The Nordic system adopts the IFC data standard format, which is highly developed, detailed, and practical. In contrast, the Anglo-American system encompasses a broad and comprehensive range of standards, forming a well-coordinated framework that aligns national and local regulations.
The Asian system primarily focuses on project-level applications, with less emphasis on data standards. The “BIM Design Standards” are based on data standards but prioritize BIM application, aiming to standardize the delivery and management of project lifecycle information. This positions the system as application-oriented within the Asian context.
In July 2015, the Ministry of Housing and Urban-Rural Development issued the Guiding Opinions on Promoting the Application of Building Information Modeling (BIM), explicitly requiring the formulation of relevant engineering construction standards and application guidelines to establish a BIM application standard system. This system is structured into three tiers: national standards, industry and local standards, and enterprise and project standards. The “Enterprise BIM Model Standard” falls under the enterprise-level category.
The development of the “Enterprise BIM Model Standard” is tailored to meet specific enterprise needs such as cost control, quality monitoring, planning, and operation and maintenance management. These requirements translate into concrete BIM model standards, giving the standard a customized nature. It covers modeling standards, delivery standards, design applications, interface applications, and regulations concerning model resources.
Guided by management demands like design documentation, cost management, quality assurance, and scheduling, the standard centers on BIM data transmission. Through these standards, crucial information for successful project execution can be extracted from BIM models, clarifying the required data attributes. Standardizing relevant practices and verifying outcomes help promote the establishment and enforcement of enterprise BIM control systems.
The standard should exhibit the following characteristics:
1) Alignment with international BIM development trends: European and American BIM standards have evolved early, establishing a comprehensive and advanced basic data standard system. Building upon these, Asian efforts focus on developing application standards and promoting their implementation.
2) Compliance with national BIM development strategies: The country has devised a multi-level BIM standard development approach, covering national, local, and enterprise standards.
3) Adaptation to enterprise BIM application needs: The standards are designed to directly address the specific features of enterprise projects, including design, cost, planning, and quality supervision.
