Dimensions
Building Information Modeling (BIM) helps create and manage information models in a custom data environment that contains both graphical and non-graphical information (Ingibjörg Birna Kjartansdóttir). The information associated with the 3D Model increases as the project progress increases.
The simplest way to explain BIM dimensions is that they are further details or pieces of information added to a model to help the project team better understand the model (Hamil, 2021). They are the specific ways in which different data types are integrated into an information model. You get a better picture of the project by adding more dimensions of details, such as how it will be organized, its cost, and how it should be maintained.
It should be noted that BIM Dimensions are different from the BIM Level of Development. The level of development standards shows the extent to which a 3D model’s geometry, specs, and associated information can be relied on by the team members. On the other hand, BIM Dimensions are details or further information stored within a model, like its cost, time, and other factors.


BIM 3D
-
Real-time interface: Gives better visualization without visiting the site.
-
Get well-organized designs: Industry-ready 3D models.
-
Cost-effective: Save millions of bucks and tons of hours in rework.
-
More power: Gives you more control as an Engineer.
-
Easy circulation: Send models across and communicate better.
BIM 4D
The fourth dimension of BIM (BIM 4D) allows us to analyze and control construction times. In this way, the designers can coordinate/plan the activities related to the building construction process.
4D modeling allows designers to see the temporal progress of activities from the design phase, in order to obtain important advantages such as time optimization, a priori error detection and planning.


BIM 5D
BIM 5D is a way of presenting the physical and functional characteristics of any project in 5 dimensions. It allows us to add data about cost estimates precisely, in a visual information model.

BIM 6D
BIM 6D is the BIM dimension that adds sustainability information to the geometric model of the building. The concept of sustainability can be declined into: environmental sustainability – ability to value the environment. economic sustainability: ability to generate income and employment.

BIM 7D
Asset Life Cycle Management (Facility Management). Dimension that involves the use of models in order to anticipate or carry out maintenance and operations activities and processes throughout the life cycle of the building or infrastructure.
