A construction takeoff is listing and measuring the materials needed for a project to calculate the total completion cost. The construction takeoff is the first phase in the estimation process, which involves quantifying the materials required to begin and complete the project.
What is Takeoff in Construction?
In the realm of construction, a takeoff signifies the meticulous process of ascertaining the precise quantity of materials essential for a particular project. It goes by other names like material takeoff or quantity takeoff and is indispensable for contractors to formulate precise cost estimates.
Throughout a takeoff, contractors meticulously compute the amounts of diverse materials imperative for project completion. This encompasses elements such as windows, doors, fixtures, and various other components. Takeoffs may also entail measuring dimensions like perimeter and surface area to gauge the requisite amount of flooring or wall materials.
The primary objective behind a construction takeoff is to furnish contractors with an exact tally of materials prior to tendering a bid. This practice aids in averting excessive expenditure on materials that could eat into their profits.
Takeoffs can be executed either manually or through dedicated software. Leveraging software can enhance both accuracy and efficiency during the takeoff procedure.
Difference Between a Takeoff and an Estimate
As you start working in the construction sector, you’ll want to understand the distinction between a takeoff and an estimate. A takeoff is simply calculating the quantity of all materials required for a job. That is it! Takeoffs do not include any connected material costs or additional charges that an estimate may have.
Estimates apply expenses to all materials identified by the takeoff and factor in additional costs incurred by the forecast. These extra costs include travel expenses, taxes, the application of a waste factor, labor charges, and any other fees incurred while executing the job. Many contractors utilize construction cost estimating software to make their jobs easier.
Framework for a Construction Takeoff
Accurate construction takeoff and quantification result in more profitable projects. Precise material and cost information allows estimators to allocate resources better and develop competitive bids.
But what exactly is required to perform building takeoffs properly? To answer this question, we must first establish who is involved in the process and what components are needed for takeoff.
Who Completes the Construction Takeoffs?
Estimators often perform construction takeoffs to calculate material, labor, and equipment costs to provide an accurate and competitive offer.
While each job is unique, estimators frequently rely on years of experience to determine the materials needed to finish the project. They also use their knowledge from past completed projects to uncover savings. Finally, their goal is to precisely measure the materials and compute building expenses so that they can submit a winning and lucrative offer.
Larger businesses will likely have numerous estimators working on larger, more complex projects, quantifying various scopes in which they specialize. In many circumstances, estimators consult project plans, models, and documentation before compiling a list of materials.
What is included in a construction takeoff?
A construction takeoff is a high-level inventory of the materials required for the project, including quantities and pricing. Building takeoffs are comprehensive documents that define the materials needed, as well as their measurements and prices. Estimators then enter each type of material, its description, measurement, required quantity, and cost into a spreadsheet or, better yet, an estimating software.
For example, while entering the required amount of concrete for the project, the estimator may enter the following information into the construction takeoff: QTY, UNIT SQ.FT, UNIT PRICE, and TOTAL PRICE of concrete.
How to Perform a Takeoff in Construction from Beginning to End
Now that we’ve discussed what a construction takeoff is and what it does, let’s look at the processes required to execute takeoffs in construction.
Step 1: Review the Project Plans
The initial stage in the construction takeoff process is to obtain project plans and papers. These can help you visualize the project and determine which supplies to utilize and in what quantities.
If you are performing a manual takeoff, you will need physical copies of these documents to review them by hand. You can request scanned copies to upload into the software using a digital construction takeoff solution.
Estimators pay close attention to details in project documents to ensure that they have identified all documents relevant to the scope being quantified and comprehend the documented specifications.
Step 2: Count and Make a List of the Needed Supplies
As you review the project’s blueprint, begin calculating the components required to complete the project. For example, you’ll need to know how many doors, windows, and fixtures the structure would require to evaluate expenditures.
How you implement the construction takeoff will determine the particular activities you perform at this stage. If you do things the old-fashioned way, you must count manually.
Step 3: Measure the Different Components of the Project
You’ll also need the correct measurements for anything you’re making. After verifying the scale, calculate the square footage of a given room to determine the quantities of materials required to build it, whether it’s selecting the surface area for installing drywall, paint, or insulation or calculating linear footage for trims, cables, and so on.
Again, the specific technique will be determined by whether you are undertaking manual or digital takeoffs, as well as the complexity of your project. Manual operations employ a scale ruler on paper blueprints; however, construction takeoff software can create these measurements more quickly.
Step 4: Determine Quantities
Once you’ve compiled a list of project supplies and measurements, you must determine the required quantities. Take inventory of the necessary supplies and measurements of various project components, and then utilize that information to establish the appropriate quantities.
For example, if the plan asks for a 2,600-square-foot indoor area, you’ll need to determine the necessary materials to build that room and their quantities.
Step 5: Determine the Costs
The next step is determining the costs of the goods on your list. You may need to use your industry knowledge to calculate the cost of materials. Sometimes, your suppliers may have offered quotations, which you might also use.
Construction software can also make this process easier. Some digital tools include databases with up-to-date pricing information, which estimators can use to calculate costs.
When the preceding steps are completed, you can proceed with the remainder of the estimating procedure. This calculates your other expenditures and markup for a final estimate and bid.
Benefits of Construction Takeoff Software
Construction takeoff software saves your business time and money. As previously said, construction takeoffs can be done manually or digitally. The former entails physically inspecting documents and manually counting and measuring materials. The latter can improve takeoff efficiency through automation and more user-friendly features.While adopting digital tools necessitates investing in technology, today’s takeoff software provides a high ROI. To determine which strategy is ideal for your practice, examine the following.
Save Time
Construction software such as Auto Desk Takeoff will improve every aspect of your takeoff procedure. Whether you’re counting fixtures, calculating flooring or wall surface area for painting, or attempting to get quantifiable data from a BIM model to save time, a digital solution can help.
In many circumstances, digital takeoff software can help automate some of the more laborious aspects of building takeoff. For example, AI features such as symbol detection on 2D designs can help reduce the mundane and time-consuming effort of manually removing comparable symbols such as light fixtures, outlets, columns, and doors.
Estimators are sometimes asked to create a high-level conceptual estimate for various reasons, including establishing feasibility and whether a project is worth pursuing without devoting significant effort to a comprehensive estimate. Sometimes, it’s essential to look into different material options that fit inside the project budget. Using Autodesk Takeoff’s unit cost capabilities, estimators can quickly establish an approximate budget for 2D and 3D takeoffs and see how the cost changes in their inventory as more takeoffs are performed.
Furthermore, real-time cloud-based document management allows estimating teams to access the most recent construction documentation, drawings, and models anytime.

Businesses are no longer required to store endless paperwork at their offices. Everything may be accessed and safely saved on the cloud at any time.
Future bids benefit from easy access to historical project data, which enables estimators to create more precise price estimates. Estimators frequently handle multiple projects concurrently. As a result, estimators can finish takeoff in a fourth of the time by reducing manual processes and rework.
Improve Collaboration
Large estimating teams in organizations require construction software. Using desktop-based takeoff solutions can take time and effort. Estimators cannot collaborate with other estimators on the team. They can only operate from somewhere because they must store their project files and data on their local devices.
It is challenging to make sure that everyone is using the most recent project materials and correctly accounting for all revision-related changes when there are several silos. This may lead to expensive errors that cost businesses the chance to either lose the bid or land a potentially unprofitable position.
When it comes to ensuring that all team members are always aware of the most recent information and that everyone is on the same page, cloud-based solutions like Autodesk Takeoff can make a difference.
