How to Do a Door Takeoff from PDF Drawings Accurately

To understand how to do a door takeoff from PDF drawings, count every scheduled opening on the floor plans, match each door mark to the latest door schedule, and record the leaf, frame, finish, rating and ironmongery requirements. Reconcile discrepancies across plans, elevations and specifications before transferring verified quantities into the estimate or bill of quantities.

Key takeaways

• Count openings and leaves deliberately: one double-leaf opening may require two door leaves but only one frame set.
• Match every plan marker to the door schedule and specification, rather than pricing from symbols alone.
• Separate doors by material, size, fire rating, acoustic rating, frame and ironmongery set.
• Record drawing revisions, assumptions and RFIs so quantities remain auditable.
• Use consistent count colours and descriptions to expose missing, duplicated or unclassified doors.

What is a door takeoff?

A door takeoff is the process of extracting the quantities and specifications needed to price a project’s doors and associated components. Depending on the subcontract package, it may cover door leaves, frames, linings, glazing, architraves, thresholds, seals, access-control equipment and ironmongery.

The important unit is not always simply “each”. An estimator may need to report openings, frame sets, leaves and ironmongery sets separately. For example, ten openings could contain twelve leaves if two openings have double doors.

A useful takeoff also preserves the source of each quantity. Each item should be traceable to a floor plan, door schedule, elevation, detail or specification clause, together with the relevant drawing revision.

Which drawings do you need for a door takeoff?

Begin with the latest architectural tender or construction issue. Check the drawing register before measuring because a polished door schedule is not useful if it belongs to an earlier revision.

The normal document set includes:

• General arrangement floor plans showing door swings and door marks
• The door schedule, sometimes split by level, zone or door material
• Internal elevations and room data sheets
• Door, frame, threshold and head details
• Fire strategy and compartmentation drawings
• Acoustic plans or performance schedules
• Ironmongery and access-control schedules
• Architectural specification and preliminaries
• Revision notes, revision clouds and tender addenda

Structural openings may also appear on builders’ work or setting-out drawings. These dimensions can help identify conflicts, but they should not silently replace the scheduled door size. If the documents disagree, record the issue and raise an RFI or tender query.

How to do a door takeoff from PDF drawings step by step

1. Confirm scope, issue status and measurement rules

Define exactly what your package includes before counting. Clarify whether you are pricing supply only, supply and installation, or a complete doorset including frames, ironmongery, seals and making good.

Review the employer’s requirements, specification and bill of quantities. If the project uses NRM2, confirm how doorsets and associated work have been classified; the tender documents may nevertheless require a project-specific breakdown.

Create an exclusions and assumptions list at the outset. Items such as automatic operators, security interfaces, builder’s work, decorations and final keying are frequent scope boundaries.

2. Load and organise the PDF drawing set

Use the latest floor plans and schedules in a browser-based construction takeoff workspace. Name each drawing by number, title and revision so an older plan cannot be mistaken for the current issue.

Although a pure door count does not depend on scale, calibration is still valuable when checking clear openings, wall thicknesses or travel distances. Calibrate against a stated dimension or scale bar, confirm whether the sheet uses millimetres or metres, and test a second known dimension before relying on measurements.

3. Build count categories before counting

Create count items that reflect the detail needed for pricing. Counting every opening into one generic “door” category saves time initially but creates substantial rework when rates differ.

A practical structure might use the scheduled type and rating, such as:

• D01: timber single leaf, non-fire-rated
• D02: timber single leaf, FD30S
• D03: steel double leaf, FD60S
• D04: glazed aluminium entrance doorset
• D05: riser or service-cupboard doorset

Give each category a distinct colour. Use descriptions that remain understandable when exported to the estimate, rather than unexplained labels such as “red count”.

4. Count every opening on the floor plans

Work methodically by building, level and zone. Follow a fixed direction around each plan—for example, clockwise from the main entrance—and place a count marker directly beside every door mark.

Record unscheduled doors separately instead of guessing their type. Likewise, flag scheduled door marks that cannot be located on a plan. A completed level should have no unmarked door symbols and no unexplained schedule entries.

Pay particular attention to:

1. Double-leaf, unequal-leaf and leaf-and-a-half doors
2. Sliding, folding, revolving and automatic doors
3. Cupboard, riser, access-panel and service doors
4. Doors shown beneath staircases or in congested cores
5. Repeated apartment, hotel-room or healthcare-room types
6. External gates or shutters that resemble door symbols but belong to another package

5. Reconcile counts with the door schedule

The plan proves that an opening is present; the schedule describes the doorset. Match every counted marker to its scheduled door reference and compare the total number of occurrences.

Do not assume door marks are unique. A notation such as D12 may identify a type used 18 times, or a single numbered opening, depending on the project’s naming convention. Determine the convention before using the schedule’s row count as the quantity.

Where plans and schedules differ, create a reconciliation log containing the door mark, plan quantity, schedule quantity, affected drawing references and proposed estimating assumption. This makes the tender risk visible and gives the design team a precise question to answer.

