Contec Australia

Contec Australia is a Western Australian construction subcontractor that operates the state's first large-scale 3D concrete printing system. Founded by Mark D'Alessandro, a Quantity Surveyor and Registered Builder with more than 20 years of industry experience and degrees in construction management, economics, and business, the company positions itself as a specialist trade contractor rather than a general builder, supplying printed structural and architectural concrete elements to residential, commercial, civil, and marine projects. Its core equipment is a mobile crawler-type 3D concrete printer that deposits layered concrete on site or in an off-site production facility, eliminating the need for conventional timber or steel formwork on printed elements such as walls, columns, pool shells, and landscape features. Contec reports that its printing process cuts material waste by more than 80% compared with conventional formwork-based concrete construction and reduces embodied CO2 emissions by roughly 30%, figures the company attributes to eliminating formwork materials and reducing on-site labor and machinery time. The company's highest-profile project to date is the Tapping residence, described as Australia's first multi-storey 3D concrete printed home, which Contec completed in about five months, a project covered by industry outlets including 3D Printing Industry and Built Offsite. In August 2026, Contec completed what it describes as Australia's first 3D-concrete-printed swimming pool structure, extending its printed-concrete capability from vertical walls to curved pool shells. The company also supplies precast and printed permanent formwork for civil and marine infrastructure applications. Contec states that its printed structural elements are certified by independent Australian structural engineers, a step it highlights as necessary since 3D concrete printing is not yet covered by standard Australian building codes in the same way as conventional reinforced concrete. The company's public materials do not disclose a specific founding year, employee count, or the manufacturer of its printing hardware, though earlier press coverage from CyBe Construction indicates a relationship with a Netherlands-based 3D construction printer supplier when the Western Australian system was first introduced. Contec operates primarily as a subcontractor delivering printed concrete packages to builders and developers, rather than as a direct-to-consumer home builder, and its contact channels are limited to a single Claremont office phone number and email address alongside active Facebook and Instagram accounts documenting completed projects.
