What is BIM?

BIM  refers to the implementation and adoption of Building Information Modeling (BIM) standards, practices, and technologies. BIM is a process that involves the generation and management of digital representations of physical and functional characteristics of places. It is widely used in the construction and architecture industries to improve collaboration, reduce errors, and enhance efficiency throughout the lifecycle of a building or infrastructure project.

Key Aspects of BIM

1 

Government Mandate and Standards:

  • BIM Level 2 Mandate: The UK government has mandated the use of BIM Level 2 for all centrally procured public projects since April 2016. This mandate aims to improve efficiency and reduce costs in public sector construction.

​

  • BSI Standards: The British Standards Institution (BSI) has developed a series of standards for BIM, including BS EN ISO 19650, which outlines the organization and digitization of information about buildings and civil engineering works, including building information modelling.​

BIM Levels:

  • BIM Level 0: Involves unmanaged CAD (Computer-Aided Design) with paper or electronic paper drawings.

​

  • BIM Level 1: Managed CAD in 2D or 3D with a collaboration tool providing a common data environment, but without full collaboration.

​

  • BIM Level 2: Collaborative working where all parties use their own 3D CAD models, but not necessarily working on a single, shared model. This level includes defined standards and collaborative processes.

​

  • BIM Level 3: A fully integrated and collaborative process, often referred to as iBIM or integrated BIM, involving a single shared project model.

COBie (Construction Operations Building Information Exchange):

  • COBie is a standard for the exchange of information about building assets, which is an integral part of the UK’s BIM Level 2 requirements. It helps in managing asset data during the project lifecycle.

4

Digital Construction Initiatives:

  • UK BIM Framework: The UK BIM Framework provides guidance on the implementation of BIM across projects and organizations in the UK, supporting the adoption of standards such as ISO 19650.

​

  • Centre for Digital Built Britain (CDBB): A partnership between the UK Government and the University of Cambridge, CDBB promotes digital transformation in the built environment.

Industry Benefits:

  • Improved Collaboration: BIM fosters better collaboration among project stakeholders through shared digital models.

​

  • Cost Efficiency: By reducing errors and rework, BIM helps in lowering overall project costs.

​

  • Enhanced Quality and Performance: BIM ensures better quality control and enhances the performance of buildings and infrastructure.

​

  • Sustainability: BIM supports sustainable construction practices by facilitating energy-efficient designs and reducing waste.

Training and Certification:

  • Various training programs and certifications are available in the UK to support professionals in adopting and effectively using BIM. Organizations like the RICS (Royal Institution of Chartered Surveyors) and CIAT (Chartered Institute of Architectural Technologists) offer BIM-related courses and certifications.

Conclusion

BIM in the UK represents a structured approach to managing building information throughout the lifecycle of a project. With government mandates, established standards, and a focus on digital transformation, BIM has become a critical component of the construction and architecture industries in the UK. The adoption of BIM practices leads to improved efficiency, better collaboration, and enhanced project outcomes, aligning with the goals of modernizing the construction sector and promoting sustainable practices.
