BIM is commonly used for visualizing and planning above-ground structures, incorporating below-surface elements into the model, which provides a comprehensive representation of the project and offers a complete view from top to bottom.
FREMONT, CA: The introduction of building information modeling (BIM) has simplified construction processes by allowing the digital representation of buildings in physical and functional terms. While underground construction is complicated and unsafe because of its buried structure and components, using BIM before construction enhances safety by predicting and reducing associated risks. There are several benefits of using BIM during the planning of underground construction, and they have been discussed below:

A significant advantage of implementing BIM construction technology is the seamless integration of underground structures into the overall context of their environment. Although BIM is commonly used for visualizing and planning above-ground structures, incorporating below-surface elements into the model provides a comprehensive representation of the project, offering a complete view from top to bottom.
Underground structures must integrate and adapt to the main structure above them. Hence, including underground construction in the project's BIM is essential, as some of the major components of the construction, like the water pipeline, are constructed below.
Less invasive construction
BIM supports trenchless excavations like micro tunneling, which are far less intrusive and disruptive to the local community and the environment.
Using tools above the ground, information about buried structures or earthworks can be collected. This data can then create a comprehensive digital model, allowing for precise mapping of items such as pipes and tunnels. This proactive approach facilitates a quick and discreet excavation process.
Improved safety
One of the most significant benefits of BIM in the construction process is its ability to conduct risk analysis. It improves safety by analyzing and predicting potential hazards. Technologies like LiDAR and GPR combined with BIM act as below-ground sensors, reducing the need for human visits in unstable areas.
More sustainable construction
In recent years, there has been an increased demand for sustainable construction. Construction processes have a significant impact on the environment, from how materials are sourced to energy consumption on the site. Through BIM, such demand for sustainability can be achieved.
As mentioned earlier, trench excavations are destructive to the surroundings; BIM offers the option of trenchless excavations, enabling sustainable and environment-friendly underground constructions.
Optimized collaboration
Another benefit of BIM is that it allows dynamic collaboration among architects, contractors and designers. BIM brings together various documents such as HVAC systems, exterior design, and heat distribution analysis. All of this information is available in one place in digital form, ensuring everyone is on the same page and has access to up-to-date information, leaving room for little or no error.
