A retaining wall design is not always needed. But if the wall is 800mm or above, you’ll usually need an engineered design as per AS4678 to ensure council approval, longevity of the wall, and peace of mind.
The design gives your builder precise specifications to follow. We recommend using a builder who is suitably licensed to build retaining walls.
A registered professional engineer will compile and sign your PDF report. The design details typically include (where applicable):
There isn’t a retaining wall we haven’t seen or designed. We have years of experience in providing varied and custom retaining wall designs to suit client needs.
STA’s own Risk Matrix determines the level of engineering analysis and geotechnical testing. This reduces engineering time, meaning faster turnaround that saves you time and money.
Our clear, consistent, repeatable processes help to build a better client–engineer relationship.
STA is a one-stop engineer with a service range that delivers three key advantages:
Pre-planning your engineering needs means you won’t have to keep re-booking an engineer when you need a particular service. It creates efficiencies that cut service times and save you money by pulling together the services you’ll need, at a lower overall price.
With all your engineering done by a single organisation, your consultants tap into a deeper knowledge of the site and the project, which leads to high quality outcomes, with more opportunities for innovative solutions.
While STA always takes legal responsibility for its engineering designs, an up-front engineering services package makes it easier to trust our work with a strong mutual commitment, and reduced risk of potential interruption or delay.
