# Concrete Takeoff Software — Yardage, Rebar, Formwork in One Tool

Stop bouncing between Bluebeam, PlanSwift, and spreadsheets. Jobplans is browser-based concrete takeoff software that measures every concrete scope on your drawings and calculates yardage, rebar, formwork, and labor from the same measurements — in a single dynamic table. 15+ concrete-specific templates, industry-standard waste factors, and real-time collaboration across the estimating team. Runs on Mac, Windows, iPad, iPhone, Android, Chromebook, and Linux.

Measure a slab, add the depth, and watch the cubic yards, rebar weight, formwork square footage, labor hours, and total cost populate automatically. Change the slab dimensions and every downstream number recalculates. Export to CSV (Excel-compatible) or share a live link with your PM, foreman, or ready-mix supplier.

## Why concrete takeoffs are harder than they look

Concrete estimates look simple on the surface — you need cubic yards, rebar, and formwork. In practice, concrete takeoffs are some of the most error-prone scopes in construction because of the math involved and the number of components that have to stay in sync.

A typical concrete takeoff for a commercial footing and slab package requires:

- **Accurate area measurement** for every footing, slab, wall, and column.
- **Depth or thickness** for each element — often different per scope, sometimes different per zone within a single slab.
- **Cubic yard conversion** with waste factors applied.
- **Rebar calculation** based on spacing, bar size, and direction (mat vs single-direction vs stirrups).
- **Formwork area** for vertical and horizontal surfaces with reuse factors.
- **Accessory quantities** — keyways, chairs, vapor barriers, expansion joints, control joints, curing compound.
- **Labor hours** based on crew productivity for placement, finishing, and forming.
- **Equipment** — pump time, vibrators, finishing machines.

Manual takeoffs tracking all of these components across multiple scopes in a spreadsheet are slow and fragile. One wrong depth on one footing changes the entire pour, the rebar weight, the formwork area, and the labor hours. Jobplans eliminates this fragility by computing everything from the measurement data and letting you change any input with live recalculation.

## How to do a concrete takeoff with Jobplans

The step-by-step process, in practice:

1. **Identify every concrete scope on the drawings.** Review the structural and architectural drawings. Common scopes include spread footings, strip footings, pile caps, slab on grade, structural slabs, walls, columns, piers, stairs, curbs, and sidewalks. Cross-reference the structural notes for reinforcement specs.
2. **Set the drawing scale per sheet.** Jobplans auto-detects scale from written text on the sheet — title blocks, general notes, and scale callouts. When auto-detection is not reliable, calibrate manually in two clicks against any known dimension. Scale accuracy is the foundation of every downstream calculation.
3. **Measure concrete areas and add depth.** Use the area tool for slabs, the linear tool for walls, and the count tool for piers and columns. Each measurement gets a depth or thickness value, and Jobplans computes cubic yards automatically: (area × depth in inches) ÷ 324.
4. **Apply the rebar composition.** For each concrete element, specify bar size (#4, #5, #6), spacing (12", 16", 24" on center), and whether it is a mat (both directions) or single-direction. The template computes total linear footage and converts to pounds using standard weights.
5. **Compute formwork area.** Measure the perimeter of each concrete element, multiply by vertical height, and apply reuse factors. Jobplans handles this automatically for footings, walls, and columns with per-template formulas.
6. **Apply waste factors.** Industry-standard: 5–8% concrete, 5% rebar, 10% formwork. Waste factors live as explicit columns on the measurement table, not hidden in unit costs.
7. **Compute labor hours from crew productivity.** Divide the quantity by crew productivity (concrete placement 20–40 cy/day, rebar 1.5–3 tons/day, formwork 150–300 sq ft/day). Override the defaults per company or per project.
8. **Export and hand off.** Export to CSV (Excel-compatible) or share a live link with the estimating team, PM, or ready-mix supplier.

## 15+ concrete templates with live calculations

Jobplans ships 15+ concrete-specific templates covering every common scope. Each template has the right columns, formulas, waste factors, and default productivity values already wired in.

- **Spread footings.** Area × depth → yardage. Perimeter × depth → formwork. Rebar mat based on spacing.
- **Strip footings.** Linear length × width × depth → yardage. Linear formwork on both sides. Continuous rebar with laps.
- **Pile caps.** Area × depth → yardage. Formwork on perimeter. Heavy rebar cage.
- **Slab on grade.** Area × thickness → yardage. Vapor barrier area. Wire mesh or rebar mat. Control joint linear footage.
- **Structural slabs.** Area × thickness → yardage. Top and bottom reinforcement mats. Shoring and reshoring.
- **Concrete walls.** Length × height × thickness → yardage. Both-sided formwork. Vertical and horizontal reinforcement.
- **Grade beams and stem walls.** Linear length × cross-section → yardage. Both-sided formwork. Continuous rebar.
- **Concrete columns.** Count × cross-section × height → yardage. Column formwork. Vertical bars with ties or spirals.
- **Piers and caissons.** Count × cross-section × depth → yardage. Cage rebar.
- **Stairs.** Riser count + tread depth → volume estimate.
- **Curbs.** Linear length × cross-section → yardage. Extruded curb or formed curb variants.
- **Sidewalks and flatwork.** Area × thickness → yardage. Fiber mesh or rebar.
- **Driveways and aprons.** Area × thickness → yardage. Heavy-duty rebar spacing.
- **Precast footings and slabs.** Count × unit volume. No cast-in-place forming.
- **Topping slabs.** Thin slab over existing. Bonding agent, mesh, labor for hand placement.

