主材价格走势对公路工程造价的影响分析

Analysis of the Impact of Main Material Price on Project Cost

文中指出主材价格波动是导致工程造价增长的主要原因,并结合具体工程项目分析主材价格波动带来的影响。当工程设计方案不变时,通过调整材料单价来调整造价的幅度最大约为30%,在工程项目前期设计阶段应对工程实施阶段的主材价格进行预估。

The main material price fluctuation was the main reason leading to the project cost increase,and the effects of small fluctuations and large fluctuations for major materials combing with specific engineering projects were explained.When the engineering design plan is unchanged,the maximum adjustment of the cost of the material is about 30% by adjusting the unit price.In the early design stage of the project,the price of the main material should be estimated during the project implementation phase.
