BIM is a short form that stands for building information modelling process. But this acronym includes many more definitions and processes which briefly explain the diversified functionalities of BIM. Tom Payne, the Co-Founder of B1M, has listed down most crucial top 10 acronyms which will facilitate BIM users to learn the fundamentals of BIM quickly and easily.
BIM: (Building Information Modelling) Building Information Modelling is a new way of approaching the design and the documentation of building process. BIM collects all the building data and organized them into a model based database for digital reprentation.
IFC: Industry Foundation Classes (IFC) denote the open and neutral data format for open BIM. IFC is developed by BuildingSMART. IFC provides the internationally recognized standard for exchanging data in a broader way. It makes the difference between BIM and open BIM.
LOD: (Level of Detail) LOD identifies the existence of graphical or 3D data inside an information model to some specific point of a project. Basically LOD is applied to geometry detail only. The complexity of a 3D object representation is decreased in the account of LOD. In levels of definition, both the terms like Levels of Detail and Levels of Information are included.
LOI: Level of Information alias the amount of non-graphical data exist in an information model at some particular stage. There are four types of BIM levels Level 0 BIM, Level 1 BIM, Level 2 BIM, Level 3 BIM.
MIDP: It refers to (Master Information Delivery Plan) and it is originated out of the BIM implementation plan. It is prepared to find out what information should be transmitted and in what format as well as the timescales and who will be responsible for implementation. It is the primary plan for the preparation of the project. MIDP involves schedules, specifications or other 2D documentation.
BIM EP refers to BIM Execution Plan: It is one of the most important elements of any successful BIM project. This document is distributed & abided by all the project stakeholders. It defines how all the project stakeholders will work in tandem for conveying the needs of the EIRS. It is a plan prepared by the suppliers to explain how the information modelling aspects of a project will be carried out. The intent of this BIM Execution Plan is to provide a framework that will let the owner, architect, engineers, and construction manager to deploy BIM technology and best practices on any project faster and more cost-effectively.
EIR: EIR refers to Employer’s Information Requirements. At the initial stage of a project, Clients or Employers outline the required information in this document. This document will be helpful for clients or employers to undertake decision concerning their requirements at the final stage of the project as well as their requirements at the time of disposition to optimize the functioning of their new asset. With this document, the project teams can get clear ideas regarding necessity of graphical and non-graphical information.
PIM & AIM: Inside a BIM progression, Project Information Model is created with precisely developed and perfectly connected both graphical and non-graphical information data. The information model is known as the “Project Information Model” or PIM throughout the delivery stage, and an “Asset Information Model” or at the time of completion & disposition of a project.
CDE: Common Data Environment denotes a cloud supported common digital space accessible by project team online. The Common Data Environment (CDE) acts like a single source information hubfor the project that facilitates the team members to accumulate, control and distribute documentation containing the graphical model and non-graphical data for the whole project team.
PAS- 1192: Publically Available Specification 1192 specifically designed for the delivery stage of construction project that is managed through BIM. In this stage most of the graphical data, non-graphical data and documents are gathered from design and construction activities. Organizations can use a PAS to improve productivity, increase efficiency, reduce costs, maintain quality or speed up innovation.
