Civil + Structural Solutions
Who we are
Engineering Confidence. Creating Better Places.
We are a Sydney-based consultancy delivering civil and structural engineering for residential, commercial, industrial and public infrastructure projects across New South Wales and Western Australia.
Both disciplines sit in one office under one project lead, so drainage, levels, structure and buildability are resolved together rather than negotiated between consultants after the fact.
Integrity
We give the honest engineering answer, including when it is not the easy one.
Collaboration
We work inside your project team, not at arm's length from it.
Excellence
Every package is peer checked before it leaves the office.
Accountability
We own our documents through design, approval and construction.
Our Services
Five service lines, one accountable team
From bulk earthworks and stormwater through to structural certification and remedial works.
Not sure what you need?
Send us the drawings and we will scope it for you
We will tell you what engineering input the project actually requires — and what it does not.
Why Aetera
Engineering you can build from
Four commitments that shape every package we issue.
Cost-effective Scheme
Options assessed early so the adopted scheme balances buildability, program and construction cost — not just compliance.
Sustainable Design
Water sensitive urban design, material efficiency and low-carbon structural solutions built into the design brief.
Strict Code Compliance
Design to the National Construction Code, Australian Standards and the relevant council and authority requirements.
On-time Drawing Delivery
Committed issue dates, clear revision control and drawing packages that arrive when your program needs them.
