What do quantity surveyor services include?
Quantity surveyor services measure quantities from your drawings and specifications, apply a stated measurement rule and waste factor, then price each line item with unit costs, labor rates and production rates. The output is a bill of quantities with a cost breakdown you can check against the drawings.
Our Professional Quantity Surveyor Services
A quantity surveyor measures the drawing the way a contractor will build it, then prices what was measured. We produce that measurement as a line-item takeoff keyed to CSI MasterFormat divisions, with the unit of measure, the measurement rule and the arithmetic visible on every row. The workbook and PDF summary come back with marked-up drawing pages, so you can trace any figure to the sheet it came from. Our quantity surveyor services are priced per project after we review the plans, and every rate is a national average adjusted with published U.S. wage and price data and then reviewed by an estimator. The same measurement supports a conceptual estimate at schematic stage or a full bill of quantities at construction documents, and it pairs with our quantity takeoff support when you need the measurement alone.
Material quantities by trade unit
Materials are measured by the unit each trade buys them in: square feet of drywall board, linear feet of stud framing and conduit, cubic yards of ready-mix, tons of rebar. Each line carries a waste factor stated as typical for the assembly, so a 1,200 square foot ceiling at 10 percent waste shows 1,320 square feet rather than a rounded allowance. Fixture counts and door and window schedules are reconciled against the plan sheets before the quantities close. You get a material quantity schedule by division with the measurement rule noted on each row.
Labor hours from production rates
Labor is priced from production rates rather than a percentage of material. We state the crew composition, the output assumed per hour and the resulting labor hours per line item, then apply a wage from published U.S. Bureau of Labor Statistics data for the trade involved. A concrete slab line, for example, separates placement labor from finishing labor because the wage for cement masons and concrete finishers differs from that of general laborers. Supervisory time is carried as its own line so you can see what it adds. The result is a labor cost estimate you can compare against your own crew's historical output.
Bid package cost breakdown
At bid stage the takeoff is organized to mirror the bid package: alternates and allowances sit on separate lines, and scope of work notes flag what is excluded. Each division subtotal rolls into a summary page with the unit price, extended quantity and extended cost shown side by side. The PDF summary is formatted so an estimator can check a line in seconds, and the Excel workbook stays live if you want to substitute your own material pricing. For a fuller priced package, see our construction estimating services.
What Is Included in Our Quantity Surveyor Estimates?
Construction quantity surveying starts with a drawing review, not a spreadsheet. We read the general notes, the schedule sheets and the typical details first, because that is where the measurement rules for a project usually live. Each quantity is then entered as a line item with its unit of measure, its source sheet and the calculation behind it. The estimate class follows the documents: a conceptual estimate from schematic design carries ranges and larger contingency, while a takeoff from construction documents carries measured quantities and unit prices. Our quantity surveyor services follow that same sequence on every package, so a reviewer can trace any total back to a sheet and a rule, and the output feeds directly into construction cost estimating services when the numbers move to a bid form.
Divisions 02 through 16 work items and general conditions
The takeoff covers the work items a contractor prices, organized by CSI MasterFormat division: sitework and demolition in Division 02 and 31, concrete in Division 03, masonry in 04, metals in 05, wood and plastics in 06, thermal and moisture protection in 07, openings in 08, finishes in 09, specialties in 10, equipment in 11, furnishings in 12, special construction in 13, conveying systems in 14, mechanical in 21 through 23, electrical in 26, and communications and electronic safety in 27 and 28. General conditions and temporary facilities are listed separately so they are not buried in a trade line. We confirm the division structure with you at kickoff if your bid form uses a different breakdown.
