Abstract： In Indonesia， reliable cost estimating methods for the preliminary phase of construction project are not developed adequately； nevertheless， the one for bridge construction. However， the need to have a conceptual estimating method for bridges and other infrastructure is increasing since the Indonesian government is planning to speed up the economic development by providing infrastructures as the first important step. This research tried to develop two models of cost indices that can be used to estimate the cost of bridge construction in the preliminary phase for budgeting purposes. The first cost index model is developed based on cost per square meter of the bridge. Moreover， in the second model， the research tried to find the more accurate method in estimating the cost of bridge construction by breaking down further the bridge cost structure into bridge physical components： i.e.， sub structure， upper structure， and approaches. The analysis was conducted to validate the model by comparing the estimates made by the models to the ones calculated by the use of the consumer price index and the construction cost index. The developed models in this research proposed improvement in accuracy of estimation for bridge construction cost.

摘要：印度尼西亚尚未充分开发出适用于施工项目初期的可靠成本估算方法，但已有适用于桥梁施工的成本估算方法。但由于印度尼西亚政府正计划加速发展经济，而这所要求的首要步骤就是提供基础设施。因此开发出适用于桥梁和其他基础设施的概念评估方法的需求就变得愈发紧迫。本文试图构建两个成本指数模型，可适用于桥梁施工初期阶段成本估算，便于预算编制。其中第一个成本指数模型的构件基于每平方米桥梁的成本构建；而在第二个模型中，本研究试图将桥梁成本结构进一步细分为如下部结构、上部结构和引桥等三个桥梁实体部分，从而找到更精确的桥梁施工成本评估方法。本文旨在通过比较模型所得估算结果与消费价格指数和工程造价指数计算所得结果，进行模型验证；本文中所构建的模型方案可提高桥梁施工成本的估算精度。
