A material takeoff is a purchasing document, not a cost estimate. We measure the drawings and specifications and produce a line-by-line bill of materials, in the unit your supplier sells it in — CY of concrete, MBF of lumber, SQ of roofing, LF of pipe, EA of doors and fixtures. Waste factors are applied as separate, labeled lines so you can see the basis and adjust it. The list is organized by CSI MasterFormat division and cross-referenced to the plan sheet where each quantity was measured, so a supplier question about a footing or a duct run can be answered in seconds.

You need this when you are about to issue purchase orders, when you are collecting supplier quotes, or when you are checking whether a subcontractor's material list is complete. It also serves as the quantity base for Bid Estimating Services and Labor Cost Estimating Services.
As a material takeoff company, we work from the construction documents you send: plan sheets, schedules, specs and addenda. Measurement is done with on-screen takeoff in Bluebeam Revu and PlanSwift, priced with ZIP-code-adjusted RSMeans data where unit costs are requested, and delivered in Excel and PDF with marked-up plan sets. Turnaround is 24–48 hours for most projects, with rush available. For projects where quantities feed a full cost model, see Construction Takeoff Services.
If you are comparing in-house staff against material takeoff outsourcing, the trade-off is straightforward: we carry the software, the division checklists and the second-pass review, and you get a bid package ready list back inside two days.

What our material takeoff and estimating covers
We measure from the architectural, structural, civil, and MEP sheets, cross-checking against the specifications and addenda. Each quantity is tagged with the CSI section that governs it and the sheet it came from. Waste factors are listed separately so you can see the basis and change it. If your supplier sells by the pallet or bundle, we note the packaging unit in the delivery column.

How our material takeoff estimator works through your set
- Document intake and set-upWe log the drawing set, specifications, addenda, and any alternates. Sheets are overlaid in Bluebeam Revu so architectural and structural dimensions can be compared before measuring starts. We note the scale of each sheet and flag any sheet where the scale bar does not match the title block. We also check that the latest revision is used for each sheet; if a sheet is missing, we note it and proceed with the available information, listing assumptions.
- Structural and foundation takeoffFootings, stem walls, slabs, and columns are measured from the foundation and framing plans. Concrete is broken out by mix design and placement type; rebar is listed by bar size and bend type with lap lengths added. Formwork is measured as contact area by element, with ties and release agent listed separately. We cross-check dimensions against the structural general notes and flag any discrepancies between plan and detail dimensions.
- Architectural and envelope takeoffWalls, floors, and roof areas are measured from plan and elevation. CMU is converted from net wall area to block count by size and profile; lumber is converted to MBF by species, grade, and size. Roofing is measured in squares with hips, valleys, and flashing as separate lines. Openings are counted EA and checked against rough opening dimensions. We also verify that wall types on the plan match the wall type schedule and note any missing assemblies.
- MEP and systems takeoffPlumbing, HVAC, and electrical runs are measured by centerline length from the MEP sheets. Pipe and conduit are listed by material and diameter; duct by gauge and size. Fittings, valves, diffusers, devices, and fixtures are counted EA. Hangers, supports, and seismic bracing are measured as separate lines. We check that equipment schedules match the floor plans and flag any equipment that appears on one but not the other.
- Waste factors and packagingWaste is applied as a separate, labeled line per material — typical ranges are 5–10% for framing lumber, 10% for tile, 10–15% for roofing, and 5% for drywall. We note the supplier packaging unit (pallet, bundle, full stick) so the order quantity matches what can actually be delivered. If you have standard waste factors, we apply those instead and note the basis in the waste summary.
- QA review and deliveryA second estimator checks quantities against the marked-up plans, verifies unit conversions, and confirms that every line is tagged to a CSI section and sheet reference. The final workbook is issued in Excel and PDF with the marked-up plan set attached. We also include a summary of assumptions, exclusions, and any items that require clarification, so you can resolve them before ordering.
What we need from you
- Drawing setArchitectural, structural, civil, and MEP sheets at the latest revision. PDF is preferred; DWG helps for complex geometry.
- SpecificationsProject manual with CSI sections, so materials and thicknesses are taken from the spec, not assumed from the drawings.
