LOA - Level Of Accuracy

LOA - Level Of Accuracy

LOA stands for Level of Accuracy. LOA is structured in five increments of ten beginning with LOA10 and extending thru LOA50. The five defined Levels of Accuracy are – LOA10, LOA20, LOA30, LOA40 and LOA50.

This specification prescribes five levels of accuracy for building documentation. Each of the five levels can be applied within the same project as the Level of Accuracy may be applied to the elements of the building documentation project and not necessarily to the project in totality.
