INNOVATION
BIM’s potential untapped New technology is ushering in significant changes. IMIESA speaks to Tijs van den Brink, advisory group director: Digital Services, Royal HaskoningDHV, about how recent developments like building information modelling (BIM) are changing the game. How are technology and new developments changing the way industry works? TvdB Information is the key enabler to make anything more efficient. Technologies such as the internet of things (IoT), artificial intelligence (AI), drones, laser scanning, etc. enable us to collect masses of data in a very short time. This data can be increasingly processed at high speeds, assisting us in making informed decisions. Coupled with highbandwidth internet and largevolume data storage, access to the relevant information is available faster and virtually anywhere in the world. Emerging technologies have already had a massive impact in the construction industry. It is transforming everything, from sending drones to inspect and map areas that are unsafe for humans, to 3D printing materials to save time and costs, to using IoT to monitor machines and

predict downtime before it happens. Now, it’s advancing even faster, with new applications and opportunities arising that we’ve yet to consider the impact of – things like autonomous heavy equipment and using AI to scan construction sites to assess the quality and progress of work in real time.
What are the benefits of BIM for infrastructure projects? With more and more data being gathered on construction projects, it is important to standardise the way we collect, store, process and transmit that data. BIM provides us with such a standardised process, while ensuring the availability of the latest information to all interested parties. BIM is a process for creating and managing information on a construction project across the project life cycle. The name falsely suggests it just applies to
buildings – it actually applies to standardisation in the entire built environment. It’s why we sometimes prefer to call it better information management. BIM as a process enables us to make the right decisions at the right time. In gathering data from all stakeholders involved on a project (including clients, engineers, architects, construction teams and contractors) and storing it in one place – the model – the entire team is on the same page – from concept, to construction, future operations, maintenance and renovation. In the model, we create a single source of the truth. Then, BIM software brings all this information to life in a visually engaging and interactive way. It’s not only a 3D representation of how a building will look and feel once it’s constructed, but it also gives insights into its inner workings. This enables the project team to test different scenarios and resources before construction starts – like a dress rehearsal before the big show. The benefit of this is that things happen faster, more efficiently, and more accurately. Beyond efficiency, an additional benefit of adopting BIM and working with a single version of the truth is traceability – it is a very, very transparent process.
With BIM, even before starting work on-site, the project team can test different layouts and construction techniques, avoid incompatible designs and spatial clashes, identify structural problems, improve the facility’s carbon footprint, and enhance on-site safety, for example. The challenge with adopting BIM, and we see this currently, is that it requires a bit of investment in learning and mastering the process, the standards and tooling available. This is a deterrent for some of the parties involved, but there are some school fees to be paid to unlock the cost savings unlocked by managing information better – across the life cycle of the asset.
Is government likely to insist on the use of BIM for public projects in the future? The value in BIM is in standardisation, and government has a crucial role to play there. If not standardised in South Africa, BIM could be just another way of working. We trust governments will see the benefits of cost saving and transparency and will follow the lead of the UK, Singapore, UAE and Scandinavian countries, insisting on its use in the future.
