Modelling and simulation, virtual and augmented realities… Supported by the maturity of new technologies, digitisation has spread to the design, operation and maintenance of buildings, factories and energy grids, but also to the administration of entire cities.
BIM VS Digital Twins: What is the difference?
During a round table discussion with several partners, Jérôme Dakono, Solutions Architect at Microsoft, Sarah Hassen, BIM and Facilities Management Manager at Bouygues Energies & Services in France and Jonathan Jones, BIM Manager and R&D Project Manager at Bouygues Energies & Services in the UK, shared their vision of the digital twin.
“People usually think that a digital twin is a BIM model,” explains Sarah Hassen. Actually,the most common definition refers to the exchange of data that takes place with an asset, real or digital, throughout the building’s life cycle.”Sarah Hassen
Jérôme Dakono of Microsoft says: “A digital twin in construction is a data integration platform that combines all the enriched data you can get on buildings.” It is therefore a system able to collect data from several sources and model the whole building, with all this information, in a graphical database: IoT and operational data, corporate data, including HR, or BIM data.
Jonathan Jones says, “In our industry, we have determined that a digital twin involves digitally connecting the status of assets or processes, to a virtual representation for a functional outcome. Not to mention a logical interaction between the virtual results, i.e. the results generated by the digital twin, and a business process.”
According to Jonathan, five main functions can be dened for digital twins in general: a visualisation function, a capture, detection or monitoring function, an activation, operation and improvement function, a simulation function and a prediction function.
