If you're a contractor, you might have heard the word "takeoff" thrown around during project discussions. It doesn't involve airplanes, but it is a critical step before your project can actually ‘take off’. A takeoff is simply the process of figuring out exactly how much of each material you'll need for a project.
However, a construction takeoff serves a purpose beyond simply providing the quantity of materials needed for the project. With the ever-increasing rise in construction costs, a precise takeoff is more important than ever. Your estimate - for materials, labor, equipment, time and budget all depends on how accurate your takeoff is in the first place. So, how do you ensure an effective takeoff process?
In this article, we'll talk about what a construction takeoff is, why it is so important, how you do a takeoff, which way is best for you, and more.
So, buckle up and get ready for an insightful read.
What is a Takeoff in construction?
Takeoff in construction is the first step in accurately determining the materials needed to bring a project to life. It's the meticulous process of identifying and quantifying all the materials listed on the project blueprints/plansets. The term “take-off” simply refers to estimators “taking off” each material required for the project from the blueprints. It's like creating a detailed shopping list to ensure you have the right amount of everything from lumber to the electrical conduit.
At its core, a construction takeoff involves meticulous calculations based on four key types of measurements:
- Count: This applies to materials that are typically purchased or installed in individual units. Examples include doors, windows, light fixtures, plumbing faucets, and specific types of hardware.
- Length: This measurement is used for linear materials, such as lumber (boards, studs), pipes (conduit, electrical), and trim (baseboards, crown molding).
- Area: This measurement is crucial for sheet materials like drywall panels, plywood sheets, flooring materials (tiles, vinyl planks), and roofing materials (shingles, metal panels).
- Volume: This measurement comes into play for bulk materials like concrete, gravel, and insulation. Estimators will use blueprint dimensions to calculate the cubic yardage required for each material, ensuring enough is ordered to fill designated spaces.
By diligently measuring and calculating these four elements: count, length, area, and volume, a construction takeoff provides a comprehensive picture of all the materials needed for the project. This information is then used for various crucial tasks, laying the foundation for success throughout the construction process.
Why are construction takeoffs important?
Construction takeoffs aren't just about creating a comprehensive material list; they play a vital role throughout various stages of the construction process. Here’s how:
1. Give Insights on the Quantity of Materials Needed:
With construction takeoff, you can determine the exact quantities of materials that need to be ordered for a project. This allows contractors to plan material purchases effectively, negotiate with suppliers for bulk discounts, and ensure materials arrive on-site when needed. Why is it such a big deal, you might ask?
If you order a larger material quantity than required, it will hurt your profit margins, and you might actually end up losing the bid to your competitor. By knowing exactly what materials are required and when, project managers can streamline procurement, optimize resource allocation, and ensure a smooth workflow throughout the project lifecycle.
2. Accurate Project Budgeting
A precise takeoff forms the foundation for creating realistic project budgets. By accurately accessing material needs, you can avoid nasty surprises down the road. Underestimating materials can lead to cost overruns and project delays while overestimation ties up unnecessary funds. In fact, you might not win the bid in the first place because your quote is significantly higher than the competitors. A well-done takeoff ensures your budget reflects reality, keeping your project on track financially.
3. Improve Project Management
We all have suffered from extremely tight deadlines leading to extended working hours for teams, teams’ morale, and so on. What is the root cause? Somewhere along the line, we overcommit to the things that we have never done before. The same happens with construction takeoff. If you are relying on guesstimation while doing a takeoff, it will likely affect the project timeline and its completion rate.
An accurate construction takeoff can help you understand the types and quantities of materials needed at each construction stage which allow for more efficient project scheduling.
4. Competitive Bidding
You might receive numerous project calls in a day, but you ignore a few of them based on back-of-the-envelope calculations, your schedule, and sometimes intuition. But the question is - How do you make an informative decision to qualify a project? The answer is via a construction takeoff.
And once a contractor decides to bid, they need to be confident in their pricing. Takeoffs play a vital role in this process. By accurately gauging material requirements, contractors can develop bids that accurately reflect their costs. This allows them to submit competitive bids that increase their chances of winning the project. So that you avoid over- or under-bidding.
How is Construction Takeoff Different From Estimation?
You might have heard people interchangeably using the terms construction takeoff and construction estimation. But are they the same? Absolutely not!