6. Extract the specification of each doorset

For each type, record the properties that affect material, labour or supplier quotations. These usually include:

• Leaf configuration, handing and opening direction
• Structural opening, frame size and leaf dimensions in mm
• Leaf and frame material
• Fire rating, such as FD30S or FD60S
• Acoustic requirement, commonly stated in dB or Rw
• Glazing type, aperture and safety classification
• Finish, veneer, laminate, paint system or powder-coat colour
• Frame profile, architrave, lining and wall thickness
• Threshold, smoke seals, intumescent seals and perimeter seals
• Ironmongery set, access control, hold-open device or door closer

Treat missing performance data as a query, not an invitation to select the cheapest interpretation. Fire resistance, smoke control and accessibility can change the complete doorset specification.

7. Calculate related quantities

Use the count to derive associated materials only where the scope and specification support the calculation. Keep formulas visible in the worksheet or estimate.

For a 900 mm by 2,100 mm single leaf painted on both faces, the gross leaf area is 0.9 × 2.1 × 2 = 3.78 m² before any agreed deduction for glazing. Do not use this shortcut if the painting specification measures edges, frames or factory finishes differently.

8. Apply waste and build the estimate

Doorsets are normally counted as discrete items, so a blanket percentage waste allowance is rarely an adequate substitute for reviewing procurement risk. Apply allowances only where they are justified—for example, cutting waste for architraves or spare ironmongery required by the specification.

Build rates from the actual scope: material, delivery, unloading, installation, adjustment, protection, testing and commissioning where applicable. Separate expensive variants rather than averaging fire-rated, acoustic and standard doors into one rate.

Solid Takeoff’s measurement and estimating features can keep quantities and cost build-ups together, while its practical estimating guides provide further workflow guidance.

9. Quality-check and issue the takeoff

Review each level at a useful zoom and compare category totals with the door schedule. A second pass should focus specifically on dense cores, mirrored layouts, revision clouds and non-standard symbols.

Before issuing the takeoff:

• Confirm drawing numbers and revisions
• Check that every marker has a category
• Compare openings, leaves and frame-set totals
• Review zero-quantity and unusually low-frequency types
• Resolve or list all unlocated schedule references
• Attach assumptions, exclusions and RFI references
• Export a clear summary by level and door type

What should a door takeoff include?

A pricing-ready door takeoff should contain enough information for another estimator or supplier to reproduce the scope. At minimum, include the source drawing, level, location, door mark, quantity, leaf arrangement, dimensions, material, performance rating, finish, frame and ironmongery set.

Add columns for status and notes. Useful statuses include verified, assumed, provisional and queried. This prevents unresolved design information from appearing as settled fact in the estimate.

The final summary should distinguish between:

• Number of openings
• Number of leaves
• Number of frame or lining sets
• Quantity of each ironmongery set
• Measured accessories in linear metres or m²
• Provisional or excluded items

Why does the door schedule not match the floor plan?

Plans and schedules often develop at different stages of design. A door may be added to a revised plan without reaching the schedule, or a deleted opening may remain as an obsolete scheduled row.

Other causes include duplicated door marks, phased drawing issues, inconsistent type-versus-instance numbering and doors concealed beneath annotation. Revision clouds help locate recent changes, but they do not prove that every consequential schedule amendment has been made.

Use a three-way check between the plan, schedule and specification. Where the intended scope remains uncertain, price a stated assumption and record the difference as a tender query rather than concealing it inside the rate.

Common mistakes to avoid

Counting symbols without reading their references

Two identical swing symbols can represent doorsets with different fire, acoustic or security requirements. The door mark controls the classification, subject to confirmation against the schedule and specification.

Confusing openings with leaves

A double door is often one opening, one frame set and two leaves. Label the unit of every total so suppliers and commercial teams know precisely what has been counted.

Assuming every PDF page uses one scale

Plans, elevations and details may have different scales, and a single page can contain multiple detail scales. Calibrate the relevant viewport before checking dimensions and never transfer a calibration blindly between drawings.

Missing doors in repeated layouts

Repeated rooms can create false confidence. Count each occurrence unless the drawings explicitly define a repeat multiplier, then verify mirrored arrangements because handing and ironmongery may change.

Ignoring revisions after completing the takeoff

When a new issue arrives, identify changed sheets and inspect revision clouds, notes and schedule amendments. Preserve the original takeoff, document the revision comparison and update affected quantities rather than overwriting the audit trail.

Pricing unspecified doors as standard

An unscheduled opening may still require fire, acoustic, security or accessibility performance. Put it into a clearly named provisional category and raise an RFI instead of silently assigning a standard doorset.

How to do a door takeoff from PDF drawings faster without losing accuracy

Speed comes from structure rather than hurried counting. Prepare reusable count categories, use consistent colours, work in a fixed sequence and reconcile each level before moving to the next.

A browser-based workflow also avoids dependence on desktop-only estimating software, which is useful for teams working on Mac as well as Windows.

FAQs

How do you count doors on a PDF plan?

Calibrate the PDF when measurements may be required, then place a count marker on every door reference shown on the floor plan. Assign each marker to a door type or schedule reference, count each leaf separately where required, and reconcile the totals against the door schedule.

What information should a door takeoff include?

A door takeoff should record the drawing reference, level, door mark, quantity, leaf configuration, dimensions, material, fire and acoustic ratings, frame, finish and ironmongery set. It should also identify exclusions, assumptions and discrepancies requiring an RFI.

Should door quantities come from the plan or door schedule?

Use the floor plan to establish whether each opening exists and where it is located, then use the door schedule and specification to define what belongs in that opening. Neither document should be accepted without comparison because omitted marks, duplicate references and revision mismatches are common tender risks.
