Abstract: Effective project scheduling is essential for the successful execution of any project. It serves as a fundamental tool to ensure that projects are completed within their designated timelines, and budget constraints, and with minimal disruptions. However, current requirements in the construction industry present a landscape of scheduling challenges. Various aspects, such as multiple calendars, constraints, lags, resource allocation, and even budget considerations, introduce complexity that can render schedules highly sensitive to changes. Even minor modifications can trigger cascading effects, significantly impacting project timelines, and making schedules difficult to interpret.

This paper closely examines the process of integrating contractual requirements into project schedules with the help of a case study on an infrastructure project to illustrate how this alignment introduces complex scheduling challenges, influencing the critical path, near-critical paths, and/or driving paths for special milestones on different stages of the project.

The goal is to develop a comprehensive understanding of how these complexities underscore the necessity for project schedulers and stakeholders to collaborate effectively, creating schedules that faithfully represent project complexity while fully harnessing the capabilities of the scheduling software.
