AI for Plumbing Takeoff: Fixture Counts & Pipe Runs from PDF Drawings
Civils.ai helps your team prepare a draft plumbing takeoff from plan PDFs—fixture counts, pipe run lengths, and clear references—so you can build sharper bids faster, with people in control at every step.
Why Estimators Use AI Assistance for Plumbing
Quicker start
Get a prepared draft from your PDFs instead of starting counts and lengths from scratch every time.
Clear traceability
Draft outputs point back to the exact plan pages and notes, making checks and clarifications simple.
Easier re-issues
When drawings change, it’s faster to update and re-issue a draft than to re-measure everything manually.
How It Works (Simple, Human-Centred)
- Upload your PDFs — Add plumbing plans, riser diagrams, fixture schedules, legends, and any relevant spec pages.
- Write your prompt — For example: “Prepare fixture counts by type and level; measure cold, hot, return, sanitary, and vent runs where shown; note any assumptions.”
- Click “Run” — Civils.ai begins preparing a draft plumbing takeoff from the documents you provided.
- QA review & adjust — Your QA team reviews the draft, fixes anything that needs attention, and confirms inclusions/exclusions.
- Share with confidence — Release the reviewed quantities and notes to stakeholders with clear references back to the source PDFs.
Important: Civils.ai assists with preparing bids. It does not deliver a 100% automated takeoff—final numbers are reviewed and approved by qualified people.
What the Draft Can Cover
The aim is a clean starting point for pricing—prepared directly from the drawings and schedules you upload.
Typical items
- Fixture counts by type, room, and level (as shown in plans/schedules)
- Pipe run lengths for cold, hot, return, sanitary, and vent where routes are shown on plans
- Risers/stacks counts and locations when indicated on riser diagrams
- Simple summaries by floor or zone to support pricing discussions
How quantities are determined
All counts and lengths come from the PDFs you provide. The system does not “interpret” beyond what appears in your drawings, schedules, and notes.
What to Expect (and What Not To)
What you can expect
- A draft plumbing takeoff to help your bid
- References back to the exact plan pages and schedules
- Faster internal reviews and fewer back-and-forths
Limitations to note
- Not a 100% automated takeoff—human QA remains essential
- Quantities are strictly based on what’s shown in your PDFs
- No calculation of pipe gradients or complex 3D routing
- If sizes, routes, or allowances aren’t shown, your team sets and confirms them during review
FAQ
Can we define inclusions and exclusions?
Yes. Use your prompt to state how you count runs and fixtures (e.g., include branch lines, exclude final connections). Your QA team confirms before release.
Where do pipe lengths come from?
From the routes shown on the plan drawings. If a route isn’t shown, your team can set an allowance during QA and note it clearly.
Are pipe sizes captured?
If sizes are shown in the drawings or schedules, they can be included. If not, your team can add them during QA before issuing numbers.
Is this useful during busy bid periods?
Yes. You get a draft quickly, then your team reviews, adjusts, and prices—no starting from a blank page.
