Since its introduction to China in 2002, BIM Technology has gradually gained momentum. Initially met with indifference, BIM has evolved over more than a decade and is now widely adopted throughout the industry. Today, both companies and professionals recognize BIM as a vital trend shaping the future of construction and as an essential tool for advancing building industrialization. Despite early challenges and limited profitability from BIM investments, many firms continue to embrace this technology. But why is that? Below, the author explores five key reasons driving the growing application of BIM.
1. The Construction Industry as a Major Energy Consumer
Statistics reveal that the construction sector consumes roughly 40% of the world’s raw materials, positioning it as a significant force in the global economy and geopolitics. Buildings account for about 40% of global energy consumption. In China, building energy use represents approximately 33% of total societal energy consumption, highlighting the industry’s critical role in energy conservation.
Buildings contribute to 40% of global carbon emissions and generate 20% of worldwide waste, underscoring their substantial environmental impact. Clearly, the construction industry must take responsibility for utilizing Earth’s resources more efficiently.
Specifically in China, energy-intensive buildings are prevalent. For instance, northern heating regions consume an additional 18 million tons of standard coal annually, causing a direct economic loss of 7 billion yuan and releasing 520,000 tons of extra carbon dioxide emissions. If this trend continues, China’s building energy consumption is projected to reach 108.9 billion tons by 2020. Furthermore, peak summer air-conditioning demand could match the output of ten Three Gorges power stations—an astonishing figure.
Given these challenges, all stakeholders in the construction industry must urgently maximize value-added services throughout their processes to reduce waste and improve efficiency.
2. Waste Resulting from Fragmentation in the Construction Process
Current efforts to transform the construction industry mainly focus on optimizing design and construction phases. While progress is still needed in these areas, there is growing consensus around adopting a full lifecycle approach. Without embracing sustainability throughout a building’s entire lifecycle, waste will persist at every stage due to existing planning, design, and construction practices.
3. The Construction Industry’s Influence on the Entire Industrial Chain
Within a building product’s relatively short lifecycle, issues such as performance failures, waste generation, recycling costs, energy consumption, and environmental damage may arise. These challenges, combined with industry fragmentation, dependence on foreign oil, trade imbalances, and environmental degradation, pose serious threats to the national economy and security.
To reverse this negative trend and mitigate its effects, the construction industry must act promptly and responsibly.
4. The Critical Importance of Design and Construction Phases
Although design and construction account for only a small portion of a facility’s total lifecycle cost, decisions made during these phases have the greatest long-term impact. Most expenses occur during operation and maintenance, and experience shows that poor planning, design, and construction contribute significantly to high costs in these later stages.
5. Early Involvement of Operations Personnel in Planning and Design
Research indicates that improving efficiency across design, construction, operation, and maintenance can reduce total costs by at least 3.8%. Involving operations personnel early in the planning and design stages clearly enhances the efficiency of facility creation, maintenance, and ongoing operation. Achieving this requires close collaboration among all personnel involved with the facility to optimize processes.
In conclusion, the author has summarized five key reasons for applying BIM technology. However, some points may not fully reflect the realities of China’s construction industry. For example, early involvement of operations personnel may not always be practical, given the common outsourcing of operation and maintenance services in China.
Still, these insights are shared to encourage further discussion. The author welcomes additional comments and hopes to engage in meaningful exchanges on this topic. Thank you.
