Background of BIM Technology
Firstly, the complexity of our projects is continuously increasing. This includes larger project sizes as well as the integration of diverse and heterogeneous components. Currently, we rely on 2D drawings, which, as we know, are insufficient for addressing these complex challenges.
Moreover, users today demand higher product quality, emphasizing energy efficiency, green building practices, and sustainability. These requirements mean that designing a building is not just about construction; it also involves ensuring the overall quality, energy efficiency, and environmental friendliness of the final product. Additionally, the design must meet the functional usability needs of the occupants throughout the process.
Secondly, from another perspective, although computer-aided tools have replaced traditional drawing boards, they still function essentially as digital drafting platforms. This approach lacks sustainable technological solutions necessary for truly sustainable design. Currently, building analysis is still performed using 2D drawings and fragmented components, which limits efficiency and integration.
Thirdly, market demands are evolving alongside increasing project complexity and higher quality expectations. Due to intense competition, owners are becoming more stringent about controlling project timelines and costs. This has led to the emergence of a phenomenon known as “scattered vacancies” within the industry. These scattered gaps often require changes, and any modifications, errors, or omissions pose significant risks to both schedules and budgets.
Fourthly, global competition is intensifying. For example, many iconic buildings in China, such as the National Centre for the Performing Arts and the Bird’s Nest, were designed by foreign architects. However, domestic design institutes typically provide much of the backend design support for these projects. This work is often referred to as “mental labor in design,” reflecting the fact that while domestic teams complete approximately 80% of the work, they receive only about 20% of the revenue.
