TL;DR
Test AI plumbing estimating software with one normal completed project and one difficult project. Freeze the drawings, scope, baseline quantities, pricing rules, tolerances, and deadline before the test. Score extraction, corrections, revision handling, estimate output, auditability, and total estimator time.
What should be frozen before the test?
Freeze the test before any vendor sees the answer key.
Record the drawing set, specifications, addenda, scope letter, accepted takeoff, labor assumptions, material pricing, waste, overhead, markup, exclusions, and output format. Define which quantities must match exactly and where a tolerance is allowed.
Which files should be included?
Use the documents estimators actually receive.
The package can include plumbing plans, risers, isometrics, fixture schedules, legends, specifications, keyed notes, and addenda. Beam AI and Bobyard both document reading several of these file types on their official plumbing pages. A test made from a clean single sheet will not expose the harder plan-reading problems.
Which tasks should every product complete?
Give every product the same sequence.
- Import the complete drawing package.
- Define the plumbing scope and exclusions.
- Extract fixtures, equipment, fittings, and pipe by system and size.
- Identify missing or ambiguous information.
- Apply labor, material, and markup rules when estimating is supported.
- Process an addendum without rebuilding the entire job.
- Export the accepted result in the required format.
- Show the evidence trail for a sampled quantity.
How should results be scored?
Score the accepted result, not the first screen.
Track count agreement, length variance, system assignment, omissions, false detections, correction time, total elapsed time, revision behavior, and export usability. Record whether a human reviewer was supplied by the provider or by the contractor.
What failure tests matter?
Test bad inputs and operational edges.
Upload a low-quality sheet, a revised schedule, an unusual symbol, and a conflicting note. Confirm what happens when the model is uncertain. Test user permissions, deleted items, duplicated imports, export errors, and the ability to retrieve the original source location.
Source ledger
Which primary sources were reviewed?
Provider capabilities and prices are attributed to official pages. Company-published material describes what the provider documents and does not establish independent performance.
Buyer questions
Frequently asked questions
Can a vendor run the pilot for the buyer?
Yes, but label it as a managed demonstration. A buyer-operated test answers a different question about usability and internal review effort.
How many projects are enough?
Two can establish an initial screen, but a purchasing decision should reflect the contractor's project mix and risk. Add more examples when work varies substantially.
Should price be part of the test score?
Keep capability and commercial evaluation separate until technical acceptance is complete. Then compare the first-year cost per accepted project.
What is the final approval gate?
An experienced estimator should confirm scope, quantities, assumptions, labor, pricing, exclusions, and revisions before any bid is issued.
