Discover the intricacies of a foundation plan, including the breakdown of notes, legends, wall sections, beams, and footings. Gain a deeper understanding of how different elements like elevation callouts, control joints, footing schedules and detail references interconnect to form a comprehensive plan.
Key Insights
- The foundation plan includes critical elements such as foundation notes, legends, and wall sections. Specific elements like slab elevation, wall footing, and spread footing schedule are also outlined and referenced in the plan.
- The plan emphasizes the usage of different sections, footings, and beams, alongside their corresponding elements like control joints and grade beams. These components not only help in maintaining the structure but also in guiding the construction process.
- The foundation plan is primarily schematic, implying that although it represents the overall size of the footings, the actual sizes are detailed in the footing schedule. This highlights the importance of careful review and understanding of all referenced details or sections in the drawing.

Let's review page S101A, the foundation plan for part A of the building. Let's zoom down here and look at the notes. We have foundation notes.
We have the legends. There's one that calls out the top of slab elevation. Top of wall footing.
And then for the actual footings themselves, there's a callout that references page S301 and the spread footing schedule. And then also the elevation callout for the top of the footing. Let's just zoom in this area.
You can see that we have a number of wall sections that are referenced. So this is saying look at image four on page S302 to see the section that is cut through here, looking to the left. Another section going through this wall here, looking to the left.
Another section going through this wall here, looking up. You see that we have a footing right here. It references F4.0 on the footing schedule.

And the top of the footing is minus four feet, four inches. Many other sections cut in through here. You can see that the elevation here is also minus four foot four.
We have a footing here, one here, and a very large one here. There's a grade beam that connects this footing to this footing. And it's grade beam number 28.
We have footing number 8.0 on the schedule right here. And again, it's on the schedule that the actual dimensions for the footing will be called out. We have control joints that are going from column to column.
And this is where we actually encourage the concrete to crack so that we don't have random cracks in the concrete. We have control joints here on the angles surrounding the columns. We have a reference to detail on sheet S203, image 5. This is the elevation of the actual slab.
More footings, grade beams between different footings. A section here. A large slab here.
Detail references here. Elevation heights called out here. One of the important things to remember is that the foundation plan is schematic.
In that these footing sizes that are drawn are representative of the overall size of the footings. But the actual sizes are called out on the footing schedule. And we have a lot of references to the details or sections in this particular drawing.
So again, please spend some more time reviewing this drawing. And I look forward to being with you in our next video.
