There are many BIM software vendors, each offering tools with unique advantages and specialized applications. According to incomplete statistics, there are currently over 70 BIM modeling software programs worldwide, with around 25 commonly used. Today, we will explore the question: What software is used for BIM modeling? What are the most popular BIM software options?
1. Autodesk:
Autodesk categorizes its BIM software into three main suites based on their fields of application: the Autodesk Building Design Suite, Autodesk Infrastructure Design Suite, and Autodesk Plant Design Suite. Here’s a breakdown:
1. Autodesk Building Design Suite is primarily focused on construction engineering. It includes several BIM tools such as Revit Architecture, Revit MEP, and Revit Structure:
- Revit Architecture is a 3D architectural design software centered on building models and structural configuration. It uses components like beams, slabs, walls, doors, and windows to create detailed 3D models, helping architects with structural layout and design.
- Revit MEP serves as a platform for mechanical, electrical, and plumbing systems. Its core functions include planning mechanical systems, water supply and drainage, ventilation pipelines, power and lighting circuits, fire protection systems, as well as environmental load and HVAC system analysis. This software supports mechanical and electrical engineers in system analysis and design by building integrated information models.
- Revit Structure specializes in modeling building structural systems such as reinforced concrete and steel frameworks. It assists structural engineers in designing and analyzing structural components.
2. Autodesk Infrastructure Design Suite is tailored for highway, land, and water conservancy projects. Its BIM tools include AutoCAD Civil 3D and Revit Structure:
- AutoCAD Civil 3D is suited for civil engineering tasks. It imports 3D coordinate data to generate terrain models, facilitating pipeline design, land preparation, hydrological analysis, highway alignment, and structural layout on 3D terrain. This aids civil engineers in designing and analyzing infrastructure projects.
- Revit Structure is utilized here as well, with the same functionalities as previously described.
3. Autodesk Plant Design Suite targets factory engineering. It leverages 3D models to improve factory design quality and review processes. This suite also includes Revit Structure, as detailed above.
II. Tekla:
Tekla, a Finnish software company, offers Tekla Structures as its primary BIM software. It is widely used for modeling structural systems such as reinforced concrete, steel, and timber structures, delivering highly precise models.
For reinforced concrete, Tekla Structures allows detailed modeling with components such as beams, columns, slabs, footings, shear walls, brackets, main bars, shear bars, hooks, stirrups, and temperature steel bars. Steel structures can be modeled with various steel types, bolts, and welds. The software also supports structural design, stress analysis, collision detection, and integration with finite element analysis programs, assisting structural engineers in detailed design and analysis during project development.
III. Bentley:
The MicroStation series by Bentley provides application software and technology platforms across diverse fields. Its built-in MVBA programming language is compatible with Microsoft Visual Basic, enabling control over graphic objects and extensive file integration. Bentley software is broadly applied in architecture, highways, railways, bridges, telecommunications, and pipeline engineering. It offers features like animation creation, sunlight analysis, budget reporting, and collision detection.
Key BIM software from Bentley includes Bentley Architecture, Bentley Structural, Bentley Building Mechanical Systems, and Bentley Building Electrical Systems:
- Bentley Architecture enables the creation of 3D building models with seamless switching between 2D and 3D views. It supports architects in structural configuration, analysis, collision detection, and quantity takeoffs, facilitating intuitive communication and reducing complexity.
- Bentley Structural is designed for detailed analysis and design of building structures, supporting reinforced concrete, steel, timber, aluminum, and stone structures.
- Bentley Building Mechanical Systems assists mechanical engineers with the design, analysis, cost estimation, and collision detection of ventilation, piping, and mechanical plant systems using 3D models.
- Bentley Building Electrical Systems supports electrical engineers in constructing, analyzing, estimating costs, and detecting clashes in power, lighting, and fire alarm systems through 3D modeling.
4. Nemetschek AG:
After acquiring Graphisoft in early 2007, Nemetschek AG adopted ArchiCAD—developed by Graphisoft—as its primary BIM software. ArchiCAD is a long-established BIM tool compatible with Apple Macintosh systems. It focuses on architectural design, enabling the creation of 3D building models composed of parameterized objects that include structural dimensions, materials, performance data, and cost information. This supports architects in structural design, analysis, and collaborative workflows.
5. Gehry Technologies:
Gehry Technologies offers Digital Project, a BIM software suite divided into Designer, Manager, and Extensions modules. It excels in managing design and construction operations for complex building projects. Digital Project supports free-form surface modeling to create intricate 3D building models. Through parameterized objects, it assists architects with design, clash detection, visual simulation, construction schedule management, and structural configuration.
That concludes our overview of what software is used for BIM modeling and the most commonly used BIM software available today. We hope this article provides valuable insights for your BIM software selection and understanding!
