BIM (Building Information Modelling) is an information management system used throughout construction to enable collaboration and communication among multi-disciplinary teams in digital environments. According to a study by the International Federation of Consulting Engineers (IFS), BIM has been successfully implemented in various construction projects worldwide, resulting in improved collaboration and reduced errors.
Key Characteristics of BIM
BIM is more than just creating 3D models of buildings—it allows you to share information, collaborate with other people, and create digital representations of physical and functional characteristics of places. This enables architects to design a sustainable building to pass the Green Mark awards and to achieve the Green Mark.
BIM models are created using software and hardware to generate digital representations of the physical and functional characteristics of places. By leveraging this technology, engineers and architects can analyze and optimize building performance, reducing the overall cost and environmental impact.
BIM models are created by manufacturers and then placed into a central online library according to the relevant product classification standard (often known as classification codes). The Association for Standards Development (ASC) promotes an international standard for the implementation of codes and classes.
Implementation Benefits of BIM
Overall, BIM offers numerous benefits to the construction industry. It enhances collaboration and communication among teams, allows for increased efficiency, and improves the accuracy of construction projects.
Integrating BIM models from various sources also allows for efficient inventory management and enhanced decision-making.
The Building Information Modelling (BIM) model is built from various digital components, called objects, like walls, doors, windows, and other 3D elements.
Objects can be used to represent physical or functional characteristics of a building, such as doors, windows, or roofing materials. They are created by manufacturers and then placed into a central online library, according to the relevant product classification standard. This library allows architects, engineers, and contractors to access and reuse these objects, reducing errors and increasing efficiency. By using standardized objects, BIM models can be shared and accessed by multiple stakeholders, facilitating collaboration and improving project outcomes.
A single object can be used many times within the same BIM model, creating a sense of realism within the project.
A single BIM object can be used many times within the same BIM model, and this is a key factor in creating a sense of realism. A particular building component, such as a door, may be used to represent several buildings on site. For example, an office block might use the same door for each office door in the model. Although each space is unique, the door remains identical, so it can be used over and over again without needing to change anything about it or create multiple doors from scratch. This approach allows for a high level of detail and accuracy in the building model, creating a more realistic and immersive environment.
When it comes to collaboration in BIM, the ability to reuse objects is a game-changer. According to a study by Autodesk, the number of objects in a model has a significant impact on its complexity and the time required to analyze it. By reusing objects, teams can save time and reduce errors, while also improving the overall quality of their models.
So, what does this mean for collaboration? In short, everything! The ability to reuse objects means that once you’ve created something in your own project team’s private model, anyone else working on another project can take advantage of it too, even if they’re using a different software package like Revit or Vectorworks Designer. This allows teams to share knowledge and expertise across different projects, leading to better outcomes and increased efficiency.
Each object contains data, or parameters, as well as geometric information required by the modelling software
Each object in a BIM model contains data, or parameters, as well as geometric information required by the modelling software. This information can include characteristics such as size, shape, and orientation, as well as properties like material type and color. The type of objects included in a model is determined by its purpose, such as building a house, which may require walls, windows, and doors, but not furniture.
When creating a 3D model for analysis purposes, it’s essential to include only the objects necessary for the analysis. According to a research paper by the National Institute of Building Sciences, this can help reduce the complexity of the model and make it more efficient to analyze. For example, if the intent is to create a model for energy analysis, it’s only necessary to include objects with geometric information, such as walls and ceilings, and define their properties using parameters like distance from other elements and size.
These parameters can be used to define the properties of elements such as walls, ceilings, and floors. For instance, you can define how far away from other elements these elements will be placed, how long they are, what color they have, and other characteristics. By using parameters, teams can create a more accurate and detailed model that meets their specific analysis needs.
Objects in a BIM model also include relationship data defining how they relate to other objects within the model.
According to the Building Information Modelling (BIM) Foundation, an International Standard BIMSA (BS 8587:2012), objects in a BIM model are more than just physical items; they also contain powerful data about their relationships to other objects within the model. For example, an object’s location in a building might be defined by its relationship to other objects, such as walls and doors.
The objects are created by manufacturers and then placed into a central online library according to the relevant product classification standard (often known as classification codes).
The objects are created by manufacturers and then placed into a central online library according to the relevant product classification standard (often known as classification codes), enhancing searchability and accessibility for users. This centralizer technique according to the rules stated by Tomei & Zahiri classifies objects efficiently, providing efficient search capabilities by enabling users to reach data based on provided keywords.
