PileDrivingRecord Measurement Properties

The following are observed properties that may be recorded on as part of a pile driving record. The code value is used as part of the propertyClass property within a DriveRecordProperty object.

For comments/feedback on the elements below or to propose properties that are missing, create a post at the Deep Foundations: Schema Discussion.

ID	Name	Description	DataType	QuantityClass
blow_count	Blow Count	The number of strikes of the hammer against the pile for a distance given by pen_increment	integer	dimensionless
stroke	Stroke length	The height of hammer fall onto the pile	double	length
energy	Energy	The energy delivered to the pile	double	energy
bearing	Bearing	The bearing of the pile at a given tip depth, as determined from a Wave Equation Analysis or Dynamic Formula of the driving system.	double	force
tip_elevation	Tip elevation	The elevation of the pile tip, where value and unit of measure are defined by the coordinate reference system of the pile's centerline origin (eg cutoff elevation)	double	length
remark	Remark	A note specifically associated with the domain value (pile tip position) and/or other measurements at this location	string	dimensionless
pen_increment	Penetration Increment	The distance that the pile tip travels for a given number of hammer blows	double	length
pen_per_blow	Penetration per blow	The distance traveled per blow of the hammer. This value is typically computed from the blow_count and pen_increment values	double	length
time	Time	Time recorded	time	time
pressure	Pressure	Pressure at hammer for double acting hammer or downthrust pressure when vibrating	double	pressure
