Have you seen the lesson where we showed you how to use WBS Summary activities to assign resources to whole sections of projects? Then this lesson is also for you. Here’s a slightly different scenario. In this situation we don’t want to assign a resource to an entire section of a project but sort of a sub-section that looks like that. Now, this sub-section is within a WBS. We’d like to assign a resource just to those four activities. Now, of course I could always individually assign that resource to those individual activities but perhaps there’s a better way. I’ll show you that better way in this lesson. Once again we have the Railcar Maintenance Facility project open. And we’re looking at the Maintenance building and some of the structure work that’s going on in the construction of the Railcar Maintenance Facility. I want to bring your attention to couple activities here where we’re doing a lot of concrete work. Okay. In order to do this concrete work, we’ll use a concrete pump to help us pump the concrete to the right places on the site. Once again we have a situation where the concrete pump could be used on many of these activities. And of course, I could assign it individually to each activity if I want it. There is a more efficient way and this is very similar to using a WBS Summary activity. I want to introduce you to a new activity type called a level of effort activity. In a Level of Effort Activity will essentially summarize a number of activities that I specify and then I can apply my resource assignment to that activity. Let’s create one, I’ll show you how it works.
So we’ll add a new activity, this WBS. I’ll just call it level of effort to keep things simple for the time being. I want to renumber it so it shows up right above this guy here so what I’ll do is copy this number in here, paste it in there, and let’s see we’ll make it number 74, 3274. There we go. We’ll go ahead and set this to a level of effort activity type. Now as I said, I would like this activity to more or less summarize these four activities directly below it. The way I can specify which activities to summarize is by using relationships. So we’ll go to our Relationships tab and what I’ll do is add a predecessor to this activity. It has a start to start relationship with the first activity I want to summarize so we’ll go ahead and add, let’s see here, concrete water and we’ll make it a start to start relationship. After that, we’ll assign the successor. And the successor will be the last activity here, the trenches and we’ll make that one a finish to finish. Watch what happens when we reschedule (3:32) the project. Once again as we saw in WBS Summary activities, the activity’s duration is automatically calculated. It’s calculated 40 days. How did it do it?
Well, it said what is the earliest start of the first activity (3:56) arising? Well there it is, April 14th. And then it said, what’s the latest finish of the last activity? And its June 9th. And it put those both there and calculated the duration of those two activities. Let’s have a look at how it looks like on a Gantt chart. I’ll just double click to scroll over and there is my bar. And if you have a quick click you’ll see that it has a start to start relationship with the first activity here and it has a finish to finish relationship here with the trenches activity. So that activity is doing what I call summarizing. It is summarizing the activities below it. Now, the benefit of using level of effort activity, unlike the WBS summary is you can spin across WBS if you want and really WBS doesn’t play any role in this activity type unlike WBS Summary activity types. Once again we built the perfect activity to assign a resource 2. So we’ll go ahead and add our Concrete Pump. Click to assign, there’s my concrete pump. It’s working on this activity for 40 hours per day and let’s make it available a little bit longer than that. We have a price of $675 per hour. So this activity, more or less, exist so that I could assign some high level resources like a concrete pump to it rather than assigning it to the individual activities below. I could also use this activity to assign other resources or even expenses too.
Before we wrap up this lesson, I think it’s important to let you know that this level of effort activity type also has another name because it seems to hang between two activities it’s often been called a “Hammock”. As you work in your industry if you find individuals referring to a hammock in Primavera you can know that that is also called a Level of Effort activity. So now you can add Level of Effort activity to your arsenal of tools to go out and build excellent resource loaded schedule in Primavera. Good luck!
