This paper assessed the impact of project delivery methods used by railroad organizations to perform highway-rail intersection projects with similar scope in New York State.
The improvement of infrastructure by public agency is to ensure satisfaction of the general public using such infrastructure with available funds. This study assessed the existing project delivery methods used to perform projects at public highway-rail intersections (HRI) in New York State.
Project delivery method is a process that defines the relationship between parties involved in a specific project. Any of the methods could affect a project budget, schedule, quality and the involvement of the project owner.
This study investigated the impact of project delivery methods used by different type/class of railroad organizations, which include passenger and freight railroad organizations on HRI projects within a 10 year period in New York State. Data for 256 projects with similar scope were sourced from the New York State Department of Transportation (NYSDOT).
The hypotheses were tested with non-parametric (Mann-Whitney and Kruskal Wallis) test using SPSS Statistical package version 20. Findings indicated statistically significant differences in total costs for project delivery methods used. Similarly, there were statistically significant differences in total costs of projects based on types/class of railroad organizations that performed the projects.
It was recommended that NYSDOT partner with railroad organizations toward share cost agreements, and monitor projects while in progress.
