现行定额中,材料费约占70%左右,材料价格直接影响投资规模,因此收集,整理和向社会发布工程建设材料信息是当前工程造价管理工作的一个重要组成部分。材料价格具有变化幅度大,频率高,规律性差的特点。针对这些特点,有关主管部门相应扩大了材料价格开口范围,增加相关费用项目,建立建材市场价格信息网络等,定期向社会提供村料价格信息,有效地将材料价格的动态变化发布出来,材料价格信息的普遍推行,使它在工程造价中的作用显得更为重要。首先,在编制工程建设概、预算时,按现行规定必须以实际材料市场价格为依据。并应考虑建设期材料价的动态上涨因素,在项目实施阶段,应当根据
In the current quota, the material fee accounts for about 70%, and the material price directly affects the scale of the investment. Therefore, collecting, sorting, and releasing information on the project construction materials to the society is an important part of the current project cost management work. The material price has the characteristics of large variation, high frequency, and poor regularity. In response to these characteristics, relevant competent authorities have correspondingly expanded the range of material price opening, increased related cost items, established a price information network for building materials market, etc., and regularly provided villages with material pricing information to effectively publish the dynamic changes in material prices. The universal implementation of information makes its role in project cost more important. First of all, in the preparation of project construction plans and budgets, the current regulations must be based on actual market prices. The dynamic rise in material prices during the construction period should also be taken into consideration. At the project implementation stage, it should be based on
