Jim shows several examples of two-dimensional plan views and explains that a plan view is any view looking at the structure from the top down, or from directly overhead. Plan views include floor plans, foundation plans, and framing plans. Plan views contain dimensions and measurements.
- [Man] We're going to start with the basic plan view of, in this case, the first floor of this house, which is shown on Sheet A105. When I say plan view, many people will think floor plan, but that's not actually a complete description. So yes, a floor plan, like we're showing here, is an example of a plan view, but there are many sheets in this set of drawings that are not floor plans that are also examples of a plan view. So really a more accurate description of the term plan view, would be a top-down view, or a view looking at the project from overhead.
The classic definition of a plan view is just that the plan view can be thought of as taking the building and making a horizontal cut through it and then when you look down at the result from the top, that's a plan view. So, let's take a look at some examples. Again, we're already on our first floor plan, Sheet A105 and like I said, this is the floor plan and it's a good example of a plan view. We are looking at the house and the garage from the top down. If we zoom in and scroll around, we can see that the plan view really presents us with a lot of information.
There's a lot of information on this drawing, right? We can see where the stairs go. We have dimensions here at the bottom that give us dimensions from center line of window to center line of window. So we know exactly where to position these windows when we're building this wall. We have information that tells us the sizes of the counter in the kitchen. We have information that tells us what these rooms are in this case because it is the floor plan. So this is the dining room. This is the living room.
This is the office or optional bedroom four and over here we have the garage. Again, this is a great example of a top-down plan view but let's look at a couple of more in our set of drawings. I want to go ahead and go to the foundation plan. Right now, we're looking at what would be a horizontal cut probably about 20 inches up from the floor of our house. That's what we're seeing in this view. If I drill down a little bit more to the foundation plan and zoom in, you can see I still have the same outline of my structure but I've gone a little bit deeper and now I'm looking at a horizontal cut through the foundation walls of this house.
Instead of things like rooms and stairs, I'm looking at foundation walls and footings and we looked at some of these footing lines and foundation wall lines in an earlier segment. But you can see that this is still a plan view because I'm looking at it from the top down, I'm just presented with a completely different set of information because it's taken at a different elevation in the building. So again, instead of rooms and counters and stairs, I'm looking at footings and foundations for things like columns that are going to support the walls above.
Let's take one last look at another type of plan view. We're going to scroll down to our civil drawings and we're going to open up Sheet C101, page 83 in our digital drawings and this is a plan view and it's a plan view because again, we're looking at this project from the top down and this is just a plan view of the existing site that tells us what's there right now. Since it's a civil drawing, it focuses on things like what are the elevations and what's the terrain look like right now.
But again, it's a plan view because we're looking at it from the top down. Just to get you oriented, this is the street that surrounds the site. This whole square is the piece of property where we're eventually going to build the house. Again, just remember, when we use the term plan view, we really just mean any top-down view. So the plan view can present you with a great deal of information, but it is still just a two-dimensional look at something from directly overhead.
Since the structures we build have more than just two dimensions, we're going to need more than just this plan view to get a really detailed look at the structure. So let's continue on and see what some of these other views look like.
In this course, learn how to read construction drawings. Jim Rogers helps you acquire this important skillset by taking you through the different components that make up construction plans, and helping you understand the language of construction drawings. He covers types of views, highlights different kinds of construction drawings—including architectural drawings, electrical drawings, and plumbing drawings—explains how to read general notes, and more.
