Gutters and Downpipes Design

This involves the engineering design of eaves, lear, valley, and/or box gutters, as well as the required rainhead and downpipe sizes and locations.

Our design process involves:

  • Reviewing architectural plans
  • Drafting roof layouts (pitch and surface area)
  • A technician review of site-specific rainfall data and client preferences (where applicable)
  • A report compiled by a registered professional engineer

When is it required?

Plumbers, roofers, and builders work from our engineered designs. These designs are based on the capacity to handle a National Construction Code regulated rainfall event, taking into consideration the specific house and location of that house.

What's included?

The PDF report is compiled and signed by a registered professional engineer. The design details typically include (where applicable):

  • Most suitable downpipe locations
  • Most suitable downpipe sizing
  • Most conservative gutter size selections
  • Required overflow specifications

Difficult site experts

We offer best practice solutions in hydraulic design for H, E, and P sites, taking into consideration regulations, practicality, time, and cost savings.

Full service

You can enjoy a smoother, more efficient process by also engaging us for your structural, geotechnical, and foundation engineering needs, as well as soil testing and inspections.

High standards

We design to the highest quality, backed by our experienced engineers’ certification. You can be confident that your project meets all regulations and relevant Australian standards.

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.
