Monitoring of infrastructure projects, both during and post-construction, allows key stakeholders to:
· Improve decision making
· Manage risks
· Increase safety
· Increase productivity
· Optimize designs
· Reduce costs
Infrastructure Monitoring – An Overview
- Monitoring systems are an integral component of construction projects that have complex geotechnical challenges, risk to the public or adjacent infrastructure, and when observation methods will be used to confirm design performance. Monitoring can be used on the asset under construction and also on adjacent assets that may be impacted by construction efforts. This is especially applicable in dense urban environments, where surface and sub-surface assets are in close proximity to each other. Infrastructure projects that typically involve monitoring systems include:
- Retaining walls,
- Pile load tests, and
- Geohazards (landslides).
Make Improved Decisions – Benefits of Monitoring Systems
- By implementing instrumentation programs, key stakeholders, such as the asset owner, the engineer of record, and prime and sub-contractors, and adjacent asset owners can monitor geotechnical parameters during construction. If site parameters change during construction or are unexpected in comparison to the project design, action plans can be implemented to mitigate risks to protect public safety and the health of all of the assets involved.
- Instrumentation can be monitored long-term to confirm performance of the structure over time.
- Monitoring instruments provide insight to key areas of concern such as:
- Ground displacement (settlement or lateral movement),
- Groundwater levels, and
- Load, stress and tilt of structures.
The Path to Success – Core Infrastructure Monitoring Components
- Instrumentation, data acquisition and collection should be selected to suit site-specific conditions and stability concerns.
- Instrumentation installations should be designed to answer specific concerns in the structure, including the geotechnical parameters to monitor and the location to install the sensors.
- A variety of data acquisition options are available to meet site specific needs. These can range from manual to fully automated systems.
