This project provides a comprehensive analysis of supply chain and procurement management within the context of the East Side Access railway project in New York City. It evaluates activities suitable for contracting out, creates a request for project work to be contracted out, and determines criteria for selecting sellers. The analysis justifies the chosen contract type, fixed price economic price adjustment, based on the project's long duration and potential for inflation, while rejecting time material and cost-plus contracts due to uncertainties in income and cost rates. The project highlights the importance of innovative technologies and strategic planning in successful railway construction and emphasizes the significance of the East Side Access project in relieving congestion and improving transportation for commuters.
