Quantity Takeoff Services
The detailed measurement of your construction drawings — linear feet, square feet, cubic yards and item counts — measured against the actual scale of your plans, so every quantity you price can be traced back to a sheet, a detail and a note.
What a Quantity Takeoff Is — and Why the Details Matter
A quantity takeoff is the careful measurement of everything a set of construction drawings implies before a single cost is attached: square feet of wall, ceiling and floor, cubic yards of concrete and excavation, linear feet of conduit, piping and trim, and the individual counts of doors, windows, fixtures and mechanical devices. It answers the question "how much is actually there?" before anyone asks "what does it cost?" Those measurements become the common language that connects the drawings to your suppliers, your subcontractors and your final bid number.
Most contractors are rarely short on estimating skill — they are short on hours. A forty-page commercial set can absorb three or four days of careful measurement, and that is time the same estimators need to qualify subcontractors, chase pricing and manage the bid-day logistics that actually win work. When a team is juggling several active bids at once, the takeoff is usually where quality goes first: line items get shortened, areas get assumed from building footprints instead of measured from floor plans, and the errors surface later as change orders or as a bid that quietly funds another contractor's profit margin.
What separates a professional takeoff from a quick measure is traceability. Every quantity should be answerable to a specific sheet, detail and note — not to a recollection of "about what this type of job usually has." That discipline is what lets a general contractor hand a takeoff to a subcontractor and defend it line by line, and what lets a developer roll the same quantities into a budget without re-measuring the project a second time.
- Measured from scaled drawings, not square-foot shortcuts
- One consistent set of rounding and deduct rules across the whole set
- Every line item traceable to a sheet, detail or elevation
- Unit formats matched to how your suppliers and subs actually quote
- Cut, overage and waste left for the pricing stage, where they belong
- Assumptions and notes written on the takeoff — never remembered
What a Takeoff Measures
A professional takeoff is organized by the kind of quantity being measured, then within each kind by assembly and trade. Almost everything on a drawing set falls into four families of measure, and each family has its own conventions for rounding, deducting and reporting. Keeping them separate is what keeps the resulting numbers useful to the estimator who prices them later.
Linear Measurements
Lengths of conduit, pipe, duct, gutters, trim, joists, rebar, edge forms and wall lines. Linear quantities are carried in feet and tenths to match supplier quoting and trade unit rates.
Area Measurements
Square footage of drywall, paint, tile, carpet, roofing, ceilings, formwork and paving. Areas are measured from the actual dimensions on each plan and section, with openings deducted per the stated rule.
Volume Measurements
Cubic yards of concrete for slabs, footings, walls and columns, plus excavation, backfill, structural fill and crushed stone. Volume pricing rewards precision, so volumes are computed from net section sizes, not gross footprints.
Item Counts
Doors, windows, electrical devices, hangers, anchors, fixtures, equipment and any component priced "per each." Counts are taken from schedules and elevations in parallel, so nothing is missed when a door is on the schedule but off the plan.
Within each family the same rule applies everywhere: measure what the drawings actually show, and write down the assumption when the drawing does not show it. A foot of conduit that is measured once and priced once beats a foot that is estimated twice, because estimated line items are where bids quietly gain — or quietly lose — the difference between winning and break-even.
How Professional Takeoffs Read
The value of an outsourced takeoff shows up in three places: the completeness of the measurement, the consistency of the conventions, and the speed with which the numbers reach your estimator. The benchmarks below are the standards CEDS holds every takeoff to.
These are not marketing claims — they are the operating rules of the takeoff desk. The 100% traceability standard means a reviewer can ask where a drywall area came from and get a plan sheet, a room number and a wall line as the answer. The 2x verification means the estimator who receives the takeoff is receiving a checked product, not a first draft that still needs a second set of eyes. When a bid is lost by a half point on margins that nobody expected to attack, it is almost always a measurement gap that started the slide.
The Takeoff Process — Five Disciplined Steps
Every takeoff follows the same sequence, whether it is a two-bedroom remodel or a six-story office building. The sequence is deliberate: the rules are fixed before measurement begins, the measurement follows the rules, and the check happens against both the numbers and the drawings.
Document Review
The full drawing set is read first — architectural, structural, mechanical, electrical and finishes — so the estimator knows what exists before measuring anything. Sheets marked "NTS" (not to scale), missing details and schedule/plan mismatches are logged at this stage, not discovered later.
Quantity Rules Set
Units, rounding conventions, deduction rules and inclusions are fixed before the first measurement. Does a wall count to centerline or face-of-wall? Are window openings deducted from paint everywhere or only above a set width? The rules are written down so the same call is made consistently across every floor.
