What do quantity takeoff services include?
Quantity takeoff services measure material quantities from a drawing set and specification book and list them by CSI MasterFormat division, with the unit of measure, measurement rule and a marked-up drawing reference on each line. KNR delivers an Excel workbook and PDF summary; the fee is quoted per project after plan review.
Our Professional Quantity Takeoff Services
A takeoff is only useful if the next person can retrace it. Every line item we produce carries three things: the unit of measure, the measurement rule applied, and the drawing or specification page it came from. Plan reading starts with sheet-by-sheet indexing of the drawing set, so an addendum issued on sheet A-3 is caught before it reaches the takeoff sheet.
We quote the fee per project after reviewing the plans, and we deliver an Excel workbook and PDF summary with marked-up drawing pages. The measurement rules below are the ones we apply on every job, and the same structure carries into the free quantity takeoff excel spreadsheet we use as a starting layout. Clients who outsource construction quantity takeoff services usually want that audit trail most of all, and it is the reason our quantity takeoff services are built around the sheet rather than the total.
Material quantities in purchase units
We measure what gets bought, in purchase units: concrete in cubic yards, framing lumber in linear feet by nominal size, sheathing and drywall in square feet, masonry in units, and fixtures by count each. Waste is stated as a separate line with the typical range noted, so the buyer can see the allowance rather than inherit it. These material quantity takeoff services suit clients who purchase their own materials and need the buy list to match the drawings.
Labor quantities by work task
For labor, the unit changes to the work task: square feet of formwork contact area, linear feet of pipe, each device set, cubic yards placed. Each task links to a quantity that a crew can be priced against, which keeps the takeoff usable for a labor cost estimate rather than a shopping list. If you are building a full labor buildup, our full-scope estimating support carries the takeoff into wage and productivity rates.
Bid package quantities by division
For a bid, the takeoff is organized to match the bid package divisions so the quantities drop straight into the estimate. Residential quantity takeoff services follow the same rule at smaller scale: room-by-room quantities on the floor plan, summarized by CSI MasterFormat division. Send your plans to start the review.
What Is Included in Our Quantity Takeoff Estimates?
Each takeoff opens with a scope statement that names the sheets, the revision log, and any specification section that governs measurement. Scale calibration is recorded per sheet, because a scanned elevation printed at the wrong size produces quantities that look right and are not. Every quantity takeoff services package we issue is traceable back to that statement, and the same discipline carries into our full estimating and takeoff support when the quantities are priced.
Divisions, assemblies and work items
The takeoff is organized by CSI MasterFormat division and broken into assemblies and work items within each division. A wall assembly, for example, splits into studs, plates, sheathing, insulation, and finishes, each with its own unit. The bid package index tells you which division each line item belongs to, which keeps bid leveling between trades on the same basis.
Quantities, units and measurement rules
Quantities are reported in the unit the trade buys or installs: square feet of slab area, cubic yards of concrete, linear feet of pipe, tons of rebar, count each for doors and fixtures. The measurement rule sits beside each line, so a reviewer can check whether openings were deducted or formwork was measured to contact area. A material takeoff without its rule is only half a document.
Materials, labor, equipment and cost breakdowns
Each line item carries separate material, labor, and equipment quantities so the estimate can be built without re-measuring. The breakdown includes:
- Material quantity in purchase units, with waste shown as its own line
- Labor quantity in the task unit, ready for a productivity rate
- Equipment quantity where the task requires it, such as crane time or pump hours
- Cost buildup columns left blank for your rates or filled from published wage and price data
When the takeoff feeds a full construction estimate, the cost columns are completed and reviewed by an estimator, and the resulting quantities-only workbook is one of the deliverables our quantity takeoff services clients receive alongside the PDF summary.
Who Needs Our Quantity Takeoff Services?
