What is BIM, what is BLM and what is Dassault BIM?

BIM is the acronym of BuildingInformationModeling, which is a technology. I translated it into building model informatization, and some teachers translated it into modeling informatization model, depending on personal understanding. These two words are not in the same order, so there are some differences in understanding. The key point I understand is the informationization behind them.

First, the development background of BIM concept

The first oil crisis broke out in the world from 65438 to 0973. Due to the shortage of oil resources and rising prices, the whole industry in the United States is considering energy saving and efficiency improvement.

In 1975, Professor ChuckEastman of Georgia Institute of Technology, the "father of BIM", put forward the "BuildingDescriptionSystem" to realize the visualization and quantitative analysis of building engineering and improve the efficiency of engineering construction.

In 1999, Eastman developed "building description system" as "building product model", and thought that building product model can provide rich and integrated information in the whole life cycle of building products from concept, design, construction to demolition.

In 2002, Autodesk acquired RevitTechnology, a three-dimensional modeling software company, and connected the initials of BIM(Building Formation Modeling) for the first time, which is known as "BIM" today.

Second, the concept of BIM

B: Building is not a house in a narrow sense, but a part of a building, a house or a building project.

I: information, "information", is divided into geometric information and non-geometric information. Geometric information is measurable information in buildings, and non-geometric information includes time, space, physics, cost and other related information.

M: From the design stage, it is divided into three levels and three progressive concepts:

Model and digital expression of physical and functional characteristics of building facilities

Modeling is based on the model, which is dynamically applied in the design, construction, operation and cost stages to help improve work efficiency and reduce costs.

Management is the collaborative management of multi-dimensional and multi-participant information on the basis of modeling.

Third, the advantages of BIM

Visualization: BIM is more vivid and intuitive than CAD drawings.

Coordination: in the early stage of building construction, coordinate the collision problems of various professions and generate coordination data.

Simulation: In the design stage, BIM can carry out some simulation experiments.

Optimality: Choose the best scheme by comparing different design schemes.

Printability: release professional drawings and deepen drawings to make the engineering expression more detailed.

The above is a brief interpretation of BIM, from development to concept to characteristics. Looking at this technology rationally, it includes not only a series of software foundations, but also a model, an animation and a construction process.

BIM is the general name of a technology, which takes a specific workflow as the carrier, uses various information software to informatization construction projects, and promotes the development of social informatization.

Dassault BIM is the BIM of dassault systemes Company.

By adopting new technologies and flexible and adaptable platforms, construction engineering companies can customize, deploy and package the workflow that best suits their needs. The company can expand its professional knowledge in the whole project delivery process and expand its creation more widely in construction projects. The new platform provides a wide range of tools for all aspects of development and project delivery, far exceeding the digitalization of traditional building information.

Related functions of BIM dassault systemes

(1) extend workflow

Online dashboards enable enterprises not only to manage information,

But also to understand and control how information is generated, collected and distributed.

② Expand the scope.

With a more powerful platform, the company can

Further expand the scope of project creation,

By expanding information beyond traditional silos,

Create opportunities to cover a wider range.

③ Expand the process.

Seamless interconnection of design information with manufacturing and construction processes,

Promote the expansion of technology and professional knowledge.

(4) Expand knowledge.

The acquisition of knowledge provides flexibility to change at any time.

Accelerate project delivery time and promote future reuse.

5] Expand integration.

Information can be integrated from different sources,

Enables companies to adopt a wide range of tools,

And eliminates the need for all team members to adopt a single platform.

(6) Expand exchanges.

The cloud platform allows remote hosting of all model and project information.

It is convenient for all kinds of users to exchange information seamlessly from different places.

In short, as a relatively easy-to-use BIM platform, although Dassault's Chinese name may not be widely known, it is enough for you to know CATIA. Therefore, while using CATIA's BIM software, you can start to apply BIM dassault systemes.
