基于全寿命周期的建设项目成本风险管理探讨

Research on Risk Management of Construction Project Cost Based on the Theory of the Whole Life Cycle

基于全寿命周期的建设项目成本管理,在立项、设计、施工、运营、报废回收5个阶段都存在不同类别的不确定性,这种不确定性会增加项目成本管理中的风险。根据建设项目全寿命周期内各阶段的特点,对建设项目在不同阶段可能发生的成本风险因素进行识别与评价,根据评价结果提出各阶段可采取的应对风险的控制措施,可减少或避免可能发生的成本风险,达到实行项目成本风险管理的目的。

The construction project cost contians a variety of different types of uncertainties in the whole life cycle five phases including decision - making, design, construction, operation, scrap recycling. Uncertainties will increase the risk of project cost management. Considering the characteristics of the construction pro- ject, identify the risk factors of construction project cost by stages, explore appropriate cost risk estima- tion methods evaluation method, then propose control measures by phases based on the recognition results which offer a reference to project cost management personnel.