A quantity takeoff company is judged on whether the client can defend the numbers in a bid leveling meeting. Our takeoff sheet names the sheet, the detail, and the rule behind every figure, so a reviewer can challenge a line and get an answer. The drawing set is indexed before measurement begins, and the scope of work is reconciled against the takeoff divisions at handoff. Clients order quantity takeoff services when they need measured quantities they can audit line by line, not a lump figure.
Specialty subcontractors
Trade subcontractors use the takeoff to price their own scope without measuring the whole building. A framing contractor gets studs, plates, headers, and sheathing by floor; a mechanical contractor gets pipe and fittings by system. The quantities map to their bid form, not to the general contractor's summary.
General contractors and home builders
General contractors use the takeoff to check subcontractor bids and to build the bid leveling sheet. Home builders use it to order materials by house plan and to compare plan revisions before release. Our quantity takeoff services for general contractors keep the divisions aligned with the bid package.
Developers, architects and suppliers
Developers need order-of-magnitude quantities for pro forma checks, architects need them for cost feedback during design, and suppliers need them for quoting. Each group gets the same traceable sheet with units and rules visible, so the numbers can be compared across revisions.
Types of Quantity Takeoff Projects We Estimate
The unit of measure rarely changes between project types; the drawing conventions do. A quantity takeoff agency working across sectors has to read a residential floor plan, a commercial reflected ceiling plan, and a civil site plan with different habits. We state which convention applies at the top of each takeoff, so a reviewer can check the measurement rule before checking the arithmetic. Our quantity takeoff services cover all three sectors, and each line item carries its unit, its source sheet, and the rule used to measure it. A worked quantity takeoff example shows how those three fields sit together on a finished sheet.
Residential projects
Residential takeoffs work room by room from the floor plan, with framing measured by wall length and height and finishes measured net of openings. Subdivision work repeats the same house plan across lots, so quantities are built once and multiplied by lot count, with site-specific variations called out. See our construction takeoff services for the broader scope.
Commercial buildings
Commercial buildings add curtain wall, mechanical systems, and tenant fit-out scopes that require section details and schedules, not just plans. The general contractor usually needs quantities split by bid package, which means the takeoff must follow the specification section order. Commercial site quantity takeoff services stop at the building line; earthwork and paving quantities are handled as a separate scope.
Industrial and infrastructure projects
Industrial and infrastructure work shifts the emphasis to earthwork, structural steel, and process piping, where quantities are driven by sections and profiles rather than floor plans. Our quantity takeoff and estimating work for these projects follows the same traceable format.
Our Quantity Takeoff Estimating Process
Every takeoff follows the same sequence so that a reviewer can retrace any number back to a sheet and a rule. If you are new to the deliverable, start with what is quantity takeoff in construction before sending drawings. You can use our construction takeoff services as a standalone scope or fold the quantities into a full construction estimate. When you outsource construction quantity takeoff services to us, the drawing set and specifications you send become the only source of quantities; nothing is carried over from a prior issue unless the revision log says it still applies.
Submit drawings and specifications
Send the complete bid package: architectural, structural, civil, MEP, the specification book and every addendum issued to date. We log each file by sheet number and revision date, then confirm which issue is the basis of the takeoff. Missing sheets or an unnumbered addendum are flagged before work starts, because a quantity keyed to a superseded plan is worse than no quantity at all.
Plan review and digital takeoff
The estimator reads floor plans, elevations, sections and schedules together, then calibrates the digital scale against a stated dimension on each sheet. Each line item carries a measurement rule — net area in square feet for floor finishes, centerline linear feet for pipe and conduit, count each for fixtures and doors — written next to the quantity. Where a subcontractor will install the work, the takeoff stays inside that trade's scope boundary so the number can be compared line for line.
Cost calculation, quality checks and delivery
Quantities are priced, then a second pass re-measures a sample of high-value lines against the drawings and checks unit consistency across the workbook. We return an Excel workbook, a PDF summary and marked-up drawing pages showing where each quantity was measured. Assumptions, exclusions and open questions sit on their own tab so you can resolve them before the number goes to a client, and the same review step applies to every set of quantity takeoff services we produce.
