Currently, the term BIM is commonly understood as the abbreviation for “Building Information Modeling.” In Chinese, it is translated as “Building Information Modeling” as well. The concept was first introduced in 1974 by Dr. Chuck Eastman, who highlighted the comprehensive processing of graphics through information technology while considering the properties of buildings. This approach allows for a more scientific classification of various building attributes based on their functionality. The industry widely recognizes this as the foundational idea behind BIM.
Since the turn of the century, as attention and research on BIM have increased, the British Standards Institution (BSI) has further refined and interpreted its definition with specific clarifications:
(1) Building Information Model – emphasizes a static information model.
(2) Building Information Modeling – emphasizes the process of creating the model.
(3) Building Information Management – focuses on using information models for project management.
In 2007, the United States National BIM Standards Project Committee released the first version of the National BIM Standard (NBIMS), providing a comprehensive definition of BIM:
(1) BIM is a digital representation of the physical and functional characteristics of a facility.
(2) BIM serves as a shared knowledge resource and a process for sharing information about a facility. It provides a reliable basis for all decisions throughout the facility’s entire lifecycle, from initial concept to demolition.
(3) At different project stages, various stakeholders insert, extract, update, and modify information within the BIM. This supports and reflects their respective responsibilities in collaborative work.
In June 2015, China’s Ministry of Housing and Urban-Rural Development issued the “Guiding Opinions on Promoting the Application of Building Information Modeling,” further elaborating on the concept:
BIM is defined as a multidimensional model information integration technology developed on the basis of computer-aided design (CAD) and other technologies. It acts as a digital carrier and visual representation of the physical and functional characteristics of building projects. BIM can be applied across all project phases, including planning, surveying, design, construction, operation, and maintenance.
This approach enables data sharing among all participants throughout the building’s entire lifecycle, based on a unified multidimensional building information model. It provides technical support for integrating the industrial chain, promoting industrialized construction, and fostering the creation of high-quality buildings.
