What is BIM?

Building Information Modelling (BIM) is a digital method revolutionising the design, construction, and management of infrastructures. Unlike traditional design methods, BIM enables the creation of a unique digital model that integrates not only the physical dimensions of the building but also critical information such as materials, costs, timelines, and even sustainability. This centralised, intelligent model allows project stakeholders to collaborate in real time, ensuring consistency across the various stages of a building’s lifecycle. BIM is now recognised as an approach that enhances accuracy, reduces costs, and optimises the efficiency of construction projects.

Fundamental concepts of BIM

Definition and core principles

BIM goes beyond simple Computer-Aided Design (CAD), extending far past 2D and 3D models. It represents a data management method that centralises all relevant information within a unique digital model. This dynamic model enables all stakeholders to collaborate and view modifications in real time, thereby reducing errors. When changes are made to one building component, they are automatically reflected across all related representations. This centralisation ensures better coordination and helps anticipate impacts at each project phase. A prime example of a tool embodying this approach is Revit, which centralises data modelling for real-time collaboration.

BIM dimensionality: from 3D to 7D

BIM involves multiple dimensions beyond traditional 3D modelling. Besides 3D, it includes 4D, which focuses on time management and enables dynamic project phase planning. 5D integrates cost estimation, allowing for real-time budget tracking and precise adjustments. 6D addresses energy performance and environmental sustainability, a key consideration for projects targeting ecological compliance. Finally, 7D concerns lifecycle facility management, from maintenance to future adaptation. Navisworks is a robust tool aiding in 4D planning and complex model coordination.

BIM standards and regulations

BIM implementation is governed by international standards such as ISO 19650, which defines best practices for information management within a construction project. These standards ensure a standardised approach, facilitating collaboration among stakeholders through common data management procedures. For instance, ISO 19650 mandates structured data storage, guaranteeing optimal traceability and accessibility for all involved parties. BIM users must also adhere to data-sharing protocols, enhancing project transparency and consistency. Tools like Solibri verify model compliance with required norms and standards.

Practical applications of BIM

Architectural design and collaboration

BIM has transformed the collaboration between architects, engineers, and other building professionals. It offers a single digital platform where each participant can make modifications, view changes, and suggest solutions in real time, minimising the risk of incompatibility between disciplines. A Dodge Data & Analytics (2018) study revealed that BIM reduces design errors by 30% and improves interdisciplinary coordination. BIMcollab simplifies collaboration by streamlining issue management and communication.

Construction and virtual simulation

One of BIM’s major advantages is its capacity to simulate each construction phase before actual work begins. Virtual models help teams identify and resolve potential conflicts among building components, whether related to piping layout, electrical cabling, or structural elements. This early conflict detection significantly reduces delays and the costs of last-minute corrections. A McKinsey & Company (2017) study showed that BIM integration in construction projects cuts costs by 20% through improved accuracy and risk management. Tekla Structures is one tool used to manage and simulate complex phases.

Maintenance and infrastructure management

BIM extends beyond design and construction, serving as a valuable tool for continuous building management. After project completion, infrastructure managers can use the BIM model as an interactive database for monitoring technical systems and planning maintenance interventions. This enables proactive equipment management and optimised energy efficiency. According to the National Institute of Building Sciences (NIBS), using BIM for facility management reduces operational costs by 20% through better-planned maintenance and optimised energy consumption. ArchiFM is one example of a tool that facilitates proactive management.

Operational management and Surfy utilisation

BIM proves valuable in operational management, optimising building and workspace maintenance. Surfy plays a key role by serving as an essential digital repository throughout a building’s lifecycle. By facilitating space planning, dynamic employee allocation, and security management through precise digital plans, Surfy ensures optimal infrastructure operation. Linking buildings to IoT, it provides insights on occupancy rates, energy consumption, and more, enabling proactive and sustainable management. This data and functionality centralisation makes Surfy a strategic tool for high-performing and resilient work environments, directly aligning with organisations’ evolving needs.

BIM challenges and prospects

Initial cost and adoption

One major challenge in BIM adoption is initial costs, including software acquisition, equipment upgrades, and team training. For many firms, this investment poses a barrier, though it can be recouped in the medium term. A Deloitte (2020) analysis indicates that BIM ROI often appears within the first three years due to error reduction, timeline optimisation, and better resource management. Solutions like BIMcloud facilitate collaborative, centralised management to offset these costs.

Interoperability and collaboration

Collaboration among BIM project stakeholders depends on the compatibility of exchanged systems and data. While standards like Industry Foundation Classes (IFC) improve interoperability, adoption remains uneven. Users may encounter issues when specific systems or software fail to communicate effectively, potentially delaying and complicating projects. Successful BIM projects require careful digital architecture planning and data-sharing processes for seamless collaboration. IFC Viewer is a useful tool for checking and visualising files using this standard.

Training and resistance to change

BIM entails significant changes in organisational culture and traditional working methods. Successful integration requires training teams on new tools and management processes. However, resistance to change is common among professionals, which can slow adoption. According to a BuildingSMART International (2021) survey, nearly 45% of firms cite a lack of internal skills as a barrier to successful implementation. BIM 360 offers tailored training modules and collaborative tools to help overcome these obstacles.

Conclusion

BIM represents a major transformation in the construction industry, offering gains in accuracy, efficiency, and sustainability. Despite adoption challenges, studies show that BIM improves collaboration, reduces costs, and optimises every stage of a building’s lifecycle, affirming its essential role in the sector’s future.
