Building data · Fixture Count

Fixture Count overview

Turn a building's rooms into minimum plumbing fixture counts, laid out the way a code summary sheet shows them.

Alpha tool. It's early and still changing: expect things to break, and keep your own copy of anything you can't lose. What alpha means

Fixture Count works out minimum plumbing fixture counts from your rooms. It figures occupant loads from the IBC occupant load table, then fixtures from the IPC minimum fixture table, for the edition you pick. The results come out as the tables a permit sheet shows, ready to export as a PDF.

The counts are planning aids. The code values in the tool are transcribed and still being verified, and states amend these tables. Check them against your adopted code and the authority having jurisdiction, and have them verified by a licensed professional.

The main screen #

From top to bottom:

  • The toolbar. Project ▾, the fixture count's name, Code (the IBC / IPC edition), Male (the share of occupants counted male) and, when the count is linked to a program, the program's chip. On the right: New, Import, Save file and PDF ▾.
  • The tabs: Rooms, Fixture lines, Results and Code tables. Next to them, a one-line summary: total occupants, water closets and lavatories, male and female.
  • The flags: warnings that need you, like code values not yet verified, uses guessed from room names, or rooms with no use.
  • The work area for the tab you're on.

Pick the code edition #

Open Code in the toolbar and pick IBC / IPC 2018, IBC / IPC 2021 or IBC / IPC 2024. Check which edition your state has adopted, and its local amendments.

Male sets the share of occupants counted male. The code's default is an even split; a different split needs the building official's approval.

Start a new fixture count #

The tool opens on its home page. Under Start fresh:

  • Start from a Space Ledger in this project: one room line per program space, and the count stays linked to the program. See Rooms and occupant load.
  • + Blank: no rooms yet.
  • A template: Office floor or Office with a cafe.

You can also click New in the toolbar to clear the screen.

Fixture Count isn't on a project page's + New menu yet. New work starts on this computer only. To file it with a project, open Project ▾ and click Push to a project….

Open existing work #

  • From the tool's home page. Click Tools in the top bar to get there. It lists the count you were last working on and the fixture counts saved in your projects.
  • From Project ▾. The menu lists the fixture counts in your projects.
  • From a file. Click Import and pick a .plumbing.json file. It opens as new work on this computer. Save file saves one.

Who can see it #

A fixture count in a project is shared with that project's people. Viewers can open it and look, but can't change it. See People and roles.

Fixture Count doesn't have the Share / Snapshots button yet, so it has no view-only links or snapshots. Every save is still a version: see Saving and versions.

An AI assistant connected through the AI connector can read your fixture counts, but not change them.
