BIM stands for Building Information Modeling. Working methodologies and a 3D parametric digital model that contains intelligent and organized data are the core components of BIM. From design to demolition, BIM is the sharing of accurate information throughout the life of a building or infrastructure. The model is a computerized depiction of a building's or infrastructure's physical and functional qualities. BIM is often used as a reference to the actual model (or models), as well. However, the primary definition is focused on the process.
BIM is sometimes thought of as software or technology. That is not accurate. It is more accurately processes or workflows that are followed throughout the design, construction, and use of a structure. BIM, is an inclusive environment facilitating the contributions of the entire project team.

The BIM Execution Plan (BEP) is a crucial document for a project's effective BIM implementation. BEP includes the organization and graphical representation methods for the operation, the processes, models, and uses, according to the project's specificities (i.e., rehabilitation, new, allotment, etc.). The BIM Execution Plan also establishes the responsibilities and accountability of team members, and the technologies that will be utilized on the project. In short, it describes the expectations for BIM use according to the project's specifications

A CDE collects all of the project's shared data and makes it available to all of the participants. The formation of a CDE is a requirement for implementing BIM on a project.

IFC is an open BIM data interchange standard. It can be compared to a BIM PDF. IFC files are a frozen representation of the original material, similar to PDFs. They can be viewed, measured, and used for cost estimation or simulation, butt should not be altered. Because IFC is an open standard, it is constantly evolving.

BCF is an open format, introduced by BuildingSMART, allowing concerns to be communicated between different BIM applications without submitting the entire model each time. The format makes it possible to keep track of issues. It also does not require the user to have licenses of all the software applications (i.e., the Designer can use the BCF that is created in a different software, simply by importing it into the BIM authoring technology).
Project members can collaborate even if they are using different BIMs because it is an open format. They can talk about concerns in a BIM by identifying locations in the models and communicating those places. The structure improves project member collaboration, lowers risks such as missing information, and speeds up the process.

The stages of development are described by the Level of Development (LOD) in BIM. It's a set of guidelines for AEC professionals to efficiently document, communicate, and specify BIM material. LOD is a standard that outlines how a building model's 3D geometry can be developed to various levels of refinement and is used to assess the level of service required. It indicates how much various team members can rely on information regarding a specific component.

EIR (Employer's Information Requirements) is a crucial document in the BIM process, as defined by PAS1192- 2 as a "pre-tender document setting out the information to be delivered, as well as the standards and processes to be adopted by the supplier as part of the project delivery process." As a result, it's a good place for clients to start while working on BIM projects. The Employer's Information Requirements document gives detailed guidelines on how to complete a construction project.

Also called middleware, a Building Operating System (BOS) establishes a bridge between the building equipment and external applications. The objective of BOS is to hide the building's complexity while allowing easy access to data from the equipment. The BOS arranges and synchronizes the data from the field equipment, which is processed and translated into the correct format to fit smart building application requirements.
The Building Information Modeling dimensions are the following:
