The method for determining existing pile condition in timber pilings for bridges is to drill through the pile and determine the amount of rot that has occurred inside the pile. Typically, the existing pile condition is worse than the exterior condition would suggest, as the pile deteriorates from the inside out. As the drill penetrates through the pile the resistance is measured and the amount of rot, or loss of section, can be estimated. Once the pile condition is determined it becomes a simple calc. to determine the load capacity of the pile using the "unrotted" timber section as load carrying.
