Enabling Technologies for Digital Twins of Underground Infrastructure by Dr Jelena Ninic
1. Traditional Methods
For years, American cities have leaned on conventional strategies to manage underground infrastructure. While these methods have been the backbone of modern engineering, they now struggle to meet the demands of increasingly complex urban landscapes. Let’s take a closer look at where these traditional approaches fall short.
Data Accuracy
Traditional systems rely heavily on static CAD drawings, paper records, and GIS systems, which often falter due to sensor limitations and environmental factors. The result? Positional errors that can vary from a few inches to several feet. In fact, studies reveal that up to 30% of underground utility strikes in the U.S. stem from inaccurate or missing location data. The problem becomes even more pronounced with older infrastructure, where as-built drawings may be incomplete - or missing entirely. These inaccuracies slow data updates and, in turn, delay critical response times.
Response Time
Updating data using traditional methods is a slow process, often taking days or even weeks. Emergency situations are particularly impacted, as manual surveys require on-site visits, data reconciliation, and exploratory digging (known as potholing) just to confirm utility locations. Without accurate as-built records, service disruptions are more likely, and repair times stretch longer than necessary.
Cost Efficiency
Manual data collection isn’t just slow - it’s also expensive and prone to human error. According to the Common Ground Alliance, utility strikes cost the U.S. economy over $30 billion annually, with much of that attributed to incomplete or inaccurate subsurface data. Traditional CAD and GIS systems often produce information that isn’t immediately usable for asset management or real-time decision-making. This inefficiency is especially evident during transitions from design to construction to operation, where data loss frequently occurs. One glaring example is Boston’s infamous “Big Dig” project, where incomplete utility records caused unexpected discoveries, leading to delays, cost overruns, and safety hazards.
Safety
Outdated methods also increase safety risks. Accidental utility strikes can lead to injuries, fatalities, and property damage. Relying on old records and manual excavation heightens the risk of encountering unknown utilities. The Occupational Safety and Health Administration (OSHA) highlights excavation and trenching as some of the most dangerous construction activities, with many incidents tied to poor subsurface data. Since traditional approaches are largely reactive and inspections happen infrequently, critical issues often remain hidden until they escalate into serious problems.
Collaboration
Another major drawback of traditional methods is the lack of effective collaboration. Data silos prevent seamless coordination between geologists, engineers, and asset managers, who often work from outdated plans or rely on verbal updates. This can lead to miscommunication, project delays, and inconsistent information. Without a centralized, real-time data platform, large or complex projects suffer from fragmented decision-making. Additionally, during emergencies, the inability to share accurate information quickly can slow down response efforts and complicate coordination among multiple utility owners.
2. Digital Twin Solutions
Digital twin technology creates dynamic, real-time models that continuously update using sensor data. Unlike older methods that often suffer from fragmented information, digital twins provide a unified and accurate view of subsurface conditions.
Data Accuracy
By combining real-time sensor inputs with Building Information Modeling (BIM), digital twins create a continuously updated system, significantly improving data precision. This integration results in comprehensive asset maps, leading to 30% more detected defects compared to traditional inspection methods.
A great example of this comes from a major Italian tunnel network project covering 2,500 kilometers. Tecne Systra used a digital twin solution that incorporated data from borehole cameras, core drilling, and other tools. This approach improved survey data interpretation by 30%, enabling more precise decisions throughout the project lifecycle.
Platforms like Anvil Labs enhance accuracy further by hosting diverse data types - such as 3D models, LiDAR point clouds, thermal imagery, and orthomosaics - in one unified system. With customizable tools for viewing and measurement, these platforms ensure a higher level of precision, ultimately improving system performance.
Response Time
Digital twins excel at instant detection and diagnosis, eliminating delays caused by manual surveys. With continuous data streaming from sensors, teams can identify issues like leaks or outages as they happen, cutting down service disruptions. This real-time responsiveness was a key factor in speeding up project delivery.
Cost Efficiency
The financial advantages of digital twins come from simplifying data integration, reducing modeling time, and improving project coordination. For instance, the Italian tunnel rehabilitation project saw a 25% reduction in modeling time and a 30% faster clash detection rate thanks to digital twin technology. According to KPMG, using digital twins for structural health monitoring can lower maintenance costs by 20% while helping to prevent catastrophic failures. Predictive maintenance features also allow teams to schedule repairs efficiently, minimizing unplanned outages and extending the lifespan of critical assets.
Safety
Safety is another area where digital twins shine, offering up-to-date overviews of underground conditions that reduce the risk of utility strikes and hazardous exposures. Drone-based data collection further enhances safety by limiting the need for personnel to enter dangerous environments for inspections. Remote assessments enable thorough evaluations without putting workers at risk. Additionally, digital twins can simulate disaster scenarios - like earthquakes or floods - helping organizations plan and implement proactive risk mitigation strategies.
Collaboration
Digital twins don't just improve technical metrics - they transform how teams work together. These platforms break down data silos by creating shared, interactive 3D environments accessible to all stakeholders. Engineers, geologists, designers, and decision-makers can collaborate using the same up-to-date information, reducing miscommunication and improving coordination. The Italian tunnel project highlighted this capability, allowing multidisciplinary teams to work seamlessly in real time within a unified digital environment.
Platforms like Anvil Labs enhance collaboration further by offering centralized data storage, secure sharing options, and cross-device accessibility. They also integrate AI analysis and task management systems, ensuring every team member stays connected and informed.
