Analysis of Factors Affecting Construction Cost of Line Engineering and Cost Control Strategy

Abstract

The construction of power transmission and transformation project is a basic construction related to the national economy. The factors affecting the construction cost are intricate. In this paper, the fishbone analysis method is used to identify the influencing factors, with a total of 17 influencing factors being identified. The clustering analysis method is used to divide 17 factors into 5 categories. Then, through correlation analysis, 7 key factors are screened out; Gray comprehensive correlation is used to measure the impact of various key factors on investment. Based on the analysis of the influencing factors of cost, the whole process control strategy of overhead line engineering cost is proposed from the investment estimation stage, design stage, construction stage and completion settlement stage.
