COMPARATIVE ANALYSIS OF BIM OVER OTHER DESIGN


Building Information Modeling (BIM) is a digital representation of the physical and functional characteristics of a building or infrastructure. It is a process that involves creating and managing digital models of the physical and functional characteristics of a facility throughout its life cycle. BIM is not a specific design software but rather a collaborative approach to design and construction that uses intelligent 3D models to inform and communicate project decisions. Let's compare BIM with other design. You can click here to know what is BIM.


BIM v/s Traditional 2D
  • Traditional 2D Design:

Relies solely on 2D drawings, such as floor plans and elevations, which may lack detailed information about the building components and systems. In traditional building methods, the design and planning phases are typically separate from the construction process. The architect or engineer creates blueprints and specifications, which are then handed over to the construction team.Traditional building methods can be more costly due to unexpected changes or mistakes.


BIM: BIM goes beyond traditional 2D drawings by creating a 3D model that includes not only geometric information but also data about the components and systems in the building. With BIM, the design and planning phase is integrated into the construction process. The building is modeled in 3D using specialized software, and the construction team can use this model to plan and visualize the entire construction process. BIM can reduce the cost of construction by identifying potential issues before they become problems. The 3D model can help to identify clashes between different systems, such as electrical and plumbing, before construction begins. This can save time and money by preventing the need for rework.


BIM v/s CAD
  • CAD (Computer-Aided Design):

Primarily focuses on creating geometric representations of objects without the same level of intelligence and interconnectedness found in BIM. CAD, on the other hand, is not collaborative and requires each designer to work on their own files. CAD is more focused on the design process.


BIM: BIM incorporates the principles of CAD but extends them by adding intelligence to the elements in the model. BIM models are parametric, meaning that changes to one part of the model automatically update related parts. BIM is collaborative, allowing different stakeholders to work on the same model simultaneously. This makes it easier to coordinate different aspects of a construction project. BIM models are more detailed and accurate than CAD drawings, making it easier to identify potential issues and optimize design decisions. BIM is more focused on the construction process.


BIM v/s 3D modeling
  • 3D Modeling:

3D Modeling: May be limited to creating visual 3D representations without the embedded data and information that BIM provides.When forming a model through 3D modeling, collections of points in three-dimensional space are connected with diverse geometric features (like lines, triangles, curved surfaces, and more). These basic geometric features are the only information stored in 3D modeling software. 3D modeling software also harnesses texturing tools and shaders to create photo realistic 3D models of polygon density, helping to produce realistic structures.


BIM: Involves 3D modeling as a core component, but BIM extends beyond just visual representation by including additional data, such as cost, schedule, and performance information.The main distinguishing factor is that BIM holds precise and detailed data about the structural properties of a building, in addition to basic geometric features. For instance, BIM contains info about structural and electrical systems, wall systems, ventilation, heating, plumbing fixtures, air conditioning, windows, doors, and more. Furthermore, it also contains technical information about each of these fixtures. As an example, from a BIM object of a wall, you can get info about its strength, density, reflectivity, among many other properties.

BIM is a more holistic and collaborative approach to design and construction compared to traditional 2D design, CAD, or standalone 3D modeling. It emphasizes information-rich 3D models that facilitate better decision-making throughout a building's lifecycle.
