特殊专项投资计算是水电工程建设期内加强资金控制与管理的重要环节,也是反映水电工程实际施工效率和实际成本结构的重要途经,还是解决水电工程的建设各方有关利益的重要手段。特殊专项投资计算包括的步骤主要有现场实测资料记录、现场实测资料整理、设计概算指标资料分解、相关资料对比、相关资料分析。其中相关资料对比可观察人工工时消耗量和主要施工机械台时消耗量指标的增加幅度,相关资料分析是在资料对比结果的基础上,从中梳理出不同影响因素单独存在或共同存在时,有关指标变化幅度的相关参数。
The special special investment calculation is an important part of strengthening capital control and management during the construction period of hydropower projects. It is also an important way to reflect the actual construction efficiency and actual cost structure of hydropower projects and also an important measure to solve the relevant interests of all parties involved in the hydropower project construction. The calculation of special special investment includes the following steps: recording the measured data in the field, arranging the measured data in the field, analyzing the data of design estimates, comparing the related data and analyzing the related data. Relevant data comparison between the observed consumption of man-hours and main construction machinery time consumption indicators of the increase rate, the relevant data analysis is based on the results of the comparison of data, from which the different factors exist separately or coexist, the relevant indicators The relevant parameters of the magnitude of change.