- Addenda and alternatesAny addenda issued after the base bid, plus a list of alternates, so quantities reflect the current scope.
- Waste basisYour standard waste factors by material, or confirmation that you want us to apply typical industry ranges.
- Packaging preferencesIf your supplier sells by pallet, bundle, or full stick, tell us so the order quantity is rounded to the purchasing unit.
- Delivery formatExcel for sorting and supplier quotes, PDF for review, or both. We can match your existing takeoff template.

Units of measure in our material quantity takeoff
Every line on a takeoff carries the unit your supplier quotes in. These are the units we measure and the method behind each.
| Item | Unit | How it's measured |
|---|---|---|
| Cast-in-place concrete | CY | Volume = area × thickness ÷ 27, by placement type and mix design |
| Reinforcing steel | LB / TON | Bar length × unit weight per size, plus laps and cutting waste |
| Formwork | SFCA | Contact area of form surface against concrete, by element |
| Unit masonry | SF | Net wall area minus openings, converted to CMU count by block size |
| Rough carpentry | MBF / LF | Board feet = nominal thickness × width × length ÷ 12, by grade and species |
| Structural steel | TON | Shape weight per foot × length, by beam and column mark |
| Insulation | SF / CF | Area by R-value and location; loose fill converted to CF at specified depth |
| Roofing | SQ | 100 SF of roof surface, plus hips, valleys, and waste as separate lines |
| Pipe and conduit | LF | Centerline run length by material and diameter, plus fittings counted EA |
| Duct | LB / SF | Surface area or weight by gauge and size, plus insulation and sealant |
Worked example: material takeoff for a cast-in-place concrete wall
This example walks through a takeoff for a single concrete wall. All dimensions are illustrative and do not represent any specific project.
Given: A continuous footing 24" wide × 12" deep, 100 LF long. A stem wall 8" thick × 4'-0" high, 100 LF long. A slab-on-grade 5" thick, 20' × 30' (600 SF). Concrete mix: 4000 psi. Rebar: #4 bars at 12" o.c. each way in footing; #4 verticals at 16" o.c. in stem wall, two horizontal #4 continuous.
Step 1: Footing concrete volume
- Cross-section area = 2.0' × 1.0' = 2.0 SF
- Volume = 100 LF × 2.0 SF = 200 CF
- Convert to CY: 200 ÷ 27 = 7.41 CY
Step 2: Stem wall concrete volume
- Thickness = 8" = 0.667'
- Cross-section area = 0.667' × 4.0' = 2.668 SF
- Volume = 100 LF × 2.668 SF = 266.8 CF
- Convert to CY: 266.8 ÷ 27 = 9.88 CY
Step 3: Slab-on-grade concrete volume
- Thickness = 5" = 0.417'
- Volume = 600 SF × 0.417' = 250.2 CF
- Convert to CY: 250.2 ÷ 27 = 9.27 CY
Step 4: Total concrete
- Footing: 7.41 CY
- Stem wall: 9.88 CY
- Slab: 9.27 CY
- Total = 26.56 CY
Step 5: Rebar in footing
- Longitudinal bars: 4 bars continuous (top and bottom, 2 each) = 4 × 100 LF = 400 LF
- Transverse bars: at 12" o.c. over 100 LF = 100 bars, each 2.0' long = 200 LF
- Total footing rebar = 600 LF
- Convert to LB: #4 bar weighs 0.668 lb/ft → 600 × 0.668 = 400.8 LB
Step 6: Rebar in stem wall
- Verticals: at 16" o.c. over 100 LF = 75 bars, each 4.0' + lap 2.0' = 6.0' → 75 × 6.0 = 450 LF
- Horizontals: 2 continuous × 100 LF = 200 LF, plus laps (assume 5% waste) → 210 LF
- Total stem wall rebar = 660 LF
- Convert to LB: 660 × 0.668 = 440.9 LB
Step 7: Total rebar
- Footing: 400.8 LB
- Stem wall: 440.9 LB
- Total = 841.7 LB
Step 8: Formwork contact area
- Footing: two sides, 100 LF × 1.0' high = 200 SFCA
- Stem wall: two sides, 100 LF × 4.0' high = 800 SFCA
- Total = 1,000 SFCA
Step 9: Waste factors (separate lines)
- Concrete: typical 5% waste → 26.56 CY × 0.05 = 1.33 CY
- Rebar: typical 5% waste for cutting and laps → 841.7 LB × 0.05 = 42.1 LB
- Formwork: typical 10% waste for ties and damage → 1,000 SFCA × 0.10 = 100 SFCA
Step 10: Order quantities
- Concrete: 26.56 + 1.33 = 27.89 CY (round to 28 CY)
- Rebar: 841.7 + 42.1 = 883.8 LB (order 884 LB or 0.44 TON)
- Formwork: 1,000 + 100 = 1,100 SFCA
This example shows how each quantity is derived and how waste is added as a separate step. Your project will have different dimensions and specifications; the method remains the same.
