In addition to analysis, design, and other pile testing and monitoring, PND Engineers, Inc. (PND) is pleased to announce the addition of the Pile Driving Analyzer (PDA) system with the Case Pile Wave Analysis Program (CAPWAP) to our list of non-destructive testing capabilities. The PDA technology is the most prevalent system for dynamic load testing and pile driving monitoring. The high-strain dynamic load tests, referred to as PDA tests, assess the capacity, integrity, and driving stresses during the installation of driven piles. Further monitoring of hammer energy and efficiency can be made during driving. All testing procedures follow American Society for Testing and Materials International D4945 Standard Test Method for High-Strain Dynamic Testing of Deep Foundations.
PND's trained engineers can perform this work on both test and production piles using the high-strain impact provided by either an impact hammer or a drop weight. Piles can be steel, concrete, or timber with sensors temporarily attached to the pile which allow for monitoring during driving and collecting data real time. The real-time collection of data allows for more efficient field direction during pile installation. PND has successfully used PDA and CAPWAP analysis in on- and offshore capacities, including a recent job in the remote Canadian Arctic.
Elizabeth Peratrovich First Tlingit Enshrined in Hall
On November 2, 2019, Elizabeth Peratrovich was inducted into the National Native American Hall of Fame at a ceremony at the Hard Rock Hotel and Casino in Tulsa, Oklahoma. Elizabeth, the mother of PND Engineers, Inc. co-founder Roy Peratrovich, Jr., was one of 12 inductees in the fledgling Hall of Fame's second class.
