Dimensioning Upright Sprinklers in Level Two RCP: A Comprehensive Guide.

Dimensioning Upright Sprinklers in RCP: Best Practices and Considerations

Discover key concepts and techniques for drafting RCP dimensions, as well as working with upright protections on a reflected ceiling plan (RCP). In this article, we explore different dimensions in areas such as toilets and gyms, and how to properly annotate them on your plan.

Key Insights

  • The article offers instruction on properly dimensioning various areas of a building, including toilet areas and gyms, on a reflected ceiling plan (RCP).
  • While there are differing opinions on whether to show upright protections only on the piping plan or also on the RCP, this guide recommends displaying them on the RCP and dimensioning them accordingly.
  • The article emphasizes only needing to dimension the first row of a typical area, and then another row in a different direction, reducing the complexity and time required in creating the plan.

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.

All right, we'll be continuing on with our level two RCP dimensions. We'll do this toilet areas, the gym, and a few other areas, and we should be good with our dimensions. So I'll start here.

Now there are two schools of thought about showing upright protections on an RCP. I have worked with and seen some showing this only on the piping plan and some showing it on the reflected ceiling plan. For the purposes of our course, we'll be showing our upright sprinklers, so we'll be dimensioning these as well.

Now since they're typical, we'll only have to do this first row and then another row in the other direction. Now I believe we did have a dimension for this sprinkler on the level two piping plan, so let's just check that real quick. I'm going to go ahead and get rid of this.

That's better. Let's just finish with the housekeeping and restrooms, and we should be good. Okay, let me just take a look here.

Got this corridor already. Down here, we're good. These light hazard areas, we won't have to worry about dimensions in the ceiling tile areas.

We've already got our note here on our piping plan that we should be good. Okay, great. So in the next video, let's continue with some ceiling elevations and annotations, and we should be done with our reflected ceiling plans.
