No more drowning in fixture counts. Sweinstein loves a good mud bath, not a backlog.

Measure on top of the count

After the count, Sweinstein traces pipe runs and totals the lengths per floor. Lengths are worked out exactly from each sheet's confirmed scale. The AI traces; the math is done in code.

Ask about your local code

Ask about the plumbing code for your province or state. Answers quote the code books your company uploads and follow the project's province or state. They are a reference, not legal advice.
