Modeling of Building Information:

In the architecture, engineering, and construction (AEC) business, building information modelling (BIM) is the cornerstone of digital transformation. Autodesk is the industry’s partner in realising new ways of working and better outcomes for business and the built world as the leader in BIM.

What exactly is BIM?

The complete process of producing and managing information for a constructed object is known as Building Information Modeling (BIM). BIM combines structured, multi-disciplinary data to build a digital representation of an asset across its lifespan, from planning and design to construction and operations, using an intelligent model and a cloud platform.

Why is BIM adoption so high?

Explore the new Dodge Data & Analytics research, which describes the sector as being on the verge of a tipping point, with most BIM-using businesses now adopting BIM on more than half of their projects–a trend that’s driving digital transformation across the industry and around the world.

Acceleration of BIM by industry:

Even late-adopter sectors will be utilising BIM on the bulk of their projects by 2024, according to a recent Dodge Data & Analytics analysis.

Civil engineers: 46 percent of BIM-using civil engineers say BIM is used on more than half of their projects, with a total of 72 percent predicted by 2024.

Contractors use BIM on more than half of their projects, according to 41% of BIM users.

From blueprints CAD to BIM:

From blueprints to computer-aided design (CAD) to building information modelling (BIM),

Previously, blueprints and drawings were utilised to convey information about a specific construction plan. This 2D method made visualising dimensions and needs extremely challenging. 

Then came CAD (Computer Aided Design), which enabled drafters to understand the value of blueprints in a digital setting. Later, CAD became 3D, allowing plans to have more realistic images. BIM (Building Information Modeling) has become the industry standard, but it is far more than a 3D model.

The “I” in BIM stands for “Building Information Modeling.”

BIM refers to the process of collaboration and data exchange among all stakeholders engaged in the development and lifetime management of built assets. The ultimate power of BIM, however, is found in the “I.” (information). All of the data obtained, from conception to completion, is not only saved, but also used.

Paper-based drawings + no collaboration = Level 0 BIM.

The term “level 0 BIM” refers to not working together at all. You may confidently claim you’re at level 0 if you’re utilising 2D CAD and dealing with drawings and/or digital prints. Although not every expert in the industry has appropriate BIM training, and some projects do not incorporate the usage of BIM in contract requirements, the majority of the industry is already functioning beyond this level.

Level 1 BIM consists of 2D construction drawings as well as 3D modelling.

You’re definitely using Level 1 BIM if you use 3D CAD for idea work but 2D for drafting production information and other paperwork. At this level, CAD standards are handled according to BS 1192:2007, and data is shared electronically through a common data environment (CDE), which is normally controlled by the contractor. Many businesses use Level 1 BIM, which requires less cooperation and allows each stakeholder to publish and maintain their own data.


BIM Level 2: Teams create their own 3D models.

In Level 2 BIM, a collaborative environment is introduced. In April of 2016, BIM Level 2 became a legal requirement for all publicly funded projects in the United Kingdom. In 2017, France was the next country to get their own mandate.

At level 2, everyone on the team uses 3D CAD models, although not always in the same model. However, it is distinguished from other levels by the manner in which stakeholders communicate information. A standard file format is used to transmit information on the design of a built environment.

Level 3 BIM: Teams collaborate on a 3D model that is shared:

Level 3 BIM allows for even more collaboration. Level 3 indicates that instead of each team member working on their own 3D model, everyone utilises a single, shared project model. The model lives in a ‘centralised’ environment that anybody may access and modify. This is known as Open BIM, and it adds another layer of protection against conflicts while also adding value to the project at each level.


The following are some of the advantages of Level 3 BIM:


  • A more accurate 3D representation of the full project
  • Multiple teams and deals can easily collaborate.
  • Streamlined communication and comprehension of design intent
  • At every level of the project, there was less rework and modifications.


BIM Levels 4, 5, and 6: Including schedule, cost, and sustainability data

Level 4 of BIM introduces a new component to the information model: time. This data comprises schedule data that shows how long each phase of the project will take and how the various components will be sequenced.

Cost projections, budget analysis, and budget tracking are all included in Level 5 BIM. When working at this level of BIM, project owners can keep track of and predict how much money will be spent throughout the course of the project.


  • Level 6 BIM data is important for estimating a building’s energy usage before it is built. This ensures that designers consider more than just the asset’s initial expenses. Level 6 BIM ensures realistic energy consumption projections and helps stakeholders to construct energy-efficient and sustainable structures.


BIM in the Future:


BIM is here to stay due of its obvious advantages.

It contains clearly defined aims and objectives that benefit everyone who progresses through the stages. Construction will undoubtedly become increasingly more collaborative and digital in the future. 4D, 5D, and even 6D BIM will begin to play a role in the process as BIM grows more advanced.
