Q: What are some key bridge monitoring projects by Encardio Rite?

Significant projects include: Harry W. Nice Memorial Bridge (strain gauges, tilt meters, crack meters), I-78 Easton Road Bridge (inclinometers, extensometers), Stonecutters Bridge (inclinometers, piezometers), Bogibeel Rail-Cum-Road Bridge (strain gauges, inclinometers, piezometers), and Central Kowloon Route (inclinometers, piezometers, strain gauges).

Q: How is AI used in modern bridge monitoring systems?

AI enables predictive maintenance by identifying patterns in data that indicate potential issues. Encardio Rite is incorporating AI to enhance predictive maintenance capabilities, allowing engineers to address concerns before they become critical.

In January 2018, Colombia's Chirajara Bridge collapse during construction became a wake-up call for civil engineers worldwide. It highlighted the catastrophic consequences of inadequate bridge monitoring and maintenance. The failure, which resulted in multiple fatalities, was traced to design flaws and a lack of continuous monitoring that could have provided early warnings. Such incidents are a stark reminder of the importance of proactive bridge monitoring in preventing disasters.

At Encardio Rite, we understand that bridge monitoring plays a critical role in ensuring the safety, integrity, and longevity of infrastructure. With the rise of new technologies, our monitoring systems are equipped to provide real-time data, enabling rapid interventions and preventing catastrophes like the Chirajara collapse.

Understanding Bridge Monitoring: Why It Matters

Bridges face several critical risks throughout their lifespan. Monitoring enables us to track the following issues:

Scour: Scour occurs when water flow erodes soil around bridge foundations, compromising stability. According to a study by the American Society of Civil Engineers (ASCE), scour is the leading cause of bridge failure in the United States. To mitigate this, scour monitoring systems use sonar-based sensors to measure erosion depth and alert engineers before structural integrity is compromised.

Corrosion: Over time, materials like steel are prone to oxidation, which reduces load-bearing capacity. Corrosion monitoring systems, equipped with electrochemical probes, track corrosion rates in real-time, enabling engineers to take preventive measures before structural degradation occurs.

Excessive load impacts: Unanticipated heavy loads from traffic, seismic activity, or extreme weather can induce stresses beyond design thresholds. Engineers monitor these impacts through load and strain gauges, allowing for load adjustments and maintenance scheduling to avoid catastrophic failures.

These risks, if left unchecked, can lead to severe structural failures and even catastrophic collapses. Our bridge monitoring helps detect early signs of distress, enabling timely maintenance and minimizing risks to public safety.

Structural Health Monitoring (SHM) involves collecting data on parameters like stress, vibration, inclination, and temperature, ensuring engineers can make informed decisions about maintenance and operations. Bridge monitoring improves both the safety and the lifespan of infrastructure.

Encardio Rite's Bridge Monitoring Technologies

At Encardio Rite, we offer a comprehensive suite of advanced bridge monitoring technologies designed to address a wide range of challenges.

Scour and Corrosion: Known as "silent threats" to bridge stability, scour and corrosion are among the primary causes of bridge failure, particularly for bridges with foundations in or near water bodies. Scour occurs when the soil around the foundation erodes due to water flow, weakening the support structure. Corrosion, on the other hand, deteriorates the steel components, compromising the bridge's load-bearing capacity.

Scour monitoring systems: Magnetic and sonar sensors provide reliable solutions for monitoring scour depth around bridge foundations. These sensors can detect changes in the soil and provide real-time updates to prevent failure due to foundation erosion.

Corrosion monitoring systems: Embedded probes provide real-time data on the rate of corrosion in critical structural components. By continuously monitoring corrosion levels, engineers take timely actions to protect the bridge's integrity.

Instrumentation:

Piezometers: Piezometers monitor groundwater levels and help assess foundation stability, particularly in bridges with underwater supports.

Inclinometers and Extensometers: These instruments are crucial for tracking lateral and vertical displacements, helping to identify any unwanted shifts in bridge components.

Tilt Meters and Strain Gauges: Tilt meters monitor deck and truss movement, while strain gauges measure the internal stresses experienced by bridge components.

GNSS (Global Navigation Satellite System): GNSS sensors monitor the precise position of bridge components, allowing for real-time detection of any structural shifts or movements.

Laser Scanners and Total Stations: Laser scanners and total stations provide accurate geometric data of bridge components, enabling precise monitoring of deformations or misalignments.

Accelerometers: Accelerometers measure the vibration levels of bridges, which can indicate their dynamic responses to loads such as traffic or seismic activity.

Data loggers and RF dataloggers: High-speed data loggers and RF dataloggers help in effective data collection and transmission. These ensure that monitoring data is efficiently collected and transmitted, even in remote or harsh conditions.

Real-time alerts and remote access through Proqio: Proqio, our infrastructure data intelligence platform, aids in remote monitoring and real-time alerts. Proqio offers enhanced capabilities over traditional web-based systems, enabling engineers to access, visualize, and analyze data from any location and respond immediately to detected anomalies.
