Determining timber pile length is critical when evaluating the potential effects of scour and for determining pile capacity. Unfortunately, records of timber pile lengths are typically nonexistent for older bridges. A nondestructive technique has been applied to determine the length of in situ timber piles. Field testing was conducted on 24 newer piling and 10 older piling ranging from 6.0 meters to 18.3 meters long at eight bridge sites in Colorado, Louisiana and Tennessee. The nondestructive technique provides length estimates within approximately 15% of the average bent pile length.
