Cost Overrun Factor of Toll Road Project Construction

Abstract

Abstract Results in more than 45 studies of infrastructure projects in 20 countries that ran overestimate. For rail projects, they predict average cost increases of 45%, for fixed-line projects (tunnels and bridges), of 34%, and for highway projects, of 30%. Indonesia is one of the 20 nations on 5 continents where cost overruns are a common occurrence. Cost overruns are one of the problems faced by most construction projects in Indonesia. Unexpected budget cost overruns can create many problems in the project. Therefore, every stakeholder in the project needs to have a good understanding of factors that cause cost overruns to avoid or minimize it risks in the project. The purpose of this study is to identify the factors that cause cost overrun on a project and analyze the factors that are most influential on the occurrence of cost overrun on construction projects. This study used a systematic literature review to collect data from previous studies. This study resulted in 6 management elements, consisting of 85 variables identified in this study. 6 management elements factors, including material factors, labor factors, equipment factors, subcontractor factors, financial factors, and external factors. This is a fairly broad category that includes projects. The most cause factor of cost overrun land acquisition problems