A construction takeoff focuses solely on material quantities. It lists out the required materials, their quantity, and coverage area for a project.
On the other hand, construction estimation takes the takeoff quantities a step further. It factors in material costs, labor costs, equipment rentals, and other project overhead expenses to arrive at a comprehensive project cost estimate.
In simple words, takeoff and estimation are two different processes.
- First, takeoff is done to determine the exact quantities of materials required for the project.
- Secondly, estimators determine the estimation of the project based on the takeoff done while also including factors such as labor cost, equipment cost, and other costs.
While takeoff provides the foundation by outlining what's needed for the project, estimation builds upon it to provide a complete picture of the project's costs, enabling informed decision-making and budget planning.

How to Do a Construction Takeoff?
There are two main approaches of doing construction takeoffs: manually doing takeoff by hand or using digital takeoff software. Let’s understand each approach in more detail.
Manual Takeoffs
Before the digital age dawned on the construction industry, manual takeoffs were the industry standard. Unlike its digital counterpart, this established method relies on meticulous handwork and a keen eye for detail. Essentially, it's a manual inventory process, where you are meticulously identifying and quantifying all the materials needed on a construction project based on the project blueprints. This method involves a series of steps to identify and quantify all materials needed to complete a project. Let's explore the breakdown of each step.
1. Reviewing Project Plans and Specifications
This is the first and most crucial step. You'll need a thorough understanding of the project scope before starting with the takeoff. This involves spending time examining project plans and documents like blueprints, architectural drawings, and project specifications. It is important to pay close attention to details like dimensions, trades involved, material callouts, and specific notes from engineers and architects. The more comprehensively you understand the project requirements, the more accurate your takeoff will be.
2. Identifying Required Materials
Once you grasp the project scope, the next step is to categorize the materials needed for the project for each specific trade. This could include materials like; framing lumber for carpenters, electrical conduit and wires for electricians, water utility for utility contractors, and so on. Having a clear breakdown of materials by trade ensures a well-organized takeoff sheet and simplifies the estimation process later.
3. Measuring Elements and Calculating Quantities
This is where the hard work starts. Precision is key when it comes to measuring and calculating quantities for construction projects. Using tools like a scale rule or engineer's scale, you'll measure different parts shown on the blueprints. These could be lengths, like how much electrical conduit is needed, or areas, like the amount of drywall for a wall.
Once you've got your measurements, you will then perform the necessary calculations to determine the total number of each material. For example, to figure out how much drywall a rectangular wall needs, you need to multiply its length by its height, and make sure to subtract any space taken up by windows or doors.
4. Compiling a Takeoff Sheet
The final step involves meticulously compiling all the information you've gathered into a detailed takeoff sheet. This sheet typically includes columns for listing materials by trade, descriptions of each material, unit of measure (e.g., linear feet, square feet), and the calculated quantity for each item. Maintaining a clear and organized takeoff sheet is essential for easy reference during the estimation process and for effective communication with suppliers.
Drawbacks of Manual Takeoffs:
While the manual takeoff method has served the construction industry for years, it's not without its limitations. Let's explore the key challenges associated with manual takeoffs:
- Time-Consuming and Error-Prone: The repetitive nature of manual takeoffs, with its reliance on hand measurements and calculations, can be incredibly time-consuming, especially for complex projects. This can strain resources and delay other crucial project tasks. Furthermore, the risk of human error is ever-present. A single miscalculation or missed measurement can have a domino effect, impacting the accuracy of your entire takeoff and potentially leading to costly problems down the line.
- Inefficiency for Complex Projects: As project complexity increases, the limitations of manual takeoffs become even more apparent. Managing extensive material lists for large or intricate projects can be cumbersome and error-prone using manual methods. The sheer volume of data involved can make it difficult to maintain organization and accuracy.
- Requires Specialized Skills: Effectively performing manual takeoffs requires specialized skills and training. Estimators need a strong understanding of construction practices, blueprint reading, and the ability to perform calculations accurately and efficiently. This can limit the number of personnel who can effectively contribute to the takeoff process.
Digital Takeoff Software: A Modern Approach
In recent years, digital takeoff software has emerged as a powerful alternative to traditional manual takeoffs. These software tools offer a modern approach that can significantly streamline the takeoff process, enhance efficiency, and reduce the risk of errors.
