Traditional schedule management tools have improved project scheduling efficiency to some extent, but they still have significant limitations. Firstly, CAD technology presents several challenges. The volume of work required to complete the construction phase using CAD can range from dozens to thousands, or even tens of thousands, of drawings. The limited capacity of workers makes errors inevitable. Moreover, independent design efforts across different disciplines often lead to spatial conflicts between drawings. Despite extensive review processes, numerous clashes and mistakes still occur. Additionally, 2D CAD drawings are complex and difficult to interpret, which can cause misunderstandings and communication barriers. For buildings with unique shapes or complex structures, CAD alone struggles to provide clear design and expression.
Secondly, network planning also has its drawbacks. Network diagrams tend to be computationally complex and hard to understand, which hampers effective communication and interaction. Their abstract nature prevents a visual representation of project progress, making it difficult to track actual developments.
Network planning’s accuracy is limited by the lack of detailed project work breakdowns and its reliance on experience to define logical relationships, which can lead to unreasonable schedules. Changes during construction, such as engineering adjustments or environmental factors, require timely plan updates. However, network plans are often rigid, and making adjustments or optimizations can be complicated. Thirdly, traditional project management software like Microsoft Project and Primavera P6 has limitations. These tools offer two-dimensional, flat representations of schedules, making it difficult to display real-time spatial and four-dimensional information during construction. This restricts effective schedule planning and control.
Fourthly, traditional schedule management heavily depends on the experience of project managers. This reliance makes it challenging to establish standardized, regulated management models, which in turn reduces management efficiency. Furthermore, traditional methods do not provide integrated information models, making it difficult to achieve rapid collaborative design, engineering visualization, or environmental impact analysis—capabilities that are essential for modern construction projects.
Building Information Modeling (BIM) technology addresses these issues by enabling full sharing and lossless transmission of construction project information throughout all phases: planning, design, construction, and operation. BIM allows all stakeholders to interact with both the information and the model throughout the project’s lifecycle, promoting collaborative work. This fundamentally transforms previous project management approaches that relied on blueprint-based, text-symbol representations.
BIM is grounded in the concept of lifecycle management and supports every stage of a project—from conception and construction to operation, renovation, and demolition—playing distinct roles in each phase. Its impact on the construction industry is profound. In some developed countries, early research and adoption of BIM have placed them ahead of China in this technology’s application, demonstrating its potential.
Internationally, BIM has been applied across the design, construction, and maintenance stages of projects. Within China, an increasing number of projects have integrated BIM to varying degrees at different stages. For instance, the Shanghai Center Building project implemented comprehensive BIM planning throughout design, construction, and operation, setting a benchmark for owner-led BIM applications across the project lifecycle. Although BIM development in China is still in its early stages and not yet fully mature—especially in the construction phase, which requires deeper research and hands-on practice—ongoing advancements promise wider adoption and significant benefits for the construction industry.
