INFORMATION MODELLING IN TUNNELLING
The matrix of procedures, processes and responsibilities in how to manage information in tunnelling projects in the era of BIM was the focus of guidance published last year by ITA’s Working Group 22. T&T looks at key points and recommendations
The report isn’t long, at all. But it is packed with helpfully structured tables and graphics, and three appendices, plus
references into 36 key pages, plus extras. For a report focused on managing information it sure does efficiently shoehorn great quantities of detail in compact forms into its pages. Excellent, not to get lost in. Which is always the danger with reams of
information in the real world. And reports. Why was the report needed? In the era of spreading digital networks,
more powerful software, fantastic computer processing speed and memory, and colossal storage capability, those features of information
technology services are making sufficient inroads to the infrastructure asset and construction sectors that they are helping to catalyse generation of far more data. That, in turn,
is spawning ways to exchange, stack and store the mountain of information that seems to never stop mushrooming. The ways and means of working with these data hubs and hierarchies of holding are giving rise to new concepts, such as Building Information Modelling (BIM), Digital Twins (DT), and more. Concept is arguably a reasonable terms
for positioning BIM and DT for neither are fully understood or agreed upon. It depends where you are in the supply chain and, even so, ultimately what a client – or your supply chain neighbours – want. What they will pay for. In the short- or long-term. Is digital and data in service of the build alone or is
the vision much, much longer, to encompass lifecycle economics, and operations and maintenance, and smart ways to get and pick over the data, digitally. Thoroughly. Quickly. Continuously. All depends. Given all that, all that can be pulled together by

engineers and managers in their field of endeavour to see how such possibilities with data and digital, with BIM and DT, might be shaping up is worthwhile. And when the report is structured well, for digestion, at speed, then doubly so.
