在土木建筑工程中,构成实体建筑物的主要材料用量很大,由于国家市场价格放开和各类建材与机械配件等较大价格的浮动,对于工期较长的土木建筑工程,承包商按照投标时的报价,在施工过程中,施工费用会有较大辐度的增减。针对这一状况,在国际上通用的土木建筑工程合同中,有相应的条款予以规定。依据该规定,对材料价差的不同调整方法加以粗浅分析与探讨。 In civil engineering, the amount of the main materials constituting physical buildings is very large. Due to the liberalization of national market prices and the large price fluctuations of various kinds of building materials and mechanical parts, for civil works with a longer construction period, When the quotation, in the construction process, construction costs will have a greater degree of increase or decrease. In response to this situation, in the international common civil engineering contract, there are corresponding provisions to be provided. According to this regulation, the different methods of adjusting the material price difference are analyzed and discussed.