Square feet, linear feet, cubic yards and fixture counts
Quantities are reported in the unit the trade actually buys and installs, and the measurement rule is written beside each one. Common examples:
- Concrete: cubic yards of volume, plus square feet of formwork contact area and tons of rebar
- Drywall: square feet of board, linear feet of corner bead and track, and stud count by spacing
- Framing: board feet or linear feet by member size, with headers and blocking counted separately
- Electrical: linear feet of conduit by size, plus fixture and device counts from the schedule
- Finishes: square feet of floor and wall area, with openings deducted per the stated rule
- Sitework: cubic yards of cut and fill, square feet of paving, linear feet of curb and pipe
Where a plan dimension is missing or ambiguous, the row is flagged rather than filled with an assumption.
Materials, labor, equipment and cost breakdowns
Each line is split so you can see what drives the number. The cost breakdown shows:
- Material quantity and unit price, with the price basis noted
- Labor hours, crew makeup and the wage applied from published BLS data
- Equipment, either as a rental line or as a rate per labor hour
- Waste factor and the assembly it applies to
- Subtotal by division, then contingency and markups on separate lines
Material pricing is tracked against published Producer Price Index movement for the relevant commodity, so lumber, ready-mix, steel and copper items carry a current basis rather than a stale quote. The workbook opens in Excel for quantity takeoff review, and the PDF summary carries the marked-up drawings.
Who Needs Our Quantity Surveyor Services?
Different readers use the same measurement for different decisions. A subcontractor needs the quantity by line item to set a bid, while an owner needs the division subtotals to test a budget. Our quantity surveyor services are built so both can work from one workbook without re-keying anything. Bill of quantities preparation follows the format your bid form asks for, and every figure traces back to a sheet number.
Specialty subcontractors
Trade contractors use the takeoff to check their own quantity before a bid closes, and to spot scope they may have missed. A concrete subcontractor wants formwork contact area and rebar tonnage separated from the slab volume; an electrical subcontractor wants conduit linear feet and fixture counts by schedule. Because each row shows the measurement rule, a subcontractor can compare our quantity against their field measurement and see exactly where the difference sits.
General contractors and home builders
General contractors use the division subtotals to build a bid package and to check sub quotes for gaps. Home builders use the same quantity takeoff to order framing lumber, sheathing and drywall by phase. When a sub quote comes in well below our line, the marked-up drawing shows which area was likely missed. For the priced version of the same scope, see our construction cost estimating services.
Developers, architects and suppliers
Developers test a pro forma against division subtotals before committing to a design. Architects use the quantities to compare alternates at construction documents stage without waiting for a contractor's bid. Suppliers and material vendors use the schedule to plan deliveries and to quote against a known quantity rather than a square-foot allowance.
Types of Quantity Surveyor Projects We Estimate
The measurement method does not change with building type, but the scope, the unit of measure emphasis and the contingency do. A quantity surveyor working from a residential plan set spends most of the effort on framing and finishes; an industrial package turns on structural steel tonnage and process piping. We confirm the project type and the estimate class before starting, because that decides how much contingency sits on the summary page. Our quantity surveyor services for each type are delivered in the same workbook and PDF format, with labor priced through our labor cost estimating services so wages and production rates stay visible on every line.
Residential projects
Single-family and multifamily work is measured from floor plans, elevations and framing plans, with wall area net of openings and roof area by slope. Waste factors run higher on cut-heavy items such as siding and flooring, and we state the factor used on each line. Repeated unit types are measured once and multiplied, with the count shown.
Commercial buildings
Office, retail and institutional projects bring larger mechanical, electrical and fire protection scope, so fixture counts, conduit linear feet and sprinkler head counts come straight from the schedules. Tenant improvements are separated from base building work so a landlord and tenant can split the cost. Alternates and allowances are listed as their own lines for the bid package.
Industrial and infrastructure projects
Structural steel tonnage, concrete volume, process piping linear feet and sitework cubic yards dominate these estimates, and the commodity exposure is larger. Steel and copper items are priced against current published index movement, and the summary notes which lines carry that basis. For early-stage work, our preliminary and conceptual estimating fits the same quantity framework to a schematic design, and the same quantity surveyor services carry through to construction documents.