## Yardage calculations with waste factors

Cubic yards is the single most important concrete quantity because it drives the ready-mix order. Get it wrong and either you pay for trucks you do not need or you come up short mid-pour and lose half the pour to cold joints. Jobplans computes yardage automatically from area × depth with explicit waste factors applied.

The formula Jobplans uses: `((area_sf × depth_inches) / 324) × (1 + waste_factor)`. For a 1,000 sq ft slab at 6 inches with an 8% waste factor, that produces (1000 × 6 / 324) × 1.08 = 20 cubic yards ordered. The calculation is transparent — you can see the area, depth, base yardage, and waste factor as separate columns on the measurement table, so you can verify every input before the number goes to the batch plant.

For pour scheduling, Jobplans also shows truck count based on typical ready-mix truck capacity (10 cy per truck) and lets you override for smaller trucks or split deliveries.

## Rebar estimating from spacing and bar size

Rebar is the second-largest concrete cost component after the concrete itself, and the math is notoriously easy to get wrong. The rebar composition in Jobplans computes linear footage automatically from the specified spacing and element dimensions, then converts to pounds using standard weights.

For a slab mat with #4 bars at 12" on center in both directions, on a 1,000 sq ft slab:

- Linear feet per direction = area (sq ft) ÷ spacing (feet) = 1000 ÷ 1 = 1,000 linear feet each direction
- Total linear feet (both directions) = 2,000
- With 5% lap factor = 2,100 linear feet
- Weight (#4 at 0.668 lbs/ft) = 1,403 pounds

Change the bar size to #5 and the weight recalculates to 2,190 pounds. Change the spacing to 16" and the linear feet drops to 1,575. Change the slab dimensions and everything updates. The alternative — computing this by hand in a spreadsheet — is where most rebar errors come from.

## Formwork takeoffs with reuse factors

Formwork is measured as contact area — the square footage of form in direct contact with the concrete. For a spread footing, it is perimeter × depth. For a wall, it is 2 × length × height (both sides). Jobplans computes contact area automatically from the measurement.

The key to accurate formwork costing is the reuse factor. A form panel reused 4 times on a project costs 1/4 of its purchase price per pour, plus labor per pour. Jobplans templates let you specify reuse factors per scope — typically 4 for small projects, 6–8 for repetitive commercial work. The form cost line item in the measurement table shows both the gross form area and the per-pour amortized cost.

## Pour scheduling and batch plant coordination

A concrete takeoff is not finished when the quantities are computed. You also need to know:

- **How many trucks.** Total yardage ÷ 10 cy per truck (adjust for smaller trucks).
- **Pour rate.** How fast you can place and finish determines whether a large pour needs to be split across multiple days.
- **Mix design.** PSI, slump, air content, admixtures. These come from the specs but need to be included in the order.
- **Delivery schedule.** Truck spacing based on crew placement rate. Too fast and trucks wait; too slow and concrete sets up.

Jobplans pour scheduling columns let you compute and display these values alongside the quantities so your ready-mix supplier has everything they need when you call the batch plant.

## Related materials: wire mesh, vapor barrier, and accessories

Beyond concrete, rebar, and formwork, a complete concrete estimate includes several accessory materials. Jobplans templates handle these automatically:

- **Wire mesh.** Sheet count from slab area with standard overlap (typically 6 inches). Common mesh types: 6×6 W1.4×W1.4, 6×6 W2.9×W2.9, 4×4 W4.0×W4.0.
- **Vapor barrier.** Square footage from slab area with 6-inch overlap at seams. Standard thicknesses: 6 mil, 10 mil, 15 mil.
- **Control and expansion joints.** Linear footage from slab perimeter plus any interior joints. Sawcut or formed.
- **Chairs and bolsters.** Count based on rebar grid spacing.
- **Curing compound.** Square footage of exposed slab surface with standard coverage rates.
- **Expansion joint material, backer rod, sealant.** Linear footage from joint schedule.
- **Aggregate base material.** Area × depth × density for tonnage.

## Common concrete estimating mistakes and how to avoid them

Even experienced estimators make the same concrete mistakes repeatedly. Most of them come from the number of moving parts in a concrete takeoff and the difficulty of keeping them in sync manually. Jobplans eliminates many of these by design.

