A vibration monitor can produce thousands of measurements. The difficult part is not collecting them. It is deciding what they mean. Construction activities such as piling, vibratory sheet piling, demolition, rock breaking, excavation and tunnelling can generate vibration that travels through the ground and structures. For this reason, construction vibration monitoring is frequently used to… Read more: How Construction Vibration Monitoring Is Interpreted

Piezometers and water standpipes are both used in geotechnical monitoring to understand groundwater conditions. Because both may ultimately produce a result expressed as a water level or hydraulic head, they are sometimes treated as interchangeable. They are not. The distinction becomes particularly important in layered ground, deep excavations and dewatering works where groundwater conditions can… Read more: Piezometer vs Water Standpipe: What Is the Difference?

Deep excavation changes the balance of forces within the ground. As excavation proceeds, an earth-retaining wall may deflect toward the excavation and the surrounding ground may deform. Inclinometer monitoring provides engineers with one of the most useful ways of measuring this lateral movement with depth. In Singapore, lateral ground movement forms part of the instrumentation… Read more: How Inclinometer Monitoring Works in Deep Excavation

Earth Retaining and Stabilising Structures (ERSS) are widely used in Singapore for basement construction, deep excavation, infrastructure works and underground development. During excavation, the retaining system, surrounding ground, groundwater and adjacent structures may all respond to changes in stress and construction sequence. For this reason, an effective ERSS instrumentation and monitoring programme is not based… Read more: Typical Instrumentation for ERSS Monitoring in Singapore
