BIM can be simply described as “creating a virtual building on a computer beforehand, simulating different scenarios, addressing potential problems in advance, or taking preventive measures, and then implementing the plan.” This concept has existed for a long time. Before the term “BIM” was coined, the broader idea of “Virtual Design and Construction” (VDC), introduced by the Center for Integrated Facility Engineering (CIFE) at Stanford University, was widely used. It wasn’t until 2002, when Autodesk acquired the Revit software series, that the concept of “BIM” was formally proposed and successfully popularized. Today, BIM is widely recognized and adopted.
The American Academy of Building Research views BIM as a new concept and practice that drives major changes through innovative information technology and business models. BIM is expected to revolutionize the construction industry by significantly reducing various forms of waste and inefficiency. Construction projects involve extensive collaboration, often requiring multiple organizations to work closely within a single environment. By integrating building project networks, BIM technology dramatically enhances productivity. It delivers unparalleled advantages to the construction sector and society at large by enabling better building practices—reducing costs, minimizing engineering errors, and lowering operational expenses.
Currently, the most widely accepted definition of BIM in China is Building Information Modeling. It refers to a “visualized” digital building model created using advanced 3D digital design and engineering software. This technology provides a collaborative platform for designers, architects, plumbing engineers, developers, and even end-users to simulate and analyze projects. Using 3D digital models, stakeholders can manage the design, construction, and operation phases more effectively. The ultimate goal is to optimize resource planning, manage financial risks, save energy and costs, reduce pollution, and improve efficiency throughout all stages of a project’s lifecycle. BIM enables comprehensive lifecycle management of engineering projects.
The adoption of BIM technology supplies essential data for engineering projects, ensuring that leadership decisions are made quickly and accurately. As a result, BIM has been extensively applied across various fields and stages of construction, as well as in post-project operation and maintenance.
