PDCA Value Driven Webinar Series: High Strain Dynamic Load Testing (PDA tests) with GRLWEAP

When: 5/12/2022 2:00 PM - 3:00 PM

A collaboration between the PDCA Education Committee and the PDCA Associate Member Council Committee. Each webinar will be presented in case study or educational format to a target audience of contractors, engineers, estimators, etc.

The PDCA 2022 Value Driven Webinar Series will focus on driven pile case studies, cost saving analysis, actual project conversion methods, job site safety, soil set up, legalities to consider, and much more to support those in the driven pile industry.

High Strain Dynamic Load Testing (PDA tests) with GRLWEAP:
Pile Dynamics, Inc's. Pile Driving Analyzer® (PDA) is a reliable and cost effective QA product that can accommodate a wide variety of subsurface conditions, as well as eliminate the guesswork in foundation design.  High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day. Pile Driving Analyzer systems also evaluate shaft integrity, driving stresses, and hammer energy when monitoring installation. PDA tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer. Re-strike PDA tests are often recommended; if the driving hammer is no longer on location, a drop weight may be used to impact the pile. The PDA takes data obtained by accelerometers and strain transducers easily attached to the pile and calculates foundation capacity. Ryan Allin, P.E., will review the latest software release for the PDA, GRLWEAP14, along with best practices in pile driving testing and analysis.
