Building Information Modeling (BIM) is commonly understood as a shared 3D model of a structure enriched with metadata, like material information. Other dimensions such as time (scheduling), cost, or different levels of operational processes can also be added to BIM, making it a construction phase tool and an important database for the structure’s entire life cycle.
BIM is usually created in the construction planning phase, with multiple BIM software options available for generating models. But what if we want to utilise BIM in later phases of the building’s life cycle without models?
In these cases, the structure is most likely to be digitised by scanning it with sonar or a laser scanner to form a point cloud. These point clouds have been traditionally used for modeling solid 3D reference models and CAD models, requiring a lot of work before they can be used. Could the point cloud itself be the 3D model?
Point cloud as BIM
When modeling the point cloud, we lose information as the geometry of a structure is simplified. Considering this fact, does the modeling actually add any value to the point cloud? Likely not.
Utilising the processed and visualised point cloud as a Building Information Model points in the cloud are grouped into point cloud entities according to the building component, and attributes can be input straight to the 3D point cloud entities.
The point cloud has X, Y, and Z coordinates, is in 3D form, can be divided as objects, and is enriched with attribute information. Pretty much covers the definitions for BIM, doesn’t it?
Smart and interactive asset management
What about sharing the model or remaining BIM dimensions? The interactive use and sharing of 3D data is inherent to BIM and separates it from simple 3D models. When the point cloud is easily accessible, utilising its data throughout the life cycle is more likely. This is where online technologies come into the picture.
User-friendly UI and access to the data through a web browser enable all shareholders to utilise the data in different operations of asset management.
Daily users, not just surveyors, planners, or administrators, can do data accretion. The same data can be used online – without any additional software installations – when making CAD drawings, calculating repair budgets, or even guiding the maintenance crew to the correct location to do their tasks. We have come a long way from simple 3D models.
