A construction takeoff is the measured list of every item the drawings show, organized so you can price it, buy from it, or send it to a subcontractor. We measure from the issued set — architectural, structural, civil, MEP — and return quantities by CSI MasterFormat division with the unit basis stated on each line. If you need the pricing that follows, that is a separate step: see our Construction Cost Estimating Services for unit costs applied to these quantities.

You need this service when you are bidding, buying, or checking a subcontractor's number. It is the measurement phase of Construction Estimating Services, and it is the parent of every trade takeoff we produce. For a single trade only, Quantity Takeoff Services covers that narrower scope.
Our takeoff is organized by division and section, with a separate line for each material type, thickness, or system. We mark up the plan set so you can see the extent we measured — wall runs, footing lengths, roof areas — and reconcile it against your own reading. Excel and PDF are standard; we work in Bluebeam Revu, PlanSwift, and RSMeans data, and we apply ZIP-code-adjusted material and labor pricing when pricing is requested. Most projects turn around in 24–48 hours, and rush is available. If you have a set ready, get an estimate and we will confirm scope and timing.
As an outsourced construction takeoff company, we read the bid documents the way your estimator does: plan reading starts with the general notes and finish schedules, then moves to on-screen takeoff in Bluebeam Revu or PlanSwift, where every wall run is measured in linear feet and every slab in square feet. We record material takeoff quantities by assembly, note where labor hours and unit price will attach, and flag items that suit parametric estimating when drawings are still schematic. We also check means and methods against OSHA access and fall-protection clearances, since a missing stair or guard changes the quantity you buy. For a named construction estimator on your account, see Dedicated Construction Estimator; to hand the whole measurement phase to us, see Outsource Estimating Services.
What our material takeoff services cover
We measure the full project from the drawings and specifications you send. The takeoff is organized by CSI MasterFormat division, with each line showing quantity, unit, and the sheet or detail it came from. If you only need one trade, we can scope to that division; if you need the whole project, we measure all divisions in the set.

How our construction estimator takes off your project
- Review the setWe log every sheet in the issued set — architectural, structural, civil, MEP, and specifications — and note the date and revision. We check that the drawings are coordinated: grid lines match, floor-to-floor heights agree, and the spec sections referenced on the drawings are included. Missing sheets or uncoordinated sets are flagged before measuring starts.
- Set up the takeoffWe scale each drawing in Bluebeam Revu or PlanSwift and set the units to match the project. We create a division-based workbook and name each measurement group after the sheet and detail it comes from. For example, footings on S-101 are measured as one group, stem walls on S-102 as another, so you can trace any line back to its source.
- Measure by divisionWe measure in a fixed sequence: sitework and earthwork first, then concrete, masonry, metals, wood, thermal and moisture, openings, finishes, and finally MEP. Each line gets a quantity, unit, and sheet reference. We count doors and windows by type and size, measure wall and ceiling areas by room, and run pipe and conduit by size and material.
- Apply waste and lapsWe add waste factors as separate lines so you can see the base quantity and the allowance. Typical waste ranges are 5–10% for concrete, 5–10% for framing lumber, 10–15% for roofing on hip and valley roofs, and 5–10% for tile and flooring. Rebar laps, dowels, and column ties are added to the calculated weight, not left out.
- Check against specsWe read the specifications for items that do not show on the plans: firestopping at rated penetrations, pipe and duct insulation, hangers and supports, and hardware sets. These are added to the takeoff under the division that specifies them, with a note on where they came from. This is where most takeoffs lose scope.
- Mark up and deliverWe mark up the plan set with color-coded overlays for each division so you can see exactly what we measured. The workbook is organized by CSI MasterFormat division with a summary tab and a detail tab per division. We deliver Excel and PDF, and we include a list of assumptions, exclusions, and items that need clarification.

Worked example: concrete takeoff services for a foundation wall
This example walks through a takeoff for one concrete foundation wall. Dimensions are illustrative only and do not represent any specific project.
