steel-framed residential and commercial buildings, including bearer and joist layouts, LVL beam sizing, composite floor systems, and connection details. Our designs are optimised for span efficiency and material economy.

Wall Framing Design

Our engineers produce detailed wall framing designs covering stud sizing, lintel schedules, wind classification compliance, and connection details — ensuring your wall system performs structurally and meets all relevant code requirements.

Roof Framing Design

From simple hip and gable roofs to complex cathedral ceilings and feature roof forms, we design roof framing systems that are both structurally efficient and architecturally faithful to the design intent.

Structural Steel Design

We design structural steel members and connections for residential and commercial applications, including portal frames, transfer beams, floor steel, columns, balustrades, stairs, and connection plates. All steel designs are produced in accordance with AS 4100.

Suspended Slab Design

We design suspended slab systems including post-tensioned slabs, reinforced concrete flat slabs, and ribbed waffle slabs for residential, multi-residential, and commercial projects.

Subfloor Design — Columns, Piers & Bracing

For elevated floor systems, we design subfloor columns, steel posts, timber stumps, cross bracing, and tie-down systems to resist both gravity and lateral loads.

Void & Portal Frame Design

We deliver structural solutions for feature voids, entry portals, open-plan living configurations, and raked ceilings — enabling striking architectural features while maintaining full structural integrity.

Wall Bracing & Tie-Down Design

Compliant bracing and tie-down designs are critical in cyclonic and high-wind areas. Our engineers produce wall bracing schedules and tie-down details that satisfy wind classification requirements across all Australian wind regions.

Retaining Wall Design

We design retaining walls in timber, concrete block, reinforced concrete, and steel for residential and commercial applications — including detailed footing designs and drainage provisions.

Pool & Pool Fence Engineering

We provide structural engineering for residential and commercial pools, including shell design, pool barrier certification, and associated structural elements such as pool decks and equipment bases.

Alterations & Additions

Existing structures require careful attention. Our engineers assess, design, and document structural modifications for extensions, alterations, renovations, and adaptive reuse projects — preserving structural integrity while enabling your design vision.

Structural Engineering Process

Design Brief

We review your architectural plans, site conditions, and council requirements to establish the structural design brief.

Structural Analysis

Using industry-leading software, our engineers model and analyse the structural system to determine member sizes, connections, and load paths.

Documentation

We produce a complete set of structural drawings and specifications suitable for building approval submission and construction use.

Certification

All structural designs are reviewed and certified by a registered professional engineer, providing you with a fully certifiable engineering package.

Construction Support

We remain available throughout construction for RFIs, site inspections, and engineering certifications at key stages.
