Following Part 1, which explored IoT's impact on bridges, dams, and tunnels, this continuation focuses on pipelines, mining operations, and high-rise buildings. These infrastructure types present unique challenges—vast, vertical, and often hidden from view. IoT is proving indispensable in these domains, delivering insights that were once inaccessible. From acoustic sensors in pipelines to smart concrete in skyscrapers, this blog highlights emerging innovations and industry use cases that go beyond common IoT narratives. If you missed Part 1, you can read it for foundational context on structural monitoring in transportation and hydraulic infrastructure.

Pipelines: Real-Time Leak Detection and Structural Intelligence
Pipelines span thousands of kilometers, often buried or underwater, making them difficult to inspect physically. IoT is overcoming this challenge with distributed sensing systems. Fiber-optic cables running alongside pipelines now act as continuous sensors, detecting strain, vibration, and acoustic changes along their length. These systems can pinpoint a leak or physical disturbance within meters. For instance, companies like OptaSense and DNV have successfully implemented fiber-based monitoring in oil and gas pipelines to detect tampering, leaks, or land shifts in real time (DNV). A report by DNV showed that distributed acoustic sensing (DAS) can detect pipeline leakage events down to a few liters per minute and pinpoint leak locations within 10 meters under field conditions.
In municipal water systems, acoustic sensors and pressure loggers placed inside pipe networks communicate wirelessly to detect small leaks before they become catastrophic. SmartWater, an initiative in the UK, uses AI-driven interpretation of sensor data to predict burst risks and prioritize repairs. According to a case study by Yorkshire Water and Siemens, the implementation of real-time pressure monitoring led to a 25 percent reduction in bursts in the pilot region (Water Online).
A study published in the journal Sensors (2020) titled "Smart Water Pipeline Monitoring and Leakage Detection Systems: A Review" emphasized that combining IoT with machine learning offers the highest accuracy in leak detection by analyzing pressure drop and flow imbalance trends across distributed nodes (Sensors Journal).

Mines: Subsurface Safety Through Sensing
Mining presents some of the most complex monitoring environments, including slope stability, groundwater pressure, and air quality. Open-pit mines use IoT-enabled inclinometers and extensometers to detect wall movement and prevent collapses. Underground, sensors monitor gas levels, humidity, and seismic activity to warn of unsafe conditions.
One standout example is from a Canadian gold mine using IoT-connected piezometers and radar to track tailings dam conditions. The sensors continuously transmit readings to a central platform, enabling compliance with global standards like the Global Industry Standard on Tailings Management (GISTM). Their system detected abnormal pore pressure buildup prior to rainfall, prompting drainage system activation and averting a slope failure.
The World Bank’s 2021 “Mine Tailings Storage: Safety Is No Accident” report also recommends IoT monitoring systems as essential for early warning. It references how multiple operations in Brazil and Peru now integrate remote geotechnical surveillance into central risk dashboards (World Bank Report).
Another study from the International Journal of Mining Science and Technology demonstrated that IoT-based microseismic monitoring systems in deep underground mines achieved 94 percent event detection accuracy in lab-to-field transition tests, providing life-saving lead time during roof-fall events (IJMST Study).
High-Rise Buildings: Smarter from Foundation to Façade
In high-rise construction, IoT enables real-time monitoring of concrete strength using wireless maturity sensors. For instance, Giatec’s SmartRock sensors embedded in concrete during pours provide mobile updates on curing status. According to Giatec’s validation trials, SmartRock readings predicted compressive strength with over 90 percent accuracy compared to lab-tested cylinders, enabling safe formwork removal up to 24 hours earlier on some projects.
Post-construction, buildings like the Shanghai Tower integrate hundreds of sensors—strain gauges, tiltmeters, GPS units—feeding data into a central structural health platform. In a detailed study published in Structural Monitoring and Maintenance journal, researchers outlined the Shanghai Tower’s SHM system of 632 sensors, which recorded wind-induced responses across multiple floors. The system detected maximum sway at the top floor up to 1.3 meters during Typhoon Lekima in 2019 and verified the structure’s aerodynamic damping design.
IoT is also enabling real-time control: data from sensors informs building management systems (BMS) and adjusts dampers, lighting, and HVAC systems dynamically. The integration of SHM and building automation systems was demonstrated in a pilot project by Skanska in Sweden, where IoT data improved energy efficiency by 18 percent and flagged HVAC faults before user complaints, as documented in the Energy and Buildings journal.

A Systemic Shift in Civil Infrastructure Management
This post is the second half of our two-part series on IoT in civil engineering. If you haven’t read Part 1, it covers IoT applications in bridges, dams, and tunnels—including case studies from Scotland’s Queensferry Bridge and California’s Bullards Bar Dam. Together, both entries offer a comprehensive look at how civil infrastructure is being transformed by real-time data technologies.
As we have seen in pipelines, mines, and high-rises, the role of IoT is not just in sensing but in decision-making, safety, and operational continuity. The future will likely see wider use of digital twins, AI-driven diagnostics, and energy-harvesting sensors that eliminate battery reliance. As more assets become smart, civil infrastructure is evolving from static and silent to dynamic and communicative, reshaping how cities and industries manage risk and resilience.
FAQs
1. How does IoT help detect leaks in pipelines?
IoT systems use acoustic sensors, pressure loggers, and fiber-optic sensing to identify abnormal vibration or pressure changes. These signals help locate leaks early, often within a few meters, before visible damage occurs.
2. What is distributed acoustic sensing (DAS) in pipeline monitoring?
DAS uses fiber-optic cables as continuous sensors along a pipeline. It detects sound and vibration changes caused by leaks, third-party interference, or ground movement in real time.
3. Why is IoT important for mine safety monitoring?
Mining environments involve slope instability, groundwater pressure, gas buildup, and seismic risks. IoT enables continuous monitoring of these parameters, helping operators issue early warnings and prevent accidents.
4. How are IoT sensors used in tailings dam monitoring?
Wireless piezometers, inclinometers, and weather sensors track pore pressure, deformation, and rainfall. Real-time data allows operators to respond quickly to unsafe conditions and meet safety standards.
5. Can IoT systems work in deep underground mines?
Yes. IoT sensors designed for harsh environments can operate underground using wireless mesh networks, low-power communication, and rugged enclosures suitable for mining conditions.
