一、土方量对工程造价的影响黑龙江省把市政工程划分为四种类型,其中:一类为焊口有探伤要求的燃气,热力管道工程;四类为焊口无探伤要求的燃气,热力管道工程以及给水、排水工程;其计费基础是人工费。市政三类工程其综合费率是人工费×112.3%,而在大中城市施工中,由于地下管线较多,障碍物多,因机械井挖沟槽困难大,多采用人工开挖沟槽,因此,土方量的多少,将直接影响工程造价,且幅度较大,所以合理地、精确地计算土方量对于控制
First, the amount of earthwork on the impact of project cost Heilongjiang Province, municipal engineering is divided into four types, of which: a class of welding flaw detection requirements of the gas, thermal pipeline project; four for the weld flaw detection gas, heat pipe Engineering and water supply and drainage works; the basis of billing is labor costs. In the construction of large and medium-sized cities, due to the large number of underground pipelines and the large number of obstacles, it is difficult to excavate trenches in mechanical wells and more artificial trenches are to be used for excavation. Therefore, the amount of earthwork, will directly affect the project cost, and a large range, so a reasonable and accurate calculation of earthwork for control
