Construction sand and gravel one of the most accessible natural resources and a major basic raw material is used mostly by the construction industry Despite the low unit value of its basic products the construction sand and gravel industry is a major contributor to and an indicator of the economic well being of the NationJan 19 32 Units of Production Depreciation Example Pensive Corporation’s gravel pit operation Pensive Dirt builds a conveyor system to extract gravel from a gravel pit at a cost of $400 000 Pensive expects to use the conveyor to extract 1 000 000 tons of gravel which results in a depreciation rate of $040 per ton 1 000 000 tons / $400 000 cost
