Faced with the problem of determining how accurate, or how definitive, were the model elements to which they wished to assign costs, they developed the concept they called "Level of Detail". LOD 100 meant not very definitive (an area or volume rate is accurate enough) LOD 200 assume the number of items in the model is correct, but use an estimate for each, LOD 300 items are identified and actual cost can be used, LOD 400 is a m...
