Concrete Takeoff Software: Quantities, Labor, and Pricing
Concrete takeoffs need more than cubic yards. Learn how to capture slabs, footings, walls, rebar, forms and access, then price a clear bid.
The short answer: A concrete takeoff needs more than cubic yards. A dependable estimate covers each element (slabs, footings, walls, piers, curbs), plus reinforcing, formwork, placement method, finishing, waste and site access. Concrete takeoff software helps you measure all of it from the plans and keep it tied to the line items you price.
What a concrete takeoff has to capture
- Elements by type: slab on grade, footings (continuous and spread), grade beams, piers, foundation walls, retaining walls, stairs, curbs, sidewalks and pads.
- Volume: cubic yards per element, from length × width × depth, with thickened edges and depressions included.
- Area: square feet of slab and flatwork for finishing, curing, sealing and vapor barrier.
- Reinforcing: rebar by size and spacing (converted to weight or linear feet), dowels, wire mesh or fiber.
- Formwork: contact area or linear feet of edge form, by element, and whether forms are reused.
- Base and prep: gravel base, compaction, vapor barrier, under-slab insulation.
- Accessories: anchor bolts, embeds, expansion and control joints, waterstops.
- Placement and finish: pump vs. direct chute, finish type (broom, trowel, exposed), curing and protection.
How to approach a concrete takeoff
- Review the foundation and structural sheets together. Footing schedules, wall sections and slab details often live on different sheets.
- Read the general structural notes. Concrete strength, rebar grade, lap lengths, cover and testing requirements change the price.
- Separate elements by type. Each one has different forming, placing and finishing labor.
- Measure volume and area. Calculate CY for placement and SF for finishing. Keep them as separate quantities.
- Take off reinforcing. Count bars by size and spacing, add laps and hooks, and convert to weight if you price by the pound or ton.
- Add formwork. Measure the edges and contact area you'll actually form.
- Apply waste factors you trust from your own jobs. They vary by element and subgrade.
- Adjust labor for access and conditions: pump needs, crew size, weather, tight sites and placement height.
Worked example: one slab line
Here's how a single slab-on-grade line comes together. These are example inputs, not market prices:
- Slab: 60 ft × 40 ft × 4 in = 2,400 SF and about 29.6 CY.
- Add your waste factor (say 5%), so you order about 31 CY.
- Line items: concrete material (CY × your supplier's price), vapor barrier (SF), base gravel (tons or CY), wire mesh or rebar (SF or lbs), edge form (160 LF), placing and finishing labor (SF × your production rate), saw-cut joints (LF), curing compound (SF).
Pricing each piece separately means you can explain the number, and adjust it fast if the GC changes the thickness or the finish.
Where takeoff software saves time
- Measuring areas and lengths on PDF plans at scale.
- Converting dimensions into CY, SF and LF automatically.
- Keeping each element on its own line so changes are easy to re-price.
- Producing a proposal with clear inclusions, exclusions and alternates.
With TradeBid, you upload the plans and scope, choose Concrete, and get a draft line-item bid covering quantities, labor, materials, markup and exclusions. Every line is editable, so you set your own rates, review it, and export a branded PDF proposal.
What to check before you submit
- CY and SF are both listed where they apply.
- Reinforcing matches the schedule and details.
- Forms, base and vapor barrier are included or excluded.
- Pump, testing, winter protection and hot-weather measures are addressed.
- Excavation and backfill are clearly yours or by others.
- Finish types match the spec for each area.
Common mistakes on concrete bids
- Pricing only the slab and missing footings, piers or thickened edges.
- Forgetting pump time on sites where trucks can't reach the pour.
- One waste factor for everything, even though footings in rough soil waste more than a formed wall.
- Unclear exclusions for excavation, rebar supply or testing.
Setting labor that matches your crew
Quantities are only half the bid. The other half is how long your crew takes to install them. The most reliable concrete estimators keep their own production rates for cubic yards placed, square feet finished and linear feet formed, built from past jobs, and adjust them for pump access, weather, crew size and pour sequence.
A simple way to start:
- Pick three or four recent jobs where you know the hours.
- Divide the hours by the quantities installed to get hours per unit.
- Write down the conditions on each job, so you know when to adjust up or down.
- Update the rates after every job you finish.
Then multiply by your loaded labor rate, meaning wages plus taxes, insurance and benefits, not just the hourly wage. That's what turns a takeoff into a number you can trust. Add overhead and profit as a separate, intentional markup, so you can see exactly what you're charging for and adjust it job by job.
Presenting the bid so GCs can compare it
Most GCs line up several concrete bids side by side. Make yours easy to read: one base price, scope grouped by system or area, alternates priced separately, a short list of named exclusions, your schedule assumptions, and how many days the price is valid. A clean, branded PDF that answers their questions up front saves a round of phone calls and makes your number look more reliable.
FAQ
How do I calculate concrete yardage from plans? Multiply length × width × depth in feet, then divide by 27 to get cubic yards. Do it for each element and add your waste factor.
Should I bid concrete by the yard or by the square foot? Use both. CY drives material and placement, and SF drives finishing, curing and prep. Your proposal can show either, as long as the scope is clear.
Does takeoff software include rebar? A good concrete takeoff should. Count bars by size and spacing, or use the rebar schedule, and price by weight or length.
How does TradeBid help concrete contractors? Upload plans, pick Concrete, and review a draft line-item bid you can edit and export as a branded PDF.
