Pile Driving Analyzer® (PDA)

The Pile Driving Analyzer® (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. 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. If you plan to use your PDA to test non-driven piles make sure to read about that application as well. The PDA Model 8G (PDA-8G) is the culmination of a complete redesign effort that incorporates the latest technological innovations and truly embodies Pile Dynamics’s commitment to quality. The PDA-8G looks sophisticated, as so is the software that powers it. Thin, light and ergonomic, it features touchscreen gesture controls like swiping and pinch-to-zoom. The PDA-8G offers up to 16 universal channels of data acquisition, all capable of reading data from Smart Sensors in traditional (cabled) or wireless mode. This functionality allows for extreme pile testing flexibility. Improved data transfer makes it easier to test hydraulic hammers with high blow rates. 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. In addition, it calculates multiple important quantities by the Case Method and iCAP®. iCAP computes capacity in real time after every blow by signal matching (similar to CAPWAP®). This calculation is often more accurate than Case Method capacity and better evaluates stresses in the pile. With the PDA, the engineer has the option of being in the field for the pile driving test or of using SiteLink® Technology. SiteLink technology transmits PDA test data via Internet to an engineer located elsewhere who follows the test in real time. Test data displays and results are identical in both modes. The PDA is furnished with the PDA Software Suite, CAPWAP and GRLWEAP. CAPWAP analysis of PDA data is essential for a Dynamic Load Test. It provides the soil resistance distribution along the foundation and simulates a static load test. Extensive correlations between CAPWAP simulated and actual static load tests have proven the reliability of this method of determining pile capacity. PDA-DLT Software Add-On for Bored Piles and Drilled Shafts The PDA has an add-on software capability which is designed specifically for quality assurance testing of drilled shafts and bored piles. The PDA’s Dynamic Load Testing (DLT) software add-on allows for multiple configurations of force measurement. The software acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D4945) may be performed. The tests require the impact of a suitable drop weight. Learn more. The PDA conforms to ASTM D4945 and many other codes and specifications. The PDA Software Suite, consisting of PDA-S with iCAP, PDIPLOT2 and PDI-Curves, outputs reports that satisfy ASTM 4945 requirements. An SPT Software add-on to the PDA-S enables the PDA to determine the energy transferred to SPT rods (read about this application).
