Is anyone familiar with the publication "Simplified Field Method for Capacity Evaluation of Driven Piles" (Paikowsky 1994)particularly regarding the data plot comparisons of CAPWAP vs.load test results?

Dear Mike:
Please refer to the paper
"CAPWAP Correlation Studies" - Likins, G., Rausche, F., Thendean, G. and Svinkin, M., STRESSWAVE'96 Conference, Orlando, FL, 1996
published in the conference proceedings and available online at www.pile.com/education.

I am familiar with the paper you describe. The Simplified Method (or Energy Approach) is based on the relationship between transferred energy and pile top displacement collected during dynamic testing along with the observed pile set (inverse of blow count). The method is accurate for piles driven to blow counts greater than 4 blows per inch and at deeper penetrations.
This method along with CAPWAP were both compared to static load test results to failure based on a large data base developed from data obtained from UMASS Lowell, FHWA, GRL and GTR data bases.
Refer to: Paikowsky, S.G., Regan J.E., and McDonnell J.J., "A Simplified Field Method for Capacity Evaluation of Driven Piles", FHWA research report. No. RD - 94-042, 1994, 291pp (HNR publication).
