What are the standards for BIM modeling and application?

The creation of a bim model is one of the most important aspects of completing a BIM project, and the standard of model creation can be considered key to the success of the project.Bentley ProjectWise What are the standards for BIM modeling and application today?

BIM building modeling standards

Prefabricated components and assembled building components can be placed as objects in a BIM model.

Building components should be constructed using the correct tool,Bentley BIM when the available tool is insufficient

The tool builds the object, but the object "type" should be defined correctly.

Components that are smaller than the modeling needs do not need to be modeled,BIM Viewer as shown in the 2D drawing.

The BIM model can be supplemented with 2D detail drawings.

Building components should be organized separately according to floors.

Requirement parameters - type, material, ID and size, where the "type" parameter is used as a basis for quantity selection.

If more than two tools can be used to model a component, the completed component should be clearly defined by "type". For example, if two tools can be used to model a roadway, a plate and a beam, the "Type" parameter of the completed roadway should be set to "Roadway".

Structural components should be organized according to the dimensions provided by the structural engineer.

BIM Structural Modeling Standards

The contractor and subcontractors work together to adapt the detailed model to the construction model based on the construction assembly method and deepen the structural model with fabrication drawings if necessary.

The structural consultant will produce a structural analysis model and a structural BIM model based on actual component locations and dimensions, which will generate structural documentation.

Prefabricated and prefabricated structural components can also be designed with other special tools, built and then incorporated into the structural BIM model.

The structural BIM model includes all load-bearing concrete, wood, and steel frames, as well as non-load-bearing concrete frames. The basic components include walls, slabs, beams, and lattice frames, which need to be built with the right tools (e.g., walls, slabs, etc.). . If the correct tool is not available, the components can be constructed with other suitable tools, but the "type" of component should be correctly defined.

Structural modeling can be divided into different phases depending on the requirements of the structural submittal.

During detailed design, reinforcement and nodes can be modeled in detail using appropriate modeling tools.

Components smaller than the modeling requirements do not need to be modeled, but can be supplemented with 2D drawings. Example: Components smaller than 10 cm do not need to be modeled.

2D drawings can be used for load planning.

If BIM modeling software is limited, 2D drawings can be used to create column details, which should include column shapes and sections.

Structural components should be organized in layers according to floors.

Parameters to carry out the requirements: type, material, ID code, and size different dimensions, where the "type" parameter is used for quantity feature extraction methods.

When two or more tools are available for creating assemblies, the generated assemblies need to be explicitly defined by type.

Mechatronics (MEP) Modeling Criteria

Model parts that require special attention.

Explicitly mark parts that have been changed by the construction manufacturer and approved by the engineering consultant.

Objects that can be absent from the BIM modeling and analysis tool can be replaced with box shapes, but need to be labeled with a name and given the appropriate parameters for the student to carry out.

The elevation of each system component (based on finished floors or other data) should be clearly labeled.

You may model fasteners and hooks if necessary.
