Currently, BIM is widely adopted by construction companies in China. So, what are the practical applications of BIM in these companies? Let the editor from the BIM Architecture Training Network explain.
First, BIM is used for collision detection, which significantly helps reduce rework. During construction, based on the drawings, collisions between pipelines or between pipelines and structures may be discovered. Traditionally, this involves comparing pipeline design drawings and construction drawings manually to identify clashes. When collisions are found, they must be corrected promptly; if none are found, construction proceeds. However, issues can still arise once construction begins. With BIM technology, all these checks can be performed virtually within the system—simulating construction to detect and eliminate any collisions ahead of time. This process is known as collision detection.
Second, BIM effectively supports quantity takeoff and cost estimation. Using the 3D model, quantities and pricing can be automatically extracted through computer software, streamlining project cost calculations.
Third, BIM assists in the division and planning of the construction process, improving scheduling and workflow management.
Fourth, BIM enables multidimensional information integration, which supports comprehensive project management and control. But what does multidimensional information integration mean? Beyond the 3D model, it incorporates progress data, material information, and safety details. This allows analysis from various perspectives. For example, 4D BIM adds schedule data to the 3D model using specialized software, making it easier to visualize construction progress over time. You can see what the site looks like on the current day, after 20 days, or after 30 days, almost like watching a movie of the construction process.
Additionally, by integrating materials, on-site conditions, and actual progress into the model, real-time statistics become available. For instance, you might view the status of a particular WPS (Work Package Specification), tracking how much has been completed, what is in progress, and what hasn’t started yet. You can also monitor the overall project quantity—how much work is finished, underway, or pending. This comprehensive insight facilitates effective control over the entire construction process.
Fifth, BIM supports virtual assembly. Similar to collision detection, BIM provides a clear sequence for assembling components. The entire construction sequence can be simulated virtually on a computer before actual assembly begins, which is known as virtual construction.
Sixth, BIM aids on-site construction activities. Workers can be trained using the BIM model to familiarize themselves with the site layout. Once on site, they can refer to the model to guide their work accurately.
Seventh, BIM enhances off-site construction activities. Some components need to be fabricated in factories during the construction process. Traditionally, fabrication is based on drawings, which can be difficult to interpret for irregular components. Mechanical processing often requires more than just diagrams; it requires CNC machine tools programmed with BIM data for precise manufacturing.
In summary, these are the key BIM applications within construction companies as outlined by the editor of the BIM Building Training Network. We welcome you to contribute any additional insights.
