What Is a CPM Schedule in Construction?

March 19, 2024

Construction projects involve countless activities, each of which has a direct impact on the project’s timeline. This is why it’s essential to have accurate and up-to-date project schedules. While there are many ways to create and display a project’s schedule, one of the most important methods is the critical path method (CPM).

CPM allows project managers to determine which tasks are the most crucial for project completion. To find the critical path, a list of all project activities is sorted by their duration and their relationship to each other. Each task that can delay the completion of a project if it is delayed by even one day is considered to be part of the critical path. The longest sequence of critical path tasks will reveal the project’s shortest duration.

Using this method, you can identify all the activities that need to be done in order for your project to finish on time and then find the earliest start and finish dates for each of those tasks. It’s also possible to see how much float is available for each activity, which is important when assigning resources.

While CPM is a powerful tool, it can be challenging to use when the work breakdown structure (WBS) of a project is not clear. It also depends on accurate project duration estimates, which can be difficult to determine for complex projects. This is why it’s important to use a construction project management software that makes this process easier for everyone involved. Fortunately, Tread’s cloud-based solution offers more than just the ability to visualize project schedules; it can help you manage your entire construction operation and keep everything on track.
