FOUNDATION TESTING AND MONITORING

Continuous Pile Monitoring

• Continuous pile moitoring can be done by PDA test

Instrumented Pile Load Tests

• Fiber optic strain sensing technology can be applied for instrumented pile load test.
• The continuous strain profile throughout the pile during the load test will provides a detail insight of the test pile capacity and performance.
• The fiber optic system can be installed in bored piles, spun piles, R.C. piles etc, for conventional Maintain Load Test (Kentledge or Reaction System), Bi-Directional Static Load Test and Lateral Load Test.

Pile Raft Monitoring

• Long term integrity monitoring of pile raft foundation using strain and temperature optical based sensor.

Soil Nail Instrumentation

• Instrumented Pull Out Test.
• Long Term Slope Monitoring

Road

Dynamic monitoring for the displacement of road performance assessment subjected to traffic load. Distributed Fibre Optic Strain Sensing Sensor and Fibre Bragg Grating Sensor can be used to monitor:

• Magnitude of load or pressure transferred down to subgrade
• Vertical land subsidence and influence depth below the road
• Long term road performance 

Airport Runway

A series of Fibre Bragg Grating Sensor can be installed in the boreholes to identify changes in different subgrade layers of borehole. Hence, dynamic monitoring for the airport performance assessment subjected to traffic load can be obtained. 

• FBG Extensometer to monitor displacement of the subgrade
• FBG Piezometer to monitor water pressure
• Long term airport runway performance
