Definition of BIM – Building Information Modeling – NIBS, AGC, NBIMS, smartBUILDING Alliance, ISO, RICS


Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.  – NBIMS – National BIM Standard – United States

Building Information Modeling is the development and use of a computer software model to simulate the construction and operation of a facility.

The resulting model, a Building Information Model, is a data-rich, object-oriented, intelligent and parametric digital representation of the facility, from which views and data appropriate to various users’ needs can be extracted and analyzed to generate information that can be used to make decisions and improve the process of delivering the facility.

The process of using BIM models to improve the planning, design and construction process is increasingly being referred to as Virtual Design and Construction (VDC). – AGC

1. Building information Modeling: A BUSINESS PROCESS for generating and leveraging building data to design, construct, and operate the building during its lifecycle. BIM allows all stakeholders to have access to the same information at the same time through interoperability between technology platforms.

2. Building Information Model: The DIGITAL REPRESENTATION of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility, forming a reliable basis for decisions during its life-cycle from inception onwards.

3. Building Information Management: The ORGANIZATION and CONTROL of the business process by utilizing the information in the digital prototype to effect the sharing of information over the entire life-cycle of an asset. The benefits include centralized and visual communication, early exploration of options, sustainability, efficient design, integration of disciplines, site control, as-built documentation, etc. – effectively developing an asset lifecycle process and model from conception to final retirement.  – NIBS

Building Information Modelling (BIM) is the process of generating and managing data about the building, during its life cycle. Typically BIM uses three-dimensional, real-time, dynamic building modelling software to increase productivity in the design and construction stages. – NBS

Building Information Modelling (BIM) is a new approach to being able to describe and display the information required for the design, construction and operation of constructed facilities. It is able to bring together the different threads of information used in construction into a single operating environment thus reducing, and often eliminating, the need for the many different types of paper document currently in use. To use BIM effectively however, and for the benefits of its use to be released, the quality of communication between the different participants in the construction process needs to be improved.
If the information needed is available when it is needed, and the quality of that information is appropriate, then the construction process can be improved. For this to happen, there must be a common understanding of building processes and of the information that is needed for and results from their execution. The Industry Foundation Classes (IFC) provides a comprehensive reference to the totality of information within the lifecycle of a constructed facility. It has been created as an integrated whole in response to the identification of business needs expressed by the international building construction community. It does not contain a comprehensive reference to individual processes within building construction.
The case for a comprehensive reference to processes in building construction is clear and compelling. By integrating information with the process, the value of such a reference is greatly enhanced and it becomes a key tool in really delivering the benefits of BIM.

-buildingSMART

A shared digital representation of physical and functional characteristics of any built object including buildings, bridges, roads, process plants etc. forming a reliable basis for decisions.

– ISO

Building information modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of a facility. The resulting building information models become shared knowledge resources to support decision-making about a facility from earliest conceptual stages, through design and construction, through its operational life and eventual demolition.

– Wikipedia

“Building Information Modelling is digital representation of physical and functional characteristics of a facility creating a shared knowledge resource for information about it forming a reliable basis for decisions during its life cycle, from earliest conception to demolition.”
