A door takeoff is more than copying marks and sizes from one schedule. Information is distributed across floor plans, life-safety drawings, wall types, elevations, details, specifications and hardware sets.
Quick answer
Create one row per opening and trace every requirement to a drawing or specification source. Record conflicts as RFIs instead of making hidden assumptions, and control revisions so quotations remain comparable.
Why door takeoff from architectural drawings matters
A disciplined takeoff prevents missed frames, wrong swings, unpriced ratings and duplicated openings. It also creates the data foundation for shop drawings, procurement and installation.
Start with a controlled drawing set
Record issue date and revision for every source. Overlay addenda and bulletins before counting openings, and keep deleted or relocated marks visible in the change log.
Build an opening-level matrix
Capture mark, location, quantity, leaf, frame, wall, size, swing, rating, glazing, louver, finish and hardware set. Never combine openings until their requirements are confirmed identical.
Cross-check plans and schedules
Walk every plan mark back to the schedule and every schedule row back to a plan. Use elevations and details to resolve pairs, sidelights, frame profiles and finish conditions.
Separate facts from assumptions
Flag missing wall thickness, rating conflicts, unknown hardware and unclear dimensions. Price alternates transparently and issue RFIs before release.
Project checklist
| Item | Decision to record | Why it matters |
|---|---|---|
| Document control | Drawing/spec revision | Sets bid basis |
| Opening identity | Mark, location and quantity | Prevents duplicates |
| Assembly | Door, frame, wall and rating | Defines product |
| Accessories | Glazing, louvers and hardware | Captures scope |
| Exceptions | RFI or stated assumption | Controls risk |
A practical delivery workflow
- Define the opening. Confirm location, room use, wall, size, swing, ratings, exposure and owner operations.
- Coordinate the assembly. Review leaf, frame, glazing, hardware, seals, controls and finishes as one system.
- Freeze approved information. Resolve comments and RFIs before fabrication; record revisions in the door schedule and shop drawings.
- Verify delivery and installation. Inspect labels, packing, dimensions, preparations, clearances, operation and maintenance records.
Information to send with an RFQ
A reliable quotation needs opening-level data, not only total quantities:
- Current architectural and life-safety drawings
- Door, frame and hardware specifications
- Door and frame schedules
- Wall types and finish plans
- Addenda, RFIs and approved substitutions
For overseas supply, also state the destination, packing method, required certificates, delivery sequence and approval milestone.
Frequently asked questions
Should identical door marks be combined?
Only after confirming size, wall, handing, rating, finish and hardware are genuinely identical.
What if plan and schedule disagree?
Record the conflict and issue an RFI; do not silently choose one source.
How should alternates be priced?
State the exact changed assumption and affected openings so the comparison remains traceable.