- **Forgetting to add waste factors.** Quantities computed without waste produce short orders and emergency trucks. Always apply waste factors as explicit line items — not hidden in unit costs.
- **Mixing up rebar bar sizes.** #4 weighs 0.668 lbs/ft; #5 weighs 1.043 lbs/ft — the difference compounds fast across a large slab. Double-check the spec callout before pricing.
- **Carrying scale from one sheet to the next.** Detail callouts often use different scales than the main plan. Jobplans tracks scale per sheet automatically, but manual spreadsheet workflows are vulnerable to this error.
- **Missing control joints.** Sawcut control joints cost real money on large slabs but are easy to forget during takeoff. Track them as a separate linear-foot line item with a per-foot unit cost.
- **Underestimating formwork labor.** Formwork labor is typically 40–60% of total forming cost. Using only material cost without labor produces bids that lose.
- **Ignoring weather and pour sequencing.** Hot weather, cold weather, and rain all affect placement and curing. Budget for admixtures, blankets, or delays on affected projects.
- **Not accounting for pump truck costs.** A pump truck is often $1,500–$3,000 per day on commercial projects. Include it as a line item.
- **Treating every pour as the same productivity.** Basement slabs pump faster than elevated decks. Apply different productivity rates per scope.

## How Jobplans compares to manual concrete takeoff

A typical manual concrete takeoff for a mid-sized commercial project — footings, stem walls, slab on grade, columns — takes 6–12 hours with a scale ruler, calculator, and spreadsheet. The estimator measures each element, writes dimensions on a pad, computes yardage and rebar by hand, and transcribes everything into a pricing sheet. Every transcription is a chance for error, and every revision means redoing the downstream calculations.

The same takeoff on Jobplans typically runs 1–3 hours with higher accuracy. Measurements live in the tool, calculations happen automatically, and revisions recalculate live. Estimators report 3–5× productivity gains on concrete scopes after the first week of digital workflow. For teams producing 30+ concrete bids per year, the time savings compound into hundreds of hours of reclaimed capacity.

## Who uses Jobplans for concrete takeoffs

Concrete subcontractors across commercial, industrial, and residential work use Jobplans to price yardage, rebar, and formwork from the same measurements without juggling three separate spreadsheets. General contractors with in-house concrete crews produce competitive bids without outsourcing to specialty estimators. Independent estimators producing concrete bids for multiple clients use the trade templates to deliver consistent quality across every engagement. Design-build firms price concrete scopes during preconstruction with the same tool the construction team will use later. Owners running cost verification on contractor bids use Jobplans to spot-check unit rates and quantities against independent takeoffs. The common thread is anyone who needs accurate, defensible concrete quantities from a drawing set — faster than a manual takeoff and more reliable than a generic spreadsheet.

## Frequently asked questions

**How do you calculate concrete yardage for a slab?**

The formula is (area in square feet × depth in inches) ÷ 324 = cubic yards. For example, a 1,000 sq ft slab at 6 inches deep is (1000 × 6) ÷ 324 = 18.5 cubic yards. Add a 5–8% waste factor to account for spillage, over-excavation, and pump loss, bringing the order quantity to about 20 cubic yards.

**What waste factor should I use for concrete?**

Industry standard is 5–8% waste for concrete volume. Pumped concrete runs 5–6%; chute or wheelbarrow placement runs 7–8% due to higher spillage. Use the higher end of the range for small or irregular pours.

**How do I calculate rebar weight from a takeoff?**

Multiply total linear footage by the per-foot weight of the bar size: #3 = 0.376 lbs/ft, #4 = 0.668 lbs/ft, #5 = 1.043 lbs/ft, #6 = 1.502 lbs/ft, #7 = 2.044 lbs/ft, #8 = 2.670 lbs/ft. Add 5% for overlaps and bending.

**How do I calculate formwork square footage?**

Contact area is perimeter × depth for footings, 2 × length × height for walls (both sides). Apply reuse factors (4–8 per form) to determine actual forming cost per square foot.

**What is the difference between a concrete takeoff and a concrete estimate?**

A takeoff produces quantities. An estimate multiplies those quantities by unit costs and adds labor, equipment, overhead, and profit to produce a bid price. Jobplans combines both in one tool.

**How long does a concrete takeoff take on Jobplans?**

Small commercial slab: 15–30 minutes. Mid-sized commercial foundation: 1–3 hours. Large structural slab with complex reinforcement: 3–8 hours. Typically 3–5× faster than manual takeoff.

**Does Jobplans handle irregular slab shapes and cutouts?**

Yes. Polygon or polyline tool for irregular boundaries. Cutouts are drawn as separate polygons and subtracted from the enclosing slab area automatically.

**Can I use Jobplans for residential concrete takeoffs?**

Yes. Residential workflows benefit especially from the browser-based interface and flat pricing. Use the spread footing template for footings, slab-on-grade template for garage and basement slabs, sidewalk template for flatwork.