What drives the cost and effort of outsourced material takeoff
Relative impact on a typical estimate for this trade, based on estimator judgment. Select a bar for details.
Drawing completeness
A set with coordinated architectural, structural, and MEP sheets takes less time than one where dimensions must be scaled from PDFs. Missing details mean assumptions, and assumptions need to be listed and confirmed. If sections or details are missing, we note them and proceed with the best available information, but the takeoff may require revision once those details are provided.

Missing details mean assumptions, and assumptions need to be listed and confirmed. If sections or details are missing, we note them and proceed with the best available information, but the takeoff may require revision once those details are provided.
A bare material list is faster than one with fasteners, adhesives, and consumables broken out. If you need packaging units or supplier-specific formats, that adds line-item work. For example, listing screws by length and type for each framing condition takes more time than a simple LF of studs. We can adjust the level of detail to match your purchasing process.
A single-trade takeoff (concrete only) is quicker than a full building takeoff across Divisions 03 through 26. Multi-division projects require cross-checking between sheets. For instance, a full takeoff includes verifying that wall types on architectural sheets match structural framing and MEP penetrations. Each additional division adds coordination time.
Applying your standard waste factors is straightforward. Developing project-specific factors from scrap plans or attic stock requirements takes additional review. If the spec requires a certain percentage of extra material for owner stock, we calculate that separately. We also consider whether waste factors should vary by material type and installation method.
Addenda and ASI changes after the initial takeoff require re-measuring affected areas. Tracking which lines changed is easier when the original takeoff is well-tagged. If multiple revisions are expected, we can set up the workbook to track changes by revision number. This adds time but provides a clear audit trail for quantity adjustments.
Delivering in your existing Excel template or with specific column headers takes set-up time. Standard CSI-organized output is faster. If you need integration with estimating software or a specific unit format, we can accommodate that, but it may require additional formatting and validation steps. We can also provide a CSV export for import into other systems.
Larger projects with more sheets and intricate details naturally take longer. A high-rise with repetitive floors may be faster per square foot than a one-off custom home with unique details. Complexity factors include irregular geometry, extensive MEP systems, and special finishes. We assess these during intake and adjust the schedule accordingly.
Common gaps we catch in material takeoff for contractors
These are the items that most often go missing from a material list and come back as a supplier shortfall or a field purchase.
- Waste factors applied inconsistently or omitted entirely. Typical ranges are 5–10% for framing lumber, 10% for tile, 10–15% for roofing, and 5% for drywall. We list waste as a separate line so the basis is visible and adjustable.
- Fasteners, adhesives, and consumables — screws, nails, structural connectors, tape, mud, thinset, and sealant. These are often excluded from a bare material list; we either include them or flag them as excluded.
- Formwork accessories — ties, snap ties, form release, chamfer strips, and shoring. These hide in the concrete notes and are frequently missing from the material list; we measure them from the formwork plan.
- Reinforcement lap lengths and cutting waste. A bar list that omits laps and waste comes in short at the supplier; we add laps per the structural notes and note the waste allowance.
- MEP hangers, supports, and seismic bracing. Pipe hangers, duct supports, and conduit trapeze are commonly omitted; we measure them from the MEP sheets and the structural coordination drawings.
- Roofing accessories — underlayment, drip edge, valley metal, pipe boots, and vents. These are missed when only membrane square footage is counted; we list them by LF and EA.
