The BIM software market is currently experiencing rapid growth, with numerous developers emerging both internationally and domestically. Leading foreign companies include Autodesk, Bentley, Nemetschek, Graphisoft, and GeryTechnology Dassault. The most popular software among these are Autodesk Revit, primarily used for civil architecture; Bentley, favored for factory design and infrastructure projects; ArchiCAD, preferred by specialized architectural firms; as well as DigitalProject and CATIA, which are suited for complex and well-funded projects. In China, the main software providers include Luban, Guanglian Da, and Sver.
Regardless of the manufacturer, BIM software generally falls into two categories: modeling software and application software. Modeling software focuses on creating 3D models, enabling visualization and simulation while incorporating information input and calculations throughout the process. On the other hand, application software—also known as the BIM application side—is used for building and modifying existing models. This approach ensures smoother workflows and higher efficiency compared to the modeling side alone.
To illustrate, let’s consider Autodesk Revit, the most widely adopted foreign BIM software. Revit’s modeling side is divided into disciplines such as architecture, structure, and mechanical, electrical, and plumbing (MEP) systems. Models are created separately for each discipline and then linked together. Navisworks is often used in conjunction with these models for clash detection, schedule simulation, and construction animation.
During practical use, two major challenges arise, which are also common issues among foreign BIM software. First, creating steel reinforcement models is extremely slow and inefficient, requiring high-end hardware. In practice, modeling steel reinforcement for an entire project is nearly impossible, making accurate quantity takeoff unfeasible. Second, the software lacks intelligent data extraction capabilities to meet current construction needs. For example, when preparing material plans for construction flow sections divided by zones and floors, Revit does not support sectioning or quantity takeoff by floor.
Furthermore, foreign BIM software often fails to meet localized requirements. They typically lack integrated quota and checklist modules and cannot calculate components beyond physical volumes, such as formwork.
