Unknown Pile Length Determination in Orilla, ON

The Problem

FPrimeC was engaged by Roehampton Communications Ltd. to perform low strain integrity testing on existing piles of a lattice tower in Orillia, ON. The client was interested in determining the unknown length of the piles.  The main objective of this project is to conduct Pile Integrity Testing to estimate the unknown length of the piles.

Unknown Pile Length – Pile Integrity Test

FPrimeC Solutions performed the pile integrity test over the existing Caisson piles of the lattice tower. The entire area was covered with snow and certain field preparations were conducted. Snow was removed from the piles’ surface; ice was removed at four (4) locations over each pile for the test; the test locations were dried before placing the sensor.

Low strain pile integrity test is a common non-destructive test (NDT) procedure for quality control and quality assurance (QC/QA) in deep foundation construction. The test can be used to identify physical defects (voids or discontinuity, referred to as pile integrity) in piles, or determine unknown length of existing deep foundations.

Low strain impact integrity testing provides acceleration or velocity and force (optional) data on slender structural elements (ASTM D5882). Sonic Echo (SE) method was employed for the integrity test on deep foundation and piles. The test results can be used for evaluation of the pile cross-sectional area and length, the pile integrity and continuity, as well as consistency of the pile material.