Our Quantity Surveyor Estimating Process
A quantity surveyor cost estimate is only as good as the measurement trail behind it. Our quantity surveyor services follow a fixed sequence: receive the documents, measure the scope, price the quantities, then check both before anything leaves the office. Each step produces a record you can audit against the drawings.
We do not open a takeoff until we know which drawing set is current. Send the full package and tell us about addenda, alternates and any scope you are holding out of the number.
Submit drawings and specifications
Send architectural, structural, mechanical, electrical and plumbing drawings at the latest revision, plus the project manual and any addenda. We log the set, the sheet count and the date received so the estimate is tied to one document issue. If a sheet is missing or superseded, we flag it before measuring rather than assuming a detail.
The scope of work comes from the specifications as much as the plans: wall types, finish schedules, equipment schedules and division 01 requirements all change quantities. If you are comparing our number with a bid estimate, tell us which alternates and allowances must appear.
Plan review and digital takeoff
A cost estimator reviews each sheet for scale, dimensions and cross-references, then measures on screen using PDF takeoff tools with the sheet scale set per view. Every quantity carries a measurement rule: net wall area for drywall, centerline length for pipe, count for fixtures, and formwork contact area rather than slab volume. Where a drawing dimension and a scale measurement disagree, the written dimension governs and we note the conflict.
Quantities are grouped by CSI MasterFormat division and by trade so the same line can be priced and later checked against a subcontractor quote.
Cost calculation, quality checks and delivery
Pricing is applied line by line, then the workbook is checked twice: once for arithmetic and once against the drawing set for missed scope. We test totals, confirm units match between takeoff and pricing, and verify that waste and contingency are applied once, not twice. The finished package is an Excel workbook, a PDF summary and marked-up drawing pages showing what was measured.
You receive the assumptions in writing, so a reviewer can trace any line from the summary back to a marked-up sheet, and the same quantities can feed budget estimates at the next design stage. To start, send your plans with the project location and the estimate class you need.
Sample Quantity Surveyor Estimate and Deliverables
The example below is illustrative only. It shows how quantity surveyor services output is structured, not a price for any real project. Assumptions: a single-story commercial tenant fit-out of 4,000 square feet, 9-foot ceiling, 2x4 stud framing at 16 inches on center, one layer of 5/8-inch gypsum board each side of interior partitions, and 1,200 square feet of partition area. A 10 percent waste factor is applied to board and studs, typical for cut-and-fit work.
Material pricing is taken from current supplier quotes or a cost database and adjusted for the project ZIP code. Labor is priced from the wage table and productivity assumptions described in the next section. Alternates are listed separately so the base bid stays comparable. The table below shows the arithmetic for the partition line items only, at the quantities stated above.
| Line item | Measurement rule | Net quantity | Waste factor | Priced quantity | Unit |
|---|---|---|---|---|---|
| 5/8-inch gypsum board, partitions | 1,200 sf of partition face, one layer each side | 2,400 sf | 10% | 2,640 sf | square feet |
| 2x4 studs at 16 inches on center | 1,200 sf ÷ 9 ft height = 133 lf of wall; 0.75 studs per lf plus track | 100 studs; 266 lf track | 10% | 110 studs; 293 lf track | each / linear feet |
| Joint compound and tape | 1.0 lb compound and 1.0 lf tape per sf of board | 2,400 lb; 2,400 lf | 10% | 2,640 lb; 2,640 lf | pounds / linear feet |
| Drywall screws | 32 screws per 4x8 sheet; 2,400 sf ÷ 32 sf = 75 sheets | 2,400 screws | 10% | 2,640 screws | each |
Excel quantity takeoff sheet
The workbook holds one tab per division, with columns for description, quantity, unit of measure, measurement rule, waste factor and source sheet number. Formulas stay live so you can change a quantity and see the extended cost update. This is the quantity takeoff Excel file your estimator or subcontractor can check line by line without re-measuring.
