Structural Health Monitoring

Pre and post-construction health monitoring refer to the assessment and management of health-related aspects before and after the construction of a project. This involves evaluating potential health risks and implementing measures to safeguard the well-being of individuals in the surrounding environment.

Pre-Construction Health Monitoring:

Soil Moisture Sensors:
Monitor changes in soil moisture to assess potential risks of instability, settlement, or erosion before construction begins. Provide data to design proper drainage systems.
Piezometers:
Measure groundwater levels to understand the hydrological conditions of the site. Identify potential issues related to water ingress during excavation.
Geotechnical Borehole Instruments:
Conduct soil and rock sampling to analyze the composition and strength of subsurface materials. Determine the bearing capacity of the soil for foundation design.
Seismic Monitoring Equipment:
Assess the seismic vulnerability of the site by measuring ground vibrations and potential liquefaction risks. Identify the need for seismic design considerations.
Inclinometers:
Monitor ground movements, slope stability, and deformations in the soil. Identify potential landslide or slope failure risks.
Surveying Instruments:
Use total stations and GPS devices to establish baseline topographic data for the construction site. Monitor any changes in land elevation or settlement during construction.

Post-Construction Health Monitoring:

Structural Health Monitoring (SHM) Systems:
Deploy sensors on structures to monitor changes in strain, deformation, and vibration. Identify potential structural issues or damage caused by construction activities.
Settlement Plates and Rod Extensometers:
Measure vertical settlements and subsidence to ensure that structures are not experiencing excessive movement. Identify any uneven settlement that may pose a risk to structures.
Groundwater Monitoring Wells:
Continue monitoring groundwater levels to assess the impact of construction on local hydrology. Identify potential changes in water quality.
Vibration Monitoring Equipment:
Monitor ground vibrations and ensure that construction activities do not exceed allowable limits. Mitigate the risk of damage to nearby structures or sensitive equipment.
Automated Weather Stations:
Monitor weather conditions, including rainfall, temperature, and wind speed. Assess the impact of weather on the stability of slopes and soil.
Geophysical Surveys:
Conduct post-construction geophysical surveys to identify changes in subsurface conditions. Detect any anomalies or shifts that may affect the stability of the site.
Landslide Monitoring Instruments:
Install instruments like inclinometers and tilt meters to monitor slope stability continuously. Implement early warning systems for potential landslides.

By integrating geotechnical instruments into pre and post-construction health monitoring, project stakeholders can proactively manage risks, ensure the safety of structures, and minimize the environmental impact of construction activities. Regular monitoring and analysis of geotechnical data contribute to the overall success and sustainability of construction projects.
