What is the Development History and Theoretical Significance of BIM?
The development of Building Information Modeling (BIM) began in the 1970s. Eastman et al. (2011) from the Georgia Institute of Technology proposed that computer systems could eventually be used to simulate building structures. They called this system the “Building Description System.”
In 1986, American scholars Aish & Noakes (1984) introduced the concept of “Building Modeling.” From the 1970s to the early 1990s, due to limited 16-bit CPU memory and low graphics processing capabilities, major global graphics workstation manufacturers such as DEC, SGI, SUN, HP, and IBM focused on developing computer-aided building graphics, design, and simulation systems at the hardware level. However, because of the high cost of hardware and the limited functionality of software, the global construction industry mainly used computer simulation for laboratory research rather than practical applications.
In 1989, I served as an agent for BIG D computer graphic rendering software. At that time, I used Autodesk R10 to create 2D drawings and then applied 3D BIG-D software for sunlight simulation rendering. The hardware used was an HP Vectra 386 PC. On average, it took between 8 to 24 hours of computation to generate 3D models through simulation. This low efficiency was a significant barrier to commercialization at the time.
Entering the 21st century, rapid advancements in software and hardware occurred. Professional graphics chips, such as GPU 64-bit engines and multi-core processors, enabled parallel computing operations. For example, Nvidia made breakthroughs in 3D simulation efficiency (Dalton & Parfit, 2013). In 2002, Autodesk introduced the term Building Information Modeling (BIM), marking a major innovation in computer-aided design. Today, BIM is a vital productivity tool that addresses practical challenges in the construction industry.
Definition of BIM
BIM has multiple definitions, but the US National BIM Standard (Annex & Rules, 2015) provides a comprehensive explanation on four levels:
- The digital representation of the physical and functional characteristics of a facility (building project).
- A shared knowledge resource.
- Information shared about the facility that supports reliable and evidence-based decision-making throughout the entire lifecycle, starting from conceptual design.
- At various project stages and among different professional parties, information is continuously added, captured, updated, and modified within the BIM model to support collaborative work and fulfill respective responsibilities.
Mainstream BIM Software Worldwide
Leading companies like Autodesk, Bentley, Tekla, and ArchiCAD have developed BIM system tools alongside advances in information technology. For example, Autodesk’s Revit SDK (System Development Kit) enables the creation of Revit plug-ins. These applications handle not only geometric parameters (X-Y-Z) but also 3D model components with attributes such as equipment, material codes, construction procedures, materials, personnel time, and costs. They establish a BIM component database that can be extended and integrated to develop augmented reality (AR), virtual reality (VR), intelligent building systems, 4D schedule management, 5D cost control, BIM-ERP, facility management, asset management, and operations management systems.
Moreover, the integration of Internet of Things (IoT), cloud computing, and big data technologies brings innovative value to BIM-based projects.
That concludes our discussion on the development history and theoretical significance of BIM. I hope this article provides a clearer and more comprehensive understanding of BIM’s evolution and its impact on the construction industry.
