Wind Classification

Wind classification is required for building approvals as it determines specific design requirements, including construction methods and performance requirements.

Structures need to withstand various external loads, including wind, which can vary greatly between sites.

The process involves:

  • Site assessment — wind region, topography, shielding, terrain
  • Cross check with site database
  • Wind classification and report

When is it required?

The wind classification gives builders, suppliers, designers, and clients the insights they need to design and quote correctly. It gives them the correct design and construction specifications, such as frame bracing and tie downs, window/cladding and fixings, and minimum structural member sizes and appropriate connections. This means clients or owners are more aware of costs up front.

Wind classification is often done in conjunction with a site classification soil test.

What's included?

Wind classification involves the following steps:

  • Determining which wind standard (AS4055 or AS1170.2) applies, depending on proposed structure and site location
  • Site visit to assess and document shielding and exposure (trees, other buildings, parks, open spaces) — this usually forms part of the soil classification site visit, when booked at the same time
  • On-site information recorded and cross-checked with our site database of completed nearby wind assessments and estate mapping, using appropriate software and calculations
  • A qualified technician determines wind classification
  • We compile and approve a PDF report

Low cost

For economy of scale, you can arrange your wind classification at the same time as your soil test.

Optimised compliance

An early engineer’s assessment means we can apply the correct standard (AS4055 or AS1170.2), which avoids hold ups later down the track.

The latest tools

We have an extensive site database (as well as the latest software in-house) to ensure you receive a quality report.

One engineer for all your needs

Every building project is different, requiring a combination of engineering disciplines. From bottom to top, our engineers can work on soil testing and foundations, all the way up to frame and roof truss design and even inspections. We believe these shouldn’t be thought of as separate, unrelated services.

Whether you’re renovating, extending, building a brand new home, or putting in a pool, you can gain significant benefits from understanding (in advance) the full range of engineering services you might need — and from using the same engineer for all these services.

Key advantages of integrated services

STA is a one-stop engineer with a service range that delivers three key advantages:

  • Save time and money

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.

  • Enjoy engineering continuity

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.

  • Less risk, more reliability

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.

How it works

Engineering consideration – We help you think about your project in engineering terms. What specific services might you need?
Packaged plan – We develop a plan that packages up all the engineering services you need for your individual home or build project.
Prescheduled services – With each service pre-scheduled, we can work more closely with you over the life of the project.
