Join Josh Modglin for an in-depth discussion in this video Cut and fill analysis, part of InfraWorks 2018 Essential Training.
- [Narrator] In our last exercise we started adjusting our vertical design, our profile, but we're still not exactly sure about the cut and fill analysis. So we're going to actually adjust or change the type of road that we're working with, from local to just being portions or components that we can individually make adjustments to of the actual corridor, but still have the vertical and horizontal design. When we do so it gives us the ability to run some analysis. So first off, notice that I'm in the proposal component road start and so I'm going to add a new proposal.
Component road end. And then I'm going to select my road design and right click and notice one of the options is to convert to component road and we're just going to just convert automatically. And you notice when we did that it turns it and provides a lot more information and what we're going to do, what is the difference here. Notice we have component roads, highways roads, arterial roads, collector roads so all of these of course provide different types of controls and functionality.
The component road, what that does is it breaks down the design so it's not just a local road and we apply a style to it, but we have different elements of the road. Notice now I can select this lane or I can select this lane. I can select the green space. I can do all of these different portions and deal with each component of the road somewhat individually, but also notice for the job card that there is a cut and fill analysis. There's other analysis such as material quantities right here in the job card.
What we're going to do is we're going to select cut and fill. When we do it says, well there's a few different things that you can set first. You can specify the settings. One of the things you can change in the settings is how often do you do the calculations. So think of this as a means to be able to set how many cross sections you have and that's of course the analysis method that's being used. And are there other locations that you want to increment or run an analysis? And then the average end area is the method used.
I'm going to go ahead and close that and we're going to run the analysis hitting the play button to compute earthwork quantities. When we do it doesn't take much time at all and notice we have 41,000 cubic yards of cut and 7,600 cubic yards of fill so we have some design adjustments still left to do. One of the design adjustments we're going to do is we're just going to again select our profile. It means we actually have to pick on that profile a little bit closer.
Right click and show profile view and when we do we can make those adjustments. For example, should we slide this and give us a little bit more fill in that area to make that adjustment. Of course when we make that adjustment it automatically shows up on the screen and our cut fill analysis goes blank, but easy enough to just compute again and now we've completely switched. We have not enough cut to balance it out. So as you go through you're able to quickly run an analysis on your design and remember InfoWorks is a 30% design software.
It's used to help us get to the point where we can start doing planned production and really dig in to our design and look at how much design development we're able to do right within InfoWorks. Now I'm going to close this down and notice one of the other options that we have is show cross section as well. And this is something that's just be added with this version and you literally just slide this bar up and down as you need to get the right look or feel of your cross section.
The reason why this cross section is only available for components is because, well, there's no reason to look at a cross section otherwise and because it's always going to be the same cross section for a style, but because we're in a component road we can apply different components, or make changes to the width of this lane versus the styles or design that we have that we're applying. So a lot more control, but of course it also means there's a lot more settings that we have to keep up with.
So often times, as you saw, I start with local roads and get a little bit closer to where I want to be and then the component roads gives me the ability to make additional adjustments and analysis.
