In fact, the term BIM was introduced to China in 2006. However, at that time, CAD dominated the industry, and computer hardware was not yet powerful enough to support BIM operations, so its adoption was limited. In recent years, with rapid advancements in computer hardware, BIM technology has experienced a fresh surge in development. Today, I would like to provide an introduction to BIM, hoping it will be helpful to everyone.
Since the concept of BIM was proposed, it has represented a major breakthrough in the construction industry, offering a powerful alternative to the CAD tools that had been in use for decades. Before BIM, the entire lifecycle of engineering projects—including planning, design, construction, and operations management—relied mainly on 2D drawings. These 2D drawings offered limited practical assistance on construction sites or for site management because they lacked linkage and had inherent limitations in management, storage, and interpretation.
In recent years, BIM concepts have evolved to integrate multiple dimensions, or nD models, encompassing various types of project information. For example, 3D models rich in building details combined with project timelines create 4D models for controlling project progress. Adding cost data transforms this into 5D models, which help manage project budgets effectively. This technology is now applied across the entire lifecycle of engineering projects to improve management and control.
BIM has attracted early attention abroad and has been actively applied much earlier than in China. The use of BIM in project management is highly valued internationally. According to surveys, BIM adoption in North America was already well-established by 2013, with over 85% of BIM users having at least five years of project experience.
Particularly in the United States and the United Kingdom, BIM implementation is considered among the most advanced globally. Both countries have not only embraced BIM early on but also developed relevant standards to guide its growth. For example, the UK’s Model Building Homework Standard (AUBS) and the US BIM guidelines, including the National BIM Standard (NBIMS), have played crucial roles in promoting BIM adoption and development in their respective countries.
Since BIM was included in China’s “2011 Development Plan” and the Eleventh Five-Year Plan, the construction industry—from government bodies to enterprises and individuals—has placed great importance on BIM. Many companies have already begun experimenting with and applying BIM, achieving positive results. However, the unique characteristics of China’s construction industry and foreign projects, along with delays in issuing national BIM standards, have influenced the pace of BIM development domestically.
That said, with ongoing local BIM policies and standards being introduced in major cities such as Beijing, Shanghai, and Guangzhou, it is expected that BIM technology will see significant growth over the next three to five years. Let’s look forward to this promising future.
That concludes today’s introduction to BIM. See you next time!
