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.
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.
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.

“BIM provides a common environment for all information defining a building, facility or asset, together with its common parts and activities.This includes building shape, design and construction time, costs, physical performance, logistics and more. More importantly, the information relates to the intended objects (components) and processes, rather than relating to the appearance and presentation of documents and drawings.More traditional 2D or 3D drawings may well be outputs of BIM, however, instead of generating in the conventional way ie. as individual drawings, could all be produced directly from the model as a “view” of the required information.” – RICS

“The future of BIM modeling is to expand the information model to include more of the life cycle phases (ie: real property commerce, maintenance and operations, environmental simulation, etc.), to standardize life cycle process definitions and associated exchanges of information, and to standardize information content so that meanings and granularity are clear and consistent.” – NIBS, 6/25/2012
“Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle. Typically it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. The process produces the Building Information Model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components.” – Free Dictionary, 6/25/2011

“A Building Information Model (BIM) is a digital representation of physical and functional characteristics of a facility. As such it serves as ashared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM process to support and reflect the roles of that stakeholder. The BIM is a shared digital representation founded on open standards for interoperability.” – NIBS, buildingSMART, NIBS, 2006

BIM and Cloud technologies/processes will redefine the relationships between all construction professionals.
BIM is the life-cycle management of the built environment supported by digital technology. While 3d visualization, aka Revit, Archicad, Bentley, et al is a valuable component of BIM it is neither the primary component, or necessarily a requisite component. These 3d visualization tools and their suppliers have primarily targeted architects and designers. Why is that? It’s simple, 3d visualization helps in the visual design and “selling” of structures. When combined with MEP, it also can save money relative to crash/collision detection.
The true value of BIM, however, lies within business management and process change/adaptation. The integration of previously disparate silos of construction and facility management information and processes into a collaborative, transparent environment is what BIM offers.
How do we get there? Simple really, the combination of BIM with CLOUD technology will result in disruptive, positive change. Affordable, scalable technology is now available to embed robust business processes.
For example, Integrated Project Delivery (IPD), and Job Order Contracting (JOC), the latter being IPD for facility renovation, repair, sustainability and minor new construction, are both efficient, proven construction delivery methods. The are now both available embedded within technologies to support the collaborative needed of Owners, Contractors, AEs, BPMs (business product manufactures), and the relevant other Community members.
The linking of efficient construction delivery methods like IPD and JOC, with CPMS, CMMS, CAFM, BAS, GIS… to name a few… has already begun.
Valuable information On-Demand to enable efficient construction and facility management is BIM… part technology, part process, 100% collaborative.
Terms of equal import to BIM? ” Adaptive Project Delivery” and “Adaptive Construction Management”.

“The NBIMS Initiative categorizes the Building Information Model (BIM) three ways, as product, as an IT enabled, open standards based deliverable, a collaborative process, and a facility
lifecycle management requirement.”
I personally view BIM as a collaborative, cradle-to-grave facility management process, deployed, scaled, supported and consistently applied by technology (products).
Whether there will be a single “product” is questionable. 3d Object-oriented tools such as Revit, Archicad, et al are not BIM.
Also the term “Model” has created a major problem, as again, many assume a Revit or Archicadm et al, “model” is BIM…
“Management” aka Building Information Management vs. Building Information Model, is arguably the best single “edit” one could make to the above NBIMS categorization of BIM.
As an business sector, we need to “get out of the weeds” and make some significant business process and cultural changes across all segments of Contruction, Engineering, Architecture, Operations, and Maintenance of faciliteis and infrastructure.
BIM is not stagnating due to the economy, it is stagnating due to an overall lack of understand relative to facility lifecycle management and its associated core requirements:
portfolio definition and association with an organization’s mission,
associated physical and functional conditions,
costs and cost engineering,
efficient project / contract delivery methods,
and the associated transparent collaborative processes.

BIM, by definition, is facility life-cycle managment enabled by technology.
Multiple knowledge domains must be merged to accomplish “Big BIM” including CPMS (capital planning and management systems), CMMS (computerized maintenance management systems), CAFM (computer-aided facility management – space planning), IPD/JOC (Integrated Project Delivery and Job Order Contracting), and BAS (building automation systems), GIS (geographic information systems).
Owners, Contactors, AEs, Business Product Manufacturers, Oversight Groups, Building Users, and the Community at large all have respective roles relative to BIM.
BIM starts with, and its success relies upon; strategy, and process, standardized terms/definitions/information, and a technology backbone to enable cost effective implementation, scalability, information reuse, and ongoing decision support.
Integrated Project Delivery, and Job Order Contracting (the latter a form of IPD specifically for facility renovation, repair, and sustainability) are construction devliery methods, processes, that are well suited for integration with BIM in lieu of traditional design-bid-build or design-build.

BIM can be a 3-D visual model, a model with associated design, as-built, and life-cycle information, and a business process.
All are important, however, BIM will change the basic fabric of the AEC industry.
What is BIM?
( Source: BSI via http://www.4clicks.com )
BIM is the process of generating and managing information about a building during its entire life cycle. BIM is a suite of technologies and processes that integrate to form the ‘system’ at the heart of which is a component-based 3D representation of each building element. This replaces traditional design tools currently in use.
Each component is generated from a product library and has embedded information about the product and its placement, material, specification, fire rating, U-value, fittings, finishes, costs, ‘carbon content’ and any special requirements, which is stored in the system.
Key Benefits of BIM:
- Early cost certainty
- Reduced delivery costs
- Reduced operational costs
- Green performance
- Reduced risk
- Predictable planning.
Who should use BIM?
BIM is for firms in all parts of the architectural, engineering and construction industry, whatever their sizes, as well as clients who may be planning to require their supply chain to use BIM tools.
It is especially useful for:
- Structural engineers
- Building Services Engineers
- Cost consultants
