How to protect underground utilities during construction

Underground utilities are the unseen backbone of public infrastructure. Even though we do not see them, numerous underground utilities are integral to our everyday lives. From stormwater drains to fiber-optic cables, they all lie under the ground. So, whether building a small wall or a big condominium complex, these utilities must not be damaged at any cost.

This article explains how to protect underground utilities during the construction process. It provides an overview of how underground utility mapping can help civil engineers see the underground utilities. Consequently, engineers can ensure that the subsurface utilities are not damaged during construction work.

Using underground utility mapping software

Utility mapping software is a geo-mapping tool that locates the different buried utilities, such as power lines, water mains, gas pipes, electric cables, etc. This subsurface utility engineering tool processes the GPS data, GIS data, and data from utility companies. As a result, all the data are combined to represent the underground utilities visually.

The mapping software creates 3D models and shows the utility lines’ depth, type, and location. Consequently, it helps the engineers note the utility location and avoid underground utility damages.

Underground utility mapping in pre-construction

Before commencing the work, the construction team needs to know where the utilities are and what the risk levels are. They must also be equipped with the right tools and informed about the construction.

Surveying the underground utilities

One cannot envision the construction without assessing the utilities and their locations. An initial site survey must be conducted first. So, utility mapping software can be used to identify underground utilities. The GIS underground mapping software uses different methods and devices, such as GPR (Ground-Penetrating Radar), electromagnetic locators, and cable and pipe locators. It helps to find the accurate location of the different utilities.

Before the excavation, all existing utility data should be collected and uploaded into the software. It may include records from utility companies, previous construction blueprints, and official maps. The software can then integrate this data to produce an accurate utility map of the site.

Designing a utility map

Utility mapping software helps construction professionals create 2D and 3D maps of underground utilities. These maps display multiple layers of information. The different utility lines are shown as per the designated color codes. The site engineers can also see the precise locations and distances relative to the construction area.

This information is crucial for project managers as they decide on excavation zones, equipment use, and construction plans. Visualizing the utilities in 3D allows teams to avoid clashes between utilities and construction operations.

Collaborating with utility providers

Subsurface utility mapping requires collaboration with utility companies, helping them create a comprehensive map of the subsurface utilities. The map can be shared with stakeholders, such as site engineers, contractors, and utility providers. In addition, the GIS underground mapping software integrates with the cloud for real-time collaboration and updates. It ensures that everyone involved in the project can access accurate and up-to-date utility information.

Underground utility mapping during construction

Once construction has started, monitoring the excavation and utility status is important. The utility software should be constantly updated so that no one misses critical updates.

Ongoing monitoring and updates

Construction sites are dynamic, and changes can occur quickly. It is preferable to update the utility map regularly throughout the construction process. Utility mapping software enables real-time monitoring of the site. Changes to utility locations, equipment positioning, or excavation zones can be immediately reflected in the map, minimizing the risk of surprises, such as discovering an unexpected utility line.

Utility mapping software can also alert workers when excavation activities are near sensitive utilities, ensuring workers can take extra precautions.

Using safe excavation techniques

Even with detailed utility maps, excavation near underground utilities should be done with extreme care. Utility mapping software can provide precise coordinates of the utilities. As a result, workers can use that data and excavate carefully without causing any damage. Specifically, they can dig manually or use safer excavation techniques like vacuum excavation. Using this software and proper digging techniques dramatically reduces the risk of accidentally striking a utility line.

Compliance and documentation

Utility mapping software often includes features for documenting utility locations and conditions. Complying with different standards and providing a utility record is important for future maintenance and construction activities.

Marking utility locations on-site

Transferring information from digital utility maps to the physical world is essential for safe and effective construction. This process typically involves converting the data from digital utility maps into tangible markers, such as flags or painted lines on the ground. These markers serve as visual cues for the location of underground utilities.

Once the physical markers have been placed, all the team members must be fully aware of the utility locations and associated hazards. This awareness ensures safe operations and prevents costly accidents.

Utility mapping in post-construction

Once the construction is completed, verifying that all utilities have remained intact is crucial. Utility mapping software can be used to conduct a final site inspection. In fact, the software can be used to compare the pre-construction utility map with the current layout. If any discrepancies or damage are detected, immediate repairs can be made to prevent long-term issues. Maintaining accurate records of utility locations is important for future construction projects or maintenance work.
