Here is a typical construction schedule shown in the Gantt chart format.  On this schedule several "outline levels" are used.  Summary bars are shown above the lower level bars, as a summary.

All Schedules on this web site were created using Milestones software. This includes Milestones Professional, which is a powerful, fast, and easy to use project scheduler, and Milestones Simplicity, a basic program for creating Gantt charts. These programs can both be used to present schedules. They are both great examples of project planning software.
