Properties specific to SteelPipePile:

Property or Attribute Name (Type)	Definition	Cardinality
wallThickness (eml:LengthMeasureExt)	The thickness of the pipe wall, measured perpendicular to the pipe axis.	0..1
openEnded (boolean)	Indicates whether the bottom end of the pipe is open (true) or closed (false).	1
concreteFilled (boolean)	Indicates whether the pipe is filled with concrete after installation (true) or not (false).	0..1
soilPlugDepth (eml:LengthMeasureExt)	The depth to which soil has plugged the pipe during driving, measured from the top of the pipe.	0..1
soilPlugElevation (eml:LengthMeasureExt)	The elevation of the soil plug within the pipe, measured relative to a reference datum.	0..1
splices (SpliceArrayPropertyType)	An array that describes the location and type of any splices that join multiple pipe segments together to create a longer pile.	0..1

Key Points:

• Cardinality:
  • The "0..1" cardinality means the property is optional for a given pipe pile.
  • The "1" cardinality for openEnded means it is a required property and must be provided for each pipe pile.
• Data Types: The linked data types provide very specific information about how these properties should be formatted and measured.
