CONVERGENCE OF BIM AND DIGITAL TWINS
INSIDE THE
Tor Erik Djupos, application engineer with Trimble, discusses the influence and convergence of BIM and Digital Twins for infrastructure assets
Advancements in Building Information Modelling (BIM) and the subsequent emergence of Digital Twins have widespread implications for tunnel owners, designers, engineers and contractors. BIM already directly influences the way assets are
designed and built, reducing rework and facilitating more collective collaboration. Digital Twins, or ‘live models’, have the potential to push that evolving digital framework to a whole new level. While many might see the primary value of a Digital
Twin in its ability to manage an asset in real-time, it’s much more. This ‘model of truth’ becomes a basis from which owners and project partners can simulate asset behaviour and drive improvement with an emphasis on safety, community and environmental outcomes.
FROM OUTCOME TO OPTIMISATION For a growing number of transportation entities, BIM or the utilisation of a 3D model is an essential piece of a collaborative design-to-construction process,
and for some, is an integral piece to maintenance and operational activities. The US Federal Highway Administration (FHA)
recently said: “Using digital data such as 3D models to build road projects is becoming an industry standard. Sharing the design model and associated digital project data allows agencies and contractors to streamline project delivery and contract administration and to collaborate on challenges ‘virtually’ before they get to the field.” European countries are leading the way in the
investment and implementation of BIM. Norway’s highway authorities already rely on what
they call a ‘constructible BIM’, a model delivery that has been required for many years. By demanding BIM, these organisations have experienced significant cost reductions in the form of fewer errors and fewer change orders. This also includes fewer conflicts, because all parties understand a model and hence have a better overall picture of the project.
