建设项目成本估算BAF模型的构建及应用

Building and Application of Construction Project Cost Estimation Model Based on BAF

结合体现项目进度的β曲线,以建设项目实施进程中的成本数据和工程造价经验数据为依托,从内部估算和外部估算两个角度入手,构建了一个建设项目成本估算BAF模型,对项目执行过程中的估算成本进行动态预测,以提高项目成本预测的精度。

Combining with the β line which can reflect the project schedule,the paper builds a BAF model on construction project cost estimate based on the cost data in project implement and empirical cost data,dynamically predicts the estimate cost in project implement progress from internal estimates and external estimates,to improve the cost prediction accuracy.
