Name	Type	Description
TypeDesignator	P_SINGLEVALUE / IfcLabel	Type Designator Type designator for the precast concrete element. The content depends on local standards. For instance in Finland it usually a one-letter acronym, e.g. P=Column, K=reinforced concrete beam,etc. 特定子の記述 プレキャストコンクリート要素の特定子（部位）を記述する。内容はローカルな（各国の）標準（規格）に依存する。例えばフィンランドでは、柱はP、梁はKのように通常、頭文字1文字で表す。
CornerChamfer	P_SINGLEVALUE / IfcPositiveLengthMeasure	Corner Chamfer The chamfer in the corners of the precast element. The chamfer is presumed to be equal in both directions. 面取り プレキャストコンクリート要素の面取り。面取りは両方向で等しいものとする。
ManufacturingToleranceClass	P_SINGLEVALUE / IfcLabel	Manufacturing Tolerance Class Classification designation of the manufacturing tolerances according to local standards. メーカーの認可分類 ローカルな標準によるメーカーの認可分類。
FormStrippingStrength	P_SINGLEVALUE / IfcPressureMeasure	Form Stripping Strength The minimum required compressive strength of the concrete at form stripping time. 脱型強度 脱型時におけるコンクリートの最小必要圧縮強度。
LiftingStrength	P_SINGLEVALUE / IfcPressureMeasure	Lifting Strength The minimum required compressive strength of the concrete when the concrete element is lifted. 吊り上げ強度 コンクリート要素が吊り上げられる時のコンクリートの最小必要圧縮強度。
ReleaseStrength	P_SINGLEVALUE / IfcPressureMeasure	Release Strength The minimum required compressive strength of the concrete when the tendon stress is released. This property applies to prestressed concrete elements only. リリース強度 緊張力が解放される時のコンクリートの最小必要圧縮強度。この属性はプレストレストコンクリート要素のみに適用される。
MinimumAllowableSupportLength	P_SINGLEVALUE / IfcPositiveLengthMeasure	Minimum Allowable Support Length The minimum allowable support length. 最小許容支持長さ 最小許容支持長さ。
InitialTension	P_SINGLEVALUE / IfcPressureMeasure	Initial Tension The initial stress of the tendon. This property applies to prestressed concrete elements only. 初引張力 緊張材の初期応力。この属性はプレストレストコンクリート要素のみに適用される。
TendonRelaxation	P_SINGLEVALUE / IfcPositiveRatioMeasure	Tendon Relaxation The maximum allowable relaxation of the tendon (usually expressed as %/1000 h).This property applies to prestressed concrete elements only. 緊張材のリラクセーション 緊張材の最大許容リラクセーション（応力弛緩、－係数）。通常、1000時間あたりの割合（%)。この属性はプレストレストコンクリート要素のみに適用される。
TransportationStrength	P_SINGLEVALUE / IfcPressureMeasure	Transportation Strength The minimum required compressive strength of the concrete required for transportation. 輸送強度 輸送に必要なコンクリートの最小必要圧縮強度。
SupportDuringTransportDescription	P_SINGLEVALUE / IfcText	Support During Transport Description Textual description of how the concrete element is supported during transportation. 輸送中の支持に関する記述 プレキャストコンクリート要素が輸送中における支持方法について書かれたテキスト文書。
SupportDuringTransportDocReference	P_REFERENCEVALUE / IfcExternalReference	Support During Transport Doc Reference Reference to an external document defining how the concrete element is supported during transportation. 輸送中の支持に関する参考文献 プレキャストコンクリート要素が輸送中における支持方法について書かれた外部ドキュメントの参照。
HollowCorePlugging	P_SINGLEVALUE / IfcLabel	Hollow Core Plugging A descriptive label for how the hollow core ends are treated: they may be left open, closed with a plug, or sealed with cast concrete. Values would be, for example: 'Unplugged', 'Plugged', 'SealedWithConcrete'. This property applies to hollow core slabs only. くぼみの充填 （定着部の？）くぼみをどのように扱うのかについて書かれたラベル：開けたままにするか、プラグで塞ぐ、または後詰めコンクリートで塞ぐ。例えば、「塞がない」、「塞ぐ」、「コンクリートで塞ぐ」と書かれるだろう。この属性はスラブに開けられたくぼみにも適用される。
CamberAtMidspan	P_SINGLEVALUE / IfcRatioMeasure	Camber At Midspan The camber deflection, measured from the midpoint of a cambered face of a piece to the midpoint of the chord joining the ends of the same face, as shown in the figure below, divided by the original (nominal) straight length of the face of the piece.
BatterAtStart	P_SINGLEVALUE / IfcPlaneAngleMeasure	Batter At Start The angle, in radians, by which the formwork at the starting face of a piece is to be rotated from the vertical in order to compensate for the rotation of the face that will occur once the piece is stripped from its form, inducing camber due to eccentric prestressing.
BatterAtEnd	P_SINGLEVALUE / IfcPlaneAngleMeasure	Batter At End The angle, in radians, by which the formwork at the ending face of a piece is to be rotated from the vertical in order to compensate for the rotation of the face that will occur once the piece is stripped from its form, inducing camber due to eccentric prestressing.
Twisting	P_SINGLEVALUE / IfcPlaneAngleMeasure	Twisting The angle, in radians, through which the end face of a precast piece is rotated with respect to its starting face, along its longitudinal axis, as a result of non-aligned supports. This measure is also termed the ‘warping’ angle.
Shortening	P_SINGLEVALUE / IfcRatioMeasure	Shortening The ratio of the distance by which a precast piece is shortened after release from its form (due to compression induced by prestressing) to its original (nominal) length.
PieceMark	P_SINGLEVALUE / IfcLabel	Piece Mark Defines a unique piece for production purposes. All pieces with the same piece mark value are identical and interchangeable. The piece mark may be composed of sub-parts that have specific locally defined meaning (e.g. B-1A may denote a beam, of generic type ‘1’ and specific shape ‘A’).
DesignLocationNumber	P_SINGLEVALUE / IfcLabel	Design Location Number Defines a unique location within a structure, the ‘slot’ for which the piece was designed.
