Building Information Modelling (BIM)

BIM goes beyond traditional 2D drawings and blueprints, as it encompasses a 3D model with intelligent objects that power design and specifications.

Building Information Modelling enhances the efficiency and effectiveness of the construction and management of buildings and infrastructure. It helps to reduce errors, minimise waste, improve collaboration and deliver projects more cost-effectively and with higher quality.

Over the last decade or so, BIM has, understandably but incorrectly, become interchangeable with the wider digital adoption agenda for the built environment. After much work over a number of years, there is now an accepted definition of BIM enshrined in the international standards.
The key components and characteristics of BIM include:

• 3D models that represent the physical and functional characteristics of the project’s components, such as walls, doors, windows, structural elements, HVAC systems, plumbing and more.
• Intelligent information such as material specifications, dimensions, performance data and maintenance requirements.
• Collaboration and coordination so all stakeholders can work together on the same model, share information and detect any potential issues early in the project.
• Lifecycle information management from the initial design through to construction, operation and even demolition. The data accumulated during the lifecycle can be valuable for facilities management and future renovations.
• Data interoperability so those involved in the project can exchange data seamlessly even if they are using different software packages.
• Accurate quantities and cost estimation thanks to intelligent objects and connected data.
• Simulate and analyse energy performance and sustainability aspects of a building.

Building Information Modelling ISO19650
“The use of a shared digital representation of a built asset to facilitate design, construction and operation processes to form a reliable basis for decisions”

ISO 19650 recommends concepts and principles for business processes across the built environment for using BIM during the life cycle of built assets from procurement through to asset management. Rather than attempting to redefine or improve upon this internationally agreed definition, it is better to direct people who would like to know more about BIM to the UK BIM Framework.

The UK BIM Framework encourages the use of Construction Operations Building Information Exchange (COBie) and Industry Foundation Classes (IFC) as standard formats for data exchange to enable effective collaboration across the supply chain.

To implement BIM effectively during the operational phase of a building’s life cycle, the government has mandated Government Soft Landings (GSL). This ensures better asset management and performance by engaging construction and operational teams in the handover process.

The UK BIM Mandate announcement set a lot of actions in motion and is still a driving force today for keeping the UK at the forefront of the international BIM community.
