Converge and Gammon create first digital twin of concreting on site

Converge in collaboration with Gammon Construction Limited, a joint venture between Balfour Beatty and Jardine Matheson, has created the world’s first digital twin of site concreting, thanks to the launch of the latest version of Converge’s pioneering concrete maturity platform, ConcreteDNATM.

ConcreteDNA's new product tier ConcreteDNA Pro (Pro), integrates concrete sensor data with building information modelling and provides in-depth material performance analytics to form the first iteration of a real-time digital twin.

The enabling hardware behind the ConcreteDNA platform is a powerful embedded sensor called Converge Signal which measures the compressive strength of concrete as it cures. The new cellular gateway introduced in Pro, Converge Signal, automatically transmits sensor data to the cloud in real time. Previously, concrete data had to be collected manually via the Converge app. Pro introduces concrete performance and temperature differential analytics to the platform, which means project teams can track and ensure concrete is meeting expected standards. With this added certainty, cube testing procedures can be reduced, resulting in lower carbon emissions. Thanks to ConcreteDNA Pro, Gammon saved over 110 t of concrete waste by reducing testing by approximately 14 000 cubes on its Hong Kong Science & Technology Parks Corporation’s Advanced Manufacturing Centre (AMC) project in Hong Kong. Insights from performance analytics facilitates optimisation of materials by selecting the right mix to suit programme requirements, meaning less cement is used and the project has a smaller carbon footprint.
