建材价格波动对地铁项目工程造价影响的观察模型

An Observation Model for the Influence of the Price Fluctuation of Building Materials on the Project Cost of Metro Projects

地铁项目建设规模大、建设周期长,建筑材料用量多。单条地铁线路,建材价格波动可能引起巨大的工程造价变化。量化分析主要建材的价格波动对地铁项目工程费用、总工程造价产生的影响,进而建立一套系统的建材价格波动对项目工程费用、工程造价影响的观察模型,为从业人员快速预估建材价格波动对项目工程造价影响程度和投资额提供参考。

The subway project has a large construction scale,a long construction period and a large amount of building materials.The price fluctuation of building materials for a single metro line may cause severe project cost changes.Quantitative analysis of the impact of the main price fluctuation of building materials on the direct poject cost and the total project cost of the metro project,and then establish a systematic observation model of the impact of the price fluctuation of building materials on the direct project cost and the total project cost,so as to provide a reference for the practitioners to quickly estimate the impact of the price fluctuation of building materials on the project cost and the amount of investment.
