Abstract

Evaluating existing pile foundations is becoming more critical as the nation's infrastructure ages. Limited or non existent pile installation records are common making it very difficult to assess an existing foundation's capacity, evaluate pile integrity, and determine pile penetration in scour conditions. Low and high strain nondestructive testing are cost effective tools to determine pile length, integrity, and bearing capacity of existing pile foundations. This paper provides a general overview of low and high strain testing as applied to testing existing piles incorporated in structures.
