在工程预算和竣工结算中,主材(装置性材料)施工用量是按图纸的设计用量和规定的损耗率计算的。然而,在实际操作中,大多数工程因主材损耗计算公式有误而少算。为此,根据损耗率的涵义,推导了主材(装置性材料)施工用量的计算式以及因不正确算式而引起的量差以及其调整系数的算式,使主材(装置性材料)施工用量得到正确的计算。
In the project budget and completion settlement, the construction materials for the main materials (installation materials) are calculated based on the design consumption of the drawings and the specified wear rate. However, in actual operation, most of the projects are underestimated due to errors in the calculation formula of the main material loss. For this reason, according to the meaning of the loss rate, the calculation formula of the construction amount of the main material (device material) and the amount difference caused by the incorrect calculation formula and the formula of the adjustment coefficient thereof are deduced, so that the construction material amount of the main material (device material) is deducted. Get the correct calculation.
