The current status and challenges of BIM (Building Information Modeling) applications in China can be analyzed from six key perspectives: construction companies, design institutes, owners, consulting firms, government, and educational institutions.
1. Construction Companies
(1) Current Situation
BIM adoption in construction enterprises mainly occurs at two stages. First, during the bidding process, many projects require BIM technology proposals. Construction firms develop BIM solutions focusing on model creation, clash detection, decoration planning, cost estimation, scheduling, and virtual walkthroughs, primarily using Revit and Navisworks software. Second, before installing mechanical and electrical pipelines, BIM’s core value for construction companies lies in clash detection and cost calculation, supplemented by virtual walkthroughs and decoration planning. Clash detection helps identify spatial conflicts in drawings, reducing delays and rework. Cost estimation supports budget control, while virtual assembly and decoration plans assist in client presentation, award applications, or contract value increases.
Regarding staffing, construction companies typically do not differentiate BIM personnel by discipline (architecture, structure, MEP); instead, BIM team members collaborate across these areas.
Notably, BIM adoption in building industrialization by construction firms has improved significantly in the past six months. For example, while many companies resisted BIM until March this year, viewing experience as superior, recent developments show increased willingness to learn BIM, reflecting broader industry changes.
(2) Limitations
There are six main challenges hindering BIM application in construction companies:
Software Limitations: Construction firms primarily rely on Revit and Navisworks, with limited use of plugins or API development. This restricts capabilities beyond clash detection and cost estimation, such as safety simulation, material usage feedback, and site layout optimization.
Model Detail Level: For example, a foundation project in Taiwan featured models detailing every steel bar arrangement, a level rarely achieved in mainland China. Without such detail, design issues often go undetected, risking construction complications, such as inadequate reinforcement spacing.
BIM Staffing Shortage: There is both a lack of modelers and insufficient BIM technical depth. Even leading firms have a low BIM personnel ratio, leading to overworked modelers or insufficient integration between models and on-site realities. Training often focuses on software operation, with many young, inexperienced trainees, limiting model refinement and development.
Lack of Simulation Methods: Construction firms struggle to simulate construction processes before execution. Complex operations often rely on expert demonstrations and animations rather than dynamic model-based simulations. For example, simulating how two cranes operate simultaneously without interference is difficult, despite BIM’s potential to address such issues.
Visualization Technology and Equipment Deficit: Technologies like AR and holography can significantly improve communication and efficiency on site, especially for complex drawings. However, these tools are rarely deployed, limiting their potential to enhance construction understanding and coordination.
Improper Cost Estimation Application: While construction firms are increasingly adopting BIM-based cost estimation, market pressures lead to improper use. For instance, winning bids at low prices followed by revenue increases through change orders remain common. Variations in cost estimation software algorithms can cause discrepancies exploited to adjust costs unfairly. This misuse hampers BIM development within construction companies.
2. Design Institutes
(1) Current Situation
Many design institutes have formed BIM teams, but BIM usage remains more theoretical than practical. Most equate BIM with Revit and focus on modeling, rendering, lighting and energy analysis, and 2D drawing optimization. BIM is often treated as a supplementary service rather than a core business.
The BIM process typically involves completing traditional design first, then adding Revit modeling and analysis or using Revit for error checking across disciplines. Software usage is broader than in construction firms, including Lumion, Fuzor, and specialized Revit plugins, with occasional in-house development. Personnel numbers for BIM roles are higher than on construction sites, with distinct BIM engineers for architecture, structure, and MEP disciplines.
(2) Limitations
Four main limitations affect BIM use in design institutes:
Process Constraints: BIM tasks are often appended after traditional design, mainly for error detection and minor optimizations. This approach limits BIM’s influence on conceptual design or fundamental process improvements, reducing it to a tool for 2D design refinement and presentation.
Application Depth: BIM use remains shallow, focusing on modeling and simple analyses. Potential for advanced uses like green energy performance, seismic analysis, and structural optimization remains untapped. Secondary development efforts tend to prioritize modeling and visualization enhancements rather than deeper functional integration.
Profitability Challenges: BIM-related services command low fees, with modeling costs dropping from 10–12 RMB per square meter to just a few cents in some areas. Some reputable firms maintain higher prices, but overall profitability is limited, making BIM a challenging investment. Nonetheless, design institutes cannot ignore BIM as it is increasingly essential.
Usage Habits: Older designers often lack proficiency with software like Revit, while younger designers may be technically skilled but lack practical engineering experience, limiting effective BIM adoption.
3. Owners
Owner perspectives vary by property type and BIM engagement:
(1) Residential-Focused Owners: Companies like Vanke express interest in BIM but face internal resistance, especially among middle and lower management, who perceive limited value. BIM application is often misguided, focusing on residential building construction, which is already mature and less suited to BIM benefits. Instead, BIM should target the construction, operation, and management of supporting facilities and resident services.
