BIM is the result of informatization, standardization, and normalization within the construction industry, serving as a powerful tool for efficient modeling and information integration. However, challenges remain in standardized management, software application, and practical operations. These issues primarily manifest as repetitive and inefficient software modeling tasks, insufficient guidance and promotion of standards, and a disconnect in collaborative management efforts. The main obstacles hindering the localization and development of BIM in China can be summarized as follows:
Lack of Unified Standards
Since the 1950s, the manufacturing industry in the United States has embraced CAD technology, leading to a successful transformation through information technology. Many traditional industries in the US began integrating modern IT solutions to boost production efficiency. Today, BIM stands as a mainstream technology in the construction sector, attracting widespread industry attention.
As more construction projects adopt BIM technology, various BIM standards have emerged both domestically and internationally. These variations stem from differing participant interests, application goals, software platforms, and familiarity with BIM concepts.
BIM holds significant market potential in the soil and wood industries. By standardizing and regulating these sectors, building a mature framework and platform, promoting development, and fostering a sustainable information ecosystem, BIM can thrive. On September 19, 2016, China’s Ministry of Housing and Urban-Rural Development issued the “Outline for the Development of Information Technology in the Construction Industry from 2016 to 2020,” emphasizing the accelerated improvement of BIM application standards.
Although early standards lacked foresight and comprehensive planning, ongoing industrial informatization and strong government support are expected to gradually enhance these standards.
Lack of Interactive Technology
BIM applies throughout the entire project lifecycle, involving numerous professional disciplines. By leveraging digital technology to create 3D models as virtual carriers of project information, BIM software strives to present a comprehensive information model of the entire project. This is essential for enabling both vertical and horizontal information flow.
However, in China, where BIM technology adoption is incomplete and software development remains constrained by market demands and industry needs, misconceptions about BIM persist. BIM is not just software; it represents a complete application system requiring seamless information exchange among various software tools.
The core BIM modeling software forms the foundation for secondary development, allowing customization through multi-level information exchange. Currently, China lacks robust core BIM modeling software. Yet, BIM’s true focus lies not in modeling alone, but in the practical application of those models.
Critical challenges include how to seamlessly connect software across different domains and enable interoperability between diverse file formats. Addressing these issues is vital for effective information processing, transmission, and storage.
To realize the full potential of BIM, it is essential to develop a healthy industry chain, build integrated software systems, and combine software with complementary functions to maximize BIM’s value in construction projects.
Balancing relationships between BIM software developers and users through government regulation, alongside market demand and industry coordination, will help establish a BIM software ecosystem tailored to China’s construction projects. Key steps include understanding information flow between software, accelerating the development of compatible interfaces, and expanding domestic BIM software with government support.
Lack of Collaborative Management
At its core, BIM technology promotes computer-based collaboration, aiming to integrate the entire construction project. This involves achieving information exchange and sharing through the storage, processing, and integration of a single data source, catering to the information needs of all stakeholders and project phases.
However, due to fragmented project workflows and varying terminology and standards across professions, communication breakdowns and misunderstandings often occur during project handovers. This leads to delays, increased costs, and fragmentation of the holistic BIM concept.
To fully realize BIM’s benefits, it is crucial to establish a management model that integrates information throughout the project lifecycle. Building an information collaboration system that involves all parties and reaching consensus on overall project management are essential.
Through effective information collaboration, project processes can be better coordinated, aligning closely with business operations and organically integrating project management efforts.
