The Application, Value, and Experience of BIM in Construction Engineering
In recent years, Building Information Modeling (BIM) technology has rapidly advanced and gained widespread adoption within the global construction industry. China, following this trend of integrated building information, is actively embracing BIM technology. The growing demand for BIM in public infrastructure projects has made its adoption an inevitable industry trend.
Domestic public works contracts in China increasingly require the implementation of BIM technology. Many practical experiences have been accumulated, and the Public Works Commission has established a BIM promotion platform. The goal is for project organizers and industry professionals to quickly become proficient with BIM, achieving cost reduction, shorter construction timelines, and improved quality—aligning with international engineering standards.
Benefits of BIM
Based on years of hands-on experience, BIM offers numerous advantages: it enables intuitive and visual decision-making, serves as an effective communication tool between professionals and non-experts, enhances design and construction reliability, reduces drawing costs during design and construction phases, ensures accurate scheduling, and opens opportunities for industry-wide innovation.
Most owners or investors in China’s construction sector lack architectural or engineering backgrounds. Traditionally, architects and designers would present complex designs using two-dimensional drawings and material samples, requiring owners to imagine the final building with limited information. This approach introduces uncertainty into their decision-making process.
This often results in lengthy, repetitive decision-making or outcomes that differ significantly from initial expectations once construction is complete. Throughout a building’s lifecycle, its development can be categorized into five stages based on the Level of Development (LOD): planning proposal (LOD 100), preliminary design (LOD 200), detailed design (LOD 300), construction (LOD 400), and operation (LOD 500).
When BIM is implemented, the design concepts applied at each stage remain consistent with traditional methods. However, BIM replaces traditional 2D drawings with a collaborative 3D platform, allowing for direct design, communication, and integration within a shared 3D model. Unlike traditional workflows, where mechanical and electrical designs were separate and sometimes unclear in structural drawings, BIM integrates all information on a single platform, improving clarity and coordination.
Architects often review designs from perspectives uncommon to the human eye, such as aerial or distant views. While useful, it is equally important to assess the building’s appearance and interior from the viewpoint of a human observer to avoid surprises like discovering a building is situated in a narrow alley post-construction, which can distort perception.
Although BIM technology was introduced early in China’s civil engineering sector, many business owners were initially reluctant to invest in R&D before its strong promotion. As public projects mandated BIM adoption, construction firms had to allocate resources to establish BIM departments and capabilities. This shift highlights China’s commitment to advancing the BIM industry.
China has accumulated significant case studies and practical experience with BIM, but its influence across the entire industry supply chain remains limited. For example, different manufacturers must repeatedly model the same equipment independently, often using inconsistent methods. These models can be costly, and manufacturers treat them as proprietary assets, unwilling to share freely.
To address this, China could establish unified modeling standards and provide common free models via industry associations for public use. This would standardize modeling practices and prevent redundant resource expenditure.
BIM Personnel and Talent Development
The overall experience of domestic BIM professionals is still limited, and talent development requires time. Most BIM engineers currently serve in supporting roles rather than leading projects. Site supervisors often lack understanding of BIM, treating it merely as an owner’s requirement without engagement.
Construction companies should adopt a long-term perspective rather than seeking quick wins. Cultivating skilled BIM engineers gradually will yield substantial benefits for the company and project outcomes.
Integration of Civil Engineering, GIS, and BIM
The integration of Geographic Information Systems (GIS) with BIM in civil engineering is progressing slowly. Civil engineering projects cannot rely solely on private sector efforts to build comprehensive BIM models. China needs to promote three-dimensional digitalization of both new and existing buildings promptly to avoid situations like the lack of underground pipeline data, which contributed to the severity of the Kaohsiung gas explosion.
In conclusion, understanding the application, value, and practical experience of BIM in construction engineering is essential for advancing the industry. I hope this article provides useful insights for everyone interested in BIM technology.
