钢结构箱型柱施工费用预估模式的研究

Forecast Models for Estimating Construction Cost of Box Steel Column

过去钢构制作进度预估及成本估价皆为经验法,导致施工进程须依个案加以规划。本研究利用施工现场生产力数据与影响因子,希望能建置一套施工费用预估模式。研究结果发现箱型柱制作作业具有高度重复及线性循环等特性。因此,本研究以线性回归方法建置钢结构箱型柱作业生产力预估模型。由于建置施工费用预估模式能够规划有效进程、方便管控预算成本及控制施工成本,因此可供钢结构厂预估最佳工期与成本,以减少预算损失。

In the past, steel production cost and progress prediction are empirical method, leading to the construction process in accordance with the case of planning. The construction site and the influence factor of productivity data are used in this study, hoping to establish a prediction model of construction cost. The research results show that the production operation of box column has the characteristics of high repetition and linear cycle. Therefore, based on the linear regression method, this study builds the steel box column work productivity prediction model. Because the implementation of construction cost estimate model can effectively plan the process, conveniently control the budget and the construction cost, it can be used to estimate optimum duration and cost for steel structure factory in order to reduce the loss budget.
