What is iCAP®?

iCAP® is a signal matching program. It works in parallel with Pile Driving Analyzer® models PDA-8G or PAX , the PDA-S or PDA-L data collection programs, and/or with the PDA-W program. Furthermore, iCAP is completely automatic, which outputs an unique answer. As a result, no user intervention is needed or permitted. Under ideal circumstances, iCAP allows for immediate capacity assessments during data collection and review for driven piles of known geometry. For more information, click here.

The PDA-8G programs, used onsite or remotely with SiteLink® technology, sends data to iCAP. Following, iCAP performs an automatic signal match procedure, similar to that available with the CAPWAP program. The only difference is that iCAP employs faster algorithms. Depending on the blow rate of the hammer, and the iCAP options selected, the results may be a few blows behind the current installation data. The PDA-8G displays the last available numerical and graphic signal matching results from iCAP, as well as the currently collected data. iCAP displays the following results:

Numeric:

•RU – total iCAP capacity

•SF – skin friction

•EB – end bearing

•MQ – match quality number – allows the user to evaluate the validity of the iCAP result

•JC – Case Method damping factor – allows the user to fine tune the CASE method results

•CSC – Maximum compression stress

•TSC – Maximum tension stress

Graphic:

•Load-displacement curve

•Force in pile versus depth

•Wave-up measured versus Wave-up calculated
