Abstract

This paper presents the results of research on anticipation and solutions to subcontractor cost overruns on open system toll road projects in Jadebotabek. The purpose of this study is to determine the anticipation and solutions to handling subcontractor cost overruns. This research was conducted by conducting a survey of 76 respondents consisting of Managers, Consultants and Contractors involved in toll road construction in Jabodetabek which is a coastal area. The survey results were tested for validity, reliability and mean to determine the dominant factors causing cost overrun, then developed anticipation and solutions for handling subcontractor cost overrun by a team of experts. The results showed that there were 22 valid cost overrun causal factors with a coefficient value of 0.245 - 0.670 and 23 reliable cost overrun causal factors with a Cronbach's alpha value above 0.700. The results of this study also show that the anticipation and solution to handling subcontractor cost overruns in the coastal toll road project is a preventive measure to reduce and eliminate the occurrence of cost overruns at the planning stage and at the implementation stage.
