How do you communicate a multidiscipline project schedule for a new light rail extension that spans a 4-year time period? Significant elements must include illustrating the geographic area of a new 5.8-mi track alignment; representing the major scope or work activities within each region; planned construction durations and contract completion dates for work associated with utility relocation; civil and track construction; electrical, mechanical, and communications installation; vehicle manufacturing; major structures construction; and systems testing and startup. Tri-County Metropolitan Transportation District of Oregon (TriMet) and their contractors utilize sophisticated scheduling software to efficiently manage large multidiscipline light rail design and construction projects. When projects are large and complex the critical path scheduling methods are vital for managing multiple interrelated projects, as well as being a crucial element in the accurate monitoring and reporting of the overall effort. However, as the project grows in size, scope, and complexity, so does the schedule. When the number of detailed activities in the schedule expands, with complicated logic and sequencing ties, it becomes hard to review at a glance and has the potential to lose some audiences. Consider the geographic schedule developed for the TriMet Interstate MAX light rail project. This schedule format is a graphical representation of the project detailing multifaceted activities planned along the alignment over the duration of the project. The geographic schedule has worked as a planning tool for various disciplines to plan their work, coordinate turnover to follow-on contractors, and serves as a communication tool to present general audiences with a view of the scope and overall timeline of the project.
