05 # Building Information Modeling (BIM) & its basic Terminology
By Avinash Singh on June 02nd , 2020
In this blog I have find some basic Building Information Modeling (BIM) Terminology, helpful for those just beginning with BIM.
Building Information Modeling
BIM is a collaborative visual representation of a built environment that promotes the planning, installation and execution of processes and offers a consistent framework for decision taking.
Layout of Construction Details
The BIM model is an entity – a 3D-based digital model that includes knowledge and data over the entire life cycle of a constructed product.
3D - 3D object-based modeling that includes non-graphical data.
4D - 4D applies to applying period details to the 3D model.
5D - 5D applies to the addition of Cost data to a 3D model
6D - 6D refers to the use of rich-data models for facility management
Level 0 - In Level 0, 2D simple CAD objects are used to create 2D drawings, communication is done through paper and basic prints. There's no collaboration.
Level 1 - In Level 1, 3D basic 3D CAD structures are used to build 3D models and 2D sketches, and data is exchanged via the General Data environment.
Level 2 - In Level 2, 3D artifacts containing knowledge and libraries are used in the BIM framework.
Level 3 - The data in Level 3 is transparent and accessible to all stakeholders in the Shared Software Setting. Cooperation is combined with sophisticated modeling and automated project execution. The principle of life cycle management may be introduced at this point. Collaboration is mixed and 4D and 5D may be formed at this stage.
BIM Object - A BIM model is a graphical image of a particular entity, with extensive details about the structure and physical features of the model.
Level of Development (LOD) – This Specification is a guide that allows experts in the AEC industry to define and express the quality and functionality of the Building Information Models at various construction stages with a broad degree of consistency.
Asset information model (AIM) - The knowledge model corresponding to the operating process. It includes the details required to help the control of funds.
Project information model (PIM) - Knowledge Layout for the distribution process. The PIM model is being built during the project design and development phase.
IFC- IFC is an open industry base class model built by Building Smart. The interoperability approach between various software applications is called.
BIM Execution Plan (BEP) – BEP is a document designed by vendors to clarify how the knowledge processing elements of the project should be applied.
Exchange Information Requirements (EIR) - The specifications of the EIR shall specify the details needed by the contractor, both from its own internal staff and from the vendors, for the production of the project and for the activity of the completed built product.
Common Data environment (CDE) - CDE is a central place for each project or resources for the compilation, maintenance and exchange of project data / information.
COBie - Construction Operations Building Information Exchange (COBie) is a non-proprietary multinational data system used to exchange non-graphic details for building management.
RACI - RACI is a compiled abbreviation to identify participants or stakeholders (on a project), as Responsible for (R), need to Authorize (A), those who can Contribute to (C) or are to be kept Informed (I) about a project activity.
