Accurate and thorough documentation is the backbone of a reliable helical pile installation. As The Experts in Steel Piers, we prioritize recording the torque-to-capacity correlation for every pier we install because it provides immediate, real-time verification of foundation performance. This documentation creates a permanent record for engineers and property owners, ensuring every shaft meets design specifications.

To ensure your project meets ASCE and ICRI standards, we recommend following these documentation best practices:

• Record the Terminal Torque: Our certified installers record the final installation torque reading (measured in ft-lbs) for each pier once it has advanced into the competent bearing strata.
• Document the Kt Factor: The Kt factor is an empirical multiplier specific to the pile shaft geometry used to convert installation torque into an estimated capacity. We meticulously document the precise factor used for each pile shaft on our installation logs.
• Maintain Comprehensive Pile Logs: Each log should include the pile depth, the terminal torque, the calculated predicted capacity (using the formula Qu = Kt x T), and the specific soil characteristics observed.
• Provide a Master Closeout Package: All gathered data should be compiled into a project closeout package and shared with the general contractor and engineer of record for final approval.

Our team has been family-owned and operated since 1996, and we maintain these rigorous standards to provide traceable, long-term accountability for every residential and commercial project. Please note that all estimates are preliminary and all capacity estimates should be reviewed by a licensed structural engineer, as actual outcomes depend on site-specific inspections.
