Building Information Modeling (BIM)

We use BIM as a verb or an adjective phrase to describe tools, processes and technologies that are facilitated by digital, machine-readable documentation about a building, its performance, its planning, its construction and later its operation. Therefore BIM describes an activity, not an object. To describe the result of the modeling activity, we use the term "building information model," or more simply "building model" in full. Eastman,(586)

Building Model (or Building Object Model)
This consists of a digital database of a particular building that contains information about its objects. This may include its geometry (generally defined by parametric rules), its performance, its planning, its construction and later its operation. A Revitmodel and a Digital Projectmodel of a building are examples of building models. "Building model" can be considered the next generation replacement for "construction drawings," or "architectural drawings." Downstream in the processs, the term "fabrication model" is already in common use as a replacement for "shop drawings." Eastman, (587)

Building Information model is a virtual representation of a building, potentially containing all the information required to construct the building, using computers and software. The term generally refers both to the model(s) representing the physical characteristics of the project and to all the information contained in and attached to components of these models. When BIM is used in a sentence, it will depend on the context whether it means building information model of building information modeling. A BIM may include any of or all the 2D, 3D, 4D (time element-scheduling), 5D (cost information), or nD (energy, sustainability, facilities management, etc., information) representations of a project.

Building Information modeling is the act of creating and/or using a BIM. Kymmell, (250)

Building Information Model:

  1. To manage project information including data creation and the iterative process of exchanging data through the built environment value network: BIM includes processes by which the right information is made available to the right erson at the right time. BIM adds intelligence to project data to allow data to be interpreted correctly removing attribution errors and assumptions.
  2. To create or work with a single archive where every item is described once: Graphical representations- drawings and non-graphical documents-specifications, schedules, and other data are included. Changes are made to any item inone place and changes flow through the system.
  3. To represesnt physical and functional characteristics of an sset digitally in a reliabel archive of asset information, from conception onward: without complying with the National CAD Standard adn Industry Foundation Classes, it is proprietary, not interoperable and not BIM. Jernigan, (317)

BIM is a relatively recent switch in design and documentation methodology in the design and construction industries. BIM is information about the entire building and a complete set of design documents stored in an integrated database. All the information is parametric and thereby interconnected. Any changes to an object within the model are instantly reflected throughout the rest of the project in all views. A BIM model contains the building\'s actual constructions and assemblies rather than a two-demensional representation of the building that is commonly found in CAD-based drawings. BIM is defined as the creation and use of coordinated, consistent, computable information about a building project in design-parametric information used for design decision making, production of high-quality construction documents, prediction of building performance, cost estimating, and construction planning. Krygiel, (26-27)

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.

Building Information Modeling-Process
A collection of defined model uses, workflows, and modeling methods used to achieve specific, repeatable, and reliable information results from the model. Modeling methods affect the quality of the information generated from the model. When and why a model is used and shared impacts the effective and efficient use of BIM for desired project outcomes and decision support.

BIM is the process of generating and managing building data during the life cycle of a building. BIM uses three-dimensional (3D), real-time, dynamic building modeling software. BIM includes building geometry, spatial relationships, geographic information, and quantities and properties of building components. BIM can include four-dimensional (4D) simulations to see how part or all of the facility is intended to be built and 5D capability for model-based
