What Specific Data Points must a Special Inspector Record During Helical Installation?

During the continuous special inspection of a helical pile installation, our team and the assigned special inspector must record specific field data to verify that the as-built foundation aligns with the engineered design and IBC 2026 requirements.

We record the following specific data points during installation:

Depth of penetration: The total depth reached by the pile and its final tip elevation.
Torque readings: Recorded at every foot of advancement to gauge soil resistance and establish the torque-to-capacity correlation.
Centerline coordinates: The precise as-built position of each pile.
Plumbness: Monitoring the vertical alignment of the pier shaft against specified tolerances.
Helical plate embedment: The specific depth of the plates relative to the targeted bearing stratum.
Splices and extensions: Documentation of any added sections and the specific torque applied when they were integrated.

This real-time data collection allows for immediate adjustments if a pile deviates from alignment or if torque trends vary from expectations. These records are compiled into a final as-built package that serves as the permanent record for your property.

Disclaimer: All information is for general purposes; actual outcomes depend on site conditions. Consult a licensed structural engineer for definitive design recommendations.
