In the construction industry, there is still a major confusion between Building Information Modeling and Revit, where BIM is considered to be a piece of software such as Revit. However; the fact is that Revit is one of the BIM tools available and is widely used for the creation of the 3D digital BIM model. See also How BIM and digitalization is transforming construction.
BIM is a process, a methodology and Revit is a single application built for Building Information Modeling with features for the three main disciplines of the AEC industry, (Architectural, MEP- Mechanical, Electrical and Plumbing, Structural engineering).
Definitions
According to the UK BIM Task Group: BIM is essentially value-creating collaboration through the entire life-cycle of an asset, underpinned by the creation, collation and exchange of shared three-dimensional (3D) models and intelligent, structured data attached to them.
According to the BIM dictionary: Building Information Modelling (BIM) is a set of technologies, processes and policies enabling multiple stakeholders to collaboratively design, construct and operate a Facility in a virtual space.
According to NBS: BIM or Building Information Modeling is a process for creating and managing information on a construction project across the project lifecycle. One of the key outputs of this process is the Building Information Model, the digital description of every aspect of the built asset. This model draws on information assembled collaboratively and updated at key stages of a project. Creating a digital Building Information Model enables those who interact with the building to optimize their actions, resulting in a greater whole-life value for the asset.
According to Autodesk: Autodesk® Revit® software is specifically built for Building Information Modeling (BIM), helping building professionals design, build, and maintain higher-quality, more energy-efficient buildings.
According to PAS 1192-2:2013: BIM is the process of designing, constructing or operating a building or infrastructure asset using electronic object-oriented information.
According to ISO 19650: BIM is about obtaining benefits through better specification and delivery of suitable and correct amounts of data concerning the design, construction, operation and maintenance of buildings and infrastructure, using appropriate technologies.

Why BIM is not just REVIT
There is no singular “#BIM tool” that can accommodate all the required modelling needs for a project. People from a range of disciplines are working together and coordination is necessary to complete a successful full BIM project. In BIM you should work with a BIM Execution plan, a CDE, (Common Data Environment), follow a LOD strategy, (amount of information inserted on each project stage), create Cobie Sheets, work with SMPs, (Standards, Methods and Procedures), Clash reports and 4D Construction Sequencing. In the BIM process, the Employer's requirements are captured and documented, while additional information management roles emerge in the workplace to ensure the approval and coordination of the information of the digital model.

BIM is more than just #Revit, and this needs to be continually communicated. Revit's digital model creates a powerful database consisting of information at all stages of a construction project. A digital building is created using 3D intelligent objects with stored information that can be used to successfully time and cost management for the whole lifecycle of a project. Revit uses model-building components to analyze and simulate systems and structures. Revit collaboration tools allow all team members to work in shared models and import, export and link data with commonly used formats. The shared models can be accessed by multiple project contributors at every phase and this results in better coordination and reduced errors and rework. Revit 3D visualization tools provide effective communication between project owners and team members by using models to create high-impact 3D visuals.
Revit is a software that supports BIM information management. Even Autodesk in their site mentions that Revit is BIM software, not just BIM. However, BIM Revit models allow you to:
Work with parametric objects - Each component has parametric qualities.
Quick changes, no repetition- Whenever a change is made to the model the software automatically updates every related component, affecting the whole building model, documentation, details, etc.
Construction documentation- High-quality documentation - automatically produced from the 3D model.
Quantities and Cost estimation - Automatic generation from inserted data.
Coordination - Shared models enable teams to collaborate effectively and reduce conflicts.
3D Visualization - This allows better communication with the client and your team.
Interoperability - Revit imports - exports - links your data with common formats such as IFC.
