FOUNDATION TESTING

Foundation testing is conducted to ensure physical integrity and load-bearing capacity of driven or bored piles before building structures are erected.

Foundation Testing

Geotechnical & Foundation Services

Professional and accurate integrity and load capacity testing for foundation piles, fully compliant with construction technical specifications.

Objective:
  • Inspect continuity and integrity of the pile along the testable depth.
  • Identify indications of damage such as cracks, necking, cross-sectional changes, or non-homogeneous material.
  • Ensure pile installation quality aligns with design and technical specifications.
  • Provide supporting data for foundation condition evaluation prior to the next construction stage.
Scope of Services:
  • Review and verification of pile testing data.
  • Preparation of the pile head surface.
  • Execution of testing using the Low Strain Integrity Test method.
  • Acquisition and recording of wave responses from the pile.
  • Signal analysis and test result interpretation.
  • Identification of anomalies or irregularities in the pile.
  • Preparation of test reports and technical recommendations.
Requirements / Preparedness:
  • Pile layout drawings and pile schedule.
  • Diameter, length, and pile type data.
  • Material data and pile installation method.
  • Pile heads must be fully exposed and accessible.
  • Pile head surface must be sufficiently flat and clean for sensor attachment/impact.
  • Safe and easily accessible workspace for the testing team.
  • Information regarding schedule and actual site conditions.

Objective:
  • Evaluate axial pile capacity during the driving process.
  • Assess pile response and behavior under driving energy.
  • Estimate ultimate and allowable bearing capacity based on dynamic analysis.
  • Check driving system efficiency and energy transferred to the pile.
  • Identify potential overstressing or damage to the pile during driving.
  • Provide supporting data to ensure driving operations meet design requirements.
Scope of Services:
  • Review of design data and driving methods.
  • Inspection of type, size, and specifications of piles and hammers.
  • Installation of strain transducers and accelerometers on the pile.
  • Real-time monitoring of driving parameters.
  • Recording of force and wave velocity during driving.
  • Data analysis using Case Method and/or CAPWAP as required.
  • Evaluation of pile capacity, hammer energy, and driving stresses.
  • Preparation of test reports and technical recommendations.
Requirements / Preparedness:
  • Structural/foundation drawings and pile layout.
  • Pile schedule and specification data.
  • Material data, dimensions, and pile length.
  • Hammer data used, including type, weight, energy, and driving configuration.
  • Driving method and sequence data.
  • Soil investigation/geotechnical report, especially SPT/CPT and soil parameters.
  • Heavy equipment access and safe working area.
  • Piles must be ready for instrumentation and testing.
  • Operators and piling crew available during testing.