- Blocking, backing, and firestopping — wood blocking for grab bars, TV mounts, and casework, plus firestop sealant at rated penetrations. We catch these by reviewing the architectural details and life safety plans.
- Door and window rough opening dimensions versus actual unit sizes. A unit counted correctly can still be ordered wrong; we check the rough opening against the schedule and flag discrepancies.
- Unit conversion errors — SF of wall versus number of CMU, SF of slab versus CY of concrete, LF of pipe versus number of sticks or joints. We run a second check on every conversion.
- Specified alternates and addenda. Material substitutions and added scope that change quantities after the initial takeoff; we log addenda and mark affected lines.
- Salvage, overage, and attic stock. Owner-required spare material, typically 2–5% for finishes, must be ordered and listed; we add it as a separate line when the spec requires it.
- Freight, minimum order quantities, and packaging units. Suppliers sell by pallet, bundle, or full stick, not by the fractional unit on the takeoff; we note the packaging unit so the order can be rounded correctly.
Material options by CSI division and their takeoff implications

| Electrical conduit | EMT, PVC, rigid, flexible | LF | 5–10% | 26 05 00 |
Codes and standards that affect material quantities
Model codes
Model codes set minimum requirements that change material quantities. The International Building Code (IBC) and International Residential Code (IRC) govern structural, fire, and life-safety provisions. For concrete, ACI 318 is referenced for reinforcement details. The International Energy Conservation Code (IECC) dictates insulation R-values and fenestration U-factors, directly affecting insulation and window quantities. The National Electrical Code (NEC) specifies conductor and conduit sizing. The International Plumbing Code (IPC) and Uniform Plumbing Code (UPC) set pipe materials and sizing. NFPA 13 governs fire sprinkler layout and pipe sizes. Always confirm the adopted code edition with the local building department, as editions vary by jurisdiction.
Industry standards
Industry standards from ACI, ASTM, SMACNA, GA, and NRCA provide detailed material specifications. ACI 318 and ACI 301 cover concrete materials and construction. ASTM standards specify rebar grades, concrete testing, and masonry units. SMACNA standards govern duct construction and installation, affecting duct gauge and reinforcement. GA-216 provides gypsum board application requirements, influencing fastener spacing and board thickness. NRCA guidelines detail roofing system components, including underlayment and flashing. These standards often dictate material types and quantities beyond code minimums.
Specification sections
CSI MasterFormat sections define the specific materials and installation requirements. Division 03 sections specify concrete mix designs, reinforcement grades, and formwork materials. Division 04 covers masonry units, mortar, and reinforcement. Division 05 includes structural steel and cold-formed framing. Division 06 covers rough carpentry, including lumber species and grades. Division 07 covers insulation, roofing, and waterproofing. Division 08 covers doors, windows, and hardware. Division 09 covers finishes like gypsum board and flooring. Division 22, 23, and 26 cover plumbing, HVAC, and electrical materials. Each section's requirements directly impact the takeoff quantities and waste factors.
Local amendments
Local amendments to model codes can change material requirements. For example, some jurisdictions require higher insulation R-values than the IECC minimum, increasing insulation quantities. Others have specific fire-resistance requirements that affect gypsum board thickness and firestopping. Seismic zones may require additional bracing for MEP systems, adding hangers and supports. Wind-borne debris regions affect window and door impact ratings, potentially requiring different glazing. Because adopted editions and amendments vary, you must confirm the specific requirements with the local building department before finalizing material orders.
Who uses our material estimating services
General contractors
You use the takeoff to issue purchase orders and to check subcontractor material lists for completeness. It also feeds your bid estimate and your schedule of values.
Subcontractors
You use it to price your scope accurately and to order material without overbuying. The division-organized format makes it easy to pull just your trade's lines.
Suppliers and vendors
You receive a clean material list with units and quantities that match how you sell — CY, MBF, SQ, LF, EA — so you can quote without re-measuring.
Developers and owners
You use the takeoff to validate a contractor's material budget and to understand where the big-ticket quantities are before construction starts.
Architects and engineers
You use it as a check on your own drawings — if a quantity looks off, it often points to a missing detail or a dimension that needs clarification.
