What we build
What to expect
When patterning with QH&M BIRT
integrity
Founded by Quentin Birt in 1973, we built this business on a simple principle — we do what we say. When we commit to a price, we stick to it. When we commit to a deadline, we meet it. No surprises, no excuses.
Certainty of outcome
We own all of our own plant and employ all of our own people. That means complete control over every project — no subcontractors, no delays, no unexpected costs. Just reliable delivery, every time.
Safety
Safety isn't a box we tick for compliance. It's a culture we build from the ground up on every project. Because at QBirt, our people always come first — on every site, every day.
Delivering for 50 years
The QBirt Story
QBirt, also known as Q H & M Birt, has been successfully delivering civil construction projects for more than 50 years.
We employ all of our own people. We own all of our own plant. Our team is highly skilled and experienced.
At QBirt, we work on some of the biggest civil construction projects in Australia, and we’re proud to attract the very best to work with us.
We’ve been doing this day in, day out for decades, and this is reflected in the quality of our outcomes.