Sample Quantity Takeoff Estimate and Deliverables
The worked example below is illustrative and uses round assumptions, not a quoted fee or a market price. Assumptions: a single-story commercial tenant fit-out of 4,000 square feet on a slab-on-grade; 9-foot finished ceiling height; 2-inch by 4-inch metal stud partitions at 16 inches on center with one layer of 5/8-inch gypsum board each side; 100 linear feet of partition height deducted for openings; 10 percent waste on board and studs; three paint coats on both faces. Board area = 4,000 square feet of floor area served by partitions, taken as 1,150 square feet of wall face per side, less 100 square feet of openings, times two faces = 2,100 square feet, plus 10 percent waste = 2,310 square feet. Studs = 2,100 square feet of wall face ÷ 1.333 square feet per stud ≈ 1,575 studs, plus 10 percent = 1,733 studs. Track = 2 × 115 linear feet of partition = 230 linear feet, plus 10 percent = 253 linear feet. Paint = 2,100 square feet × 3 coats = 6,300 square feet. Every extension in the table follows that arithmetic, and a commercial site quantity takeoff services scope would apply the same method to site-wide areas read from the civil sheets.
| Line item | Quantity | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| 5/8-inch gypsum board, one layer each side | 2,310 | square feet | $1.85 – $2.40 | $4,273.50 – $5,544.00 |
| 2-1/2-inch metal studs at 16 inches on center | 1,733 | each | $3.10 – $3.90 | $5,372.30 – $6,758.70 |
| Metal track, floor and ceiling | 253 | linear feet | $2.20 – $2.75 | $556.60 – $695.75 |
| Joint compound, tape and fasteners | 2,310 | square feet | $0.55 – $0.75 | $1,270.50 – $1,732.50 |
| Interior latex paint, three coats | 6,300 | square feet | $0.95 – $1.35 | $5,985.00 – $8,505.00 |
| Total | — | — | — | $17,457.90 – $23,235.95 |
Excel quantity takeoff sheet
The workbook holds one row per line item with the CSI MasterFormat division, the sheet reference, the measurement rule, the raw quantity, the waste factor and the adjusted quantity. Formulas stay live so you can change a waste percentage and watch the total move. A revision tab records which addendum each row was measured against.
Marked-up drawings
Each PDF page is color-coded by trade with dimension strings and count bubbles placed where the quantity was taken. Where a number comes from a section detail or a schedule rather than a plan view, the detail is cropped onto the same markup. The estimator initials each page so a reviewer knows who to ask.
Itemized cost estimate
Pricing is applied to the adjusted quantities, with labor and material shown separately and the source of each rate noted. The cost estimate carries an assumptions page listing what was excluded, such as firestopping or temporary protection. Use it as the quantity backbone of a worked construction estimate example or hand it to a trade for pricing.
Software and Pricing Data We Use
Quantities and prices are kept in separate layers so a quantity can be re-priced without re-measuring the drawings. That separation matters on quantity takeoff services for subdivisions, where the same house plan repeats across lots and only the site conditions and location factors change. The chart below tracks the Producer Price Index for the materials in this scope, rebased to 100, so you can see how input costs have moved over the period shown.
Takeoff and estimating software
We work in three tool categories: on-screen PDF takeoff for scaling and marking up drawings, spreadsheet estimating for the line-item workbook and its formulas, and subscription cost databases for material and labor rates. Quantities are keyed from the calibrated drawing, never typed from a printed schedule without a cross-check. If you already run construction quantity takeoff software in house, we can match your line-item structure so the files merge cleanly.
Regional material and labor pricing method
Rates start from national average unit costs, adjusted with published U.S. Bureau of Labor Statistics wage data and the Producer Price Index series shown in the chart below, then reviewed by an estimator for location, prevailing wage and project conditions. The wage table below lists the trade classifications behind the labor portion. Material indexes move at different speeds — lumber, ready-mix concrete, steel mill products and copper wire and cable each follow their own curve — so a takeoff that carries a single escalation rate will drift. Rates are restated at the date stated on the summary, and the schedule of values is built so bid leveling compares like scopes.

