The Pile Driving Analyzer® (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. The PDA eighth generation (PDA-8G) 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 pile driving hammer or a suitable drop weight PDA-8G evaluates: • Static Soil Resistance • Pile Structural Integrity • Dynamic Pile Stresses • Hammer Energy Transferred to Pile The PDA-8G is designed with the field engineer in mind. The 8G allows for up to 16 channels of data acquisition (wireless mode) with “smart” sensors knowing their calibrations and allowing any sensor to plug into any acquisition channel. Its screen, with a higher resolution LCD than previous generations of PDAs, displays measured signals and calculated results in real time, and allows more options to be viewed simultaneously High Strain Dynamic Load Testing The real-time PDA-8G results are complemented by analysis with the CAPWAP® signal matching software, for results that correlate very well with static load tests. High Strain Dynamic Load Tests may be performed on driven piles, drilled shafts, continuous flight auger piles, or cast-in-situ piles. The PDA-8G has features that make it easy to use for drilled shaft testing, such as the option of conducting the test with up to eight channels in wired mode and 16 channels in wireless mode. The PDA-8G can also perform the necessary measurements required by ASTM D7383.
