Abstract

The significant difference between the owner estimate (OE) and the winning bid price (COGS) is expected to cause non-optimal use of the budget for transportation infrastructure development which indirectly causes hampering the acceleration of regional economic growth in a region. This study aims to analyze the differences that occur using mathematical models and parametric statistical analysis. The analysis was carried out on all transportation infrastructure projects in the East Java region from 2017 to 2021, namely 464 projects. The results of the analysis showed that a simple linear regression model was chosen to be the model that best describes the relationship between the owner estimate (OE) and the winning bid price (COGS). Parametric statistical analysis shows that the level of difference between the two variables is still within reasonable limits.
