In short: BIM, or Building Information Modelling, is a way of creating and managing structured digital information about a built asset throughout a project. A BIM model combines three-dimensional geometry with information linked to model elements, so project participants can understand not only what a building looks like, but also the data connected to its parts.
What does BIM stand for, and what is a BIM model?
BIM stands for Building Information Modelling. It is not a single file type or a piece of design software; it is an information-management approach for built assets. The BIM model is the digital representation through which geometry and structured project information can be connected and viewed together.
A model element can contain more than its shape. Depending on how the model was created and what information was included, an element may also contain data such as dimensions, material properties, identifiers or other technical attributes.
BIM model vs. 3D model
A three-dimensional model can be useful simply because it helps people see a building in space. BIM goes further by connecting the geometry to structured information.
| Aspect | Conventional 3D model | BIM model |
|---|---|---|
| Primary purpose | Visual representation of geometry | Geometry plus structured information management |
| Data behind elements | May be limited or absent | Can include element-level technical information |
| Project coordination | Useful for visual understanding | Can support multidisciplinary coordination when relevant model information is available |
| Use during construction | Mainly visual reference | Can support viewing, coordination, issue context and project decisions |
What construction problems can BIM help solve?
Making complex designs easier to understand
Large buildings can be difficult to interpret from two-dimensional drawings alone, especially for project participants who do not work with technical drawings every day. A three-dimensional model can make spatial relationships easier to understand and can help teams communicate a design before and during construction.
Coordinating information across disciplines
Construction projects bring together architecture, structures, building services and many other disciplines. BIM can provide a shared visual environment in which these disciplines can be reviewed together instead of being interpreted as completely isolated sets of drawings.
Reducing uncertainty and avoidable rework
When teams can review spatial relationships and model information together, potential conflicts may be easier to identify before they turn into site problems. BIM does not eliminate errors by itself, but it can support earlier coordination and better-informed discussions.
How is BIM used during a construction project?
Opening and viewing IFC models
BIM models are no longer limited to specialist design applications. Viewer-based workflows allow project participants to open models without using the original authoring software. IFC is one of the widely used formats for exchanging BIM model information between different systems.
Visualising the project in 3D
Three-dimensional visualisation is one of the most immediately useful aspects of a BIM model. Teams can inspect the building from different viewpoints and understand how spaces, levels and disciplines relate to one another.
Using time and cost information
BIM models can also be connected with information beyond geometry. When scheduling and time-related information is linked to the model, the workflow is commonly described as 4D BIM. When cost-related information is integrated as well, the term 5D BIM is commonly used. The actual value depends on the information that is present and maintained in the model.
How can construction teams benefit from BIM?
- Clearer communication of complex designs and spatial relationships.
- Better coordination between architecture, structure and building-services disciplines.
- More context for construction decisions when relevant model data is available.
- A shared digital reference that can also support inspections, follow-up work and handover documentation.
BIM and task management
A BIM model can also become part of a construction task workflow. Instead of describing a location only with text or a 2D marker, a task can be connected to a point in the model. This gives the responsible team a three-dimensional reference and, where the model contains it, access to technical information around the location.
In myPlan.cloud, Task Management is connected to the BIM viewer, so construction tasks can be created with a location linked to a point in the BIM model.
BIM as a digital information resource after construction
After handover, a well-maintained BIM model can continue to be useful as part of the as-built information set. Its value depends on the accuracy, completeness and maintenance of the information included in the model.
How does myPlan.cloud support BIM-based project work?
Viewing IFC models directly in the browser
In myPlan.cloud, BIM model files can be stored and handled in the Documentation module. When a user opens an IFC file, the BIM viewer is activated and the model appears in the browser. Users can then navigate the model and work with the available model information without starting a separate BIM authoring application.
Connecting model context to construction tasks
myPlan.cloud can also use the BIM model as a location reference for tasks. This allows the model to become part of the practical site workflow rather than remaining only a visual or design reference.
Frequently asked questions about BIM
Is BIM the same as a 3D model?
No. A 3D model represents geometry. A BIM model can also contain structured information connected to model elements.
What is an IFC file?
IFC is a widely used open format for exchanging BIM model information between different software environments.
Do construction teams need BIM authoring software just to view a model?
Not necessarily. BIM viewers can make model information accessible without requiring the original authoring software.
What is 4D BIM?
4D BIM generally refers to linking model information with time or scheduling information.
What is 5D BIM?
5D BIM commonly refers to adding cost-related information to the model-based planning environment.
Can BIM be used for construction task management?
Yes. In myPlan.cloud, tasks can be connected to locations in the BIM model, adding spatial and model-based context to the task workflow.
