Services
PICO takes on each phase of a geotechnical instrumentation program, engaged as the project requires: the stamped design, field installation of instrumentation, monitoring and maintenance, sensor data display on PICO Monitoring, and licensed engineering analysis.
Instrumentation design
Instrumentation plans prepared and stamped by a licensed geotechnical engineer.
Field installation
Sensors and hardware installed by a licensed contractor, directed by PICO.
Monitoring and maintenance
Sensors and hardware tested and maintained.
Data on PICO Monitoring
Threshold alerts by email and SMS, and dashboard views on PICO Monitoring, custom-built for geotechnical and structural instrumentation data.
Licensed engineering analysis
A licensed geotechnical engineer available to analyze the data, identify risk trends, and deliver actionable engineering recommendations.
PICO Monitoring
Every instrument on the project is viewable on a private project dashboard, with its full history as plots and tables. When a reading crosses a threshold, alerts go out by email or SMS.
