Why work with us

What you can expect when you choose QBirt for your project


QBirt was founded by Quentin Birt, who has been in the business of contracting since 1973. We’re one of the only contractors that still embraces the historical business values of integrity, honesty, and reliability. When we say we’ll do something, we do it. When we commit to a price, we stick to it. We’ll always do right by you because we believe that’s the way that business should be.


When you choose QBirt for your project, you can depend upon a quality output. We pride ourselves on the consistent quality of our work and our team of experienced experts at every level.

Certainty of outcome, delivery on time

Employing all of our own team members and owning all of our own fleet means that you get a whole lot of certainty for your project. There are no unexpected delays or surprises because we manage everything in-house.​


We are honest, open, communicative and keep you in the loop with your project.

Environment and Sustainability

We are committed to cultural preservation, environment and sustainability. We take the environment, culture and community seriously and do all that we can to ensure we operate for the benefit of all.


Seeking “value for money” for our clients at every opportunity, eliminating waste or unnecessary costs, seeking “win-win” outcomes to the challenges that inevitably arise on large, complex construction projects


Safety is so much more to us than a box to tick for compliance. We instil a culture of safety and ensure it takes priority in every project, because, to us, people always come first. 

Our secret is in our team

Our people are the best in the business

From our management team, project administrators and head office staff, engineers and surveyors through to our plant operators, machinery workshop staff and HSE advisors, we take a huge amount of pride in our team.

We do end-to-end project management and delivery of major construction projects across Australia, and have a large team of experts that make this possible.

We’re proud to say that we attract the best to work with us.

You'll love the experience, knowledge, personal and professional growth that comes from working as part of a high-functioning team to overcome challenges and make a tangible impact to the works that are unfolding on-site. With a modern fleet and a multi-skilled team, you’ll be an integral part of a very big picture, work on some great projects, and get recognised for your ability.


At all roles and stages within our team, our people benefit from an accelerated career path. You don’t have to climb the ladder or deal with workplace politics; you’ll be promoted as fast as your ability allows. Examples of this progression include Graduate Engineers that are now Senior Project Managers, Operators that are now HSE Managers, Superintendents, Supervisors, Trainers and Surveyors, Labourers that are now HSW Advisors and Apprentices that are now Workshop Managers.
