Use of a shared digital representation of a built asset to facilitate design, construction and operation processes to form a reliable basis for decisions - ISO 19650-1.2019
Building Information Modeling (BIM) is a digital representation of the 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 - National Institute of Building Science (NIBS) / US National Building Information Model Standard Project Committee
BIM or Building Information Modelling is a process for creating and managing information on a construction project across the project lifecycle.
A rich information model, consisting of potentially multiple data sources, elements of which can be shared across all stakeholders and be maintained across the life of a building from inception to recycling - National Building Specification (NBS)
Building Information Modelling is a 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 - RIBA, CPIC
Building Information Modeling (BIM) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct and manage buildings and infrastructure - Autodesk
The base of BIM (Building Information Model) is a digital 3D model of the building. It consists of walls, slabs, roofs, doors, windows and such, just like the real building.
In BIM we also assign invisible data (metadata) to the digital elements of the model, such as structural function, fire resistance value, acoustic performance value, thermal transmittance, price, weight, product information, etc. - Graphisoft
BIM is a digital form of construction and asset operations. It brings together technology, process improvements and digital information to radically improve client and project outcomes and asset operations. BIM is a strategic enabler for improving decision making for both buildings and public infrastructure assets across the whole lifecycle.
Building Information Modelling (BIM) is at the centre of a digital transformation of the construction sector and the built environment. Governments and public procurers across Europe and around the world are recognising the value of BIM as a strategic enabler for cost, quality and policy goals - EU BIM handbook

Information is the key in BIM that supports the knowledge intensive construction management activities and tasks
In addition to 2D and 3D computer-aided design (CAD) modelling, there is also 4D, 5D, 6D and 7D.
3D refers to three-dimensional geometry.
4D refers to construction sequencing information that includes the three spatial dimensions and an additional dimension of time.
5D includes 4D plus “cost”. It integrates design with the estimating and scheduling of costs including labour and productivity rates.
6D and 7D include aspects like sustainability and facility management and other concepts like the Internet of Things (IoT).

The AEC (Architecture, Engineering and Construction) industry has introduced various changes to ease the workflow and processes, such as CAD (Computer-Aided Design) and CAD software that integrates BIM.
