Creating BIMs makes planning, designing and managing the construction of building projects more efficient. By creating a BIM model, architects and structural engineers can quickly cycle through a range of possible designs. This allows them to seek out the best solution, based on a variety of factors: material cost, usability, energy efficiency, etc.
Traditionally, architectural design relied on 2D technical drawings. This frequently resulted in misinterpretation and inconsistency. 3D models offer an additional dimension to help everyone involved in the project to better understand the space and the relationship between various building elements.
BIM offers an additional layer of data to a 3D model. BIM allows each specialist to add their own data to the model. By including all Levels of Development in the same model (e.g. architectural, structural and MEP) it’s easier to plan and coordinate the project, and highlight any clashes and inconsistencies.
Another advantage is that it is easy to quickly add annotations to BIM drawings because the data you need is already contained within the geometry.
What is the difference between BIM and CAD?
CAD (Computer Aided Design or Computer Aided Drafting) is, quite simply, the use of a computer to help within the design process. It is also common to refer to any software package used for design as “CAD”.
Drawings created with a CAD software package don’t necessarily contain additional data regarding material, cost, weight, etc. CAD can just be “dumb” geometry.
Building information models are CAD models that also contain building-specific data. This makes things like analysis and data extraction easier. This information includes everything from geospatial information to item quantities. It aids the design process from initial planning, to construction and beyond.
What is BIM used for?
BIM is used to design and document buildings and structures: houses, factories, apartments, offices, plants, etc.
Building information models are used for analysis, to cycle through a variety of different design solutions, to create renders for clients, and to extract 2D section plans and documentation for construction and site workers.
A Building Information Model can even be used for simulation analysis, such as, energy efficiency, earthquake stability and general safety. In addition, a BIM model can be used both during and after construction.
What is the process of BIM?
The process of creating a building information model is not at all complicated. It is very much like the process of any building modeling. However, when BIM is used, the 3D model created has additional data attached.
