BIM technology is a data-based tool that can be applied to the design, construction and management of engineering structures. Through the integration of data-based and information-based system models of buildings,Bentley ProjectWise financial sharing and transfer is required during the whole life cycle of project planning, operation and maintenance, so that engineering and construction technology researchers can make a correct understanding and high efficiency response to various different construction enterprise information society.

The core of BIM is to establish a virtual three-dimensional model of the construction project, and use digital technology to provide a complete and consistent information base for the model.Bentley BIM This information base contains not only the geometric information, professional attributes and state information of building components, but also the state information of spatial and motion behavior of non-component objects. With the help of this 3D model,BIM Viewer the integration of construction information is greatly improved, and a platform is provided for various stakeholders to communicate and share construction information.

Next, let's see what preparatory work should be done before building a compliant BIM model.

I. Define the project type

1. Define the type of project to be implemented.

Understand the nature and type of the project based on the relevant information provided.

The nature of construction projects is divided into: a new project, remodeling projects, expansion and development projects, relocation projects, restoration of business projects.

Using different nature is divided into: residential construction project, commercial bank project, office building project, hotel management project, hospital project, data information center project, industrial enterprise project, decoration project, etc.

According to the application stage of BIM, it is divided into planning stage, design stage, construction stage and operation and maintenance stage.

2.Contract text:Contract disclosure according to the specific content of the contract text.

II. Clarify specifications and requirements

1. Clarify the scope of modeling implementation

If there is a contract, the scope of application should be determined in accordance with the relevant provisions of the contract.

There is no contract in accordance with the relevant requirements, such as building, area, system, etc.

2. Define the modeling implementation standards

Determine the type of software used, software version, modeling accuracy, and project application points.

3. Define project delivery standards

Determine the format of the delivery document, the relevant technical standards of the delivery document and some other specific rules of the enterprise.

Determine the project time node

According to the time nodes required by the project, formulate the corresponding work division and BIM work schedule.

5. Define whether the conditions for project implementation are available.

Verify whether the drawings have been provided, whether the drawings are complete, whether the quality of drawings meets the modeling requirements, and whether the time nodes can be met.

Implement whether the existing conditions are met, such as hardware and software facilities, staffing, etc.
