Free Concrete Takeoff Software for Contractors

A concrete takeoff is the process of measuring areas, lengths, and counts from structural drawings to calculate the cubic yards of concrete, pounds of rebar, and quantities of accessories needed for a project. The takeoff converts two-dimensional plan measurements into three-dimensional volume using the formula: area in square feet times depth in feet, divided by 27, equals cubic yards. A 1,200 square foot slab at 4 inches thick is 1,200 times 0.333 divided by 27, which equals 14.8 cubic yards. Footings use a similar formula: linear feet times width in feet times depth in feet, divided by 27. A 200-foot continuous footing that is 16 inches wide and 24 inches deep is 200 times 1.333 times 2, divided by 27, which equals 19.7 cubic yards. The takeoff also measures rebar quantities by calculating linear footage of each bar size, adding lap splice and development length allowances, and converting to weight. A complete concrete takeoff covers every pour phase: spread footings, continuous footings, grade beams, slab on grade, elevated decks, curbs, piers, and any specialty items like equipment pads and pit walls.

Measure the area in square feet and the depth in inches, then use the formula: cubic yards equals area times depth in inches, divided by 12, divided by 27. For a 1,000 square foot slab at 4 inches thick: 1,000 times 4, divided by 12, divided by 27 equals 12.35 cubic yards. For footings, measure the linear run and multiply by the cross-section: cubic yards equals linear feet times width in feet times depth in feet, divided by 27. A 150-foot footing that is 12 inches wide and 24 inches deep: 150 times 1 times 2, divided by 27 equals 11.1 cubic yards. For round piers, the formula uses pi times radius squared times depth, divided by 27. A 24-inch diameter pier 8 feet deep: 3.14159 times 1 squared times 8, divided by 27 equals 0.93 cubic yards per pier. Multiply by the pier count for total pier volume. After calculating each element, add the waste factor: 5 percent for formed slabs, 8 to 10 percent for earth-formed footings. Sum all volumes per pour phase and round up to the nearest half yard for your batch plant order.

Use 5 percent for formed slabs with good subgrade preparation, 8 to 10 percent for earth-formed footings, and 8 percent for drilled piers in stable soil. The waste factor accounts for the difference between the designed dimensions on the structural plans and the actual volume consumed in the field. Formed slabs with level, compacted subgrade and tight steel or wood forms hold close to the designed thickness. Waste comes from minor over-excavation, form bulging under head pressure, and pump truck priming volume. Earth-formed footings waste more because the excavated trench is never perfectly the width shown on the plans. A 12-inch footing in a trench that averages 14 inches wide consumes 17 percent more concrete in that section. Loose or sandy soil makes it worse. Drilled piers in collapsible soil can open beyond the specified diameter, increasing volume by 20 to 40 percent per pier, but this is highly site-specific. Complex pours with many step-downs, thickened edges, depressed slabs, and embed blockouts should use 7 to 10 percent. Simple flatwork on well-prepared subgrade can use as low as 3 percent if the forms are precise.

Yes. Easy Takeoffs is completely free with no credit card, no trial period, and no feature restrictions. Every measurement tool is available from signup: polygon for slab areas, linear for footing runs and grade beams, count for piers and embeds, measurement groups for pour phase organization, labels, and CSV export. Most concrete estimating software requires a paid subscription. PlanSwift costs $1,749 per year. STACK runs $2,599 or more per year. Bluebeam Revu costs $260 to $440 per year. On Center On-Screen Takeoff requires a perpetual license plus annual maintenance. Easy Takeoffs covers the core measurement workflow at zero cost. Upload structural plan PDFs, calibrate the scale, measure areas and lengths, group by pour phase, and export to CSV. Multiply area by depth and divide by 27 for your cubic yard total. The browser-based platform runs on any device with no installation. For concrete contractors who bid two or three projects per week, paying $146 to $217 per month for takeoff software eats directly into the already thin margins of concrete work.

Easy Takeoffs is the only genuinely free concrete takeoff tool with no trial limits, no feature gates, and no per-seat fees. Other options either charge subscriptions or restrict functionality. PlanSwift costs $1,749 per year and requires Windows. STACK offers a limited free version but restricts measurement groups and export behind paid plans starting at $2,599 per year. Bluebeam Revu is $260 to $440 per year and is a general PDF markup tool, not a dedicated concrete takeoff platform. On Center On-Screen Takeoff is a perpetual license product with annual maintenance fees. Easy Takeoffs handles the full concrete takeoff workflow from structural PDF plans: polygon areas for slabs and pads, linear measurements for footings, grade beams, and curbs, count tools for piers and embeds, color-coded measurement groups for pour phases, labels, and CSV export. The export feeds directly into Excel or Google Sheets for volume calculations. For concrete contractors who need to measure from S-sheets and convert to cubic yards, Easy Takeoffs provides the same core measurement capability as paid tools at no cost.

Create separate measurement groups for each element type or pour phase, then measure everything in one project. In Easy Takeoffs, set up groups like "Continuous Footings," "Spread Footings," "Slab on Grade," "Grade Beams," and "Piers" before starting. Assign each measurement to the correct group as you work through the structural plan. Footings use the linear tool: trace each footing run along its centerline to get the total length. Slabs use the polygon tool: trace the slab outline to get the area. Piers use the count tool: mark each pier location on the plan. Each group tracks its own running total. When you export to CSV, each group appears with its own area, linear, and count summaries. Convert each group to cubic yards separately because each element has different cross-sectional dimensions. A 12-by-24-inch footing has a very different volume-per-foot than a 4-inch slab. Keeping them in separate groups prevents mixing up the cross sections in your volume calculations.