Marked-up drawings
Each measured sheet is returned with color-coded highlights, dimension strings and quantity tags keyed to the workbook line numbers. Rooms, wall types and fixture counts are labeled so a reviewer can confirm that 1,200 square feet of partition really is 1,200 square feet. Areas we excluded are marked as excluded, which matters as much as what we measured.
Itemized cost estimate
The PDF summary rolls the takeoff into a cost breakdown by division, separating material, labor and equipment. Alternates and allowances sit on their own lines, and the basis for each unit price is stated. Any line you disagree with can be traced back to the sheet and the measurement rule behind it.
Software and Pricing Data We Use
A boq takeoff is a measurement exercise first and a pricing exercise second. The tools matter less than the discipline of recording a unit of measure and a rule for every line, whether the quantity is linear feet of conduit, square feet of formwork or a fixture count.
Takeoff and estimating software
We measure on screen from PDF drawing sets using on-screen takeoff tools with per-sheet scale calibration, dimension strings and quantity markup that exports to a spreadsheet. Pricing runs in spreadsheet estimating workbooks with live formulas, so a change in a quantity flows through to the extended cost. Unit costs come from construction cost databases and current supplier quotes, and assemblies are built from published labor and material components rather than typed in from memory.
Every line keeps its source: sheet number, measurement rule and unit. That trail is what lets a second estimator reproduce the number.
Regional material and labor pricing method
Base costs are national averages, then adjusted for the project's location, prevailing wage requirements and conditions such as occupied space, height or phased work. Labor rate is built from the wage table below plus burden, and production rate assumptions are stated per line. Material pricing is adjusted using the Producer Price Index series shown in the chart below, rebased to 100 so you can see how lumber, ready-mix concrete, steel mill products and copper wire and cable have moved over the period.
An allowance is used only where the design does not yet fix a quantity, and it is labeled as an allowance rather than buried in a unit price. For early-stage work, preliminary and conceptual estimates set the assumptions before drawings are complete.
Material price movement, Oct 2023 to Sep 2026
| Occupation | 25th percentile | Median | 75th percentile |
|---|---|---|---|
| Construction laborers | $18.57 | $22.66 | $28.72 |
| Carpenters | $23.32 | $29.12 | $36.94 |
| Electricians | $23.76 | $30.38 | $40.36 |
| Plumbers, pipefitters and steamfitters | $24.13 | $30.67 | $40.92 |
| Cement masons and concrete finishers | $22.60 | $27.41 | $32.15 |
| First-line supervisors, construction trades | $30.48 | $38.42 | $48.78 |
| Cost estimators | $29.40 | $37.86 | $48.97 |

Why Contractors Choose Our Estimating Services
The value of a takeoff is not the total at the bottom; it is whether someone else can retrace it. Our sheets carry the unit, the measurement rule and the arithmetic for each line, so a reviewer can audit a quantity in square feet back to the sheet it came from.
Trade-specific expertise
A concrete line is measured differently from a drywall line: cubic yards for slab concrete, contact area for formwork, weight for rebar, and square feet of board with a stated waste factor for partitions. We apply the measurement rule that matches the trade, then price with a production rate that reflects the actual assembly. The quantity takeoff Excel output keeps those units intact, so a unit price is never applied to the wrong unit.
Quality control and clear assumptions
Before delivery, a second pass checks arithmetic, unit consistency and drawing coverage. Assumptions are written on the face of the estimate: what was included, what was excluded, which addenda were used and where an allowance stands in for a missing detail. If a line depends on a design decision that is still open, we say so rather than pricing it silently.
Turnaround, communication and revisions
Delivery dates are agreed when we review the plans, based on sheet count, scope and the estimate class you need, and we confirm the date in writing before starting. Questions during the takeoff go back to you rather than becoming an assumption. If drawings are revised, we reissue the affected tabs and mark what changed, so you can see the delta against the previous issue.
