Recently, I have received numerous inquiries from friends about BIM Technology and its development. Many of them are newcomers to the BIM industry. Therefore, I would like to share my personal insights and a summary of BIM technology’s progress, hoping it will be helpful to everyone.
For a long time, 2D CAD drawings have been widely used in architecture. However, CAD systems lack the ability to independently define and attribute various structures, pipelines, or equipment. This limitation makes it difficult to meet the data demands of today’s complex buildings. As a result, the information technology industry began developing directional concepts to address CAD’s shortcomings. This led to the creation of building information models with 3D views and construction functionalities. When combined with other programming languages, these models enabled the development of systems applicable to a broader range of fields, supporting more complex applications.
According to a survey, the use of 2D computer graphics in architectural design has dropped by 32% over the past decade, while the adoption of BIM for project planning has surged by 85%.
BIM integrates contractors, raw material suppliers, and various planning departments such as measurement, fire protection, and operations. It covers data from multiple fast-moving platforms and organizations. The building lifecycle—including planning, design, construction, operation, and demolition—typically spans a long period. Different participants at each stage often use diverse software, which complicates information integration and communication. When the number of software systems involved grows, the cost and complexity of data conversion rise significantly.
In the late 1970s, some software vendors began creating new building information models. By 1985, the ISO international product module information exchange standard emerged, aiming to unify large-scale data exchange formats in manufacturing. This marked a significant milestone for BIM development.
In the mid-1990s, the International Alliance for Interoperability (IAI) took charge of product standardization and released the first version of the Industry Foundation Classes (IFCs) in 1997. IFCs effectively addressed the challenge of integrating and exchanging information between different software and platforms. Instead of developing software that supported every standard format, IFCs convert all information into a common standard for seamless exchange.
IFCs are an open information format serving as a shared platform. They standardize specific components such as doors, windows, walls, lighting fixtures, furniture, and abstract concepts like space and structure. By managing information in a database format, IFCs enable communication, application, and integration of data from various stages and formats.
BIM is a vast discipline encompassing structural engineering, construction, and operations. It combines overall building strategies, processes, and technological interactions to digitally manage crucial building design and engineering data throughout a building’s entire lifecycle. Among the many BIM-related materials, it is widely recognized that BIM can consolidate fragmented construction information, enhancing building efficiency.
As a result, BIM has rapidly advanced, gaining recognition from numerous organizations and national institutions for its potential impact on construction. Today, BIM is applied in various fields such as civil engineering, joint construction, infrastructure development, and energy analysis. The main reasons for its widespread adoption include:
1. BIM consists of geometric components and parameters tailored to meet the construction needs across diverse fields.
2. BIM offers powerful geometric parameter calculation capabilities and can automatically combine and embed components, making it highly practical for complex modern architectural designs.
That concludes this brief introduction to the development of BIM technology. To ensure accurate building models, BIM requires a complete language and precise geometric planning. This advanced design and engineering system is grounded in the concept of 3D solid geometry and related knowledge, integrating various geometric elements into a comprehensive database.
In architecture, engineering, and construction, 3D building modeling systems include BIM-related software. The field of geometry within BIM encompasses a broad range of expertise, including material properties, manufacturing processes, safety standards, and production conditions. Moreover, it must fulfill the demands of good design and aesthetics.
