CPM Scheduling: Activities, Relationships, Float, and the Critical Path That Defines Project Duration
Critical path method (CPM) scheduling is the foundation of commercial construction project management. Activities, predecessor/successor relationships, durations, float calculations, and critical path identification produce the schedule that drives coordination and claim analysis. Understanding CPM basics is essential for anyone working on scheduled construction projects. The mechanics are specific and unforgiving — correct CPM application produces useful schedules, incorrect application produces plans that mislead.
