Understanding the Effect of Bid Quantities,Project Characteristics,and Project Locations on the Duration of Road Transportation Construction Projects during Early Stages

Abstract

Creating accurate estimates for the duration of road transportation projects is a challenging task that estimators and engineers have to face daily, and a lack of understanding of what drives such durations is a big contributor to this challenge. This paper expands on the efforts created by previous research efforts, not only by adding more variables to the model, but also by combining all project sizes and types into a single model. These additions increased the amount of explained variability, and the range of projects that can be studied with one model. This paper aims to determine which of the variables analyzed best predict project durations.
