Explore the nuances of constructing building elevations, ensuring consistency for contractors by maintaining the same scale and datum information throughout various drawings. Understand the importance of accurately calling out dimensions and modifications to prevent mistakes and confusion.
Key Insights
- Building elevations are created at the same scale as building sections, ensuring consistency and reducing confusion for contractors.
- Datum information is key and must be consistent across all plans, sections, and elevations to prevent discrepancies in measurements such as finish grade and top of plate elevation.
- Careful notation is essential in architectural drawings, with dimensions preferably called out only once to avoid potential inconsistencies if changes are made.

The building elevations are being reflected at the very same scale that we use for our building sections. If you look over here on the left, you can see our datums. If I zoom in, you can once again see the very same datum information we had before.
Again, we're trying to make the information consistent for the contractor. You know, we don't want on one plan for it to have a different finish grade and top of plate elevation than on the others. So typically this information is referenced into the drawing so that there's no confusion whatsoever.
And I apologize, I'm starting to talk CAD and BIM. But again, we want to have the same datum information conveyed on the elevations that we have on the section. You can see right here that there's a delta.
What had happened was this is a little chimney that's going on. When we submitted the drawings, we failed to include the two-foot minimum call-out alongside a chimney flue. We bubbled it and put a delta. The same thing is going on for this chimney that's located outside of the deck.
We have the chimney for the living room. We have the chimney that's going on alongside the deck for the exterior deck. On this sheet, just like before, sheet number, sheet name, revision dates, revision information.

These were notes that were added per the last submission. And again, you can see that we have the call out information that's going on right up here. So again, the keynotes here.
One thing you'll notice, and when I zoom in, you will see it says Keynote 1 Typical. And rather than keynoting like crazy on the drawing, by saying Keynote 1 Typical, we only need to include that note one time, and then it's typically understood throughout the building. So again, building information.
Once again, we are showing the vertical dimensions. The horizontal dimensions are conveyed on the floor plan. And again, one of the reasons you want to only reference that information one time in one location is that if, in fact, something changes.
If you, for example, call out a horizontal dimension on the floor plan, and then if you were to come back and call it out on the vertical on an elevation or section, if you forgot to change it in one place or another, you're not in a good situation. So again, what you want to do is to call out dimensions, preferably one time in a set of drawings, and if it's changed, you make the modification to that one location. So again, these are two of the building elevations.
You can see the main part of the house is here. The owner wanted to have a bridge so that it's open to below down here, and this is their guest suite. This is looking at one of the sides of the building.
Here is the guest suite looking at yet another side. Here is what I'm going to call the side elevation to the deck itself, and here is the deck looking from yet another angle. If I go down to the next page, here is the formal front of the house where we have our three garage doors.
You can see the front of the deck. You can see, for example, we have this door feature for the living room. We're showing the front door right here and other windows that are going alongside.
This is the back part of the house back here. So this has been an overview of the building sections, and if you would please spend a little bit of time looking at that information, and we will continue on after you've spent some time with this.
