BIM (Building Information Modeling) is an information technology application and concept used throughout the design, construction, and operation phases of a project. Employing this approach for control and management can significantly enhance project efficiency, reduce resource waste, shorten timelines, and minimize risks. The concept of BIM was first introduced by Dr. Chuck Eastman from Carnegie Mellon University in his 1975 paper. He described an interactive method where typical elements could generate cross-sections, plans, axonometric, or perspective views from a single description of the relevant components. Any layout change requires only one update operation, ensuring all future drawings remain consistent automatically. Quantitative analysis can be directly integrated into this system, allowing for easy generation of estimates and material quantities. This approach provides a complete and unified database for visual and quantitative analysis, enabling automatic building code verification at city halls or architectural offices. Over time, construction teams involved in large projects have recognized the advantages of this system for schedule planning and material ordering. After continuous development by numerous software companies, the term BIM was officially introduced by Phil Bernstein, Vice President of Autodesk, at the International Union of Architects (UIA). Since 2003, LaiserinJ has actively promoted BIM theory, drawing widespread industry attention and discussion. The hallmark of BIM is its high level of integration of various project-related element information, creating data models through detailed descriptions of geographic information, spatial location, material properties, physical dimensions, and functions. It provides a visual data-sharing platform covering construction progress, processes, cost control, and other related information.
Different organizations offer varied definitions of BIM. The Facilities Information Council within the International Organization for Standardization defines BIM as: “the digital representation of the physical and functional characteristics of facilities and their related project lifecycle information using open industry standards, supporting project decision-making and maximizing project value.” A research group from the University of Pennsylvania’s School of Architecture and Engineering describes BIM technology in their implementation planning report as: “a process designed to improve the design, construction, and operation management of projects or complex facilities by developing, using, and transmitting digital information models of construction projects.” The National Building Information Modeling Standard (NBIMS) defines BIM as: “the computable and manageable representation of the physical and functional characteristics of building facilities and related information throughout their lifecycle, under open industry standards, providing decision-making support and enhancing project value.” In essence, BIM digitally expresses the physical and functional characteristics of facilities, serving as an information resource that offers a platform for sharing data among various users. This platform provides a reliable foundation for all project-related decisions throughout its lifecycle. When applied to a project, different stakeholders can use the model to reasonably edit and extract information at various stages, enabling collaborative work across the entire project management process.