Measurement
Quantities are measured from the scaled drawings — not from the typical page, but from the actual plan, section and elevation that govern each element. Counts are taken from schedules and drawings in parallel, and the measurement is recorded in the unit format the pricing stage will use.
Double-Check
Every takeoff gets a second pass before release. The first pass checks mathematics and units; the second checks the takeoff against the drawing one more time for scope gaps — a roof beam drawn but not in the schedule, a finishes elevation with no area behind it, a mechanical room nobody defaulted.
Structured Delivery
The takeoff is organized by division and assembly, delivered with the line items, unit reports and the assumption log together. Your estimator receives a measurement they can price immediately — and can re-measure selectively if a question ever comes back from the field.
What You Receive With Every Takeoff
The takeoff is delivered as a package, not a single spreadsheet dump. The point is speed-to-pricing: your estimator should spend time applying rates and judgment, not re-verifying someone else's measurement. Here is exactly what comes back.
- Quantity Summary
- A top-level snapshot of the takeoff by division and assembly — total areas, volumes, lengths and counts — so the scope reads correctly at a glance.
- Line-Item Breakout
- The full detail: every line with its unit, quantity, and the sheet or detail it came from, ready to drop into your estimating software or spreadsheet.
- Unit Reports
- Quantities broken out per floor, per level or per building, so the numbers reconcile against your takeoff takeoffs and your subcontractors' sub-totals.
- Assumption & Exclusion Log
- Every note the takeoff relies on — cut rules, deduct thresholds, "NTS" details, unverifiable items — written down so the pricing stage and the field share the same understanding.
- CSV / XLSX Export
- Machine-readable exports that drop into your estimating platform, takeoff software or buyout spreadsheet without re-keying anything.
- Review Call
- Time to walk through the numbers, challenge any quantity and request refinement before the takeoff goes into the bid.
A Sample Quantity Takeoff Excerpt
Takeoffs read the way pricing needs them to: one line per measurable quantity, in the unit the trade actually quotes. The excerpt below shows how a portion of a mid-size commercial takeoff arrives — note that quantities are exact, units are consistent, and nothing is buried in a note.

Sample figures are illustrative only. Your takeoff is measured from your project's own drawing set, scale and schedules.
Takeoff Conventions That Protect the Bid
Measurement conventions are where takeoffs quietly go wrong, and where an experienced desk earns its keep. The same wall can be measured to the face of the stud or to the centerline of the partition, and both answers are defensible — as long as the answer is consistent and written down. These are the conventions CEDS applies on every set, unless your pricing stage asks for something different.
- Centerline rules applied to shared walls and partitions
- Rounding to whole units at the 0.5 threshold or better
- Openings deducted per written cut rules on every floor
- Elevations measured with note dimensions, not eyeballed
- Schedule and plan checked against each other for counts
- "NTS" details flagged instead of being scaled anyway
- Units confirmed with your pricing stage before release

Takeoff Questions, Answered Straight
Any quantity your pricing stage needs, measured in the unit the trade quotes: linear feet for conduit, piping, duct, trim and lengths of reinforcing; square feet for drywall, paint, flooring, ceilings and roofing; cubic yards for concrete, excavation and fill; and each counts for doors, windows, fixtures, devices and equipment. We confirm the assembly list and unit formats with you before measuring, so the takeoff contains exactly what your bid structure needs — nothing more and nothing missing.
Most residential and mid-size commercial takeoffs land in 48 to 72 hours once the drawing set is complete and the scope is confirmed. Larger sets — multi-story commercial, hospitals, schools — typically run five working days or more. We always confirm the date before starting and schedule the work around your bid deadline rather than asking you to move the bid around ours.
A complete drawing set works in PDF form for most projects — we measure from the scaled sheets directly. CAD files, a specification booklet if one exists, and any scope notes that define inclusions all sharpen the result. If a sheet is marked not-to-scale or a detail is missing, we log it as an assumption rather than guessing. We will always tell you if we need more than you have sent.
A clean, full-scale PDF set is enough for a production-quality takeoff with accurate quantities. CAD files let us confirm lengths and areas mathematically rather than from scale, which is useful on irregular geometry, but we do not need them to deliver a defensible measurement. Send what your drawing set includes; we will work from the best format you have.
A takeoff measures; an estimate prices. The takeoff produces quantities in units — square feet, cubic yards, each — while a construction cost estimate applies labor, material and equipment rates to those quantities to produce dollars. If you already have the numbers, we can price them. If you need both, we deliver the measured takeoff and the priced estimate as one package. See our construction cost estimating page for how the priced version works.