(2) Commercial Real Estate Owners: Entities like Longfor are similarly hesitant. While BIM’s value during construction may be unclear, it holds significant potential for commercial property management and operation.
(3) Landmark and Large Public Building Owners: Examples include Shimao CITIC and government bodies, which are generally more receptive to BIM. However, the extent of BIM’s adoption depends on technical capacity, subcontractor restrictions, and leadership support.
(4) Other Property Owners: Sectors like industrial and elderly care real estate have yet to adopt BIM but could benefit greatly from its application.
4. Consulting Firms
The consulting sector is growing rapidly, with two main categories:
(1) Platform Consulting Firms: Companies such as RIB, Swell, Guanglian Da, Luban, Blue Planet, Autodesk, and Bentley develop BIM software or platforms, each with specific focuses. Chinese firms have made notable progress, for example, Blue Planet integrates BIM with GIS, Guanglian Da focuses on BIM and cost management, and Sver develops BIM education software. These companies deserve recognition and support to further globalize.
(2) Non-Platform Consulting Firms: These firms primarily offer BIM modeling, related visualizations (e.g., walkthroughs, scheduling), and enterprise training. They face challenges similar to construction companies, including a lack of personalized development, leading to homogenized projects and limited innovation. Most rely on standard software, limiting their technological depth and differentiation.
5. Government
(1) Current Situation
Governments at all levels actively promote BIM, issuing policies and requiring BIM use in bidding. Their efforts have significantly increased BIM adoption rates.
(2) Limitations
Four key issues constrain government BIM promotion:
Poor Standardization and Localization: Many local officials and enterprises lack BIM understanding, hindering effective leadership in BIM promotion. Local standards often copy national guidelines without adapting to regional contexts.
Insufficient Marketization of BIM Standards: While government-driven standardization is necessary, pricing for BIM consulting should be market-driven. Current price controls, such as Shanghai’s 10 RMB per square meter standard, do not reflect actual low-cost market realities. The government should focus on contract standardization, performance assurance, and penalty enforcement rather than price setting.
Inadequate Training: Many government and enterprise personnel lack BIM knowledge, and government-led training and interaction initiatives are limited. BIM seminars often lack government participation, reducing their impact.
Insufficient Overall Planning Promotion: Although initial government efforts to raise BIM awareness and develop standards have been effective, there is a lack of clear guidance on BIM application depth and long-term goals. This leaves the industry uncertain about BIM’s future direction.
China’s BIM promotion must follow its unique path, considering its vast territory, numerous enterprises, and population size. Lessons from the UK’s success, characterized by SME dominance and manageable scale, cannot be directly applied. Future suggestions will be shared in subsequent articles.
6. Educational Institutions
(1) Current Situation
In Mainland China, universities are increasingly focusing on BIM teaching and research, with top contributors including Tsinghua University, Tongji University, Huazhong University of Science and Technology, Tianjin University, and Chongqing University. Courses on BIM introduction and software use are growing but still lag behind research efforts.
Initiatives like Professor Ma Zhiliang’s BIM teaching development plans and the upcoming 2015 China University BIM Technology Promotion and Application Exchange Conference demonstrate progress. Meanwhile, BIM teaching in the US and UK integrates BIM into majors and research labs, with leading institutions emphasizing both teaching and research.
Recently, students from several universities formed the “University BIM Alliance,” aiming to include participants from Hong Kong, Singapore, Europe, and the US. Students from Tsinghua University are especially welcome to join.
(2) Limitations
The main challenges in universities include:
Conceptual Misunderstanding: BIM is often taught narrowly as modeling and clash detection, limiting students’ broader understanding.
Programming Neglect: Despite BIM’s integration with computing, most civil engineering programs overlook programming skills, except for a few institutions.
Software Learning Gaps: Students largely rely on self-study for BIM software, with limited curriculum integration.
Lack of Comprehensive Skill Development: BIM talent requires engineering experience, software proficiency, communication skills, and innovation capabilities, which current training programs insufficiently address.
Summary of Common Issues Across Sectors
Conceptual Misunderstanding: BIM is often reduced to VDC or just modeling and clash detection, limiting its development.
Insufficient Application Depth: BIM models can support advanced analyses like seismic and green building performance, yet these are underutilized.
Neglect of Programming and Development: Limited programming skills restrict personalized BIM solutions, and most plugins focus on modeling and visualization rather than deeper functionalities.
Talent Development Mechanisms: Effective BIM talents need diverse skills beyond software operation, including practical experience, communication, and innovation. Current training mostly covers basic BIM concepts and software use.
Model Detail Insufficiency: Shallow BIM models fail to detect many design issues present in 2D drawings.
Unchanged BIM Integration Process: BIM tasks are often tacked on after traditional design workflows, missing opportunities for full process transformation.
