Jim lists discusses the different types of scheduling systems that have been applied to construction scheduling, including PERT and arrow diagramming, and explains that today the industry uses precedence network diagrams.
- I'm going to continue with the history lesson…just a little bit and talk about the different types…of schedules that we see in construction.…And I'll take just a few minutes to explain why…the different methods have been used over time, and what…some of the limitations are on each one.…First, I'm going to mention, and then we'll skip over,…what I consider to be systems that are important…to the history of planning and scheduling,…but not really used much today.…These are going to include the…Program evaluation review technique, or PERT,…and the arrow diagramming method, or ADM.…
PERT was developed in the late 1950s by the US Navy,…and it's a somewhat complex system that we just don't see…used much in the construction industry.…PERT takes into consideration the problem of uncertainty.…That is, the fact that when it comes right down to it,…when we make a schedule, we are just sort of picking…a number, or a fixed value for each activity duration,…when in real life there is probably an optimistic…time duration, and a pessimistic time duration, and using…
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.
