In recent years, with the rapid advancement of computer technology, the scope of Building Information Modeling (BIM) technology has expanded significantly. BIM is not a software or a collection of software tools; rather, it serves as an auxiliary tool in the process of building informatization.
BIM works by creating a virtual model that acts as an information carrier. A vast amount of engineering data is linked and integrated into this model, resulting in a representation that contains actual engineering information. The BIM process encompasses model creation, project management, process control, and maintenance operations, enabling digitization and visualization throughout the entire lifecycle of a construction project.
Essentially, BIM provides a collaborative platform where multiple stakeholders can participate simultaneously, sharing information about project progress, costs, quality, and performing analyses of buildings or facilities.
Currently, the mainstream BIM modeling software available in the market falls into three main categories:
(1) Revit by Autodesk: Revit is a professional BIM software developed by Autodesk. Leveraging AutoCAD’s strong presence in the civil construction industry, Revit holds a significant market share both domestically and internationally.
(2) Bentley Series by Bentley Systems: Bentley offers a suite of BIM software based on MicroStation. These products are particularly strong in factory design—covering industries such as petroleum, chemical, power, and pharmaceuticals—as well as infrastructure projects like roads, bridges, municipal works, and water conservancy.
(3) CATIA by Dassault Systèmes: CATIA is among the world’s most advanced mechanical design and manufacturing software. It provides 3D design and simulation solutions across eight major sectors, including automotive, aerospace, shipbuilding, factory design, architecture, power and electronics, consumer goods, and general machinery manufacturing.
In the engineering and construction industry, BIM offers significant advantages in modeling, visualization, and information management, particularly for complex and large-scale projects.
