Discover key insights into the importance of civil engineering drawings, specifically focusing on the demolition plan. Understand the significance of property lines, keynotes, spot elevations, and the procedures for indicating what needs to be removed during a demolition project.
Key Insights
- The demolition plan provides a detailed overview of the site, including property lines, keynotes, and the elements that are slated for demolition such as buildings, vehicular concrete, and pedestrian concrete.
- Additional considerations are often included in the plan, like project silt fencing to contain waste within the construction site, special permits for street closures, and the indication of construction entrance points.
- Spot elevations are also mentioned, which specify the existing site levels above sea level, providing crucial data for the demolition and subsequent construction process.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Let's begin reviewing the first of our civil engineering drawings, the demolition plan. You can see we have the site right here. The property lines are in purple along the edge.
There's a keynote over here that shows what's being demolished. So there are buildings that are being demolished, vehicle concrete, and pedestrian concrete. One thing that's being required more and more in projects is that there would be project silt fencing, which keeps any garbage that happens to be coming off the construction site within the site itself.
So let's zoom into this area and read some of the demolition notes. Again, here are the legends for what's to be removed. Concrete, covered walk, vehicle concrete, and buildings.
And then there are notes like remove existing brick pavers, remove curb, remove exterior piping, remove exterior fencing, and so on and so forth. So as we pan around, you'll see the property lines, and you'll see the property line itself, and then right next to it, the angle in the direction of the property line. And in our next video, we'll be talking about meets and bounds, which are how civil engineers actually create their property lines.
So again, information to be deleted, keynotes, property lines, and also spot elevations. So you can see that this area right here is 5.11 feet above sea level right there. It's 4.19 feet above sea level right there.

So they're just calling out the existing site spot elevations. The actual construction site includes what is in yellow, and so the contractors were required to get special permits to close off the streets so that they can have access to more than just the existing property. It's a fun drawing.
It's very informative. Again, we have property lines. We have indications of buildings, vehicular concrete, pedestrian concrete to be removed.
We have spot elevations. We're showing the extents of the construction area. And there's also a note down here that says this will be the entrance to the construction site.
So please feel free to spend some more time with this drawing and enjoy. I'll see you in our next vid.
