In the construction industry, continuous learning is always a smart idea.
Whether you’ve been building for two years or twenty, you’ll find a way to improve your process and save yourself time—or a return trip to the supply yard.
The margin for error is small in construction. One wrong measurement can eat into your profit or delay the job. That’s where a takeoff for construction comes in.
What is quantity takeoff? It’s how you figure out exactly what materials the job needs—nothing more and nothing less.
This guide walks you through what a takeoff actually is. It’ll explain how to perform one, how it ties into your estimate, and why using software can save you hours.
We’ll also cover how to pick the right software.
If you’ve ever second-guessed a count, mispriced a quote, or overspent on materials, this guide’s for you.

What Is a Construction Takeoff?
Ever ordered materials and then realized you forgot to count the trim on the back wall? That’s why takeoffs are so important.
So, what is a takeoff in construction?
A takeoff for construction is part of the estimating process. It’s where you figure out exactly what materials you’ll need to finish the job and how much of each.
You might be working from blueprints, PDFs, or a rough sketch on a napkin. Whatever the method, the takeoff helps you answer questions like:
- How many square feet of drywall?
- How many bundles of shingles?
- How much lumber for the framing?
- How many linear feet of baseboard?
It’s not just for you, either. It helps your client, too.
When you build your quote off a proper takeoff, you avoid change orders. You reduce overbuying and can back up your price with real numbers.
That protects your profit margins. It also builds trust, and high trust construction companies are twice as confident when it comes to meeting deadlines.
In short, a good takeoff means fewer surprises. It locks in a smoother build from the outset with quotes you can stand behind.

How to Perform a Construction Takeoff
Before you can price a job, you need to know what that job actually requires. The takeoff is the groundwork for an accurate estimate.
Here’s the takeoff estimating process:
Step 1: Review the Project Plans
Start by reading through the drawings or scope documents. Look at everything: floor plans, elevations, notes, specs, and so on.
You’re looking for scope and any potential surprises, like vaulted ceilings or non-standard dimensions.
Don’t rely on what the client told you. Always check the documents.
This step helps you catch red flags early and get familiar with what you’re about to count and measure.
Step 2: Count and List the Materials Required
Walk through the job mentally from demo to finish. List everything you’ll need.
That could mean things like:
- Lumber
- Drywall
- Trim
- Fasteners
- Tile
- Underlayment
- Fixtures
- Paint
You might want to break materials down by trade or phase. That makes buying and staging easier later.
If it goes into the job, it should go into the takeoff. Skipping something here throws off your whole estimate.

Step 3: Measure the Components
Use the scale on your plans or digital tools to measure the areas, lengths, and volumes you’ll be working with.
You’ll measure:
- Square footage (flooring, roofing)
- Linear footage (trim, piping, wiring)
- Cubic yards (concrete, insulation)
Your measurements affect your material counts. Precision here saves money and headaches later.
Finally, round up—but not by much. A little buffer is wise. A big one might waste your money.
Step 4: Calculate the Quantities
Next, convert those measurements into actual product needs.
For example:
- 1,200 sq ft of flooring might be 35 boxes of laminate (with overage)
- 300 linear ft of baseboard might be 30 ten-foot sticks
- 80 sq ft of tile backsplash might be 100 tiles plus 10% waste
This step turns raw numbers into order sheets. It’s the link between the plan and the price.
Double-check your math. Then check it again. It’s easy to transpose numbers or forget waste.
Step 5: Determine the Costs
Price out each line item using your supplier rates or a material database. Don’t forget fasteners and delivery fees.
This is the foundation for your quote. If your material takeoff’s not quite right, your estimate won’t be, either.
You can plug your quantities into estimating tools like Joist. This helps you create professional quotes quickly.
Step 6: Cross-Check Against Scope of Work or Bid Requirements
Once you’ve done your counts and pricing, compare your takeoff against the client’s written scope. Does it all align with the Request for Proposal (RFP) or your original walkthrough notes?
Catch any missed items or differences between what’s on paper and what’s expected. For example, if the homeowner said “premium fixtures” but the plan shows builder-grade, you’ll want to flag that early.
Use a checklist format and walk line by line.
Step 7: Add Contingency for Unknowns
If you’re working on remodels or insurance repair jobs, add a line item for contingency.
Why? Because unexpected site conditions are common. A 5-10% contingency keeps you covered without spooking the client when priced transparently.

The Difference Between Construction Material Takeoffs and Estimates
Some use the terms “takeoff” and “estimate” like they mean the same thing, but they don’t. They’re part of the same workflow, but each plays a different role.
According to the Construction Management Association of America (CMAA):
“Construction estimating is the process of evaluating all costs associated with a specific construction project. The costs generally include direct and indirect expenses, overhead, and a general contractor markup.”
You give the estimate to the client. It’s what they sign (or use to shop around).
A takeoff, on the other hand, is just the materials list. It tells you:
- What you need
- How much of it
- How it breaks down by type or phase
The takeoff is one of the inputs you use to make the estimate.

Key Differences Between Takeoffs and Estimates
Here’s how takeoffs and estimates differ.
Purpose
- Takeoff: Count materials
- Estimate: Price the entire job
Who uses it
- Takeoff: You and your crew
- Estimate: You and your client
When it’s used
- Takeoff: Early, before you quote
- Estimate: Later, before the contract is signed
What it includes
- Takeoff: Only materials (e.g., 24 sheets of drywall)
- Estimate: Materials plus labor plus margin (e.g., $3,250 drywall install)
Example
Let’s say you’re redoing a bathroom. Your takeoff shows:
- 180 sq ft of tile
- 2 gallons of waterproofing
- 1 linear drain
- 1 vanity
Your estimate turns that list into a price. It then factors in other costs like installation time and markup.
Nail the takeoff, and the estimate becomes a lot easier to trust—for you and your client.
Benefits of Using Takeoff Software
Software makes the construction takeoff process faster and far less prone to costly mistakes. Here are the benefits.
Accuracy
Manual takeoffs rely on your attention to detail. But even the best professionals make the occasional mistake.
Takeoff software lets you measure directly from digital plans. As you mark up a drawing, the software calculates square footage, linear footage, and material totals automatically.
Speed
Most material takeoff tools cut your preparation time in half. You can click and calculate in minutes instead of hours.
Some platforms save your assemblies, too, so you’re not rebuilding the same process every time.
That means more quotes delivered to your prospects.
Standardized Costs
Every time you quote a job from scratch, you risk pricing inconsistencies. With software, you can build a catalog of your typical materials and rates.
Your numbers stay aligned across jobs, even if different team members are preparing them. It also helps when clients ask why something costs what it does. You have a clear, consistent answer ready.
Time Savings
Once you’ve used takeoff software on a few jobs, the benefits compound. Templates, saved data, knowledge of features, and faster workflows take you from plan to estimate without slowing down.
Instead of burning hours doing repeat math, you can focus on the next job.
Reduced Manual Error
Mistakes in the takeoff phase have a domino effect. Miss one measurement and suddenly your quote is off, your material order is short, or your margin disappears.
Takeoff software reduces that risk. It gives you a system that checks your work and helps ensure nothing gets missed along the way.
