This CPM schedule on AHPP pg 632 got me very confused. I tried to highlight the critical path activities, but not sure I got it correct. Plus, shouldn't a critical path schedule be the one with lines and bubbles? I always thought this one was a Gantt chart.

  I think you have to add " Owner move in for high school " and " project closeout " as Commissioning will be Float. The lines and bubbles are simplified graphic presentation for CPM, the above is created by software usually for construction stage.

  There are a few different graphic formats of critical path scheduling, and it will be worth your time to become familiar with the most common formats for the exam. Broadly speaking, the critical path method (CPM) is simply a tool that provides a means of determining which jobs or activities, of the many that comprise a project, are “critical” in their effect on total project time, and how best to schedule all jobs in the project in order to meet a target date at minimum cost (source). A gantt chart used in conjunction with critical path analysis is only one example. Network diagrams are the other most common example.

  And as Haytham alluded to, float is an important concept to understand as it relates to CPM.
