IBC Chapter 29 plumbing check
Helonic is an AI construction drawing analysis platform for plumbing teams checking International Building Code on construction drawings.
IBC plumbing review is a Chapter 29 check of fixture counts, accessible fixtures, and the IPC systems the IBC points to, run on the issued plumbing and architectural sheets before the building department sees them. Helonic reads those sheets together so a restroom that meets the floor plan still fails when Table 2902.1 or Chapter 11 is applied to the occupancy actually drawn.
Helonic checks plumbing drawings against IBC Chapter 29 and the IPC it adopts: occupant-based fixture counts from Table 2902.1, accessible fixtures from Chapter 11, grease interceptors at food service, and storm drainage that has to land on the civil sheets. Each finding cites the sheet and the section so the plumber and the architect can settle the count before plan check.

Why does IBC plumbing compliance matter?
Fixture-count misses and inaccessible restrooms are among the cheapest comments a plumbing desk writes and among the most expensive to fix after framing. IBC Table 2902.1 is occupancy math, not a typical-floor guess, so a mixed-use stack that copies the office count onto assembly space fails at permit. Catching that on the issued set costs a drawing revision. Catching it after the stacks are in the wall costs a chase, a floor drain, and a week of wet trades.