Why Contractors Choose Our Estimating Services
The reason is method, not marketing: each number on the sheet can be traced to a drawing, a measurement rule and a rate source. General contractors use the output for bid leveling across trades; trade contractors use it to confirm that the square feet in their scope match the drawings before they commit. Where a model exists, quantities can also be pulled from it as quantity takeoff in Revit and reconciled line by line against the 2D sheets.
Trade-specific expertise
Material quantity takeoff services are organized by CSI MasterFormat division, so concrete, framing, envelope, finishes and MEP quantities land in separate sections with their own units. A line measured from a specification section is cited to that section, and a substituted product is flagged rather than silently swapped.
Quality control and clear assumptions
Every drawing issue is logged, and each addendum is checked against the quantities already taken to see what changed. Assumptions and exclusions are written on the summary page, not buried in a cell comment. If a dimension is illegible or a detail is missing, we ask rather than guess and mark the line as pending.
Turnaround, communication and revisions
Delivery dates are agreed when we review the plans and confirm scope, and the date is written on the proposal. Revisions against a later addendum or a revised sheet are handled as a defined scope with its own log entry, so you can see exactly which quantities moved. Questions go to the estimator who measured the line, and you can send your plans to start that review.
Quantity Takeoff Services Pricing
The fee for our quantity takeoff services is quoted per project after we review the drawing set. We do not publish a rate per sheet or a price per square foot, because two 30-sheet sets can carry very different work: one may hold a single architectural plan and a finish schedule, the other full structural, mechanical and electrical packages with alternates and three addenda. Send the plans through our request a quote page and the quote states the scope, the divisions covered and the deliverables included.
The calculator below handles one line item at a time: you enter slab length, width, thickness and a waste percentage, and it returns the area, the cubic feet, the net cubic yards and the order quantity. That is the same arithmetic our estimators run on a slab line, and it shows why the unit of measure and the waste factor belong on the takeoff sheet rather than in someone's head. The rest of the sheet — walls, framing, finishes — is built the same way, line by line, with the measurement rule written next to each result.
How quotes are calculated
We price the work from the sheets, not from a menu. The estimator counts the drawing sheets by discipline, notes which CSI MasterFormat divisions the scope touches, and marks the schedules and section details that need a closer read. Alternates, unit-price items and addenda each add review time, so they are listed in the quote rather than absorbed into a lump sum. A set with a clear revision log and a single stamped issue is quicker to take off than a set with superseded sheets mixed in, and the quote reflects that difference.
What affects price and delivery time
Four things move the number: sheet count and drawing scale, the number of trades and divisions in scope, the condition of the set, and the level of detail you ask for. A scope for general contractors that covers all divisions for a bid package takes longer than a single-trade count, and a commercial site with earthwork measured in cubic yards takes longer again. We confirm the scope in writing before starting, and the quote states what is included and what is not.

Formula: length × width × (thickness ÷ 12) ÷ 27 = cubic yards. Thickened edges, footings and pump waste are taken off separately.
Quantity Takeoff Services Across the US
We produce quantity takeoff services for clients in all 50 states from one team, so the method does not change with the ZIP code. What changes is the cost that sits on top of the quantities: wage levels differ by market, public work may carry prevailing wage requirements, and material delivery distances affect what a supplier quotes. Those are pricing inputs; the count each, linear feet and square feet on the takeoff sheet stay the same.
Climate and code adoption also shift scope between regions. A cold-climate set may show deeper footings and more insulation, a coastal set may carry wind-load detailing, and local amendments to the IBC or IRC can add or remove line items. We take off what the drawings and specifications show, cite the division for each line, and return marked-up drawings so your estimator can see where every number came from. Confirm the code edition in force with the local building department before pricing.