Given:
- Wall length: 40 LF
- Wall height: 8 ft
- Wall thickness: 8 in (0.667 ft)
- Footing: 24 in wide × 12 in deep, continuous under wall
- Rebar: #5 vertical at 16 in o.c., #5 horizontal at 12 in o.c., two rows
- Formwork: both faces, 8 ft high
Step 1: Footing volume
- Cross-section area: 2 ft × 1 ft = 2 SF
- Volume: 40 LF × 2 SF = 80 CF
- Convert to CY: 80 ÷ 27 = 2.96 CY
Step 2: Wall volume
- Thickness: 8 in = 0.667 ft
- Cross-section area: 0.667 ft × 8 ft = 5.33 SF
- Volume: 40 LF × 5.33 SF = 213.3 CF
- Convert to CY: 213.3 ÷ 27 = 7.90 CY
Step 3: Formwork
- Both faces: 2 × 8 ft × 40 LF = 640 SF
- Add 5% for edges and bulkheads: 640 × 1.05 = 672 SF
Step 4: Rebar
- Vertical bars: 40 LF ÷ 1.333 ft (16 in o.c.) = 30 bars
- Length per bar: 8 ft + 1.5 ft lap = 9.5 ft
- Total vertical length: 30 × 9.5 = 285 LF
- Weight: #5 bar = 1.043 lb/ft → 285 × 1.043 = 297.3 lb
- Horizontal bars: 2 rows × 40 LF = 80 LF
- Add 10% for laps: 80 × 1.10 = 88 LF
- Weight: 88 × 1.043 = 91.8 lb
- Total rebar weight: 297.3 + 91.8 = 389.1 lb → 0.19 tons
Step 5: Waste factors
- Concrete waste: 5% → footing: 2.96 × 1.05 = 3.11 CY; wall: 7.90 × 1.05 = 8.30 CY
- Rebar waste: 5% → 0.19 × 1.05 = 0.20 tons
- Formwork waste: already included in step 3
Step 6: Summary of quantities
| Item | Quantity | Unit |
|---|---|---|
| Footing concrete | 3.11 | CY |
| Wall concrete | 8.30 | CY |
| Formwork | 672 | SF |
| Rebar #5 | 0.20 | tons |
This example shows how we separate base quantities from waste and how we document each calculation. For a full project, we apply the same method to every element and organize the results by CSI MasterFormat division. We also flag items that require special inspection or testing, such as concrete cylinder breaks per ACI 318, and note them in the assumptions. If you need a quantity takeoff for a specific trade, we can scope to that division. For full-project takeoffs, we measure all divisions shown on the drawings and specifications.
What drives the takeoff effort
Relative impact on a typical estimate for this trade, based on estimator judgment. Select a bar for details.
Drawing coordination
When architectural, structural, and MEP sheets disagree on dimensions or grid lines, we spend time reconciling them. A coordinated set with matching floor-to-floor heights and grid dimensions takes less time to measure than one with conflicts, and it reduces the risk of double-counting or missing scope.

A coordinated set with matching floor-to-floor heights and grid dimensions takes less time to measure than one with conflicts, and it reduces the risk of double-counting or missing scope.
A takeoff for a lump-sum bid needs enough detail to price each division. A takeoff for purchasing needs every stud, sheet, and fitting counted. The more granular the request, the more time we spend on each assembly, especially for MEP systems where fittings and hangers add up.
A mid-size project with repetitive floor plans and typical details measures faster per square foot than a one-off with many unique conditions. Repetition lets us measure one unit and multiply, but we still check that each occurrence matches the typical detail.
Plumbing, HVAC, and electrical takeoffs are driven by fixture and device counts, pipe and conduit runs, and equipment schedules. A project with a simple distribution system takes less time than one with complex routing, specialty systems, or extensive controls.
Specifications that call out firestopping, insulation, hangers, and supports add lines that are not visible on the plans. We read the specs to capture these items, which increases the takeoff scope but prevents a gap that would otherwise show up as a missing cost.
Vector PDFs from the design team scale cleanly and let us snap to linework. Scanned or low-resolution drawings require manual scaling and more careful checking. If you send a BIM model, we can extract quantities directly, but we still verify against the drawings for items not modeled.
Each alternate or unit-price item must be measured as a separate scope so you can price it independently. A project with three alternates and ten unit-price items takes more time than a single-scope bid, because we measure each variation and keep the quantities separate in the workbook.
When the civil set is issued separately or not at all, we have to ask for it and then measure site utilities, paving, and grading. A complete civil set with plan and profile sheets takes less time than a partial set where we have to infer pipe runs and grades from the architectural site plan.
Common takeoff gaps we catch
Most takeoff errors come from items that are shown on one sheet but specified on another, or from assumptions about what is included. Here are the gaps we look for on every project.
- Formwork taken as wall area instead of contact area on both faces. We measure formwork in SF of contact area, so a 10-foot wall with two faces gets twice the area of a single-face measure. This is where concrete quantities often go wrong.
- Rebar lap splices, dowels, and column ties not added to the calculated weight. We add laps per the typical details and dowels at construction joints, then convert to tons. Without this, the rebar tonnage can be 10–15% low.
- Blocking, backing, and nailers required by other trades but shown only on architectural details. We scan the architectural sheets for backing at toilet accessories, handrails, and casework, and add it to the rough carpentry division.
