How is Installation Torque Monitored to Ensure Structural Integrity?
Installation torque is monitored in real time to verify that each helical pier achieves the required load-bearing capacity and structural integrity. The monitoring process involves several technical steps:
- Measurement Tools: A pressure transducer is placed inline with the hydraulic system. This device converts hydraulic pressure into torque output, providing continuous measurements during the driving process.
- Data Recording: The torque values are typically captured by a datalogger or electronic torque recorder. This creates a detailed installation report for every pier on a project.
- Correlation to Capacity: These recorded torque values are correlated to the pier’s load capacity using methodology defined in ICC-ES Acceptance Criteria AC358. This ensures the pier reaches the specific design load required by the structural engineer.
- Quality Assurance: A network of structural engineers reviews these torque logs to confirm the installation aligns with design specifications. Real-time monitoring allows crews to identify and adjust for deviations immediately, ensuring no pier is left under-driven.
Following these standards ensures that the helical piers—which engage soil in both compression and tension—provide a reliable and code-compliant foundation repair solution.