Frequently Asked Questions
How much does a quantity takeoff estimate cost?
The fee is quoted per project after we review the plans. It depends on the number of sheets, how many trades the takeoff covers, the drawing quality, and whether you supply a template or a division-by-division breakdown. Send the drawing set and specification sections, and the quote states the scope and the fee before any work starts.
How long does a quantity takeoff takeoff take?
The delivery date is set when we quote, after we count the sheets and check the drawing set for missing plans or details. Addenda and revised sheets restart the clock on the affected pages, so send them as they are issued. We confirm the date in writing with the quote rather than quoting a standard turnaround.
Do you estimate labor and material costs?
This service delivers quantities only: counts, linear feet, square feet, and cubic yards by line item, with no pricing. If you need labor and material costs on the same scope, ask for the priced estimate so the takeoff feeds a cost sheet built from published wage and price data. Keeping the two steps separate lets you apply your own rates to the quantities.
What drawings do you need?
Send the complete drawing set: floor plans, elevations, sections, schedule sheets, and the specification sections that name products and units. Include the revision log and every addendum issued to date. A partial set produces a partial takeoff, so tell us which sheets are still pending before we start the plan reading.
Can you use my estimate template?
Send the template with the plans, and we confirm whether the estimate can be delivered in it. We match your line item order, division headings, and unit of measure columns where the template supports them. If a field cannot be populated from the drawings, we say so in the quote rather than leaving a blank column.
Do you sign NDAs?
Clients can request a confidentiality agreement before sending drawings, and the terms are agreed before plan review begins. Tell us at first contact so the paperwork is signed before any files transfer. We do not publish a standard NDA policy, so the terms are set per client.
Do you provide quantity takeoff services for residential projects?
Yes. Residential quantity takeoff services cover single-family and multifamily plans: framing counts by member size, sheathing and drywall square footage, concrete cubic yards for footings and slabs, and finish quantities by room. We read the floor plans, elevations, and window and door schedules, and we note where a plan is silent on a detail.
How do you handle waste factors in the quantities?
Waste is shown as a separate line item, not folded into the net quantity. We state the typical waste percentage applied to each material, such as framing lumber or finish flooring, so you can change it without redoing the arithmetic. The takeoff sheet shows the net quantity, the waste allowance, and the total.
What unit of measure do you use for each line item?
Each line carries the unit that matches how the trade buys the material: square feet for drywall and roofing, linear feet for pipe and trim, cubic yards for concrete and earthwork, and count each for fixtures and doors. The measurement rule behind each number is written next to the line item so another estimator can check it.
Can you break the takeoff out by bid package?
Yes. We organize line items by CSI MasterFormat division and can regroup them to match your bid packages, so a subcontractor receives only the scope they are pricing. Send the bid package list with the plans, and the takeoff sheet follows that order for bid leveling across bidders.
How do you handle addenda and revised drawings?
We keep a revision log and mark each takeoff line with the sheet and revision it came from. When an addendum changes a detail, we re-measure the affected line items and list the changed quantities separately so you can see what moved. The marked-up drawing pages show where each revision was applied.
What do I receive at the end of the takeoff?
You receive an Excel workbook with the line items, units, measurement rules, and waste allowances, a PDF summary, and marked-up drawing pages showing what was measured. The workbook is built so you can filter by division or bid package. Nothing in the deliverable is priced, since this service covers quantities only.
Can you take off a commercial site package as well as the building?
Commercial site quantity takeoff services cover the building scope, and sitework quantities such as excavation, paving, and utilities are handled as a separate civil takeoff. Tell us at the quote stage which site sheets are in scope, because the measurement rules and units differ from the building trades.
How do you check the takeoff before it is delivered?
A second estimator reviews the sheet against the drawing set: scale calibration on each plan sheet, cross-checks between schedules and plans, and a comparison of totals against the expected range for the building type. Discrepancies are resolved before delivery, and the marked-up drawings show the measured areas.