For a full package across all divisions, see our division-by-division estimating package, or request a quote with your drawing set. When the schedule compresses and pricing must land on bid day, our hard bid and bid day support keeps the takeoff and the bid form in step.
Quantity Surveyor Services Pricing
The fee for our quantity surveyor services is quoted per project after an estimator has reviewed the drawing set. We do not publish a rate card, because the same 20,000 sq ft building can carry 40 sheets or 140, and the sheet count drives the work more than the floor area does. Send the plans, the spec book and any addenda through our request a quote page and the quote comes back with the scope of sheets and trades it covers.
Where a client needs a number before pricing is firm, we work from a unit-price basis and flag it as such: concrete priced at a rate per cubic yard of placed volume, rebar at a rate per ton by bar size, formwork at a rate per square foot of contact area. Those are the same measurement rules a later detailed takeoff will follow, so the early figure reconciles with the final one instead of being replaced by it.
How quotes are calculated
A quote is built from the scope of the drawing set, not from a square-foot rate. The estimator records how many architectural, structural, mechanical, electrical and plumbing sheets are in the package, which CSI MasterFormat divisions are in scope, how many alternates and allowances the bid form requires, and whether the documents are at schematic design or full construction documents.
Each line item is then counted with a stated unit of measure and a stated measurement rule, priced, and extended. The total is the sum of the extended line items plus a contingency line if you ask for one, and the quote reflects that volume of counting. A package with 60 sheets across 12 divisions takes more review than a 12-sheet interior fit-out, and the fee follows that difference rather than the contract value.
What affects price and delivery time
Four things move the fee most: sheet count, the number of trades in scope, the number of alternates and addenda, and how legible the documents are. A set with dimensioned floor plans and a written spec prices faster than one where the estimator has to scale every wall from a PDF. Addenda issued after the first review are re-counted against the affected sheets, and that re-count is part of the quote, not a surprise.
Delivery time runs on the same drivers. A single-trade package with a clean plan set moves through faster than a full-division package with mechanical and electrical drawings, and a fixed bid date tightens the schedule because the work is sequenced to land before submission. We confirm the delivery date in writing with the quote, and the estimator tells you which sheets are driving it. The calculator below converts your own area and cost inputs into a budget total; it carries no prices of its own and does not change the fee for the takeoff.

Quantity Surveyor Services Across the US
One team handles material quantity takeoffs for projects in all 50 states, and the same line-item structure is used regardless of where the site sits. What changes by region is the input, not the method. Wage levels differ by metro area, and public work under a prevailing wage determination carries rates that a private commercial job in the same county does not. Our cost estimating work applies published wage data by trade and adjusts it to the project location before the labor line is extended.
Material delivery is the second regional variable. Ready-mix concrete, structural steel and lumber carry different freight and availability profiles depending on distance from the nearest plant or mill, and a remote site can add a delivery premium that a metro site does not see. Climate and code adoption are the third: frost depth changes footing and formwork quantities, seismic and wind provisions change connection detailing and anchor counts, and each state adopts its own edition of the IBC and the NEC. Confirm the adopted edition with the local building department before the cost breakdown is finalized.
The estimate class sets how much of that detail is visible. A Class 4 or Class 5 conceptual estimate from schematic design works in assembly-level quantities and a wider contingency, while a Class 2 or Class 1 estimate from construction documents counts individual fixtures, runs of conduit in linear feet and cubic yards of concrete. The AACE estimate class is stated on the summary page so a reader knows how firm each number is.
Frequently Asked Questions
How much does a quantity surveyor estimate cost?
The fee is quoted per project after we review the plans. It depends on drawing count and sheet size, the number of CSI MasterFormat divisions in scope, whether the takeoff is a single trade or a full bill of quantities, the level of detail in the cost breakdown, and whether you supply a template to fill. Send the plan set and the scope you need priced, and the quote states the fee against that scope.
