BIM technology benefits underground construction by improving safety, contextualizing underground structures, and promoting more sustainable construction practices.
FREMONT, CA: Underground construction technology is becoming more sophisticated and dynamic than ever before, especially due to advancements in building information modeling (BIM). Working around buried buildings and components is difficult by nature, but BIM provides opportunities to make it much safer, more efficient, and more understandable.
Contextualizing underground structures: The most obvious advantage of using BIM construction technology is the ability to integrate underground constructions into the larger context of their surroundings. BIM is already a popular technique for visualizing and creating above-ground buildings, but incorporating below-surface components into the images clearly represents the project from top to bottom. Underground components must integrate with and adapt to the needs of the primary structure above them. Including them in the project's BIM ensures that everything is considered in the design. After all, some of the structure's most critical components, such as water lines, are buried.

Enhanced safety: One of the most crucial advantages of BIM in the construction process is its capability to undertake risk analysis. Engineers and risk managers may examine the entire structure using advanced features such as heat distribution and layered images, making risk analysis a far more thorough and trustworthy procedure. This has a direct impact on the overall project safety. For example, a risk manager may use BIM to automatically identify all locations on the structure that provide a substantial fall hazard to construction workers.
It is also possible to identify specific risks associated with buried buildings. Underground construction imaging technologies, such as LiDAR or GPR, and GIS are especially useful for this procedure. This has already proven tremendously effective in lowering risk with components such as waterline systems.
The data from LiDAR, GPR, and GIS serve as eyes and ears below ground, reducing the need for human team members to risk entering into potentially unstable tunnel systems. Ground-penetrating photography closes the information gap, allowing safety and risk analysis using BIM to be a whole-building assessment.
Improved collaboration: Many construction teams worldwide benefit from BIM's ability to facilitate dynamic communication. BIM integrates various documents that are usually examined individually, including exterior design, HVAC system mapping, and heat distribution studies. Having all this information in one convenient digital format ensures that everyone working on the project can access the most precise and current information.
