Chapter 20 examines specific emerging technologies and forecasts their adoption timelines and impact on BIM. Internet of Things (IoT) : cheap, wireless sensors are already available. The challenge is not hardware but data management. A single building might generate millions of data points daily. How do you integrate this with the BIM model without overwhelming users?
The authors forecast that by 2028, most new commercial buildings will include IoT as standard, with BIM models designed from the outset to receive and display sensor data.
Machine Learning (ML) : ML algorithms improve automatically through experience. For BIM, ML can automate clash resolution (suggesting how to move a pipe to avoid a beam), classify unlabeled objects in point clouds (identifying "this cluster of points is a chair"), and predict cost overruns based on early project data. Adoption timeline: niche applications available now; mainstream in 3-5 years.
Computer Vision: Using cameras to automatically compare site progress against the BIM model. A drone flies over the site; software identifies which concrete pours are complete, which rebar is in place, and whether the work matches the model. Within 5 years, this may replace manual progress tracking.
5G Networks: Ultra-reliable, low-latency wireless enables real-time collaboration from anywhere. A site worker with a tablet could video-call the designer and overlay model data on the live feed simultaneously. Adoption is rolling out now.
Quantum Computing: Too early for practical construction applications, but potentially transformative for optimization problems (scheduling hundreds of trades, routing thousands of deliveries) that overwhelm classical computers. Timeline: 10+ years.
Digital Thread: The integration of BIM with product manufacturing data, supply chain tracking, and logistics. A door arrives on site with a QR code; scanning it shows which room it belongs to, its installation instructions, and its warranty.
The authors advise organizations to monitor these technologies but avoid chasing hype. The foundation remains solid BIM processes; new technologies augment, not replace, that foundation.