How long does a quantity surveyor takeoff take?
The delivery date is set when we quote, after we have seen the drawings and the scope. It moves with sheet count, the number of divisions, how legible the dimensions are, and how many alternates or allowances you want carried separately. We confirm the date in the quote rather than promising it before plan review, and you get it in writing before work starts.
Do you estimate labor and material costs?
Yes. Each line item carries a quantity from the takeoff, a unit of measure, a material unit price, and a labor component built from a production rate and a published wage rate for the trade. Supervisors, contingency, and sales tax where applicable are shown as separate lines, so you can see which part of the number is material and which is labor.
What drawings do you need?
Send the construction documents: architectural, structural, mechanical, electrical, and plumbing sheets, plus the specifications and any addenda. For a conceptual or schematic-design estimate, floor plans with overall dimensions and a written scope of work are enough to start. A civil or site plan helps when earthwork and utilities are in scope. PDF is fine; native files help when dimensions are missing.
Can you use my estimate template?
Send the template with the plans and we confirm whether the estimate can be delivered in it. We work in Excel workbooks and PDF summaries as standard, so a spreadsheet template with your own division structure, line item codes, and summary tabs is usually straightforward. If the template needs formulas or a structure we cannot reproduce, we say so before the work begins.
Do you sign NDAs?
Clients can request one before sending drawings, and the terms are agreed before plan review starts. Send the document you want signed along with a note on who is authorized to sign it, and we confirm before any files are transferred. We do not publish a standard NDA policy, so the terms are handled per project.
What is a bill of quantities, and how does it differ from a takeoff?
A takeoff measures quantities from the drawings; a bill of quantities organizes those quantities into priced line items by CSI MasterFormat division, with units, rates, and extensions. The BOQ is the priced document a cost estimator or contractor prices against, and it usually carries preliminaries, contingency, and alternates as separate sections. We can deliver either, or both, from the same measurement pass.
Which units of measure do you use?
Square feet for slab, drywall, roofing, and floor finishes; cubic yards for concrete and earthwork; linear feet for conduit, pipe, rebar, and framing members; each for fixtures, doors, and equipment. Counts are shown with the fixture schedule reference. The unit and the measurement rule are printed on every line so a reviewer can re-measure the same way.
How do you handle waste factors and allowances?
Waste is applied as a stated percentage on the measured quantity, not folded silently into the unit price, so you can see the gross quantity and the net. Typical waste ranges differ by material: tile and hardwood run higher than structural concrete or rebar. Allowances are carried as separate line items with a stated basis, and they are flagged for reconciliation once selections are made.
Can you price alternates and separate bid packages?
Yes. Alternates are measured and priced as their own line items so the base bid stays clean and each alternate can be accepted or rejected independently. When a project is split into bid packages by trade or phase, the quantities are grouped to match the package boundaries, and shared items such as temporary power or scaffolding are assigned once to avoid double counting.
Do you provide quantity surveyor services for renovation and tenant fit-out work?
Yes, and the measurement rule changes. Renovation takeoffs start from existing conditions: verify wall types and heights from the demolition and existing plans, measure new partitions net of openings, and carry patching, temporary protection, and selective demolition as their own line items. Where drawings conflict with the site, we flag the assumption on the marked-up sheet rather than guessing silently.
How do you keep the numbers traceable?
Every line carries the sheet reference, the measurement rule, the arithmetic, and the source of the unit price. The workbook ships with marked-up drawing pages showing where each quantity came from, and the PDF summary rolls the lines up by division. A reviewer can follow any total back to a dimension on a sheet without calling us.
Can you work from a partial set or design development drawings?
Yes, with the estimate class stated on the cover. Schematic and design-development sets support a conceptual estimate with allowances for undefined scope, while construction documents support a detailed bill of quantities. The AACE estimate class tells you the expected accuracy range, so a budget figure is not mistaken for a bid figure.
