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 continue with our Level 2 Reflected Ceiling Plan (RCP) dimensions. We’ll dimension the toilet areas, the gym, and a few other spaces, and that should complete the necessary dimensions. I’ll start here.

There are two schools of thought when it comes to showing upright sprinkler protection on an RCP. I’ve worked on projects where some teams show it only on the piping plan, while others include it on the reflected ceiling plan. For the purposes of this course, we’ll include upright sprinklers on the RCP, so we will dimension them as well.

Since they are typical, we only need to dimension the first row and one perpendicular row. I believe we already dimensioned this sprinkler on the Level 2 piping plan, so let’s quickly check. I’ll go ahead and delete this dimension—that’s better.

Let’s finish dimensioning the housekeeping and restroom areas, and we should be all set. Let me take a quick look around.

The corridor is already covered. Down here looks good. We don’t need to dimension the light hazard areas that have ceiling tiles.

We already have a note on the piping plan, so that should suffice. Okay, great.

In the next video, we’ll continue with ceiling elevations and annotations, and we should be finished with our reflected ceiling plans.
