The BIM platform contains comprehensive information to support various design operations, including object creation, editing, and modification. It carries parameters and essential rules to ensure the architectural model’s spatial accuracy. These platforms often integrate numerous embedded tools for modeling, perspective views, rendering, and more.
Different user groups and project phases utilize BIM platforms for distinct purposes. For instance, architects rely on them for design modeling and drafting during the architectural design phase. Structural engineers manage data through these platforms, while contractors use them for coordinated model building and facility management during construction. BIM platforms offer diverse functionalities tailored to multiple user types.
Currently, there are four leading BIM platforms in China:
(1) Revit: Revit currently leads the architectural design market in BIM and is one of the most widely adopted software platforms within China’s construction industry BIM ecosystem. Autodesk launched Revit in 2002 after acquiring a startup’s original program. The Revit product family includes Revit Architecture, Revit Structure, and Revit MEP, catering to architecture, structural engineering, and mechanical/electrical disciplines respectively. Known for its power, intuitive interface, ease of learning, and extensive object library, Revit is a robust design tool. However, it demands significant memory resources, and performance slows down with large file sizes. Additionally, it has limitations when designing complex surface geometries.
(2) Bentley: Bentley offers a broad range of products for architecture, mechatronics, public construction, and infrastructure projects and holds a strong presence in civil engineering markets. It provides most of the building modeling tools needed to cover nearly all aspects of the AEC (Architecture, Engineering, and Construction) industry. However, Bentley’s products are only partially integrated in terms of data consistency and user interface, which means users may face a steeper learning curve and require more time to operate the software effectively.
(3) ArchiCAD: ArchiCAD is the oldest BIM application provider focused on architectural design. Its parent company, Graphisoft, began selling architectural CAD software in the early 1980s. ArchiCAD features a user-friendly and intuitive interface, with advanced collaborative project capabilities that surpass many other systems. It supports efficient teamwork and object-level design coordination. That said, ArchiCAD’s parametric modeling customization options are somewhat limited.
(4) CATIA: CATIA is a globally leading parametric modeling platform primarily used in large-scale aerospace and automotive systems. It offers powerful and comprehensive parametric modeling functions that enable precise control over surfaces, features, and assemblies of complex integrated components. In China, many challenging BIM projects, such as external curtain wall designs, utilize CATIA. Its drawbacks include a steep learning curve due to a complex interface and high initial costs. Additionally, its drawing publishing capabilities for building applications remain underdeveloped.