Digital takeoff from properly scaled structural PDFs matches the designed dimensions to within 1 percent. Hand scaling with a ruler on paper prints introduces parallax, rounding errors, and accumulated inaccuracies across dozens of measurements. On a foundation with 200 linear feet of footings and a 1,200 square foot slab, a 5 percent hand-scaling error means 10 feet of missing footing and 60 square feet of missing slab, which translates to about 1.5 cubic yards of under-ordered concrete. At $155 per yard, that is $230 in material, plus the short-load delivery charge, plus pump standby. Digital takeoff eliminates these accumulation errors because the software calculates from the exact pixel coordinates you click. The accuracy depends entirely on scale calibration. Calibrate against a known dimension on every sheet, verify by measuring a second known dimension, and the measurements will match the structural engineer's design. For concrete, accuracy matters more than most trades because you cannot return unused concrete and you cannot easily get more mid-pour.

Yes. The linear measurements you take for footing and grade beam runs in Easy Takeoffs are the same measurements used for rebar calculation. Export the linear footage per element type, then multiply by the number of bars and the weight per foot for your bar size. Number 3 rebar weighs 0.376 pounds per foot. Number 4 weighs 0.668 pounds per foot. Number 5 weighs 1.043 pounds per foot. Number 6 weighs 1.502 pounds per foot. Number 7 weighs 2.044 pounds per foot. Number 8 weighs 2.670 pounds per foot. For example, 200 linear feet of continuous footing with 3 number 5 bars needs 200 times 3 times 1.043, which is 625.8 pounds. Add 7 percent for lap splices and development lengths: 669.6 pounds, or 0.33 tons. For slab rebar on a mat, calculate the number of bars in each direction based on spacing, multiply by bar length, and sum the weight. Easy Takeoffs gives you the slab area and dimensions to feed into this calculation.

Ready-mix concrete costs $140 to $200 per cubic yard depending on the mix design, location, and delivery distance. Standard 3,000 PSI concrete for residential slabs and footings runs $140 to $170 per yard. Higher strength 4,000 PSI mixes for commercial work run $150 to $185. Specialty 5,000 PSI and above for structural elements costs $160 to $200 or more. Short-load charges apply when you order less than a full truck load, typically under 10 cubic yards. The surcharge is $30 to $50 per yard on the shortage. Ordering 7 yards of a 10-yard minimum means paying full price for 10 yards worth, effectively $200+ per yard for those 7 yards. Standby time charges start 5 to 7 minutes after the truck arrives: $2 to $4 per minute while the driver waits for your crew to place and finish. Saturday delivery adds $150 to $300 per load at most plants. Pump trucks add $1,000 to $2,500 per half day depending on boom length. All of these costs are driven by the accuracy of your takeoff. Order the right amount, pour efficiently, and the per-yard cost stays at the base price.

Measure each slab section with a different thickness as a separate polygon in its own measurement group, then calculate volume for each group using that section's specific depth. A common example is a garage slab that is 4 inches thick in the center but has 12-inch thickened edges at the perimeter. Measure the flat slab area with one polygon and the thickened edge with a linear measurement of the perimeter. Calculate the flat slab volume: area times 0.333 feet divided by 27. Calculate the thickened edge volume: perimeter linear feet times edge width in feet times edge depth in feet, divided by 27. Subtract the overlap where the thickened edge footprint was already counted in the flat slab area. Other scenarios include depressed slabs at floor drains (typically 6 to 8 inches instead of 4), equipment pads at 6 to 12 inches, and topping slabs at 1.5 to 2 inches over precast planks. Label each measurement group with the thickness so your CSV export shows exactly which sections need different depth calculations.

A concrete takeoff measures quantities from the plans. A concrete estimate prices those quantities into a bid. The takeoff gives you cubic yards, linear feet of rebar, square feet of formwork, and counts of embeds and accessories. The estimate applies unit costs to each quantity. Ready-mix at $155 per yard, rebar at $0.80 to $1.20 per pound installed, formwork at $4 to $8 per square foot of contact area, finishing at $1 to $3 per square foot, and pump truck at $1,500 per half day. Labor for concrete placement runs $4 to $10 per cubic yard depending on complexity. Finishing runs $0.50 to $2 per square foot for broom finish and $2 to $5 for exposed aggregate or stamped. Add overhead for equipment, insurance, and vehicles at 15 to 20 percent of direct costs, then profit margin at 10 to 20 percent. A takeoff error cascades through the entire estimate. If you measured 35 cubic yards but the actual volume is 40, every cost downstream is understated by 14 percent. On a $50,000 foundation job, that is $7,000 in unaccounted cost.

Add 0.25 to 0.75 cubic yards to your total concrete order for pump priming, depending on the pump type and line length. A boom pump with 100 to 150 feet of line needs about 0.25 to 0.5 cubic yards to fill the boom and begin placing. A line pump (trailer-mounted) with 200 to 300 feet of hose needs 0.5 to 0.75 yards. The priming concrete goes through the pump first to lubricate the lines and push out air. Some of it ends up as waste in the washout area, especially the last yard or two at the end of the pour when the lines are cleaned. On small pours under 15 cubic yards, priming volume is a significant percentage of the total. A 10-yard pour with 0.5 yards of priming waste is 5 percent of the order. On a 50-yard pour, it is negligible at 1 percent. Factor priming into your order along with the waste factor. Your total order should be: calculated net volume, plus waste percentage, plus priming volume, rounded up to the nearest half yard.
