The digital transformation of the built environment has created a wealth of data across the entire lifecycle of assets. Yet, despite the increasing sophistication of digital design and construction tools, the connection between Building Information Modelling (BIM) and smart building operations remains weak. The gap between BIM and smart buildings is not a technical issue; it is the result of the long-standing divide between project delivery and operational management.
In theory, BIM should be the foundation of smart building development. It provides a structured digital representation of a building’s physical and functional characteristics, enabling informed decision-making from design through to demolition. In practice, however, much of the data created during the design and construction phases is lost, underutilised or incompatible with the systems used to manage and operate buildings.
This ‘project-to-operations gap’ has significant implications for digital construction and building performance. Once a project is handed over, the information-rich BIM model often becomes static. The operational systems that drive smart buildings, such as building management systems (BMS), Internet of Things (IoT) networks, and digital twins, rely on real-time, dynamic data. Without effective integration, the full value of BIM data is never realised, and asset owners are left with disconnected datasets that limit performance insight, energy efficiency, and predictive maintenance.
The root of this challenge lies in how information is exchanged and managed throughout the asset lifecycle. BIM has traditionally been developed with a focus on design and construction stakeholders, using formats and structures optimised for those stages. Meanwhile, smart building technologies operate in a different environment, one that requires interoperable, open data standards and ongoing connectivity. Aligning these worlds requires not only technical integration but also a shift in process, collaboration, and mindset across the built environment ecosystem.
Emerging frameworks and standards are beginning to bridge this gap. The development of digital twins, for example, is driving closer alignment between design data and operational intelligence. By creating a dynamic digital representation of the physical asset, a digital twin enables continuous data exchange between the BIM model and building systems. This allows for performance monitoring, predictive analytics, and evidence-based asset management.
Open data standards such as IFC, COBie and ISO 19650 also play a critical role. They enable structured, machine-readable information that can be shared across software platforms, supporting a more seamless transition from design to operation. As building owners and facility managers increasingly demand access to usable asset data, the industry is moving toward a ‘digital thread’ that connects all project phases into one continuous flow of information.
For this transformation to succeed, collaboration must extend beyond handover. Designers, contractors, operators, and technology providers need to engage from the earliest project stages to define what information will be required for long-term operations. This approach ensures that data is structured, validated, and aligned with operational systems before construction even begins.
Bridging the gap between BIM and smart buildings is, ultimately, about bridging the gap between people, processes, and technology. The tools already exist; the challenge lies in how they are used and shared. By closing the project-to-operations divide, the construction and property sectors can unlock the full potential of digital construction, delivering buildings that are not only smart by design but intelligent in operation.
