特高压输变电工程造价控制目标优化与管控

Optimization and Control of Cost of UHV Project

摘要: 合理进行特高压工程造价管控，有利于形成科学的造价管控体系，为待建特高压输变电工程造价管控提供指南，有利于合理确定工程造价管理管控水平，提高投资效益、经济效益和社会效益。提出了一种基于概率思想的特高压输变电工程造价管控策略，通过对造价期望值、标准差、置信度的分析，结合考虑工程建设阶段和不同主管部门的管控力度，构建特高压输变电造价控制区间。在此基础上，进一步考虑工程造价的偏差溯源分析技术，通过造价偏差分析，可合理确定需重点管控的子模块，为实际工程造价管控提供指导。

Abstract: Reasonable control of the cost of ultra-high voltage project is conducive to the formation of a scientific cost control framework for the construction of ultra-high voltage project, which can provide guidance for cost management and control and is beneficial to a reasonable determination of project cost management level and improve investment efficiency, economic and social benefits. A cost control strategy of UHV project based on probabilistic theory is proposed. By the analysis of cost expectation, standard deviation and confidence, the UHV project cost control interval is established, considering the construction stage and the control of different departments. On this basis, the deviation tracking technique of the UHV project cost is further analyzed, by which the sub-module to be controlled is determined and guides for the actual project provided.
