湖南地区主电网工程可研造价控制线研究

Research on Cost Limit of Main Grid Feasibility Study in Hunan

投资估算的精度对精准投资和控制工程寿命周期造价具有重要作用,造价控制线是合理控制造价水平的重要手段。为了提高可研投资估算的精度,应用因果分析法和数据挖掘技术对已建工程进行分析,研究影响工程造价的关键因素,选出相似程度较高的典型工程,确定合理的可研造价控制线,提高可研估算编制和评审的质量,为电力企业投资决策和电网技经管理提供参考。

Cost estimate of feasibility study has deep influence on accurate investment and life cycle construction cost.Cost limit line is a useful method to control construction cost.In order to improve investment accuracy,this paper uses causal analysis and data mining method,researches the key factors of engineering cost,chooses the typical project of high similarity,determines the reasonable feasible cost control line,enhances the quality of feasible cost estimate preparation and review,which provides reference to grid investment decision and technical economy management.
