Crafting construction documents is a critical step in the building process, specifically when it comes to creating the Level 1 Reflected Ceiling Plan. This guide discusses the process of dimensioning and annotating the plan, highlighting the importance of showing correct dimensions for types such as smooth hard lid, jitboard type ceilings, and the placement of sprinkler systems.
Key Insights
- The creation of construction documents requires detailed dimensioning and annotating of elements such as the Level 1 Reflected Ceiling Plan. This includes specific elements like ceiling tiles, ordinary Group 1 and Group 2 hazard rooms, and uprights that need to be dimensioned.
- Dimensioning is essential for the plan reviewer to accurately know the location of different elements. For example, the position of sprinkler systems is crucial, and it involves a process of unpinning and moving room tags, ensuring leaders are turned on, and reviewing the dimensions.
- Incorrect spacing or missing elements can be detected during the dimensioning process. In the instance of a sprinkler being too far from the wall, an additional one may need to be added to adhere to the standard spacing rules. This process involves copying the original, setting it at the correct level, and connecting it to the branch line on the piping plan.

All right, continuing with creating our construction documents, let's begin by dimensioning and annotating our Level 1 Reflected Ceiling Plan. As you can see in the portion that's already done, if we have ceiling tiles, fortunately we don't have to worry about dimensioning—however, that's only if they are light hazard. We do have some Ordinary Group 1 and Group 2 hazard rooms, which for our purposes means we're going to have to show some dimensions, and we will be showing dimensions in the smooth hard lid, gypsum board-type ceilings.
So let's get started. The first thing I want to do is note that we have some uprights that we need to dimension as well, but they're currently hidden. So let's go ahead and reveal hidden elements.
If we zoom in, make sure when you select it that it's the sprinkler upright. Hold Control and select these three, then right-click and choose Unhide in View > Elements. Now we can exit Reveal Hidden Elements mode. OK?
We can begin here. We'll type DI and find this, hit TAB to our sprinkler. All right, now you'll notice we have some things in the way, so we can move this over. Currently, our Room Tags are pinned, so we can go to Pinned Elements and unpin them. Now we can select them, and move them from here. As long as the leader is turned on, it will still be visible. If we turn off the leader, one will still be automatically added.
Okay, moving on—let's go down to these sprinklers. Oops, there's one more sprinkler here. DI. This process is critical for the plan reviewer to determine the location of our heads. Our dimensions are critically important, so we must go through the process of dimensioning each one.

Let’s stay on the Dimension tool, and make sure we're not duplicating any dimensions. Unpin that as needed. Now let’s go ahead and make sure all our elements are pinned again—we don’t want to accidentally move them. We’ll unpin them again when needed.
Now let’s go to this corridor area. The reason we show our dimensions is so that the installer will know the location, and the plan reviewer will know that we’re not overspaced. This is also a good opportunity to check for any missing sprinklers.
If you recall, 7'6" in general is the maximum spacing off of a wall, or 15 feet between heads. So in this case, this sprinkler is too far. It looks like we'll need to add another one. So, let’s go to this one, copy it, and move it over 12 feet.
Remember, it’s not automatically hosted. This one is on Level 1 at 10 feet, so make sure to choose Level 1, and set it to 10 feet. Now it's very easy to connect this to a branch line. So let’s go back to our Level 1 piping plan.
Here is the sprinkler we just added. All we need to do is select it, connect into the branch line, remove the temporary sprinkler, and ensure the pipe is all 1".