- Roofing waste on hip and valley roofs, plus flashing at walls, curbs, and penetrations. We add a waste factor based on roof geometry and count every penetration and wall flashing run in LF. This prevents a shortfall on complex roofs.
- Door and window openings counted but hardware sets, closers, and glazing not carried separately. We schedule each opening by type and add hardware sets and glazing area as separate lines, so the openings division is complete.
- Ceiling height changes and soffits missed when the reflected ceiling plan differs from the floor plan. We compare the two plans and measure ceiling areas by height and finish, including soffits and bulkheads.
- Pipe and duct insulation, hangers, and supports omitted because they are specified in a different division. We read the mechanical and plumbing specifications and add insulation, hangers, and supports to the appropriate division with a note.
- Firestopping at rated penetrations and fire-rated assembly continuity across trades. We identify rated walls and floors from the life safety plans and add firestopping at every penetration shown, plus a note for field-verified locations.
- Excavation over-excavation, backfill, and disposal not separated from structural fill. We measure over-excavation and backfill as separate lines from structural fill, and we note where disposal is required.
- Site utilities and exterior improvements left out when the civil set is issued separately. We ask for the civil set and measure site utilities, paving, and landscaping under Divisions 31 and 32, so the site package is not missing.
- Allowances and unit-price items not flagged so the estimator knows what is not a firm quantity. We mark allowances and unit-price items clearly in the workbook and list them in the assumptions, so you can handle them correctly in your bid.
- Alternates and additive/deductive items not measured separately from the base scope. We measure alternates as separate sections in the workbook and note them in the summary, so you can price them independently.
How the same drawing condition is measured by material
The unit basis and waste factor change with the material or system. This table shows how a typical wall or floor condition is measured differently depending on what it is made of.
| Material/System | Primary unit | Secondary unit | Typical waste factor |
|---|---|---|---|
| Cast-in-place concrete | CY (volume) | SF (formwork contact area) | 5–10% |
| Concrete reinforcing | TON (weight) | LF (bar length) | 5–10% |
| Unit masonry (CMU) | SF (wall area) | CY (grout), LF (bond beams) | 5–10% |
| Structural steel | TON (weight) | EA (members) | 2–5% |
| Cold-formed framing | LF (studs/tracks) | SF (sheathing) | 5–10% |
| Rough carpentry | BF or LF (lumber) | SF (sheathing) | 5–10% |
| Roofing | SQ (100 SF) | LF (flashing) | 10–15% (hip/valley) |
| Gypsum board | SF (surface area) | LF (corner bead) | 5–10% |
| Flooring (tile, resilient) | SF (area) | LF (base) | 5–10% |
| Painting | SF (surface area) | — | 5–10% |
| Plumbing | LF (pipe) | EA (fixtures) | 5–10% |
| HVAC ductwork | LB or SF (sheet metal) | EA (equipment) | 5–10% |
| Electrical | LF (conduit/wire) | EA (devices) | 5–10% |
| Earthwork | CY (volume) | SF (area) | 5–10% |
Codes, standards, and specifications that affect quantities
Building codes and standards influence what you must measure and how much material is required. The International Building Code (IBC) and International Residential Code (IRC) set minimum requirements for structural, fire, and life safety that often translate into additional quantities. For example, fire-rated assemblies require specific gypsum board thicknesses and firestopping at penetrations, which adds lines to the takeoff. The International Energy Conservation Code (IECC) mandates insulation levels and air sealing that increase insulation and sealant quantities. The National Electrical Code (NEC) dictates conduit fill, wire sizing, and device placement, affecting electrical counts. The International Plumbing Code (IPC) or Uniform Plumbing Code (UPC) governs pipe sizing and fixture counts. NFPA 13 for fire sprinklers adds piping, heads, and hangers. These codes are adopted at the state or local level, and the edition in force varies by jurisdiction. Always confirm the adopted code edition with the local building department before finalizing quantities. Specifications also reference standards like ASTM for material testing and ACI for concrete, which may require additional submittals or testing but do not usually change quantities. CSI MasterFormat divisions organize the takeoff, and the spec sections within each division tell you what is included. For instance, Division 07 covers thermal and moisture protection, including insulation and sealants, while Division 08 covers openings, including doors and hardware. When specifications call for products or installation methods beyond code minimums, quantities may increase. We read the specifications as part of the takeoff to capture these items and note where they affect the measured quantities. For example, if Division 09 specifies a Level 5 gypsum board finish, we measure additional skim coat and labor. If Division 22 calls for a specific pipe material, we adjust the takeoff accordingly. We also check for items that are specified but not shown, such as fire dampers at duct penetrations, and include them in the takeoff. This approach helps you avoid missing scope. If you need a quantity takeoff that accounts for these code and spec impacts, we can help.
