Abstract

his research is a modeling of cost estimation of prestressed bridge project in Public Works and HousingDepartmentof Bina Marga East Java ProvinceIndonesia. The purpose of this research is to get an accurate initial cost estimation taking into account the time series data of project cost budget and the inflation value that prevailed in the previous years. Data collection is taken from the contractor and the Public Works and Housing Department ofBinaMarga East JavaProvinceIndonesia from 2011-2016. Data analysis using Cost Significant Modelling (CSM) and multiple linear regression with the help of SPSS version 22 software. The results concluded that 97,90% of the work affecting the cost of the prestress bridge project consists of : pavement and asphalt work (X3), top material building (X7) and masonry work (X9). The equation model of cost estimation of prestige bridge structure construction with Cost Significant Model is in the form of regression equation, Y = 26,217,681.38+ 2,108 X3+ 1,513 X7 + 1,161 X9. The estimated model accuracy ranges from -10,20% to + 6,75%, with an average of + 8,48% accuracy. The estimation result of this study is better when compared with the estimation using long road parameters used by the Public Works and Housing Department of Bina MargaEast Java Province Indonesia whose accuracy ranges from -38,68%to + 38,05%, with an average accuracy of 14,47%. Keywords:estimate, cost model, bridge, prestress, CSM.
