Schedule Development and Critical Path Method
Schedule Development in a construction design project involves outlining all project tasks, their durations, dependencies, and sequencing to ensure timely completion. The Critical Path Method (CPM) is a key scheduling technique used to identify the longest sequence of dependent activities, determining the minimum project duration. By pinpointing critical tasks with no scheduling flexibility, CPM helps project managers allocate resources efficiently and anticipate potential delays, ensuring effective project control and timely delivery.

❓ Frequently Asked Questions
What is the Critical Path Method (CPM)?
CPM is a project scheduling technique that links activities with dependencies, estimates durations, and identifies the longest path of activities—the critical path—that determines the minimum project duration. It also shows which activities have float.
How do you determine the critical path with CPM?
Create a network of activities, perform a forward pass to calculate earliest start/finish times, a backward pass for latest start/finish times, and identify activities with zero total float. The path of these activities is the critical path.
What is Schedule Development?
Schedule Development is the process of creating the project schedule by defining activities, sequencing them, estimating durations and resources, and integrating them into a schedule model to produce a baseline timeline.
What is float (slack) and why does it matter?
Float (slack) is the amount of time an activity can be delayed without delaying the project finish date (total float) or without delaying a successor (free float). Critical activities have zero total float.
