One apartment plan shows eight doors. The same layout appears six times. That sounds like an easy count, until an accessible variant changes the layout, a second sheet repeats the same view, or a door mark cannot be matched to the schedule.
For door and window estimators, the time-consuming part is often keeping these details connected. You move between floor plans, schedules and quantity sheets, checking whether each number still describes the right opening.
AI-assisted door and window takeoff can help organize drawings, extract schedule information and count openings. The useful result is a quantity list you can trace back to the plans and review before pricing. Here is how that workflow works, using FlomaticAI Bidder and the Addison sample project.
What is a door and window takeoff?
A door and window takeoff identifies the openings within your scope and records their quantities and relevant attributes. Plans show locations; schedules and details help establish marks, sizes and product requirements. The takeoff supplies quantities for an estimate. Pricing those quantities and accounting for the rest of the bid is a separate step.
Start with the right drawings and schedules
Before running a count, check the drawing issue, addenda and scope. Identify the unit plans, building plans, schedules and details that apply. Keep revised sheets distinguishable from the versions they replace.
In the Addison example, the team uploaded two architectural PDFs containing 50 pages. Bidder classified the sheets so an estimator could navigate the package and inspect individual source pages. Classification controls allow the reviewer to correct a sheet that belongs elsewhere.
Extract the schedule without losing the source
Bidder extracted 29 door schedule rows and five window schedule rows from Addison sheet A601. Those 34 records describe schedule information; they are not a count of 34 physical openings. A schedule may group repeated items or list individual instances, so check what each row represents. Autodesk’s scheduling guidance illustrates this distinction between grouped rows and instance counts.
Review marks, dimensions, materials and any required attributes against the source. In the captured Addison extraction, a partial-page warning and an unreadable secondary window table still needed attention. An empty field should send you back to the drawing, not become an assumption that the requirement does not exist.
Count openings on the plans you actually need
A sheet can contain several floor plans, details or repeated views. Define the area being counted before accepting the result. In Bidder, the Takeoff workflow separates page selection, plan cropping and opening counts. Addison produced 27 approved plan crops from 14 selected pages.
Look at the markers as well as the total. Does each marker correspond to an opening? Is its mark readable? Has the same opening been counted on both a unit plan and a larger building plan? A plausible total can still contain an omitted opening and a duplicate that cancel each other out.
Drawing-linked counts are already part of conventional digital takeoff: Bluebeam, for example, documents manual counts, visual-search counts and location-based grouping. When evaluating AI assistance, look at how easily you can inspect and correct its work, as well as how quickly it produces a first pass.
Keep openings and supplied components distinct
Decide what each quantity means. A door opening may require more than one leaf, plus a frame and a hardware set. Do not copy an opening total into every supply line without checking the schedule and your package scope.
Check repeated units before multiplying quantities
Repeated layouts can save substantial counting time, provided you verify the representative plan and the number of times it occurs.
Accessible variants deserve a separate check. If a variant is already included in the base-family count, adding it again overstates the number of units. Common areas, clubhouse plans and maintenance buildings also need their own scope check; they do not necessarily follow the apartment multiplier.
Keep a breakdown by building, unit type and opening mark. That makes a changed layout easier to update without rebuilding the entire count.
Resolve count and schedule differences before pricing
A mark in the schedule but absent from the selected plans is a question to investigate. It may belong to another area, an alternate or a revised drawing. Likewise, a counted opening without a readable mark needs a source check before you assign a product.
The captured Addison validation illustrates this review step. It flagged missing marks, unmatched schedule references and plans awaiting verification. Work through the relevant source pages, correct the inputs or document the clarification, then compare the quantities again.
Where FlomaticAI Bidder fits into the bid
FlomaticAI Bidder is built for door and window bidders and estimators. Its guided workflow connects document upload, indexing, schedule extraction and opening takeoff with specification, compliance and pricing review, followed by final output. The embedded Bidder assistant supports project-related questions along the way.
Takeoff is one part of that process. Before preparing the bid, confirm the product requirements, supplier costs and assumptions that apply to your package. The FlomaticAI team has verified that Bidder can generate a report after finalization. An earlier incomplete report screenshot should not be mistaken for the finished result.
What the Addison team reported
For its completed Addison testing, the FlomaticAI team reports reducing work that traditionally took three days to approximately 15 minutes, with 99% accuracy. These are team-verified results for that evaluation, rather than an independently audited benchmark or a guarantee for every plan set.
The earlier screenshots used in this article show work in progress. They explain the interface and review steps; they do not measure the completed run. The separate 844.40-second activity trace measures indexing only and is not the basis for the end-to-end timing claim.

Frequently asked questions
Can AI count doors and windows from PDF plans?
AI-assisted software can help detect and count openings in PDF drawings. The result still needs checking against plan boundaries, readable marks, repeated layouts and the relevant schedules. In Bidder, page selection, cropping, counting and validation are separate steps.
Is a door schedule the same as a door takeoff?
No. A schedule describes openings or types and their attributes. A takeoff establishes quantities for the defined scope. Some schedules list individual instances and others group items, so the number of rows alone does not establish how many openings to supply.
How do you avoid double counting repeated apartment layouts?
Verify one representative layout, confirm how often it occurs and keep unit and building quantities separate. Check whether accessible variants are already included in the base count. Avoid counting the same physical opening again on a different drawing view.
What should I do when plan counts and schedules disagree?
Return to the source sheets. Check the mark, drawing revision, included area and possible duplicate views. Correct the takeoff or obtain clarification, then rerun the comparison before approving quantities.
Does Bidder create a final bid report?
Yes. The FlomaticAI team has verified report generation after finalization. Reviewed quantities, product requirements, pricing inputs and proposal settings remain important to the completed bid.
Does Bidder handle every construction trade?
Bidder’s current stated scope is doors and windows. This article does not describe structural, electrical, plumbing or other trade takeoff capabilities.
