About Us
OUR STORY
Contec Australia delivers structural concrete using 3D concrete printing, operating Western Australia’s first large-scale 3D concrete printing system across residential, commercial, civil, marine, and infrastructure projects.
Applied as a practical construction method, Contec works alongside builders, developers, and project teams to improve speed of delivery, design flexibility, and programme certainty.
Contec Australia has delivered Western Australia’s first 3D concrete printed home, Australia’s first multi-storey 3D concrete printed home, and Australia’s first 3D concrete printed swimming pool, demonstrating real-world capability across structural and architectural applications at multiple scales.
Our Vision
Our vision is to improve how construction is delivered by introducing more efficient and flexible methods that complement traditional construction.
We aim to contribute to a more productive, scalable, and sustainable construction environment across Western Australia.
Our Mission
Our mission is to deliver structural and architectural concrete elements using 3D concrete printing, improving efficiency on site, reducing complexity, and supporting better project outcomes across a range of applications.
Meet our Founder
Contec Australia was founded by Mark D’Alessandro. With extensive experience in Western Australia’s building industry, he identified the need for more efficient construction methods to address labour constraints, rising costs and increasing demand across the construction industry.
Mark introduced 3D concrete printing as a practical solution, delivering structural concrete as a specialist subcontractor using a robotic arm mobile printer, the first large-scale 3D concrete printing system operating in Western Australia.
Contec Australia applies globally proven 3D concrete printing technology across residential, commercial, civil, marine and infrastructure construction, working alongside builders, developers and project teams.
Mark D’Alessandro is also the founder of JCM Property Group, a construction company delivering projects across high-rise, residential, commercial and industrial sectors throughout Western Australia.
With over 20 years of experience, Mark is a Quantity Surveyor and Registered Builder, holding a Bachelor of Applied Science in Construction Management and Economics, along with a Bachelor of Business.
Mark’s experience as a builder and quantity surveyor ensures Contec’s 3D concrete printing integrates seamlessly into standard construction methods and project delivery.
SIGNIFICANTLY SHORTEN CONSTRUCTION TIMELINES
At Contec, we are revolutionising the construction industry with cutting-edge technology and sustainable practices.
What is 3D Concrete Printing?
The 3D Concrete Printing process involves a computer-controlled machine that extrudes layers of concrete, one on top of the other, to build structures directly from a digital model. 3D concrete printing allows for more design freedom and can produce complex shapes and structures that would be difficult or expensive to achieve using conventional techniques.
How does the Contec system work?
1. Digital Design: The process begins with a digital 3D model of the structure, created using computer-aided design (CAD) software. This model provides the precise specifications for the printer to follow.
2. Concrete Mixture: A specialised concrete mix is prepared. This mix is often tailored to be flowable enough to be extruded through the printer nozzle yet quick-setting to support subsequent layers without deformation.
3. Printing Process: The Contec 3D printers large robotic arm follows the digital model’s instructions to extrude the concrete layer by layer. The nozzle moves in precise patterns, depositing the concrete in successive layers to build up the structure.
4. Layering: Each layer is printed in a predefined sequence. The printer ensures that the layers bond together properly, resulting in a solid and cohesive structure.
What are the Benefits of the Contec delivery method?
Speed: 3D concrete printing can significantly reduce construction time compared to traditional methods.
Cost-Effective: It can lower labour costs and reduce material waste.
Design Flexibility: Allows for the creation of complex and custom designs that would be difficult or impossible to achieve with conventional methods.
Sustainability: The process is more environmentally sustainable, as it uses materials more efficiently.
Independent Engineer Certification: Contec provides independent engineering certification from local engineers, based in Australia
