Jim explains that once the activities with float time have been identified, the process of finding the critical path in the construction schedule becomes easy. Jim explains the importance of recognizing activities on the critical path, and notes that this is also called the critical path method (CPM).
- With our somewhat lengthy previous discussion…about early and late start and finish times,…and how to calculate float,…the discussion on identifying critical path becomes easy.…Actually, I already defined it in the last video.…Any item that has no float, is on the critical path.…Any item that shows an early start date…as being the same as the late start date,…means it has no float.…If it starts late,…then the project end date will be affected,…and that means the activity is on the critical path.…So, what's the big deal?…Well, it's really important on a construction project…to identify items on that critical path,…and to recognize that if these items…don't start and finish on time,…the overall completion date will be affected.…
You do not want to ignore this early on,…and then find yourself at the end of a project…facing liquidated damage fees that the owner's…going to deduct from your payment for not finishing on time.…When a critical path item starts or finishes late,…you have to make adjustments or accept the probability…
This course identifies the steps needed to develop a proper plan, and demonstrates how that plan is transformed into a construction schedule. Throughout the course, instructor Jim Rogers shares examples of his own successes and failures in the areas of construction planning and scheduling, so as to lend real-world context to the concepts he covers.
