Conceptual Planning of Highway Construction Projects
Highway construction projects typically experience cost overruns and schedule delays, which could lead to perceptions of incompetence and erosion of support from the legislature and the public. One of the main causes behind cost overrun is prolonged construction duration. This paper will review and evaluate the methodologies currently adopted by state departments of transportation to estimate project duration and cost for both new construction and rehabilitation projects. This presents the first step in developing a self-learning comprehensive model to forecast project time and cost at completion, which is currently underway at University of Nevada Las Vegas. The proposed model will employ geographic information systems and artificial neural networks to estimate the construction costs of highway projects, for both new construction and rehabilitation/upgrade projects. The model will be self-learning, such that its estimates will improve over time, and with a wealth of projects completed.
