What Is a Material Takeoff, and Why Smart Contractors Don't Skip It
Plans tell you what to build — a material takeoff tells you what it’s going to take to build it, and getting that wrong on a multi-family project is an expensive lesson.
A material takeoff is a complete, itemized list of every building material needed to complete a construction project — derived from the plans, specs, and scope — used to purchase the right materials in the right quantities at the right time.
For a single-family home, skipping a formal takeoff is a manageable risk. For a multi-family project with dozens of units, multiple floor types, and varying finish specs by area, it's a costly one.
Knowing what’s included in a material takeoff will help you understand why they’re so critical to keeping projects on budget and on schedule.
What a Material Takeoff Actually Includes
A quote and a takeoff serve different purposes in the construction process. A material takeoff is a breakdown of how much of each material is required for a project, focusing on quantity, while a quote uses that information to come up with pricing. This means that if a takeoff is incorrect, the quote built from it will also be inaccurate.
A full project takeoff at Miller’s Building Supply spans lumber, panels, drywall, drywall mud, drywall tools, scaffolding, steel framing, siding, insulation, hardware, roofing, roof and floor trusses, wall panelization, engineered wood products, windows and exterior doors, decking and railing, bag cement, basic plumbing, basic electrical, window wells, ceiling tiles, and steel support posts.
To make sure these quantities reflect real-world jobsite conditions, material takeoffs account for the realities of construction projects. Miller’s builds waste factors, breakage, cutting loss, and standard overages into every takeoff to help crews avoid costly delays and reordering.
Research cited by the EPA and industry analysts suggests that as much as 30% of building materials delivered to a typical construction site can end up as waste. That makes accurate waste factor calculations in a takeoff a direct line item protection for project margins.
Understanding what goes into a takeoff makes it easier to see what’s at stake when one is skipped, rushed, or built from incomplete information.
What Happens When Contractors Skip It (Or Rush It)
Skipping or rushing a material takeoff puts contractors at risk of over-ordering or under-ordering materials, both of which can drive up costs, delay a project, and create inefficiency.
When over-ordering, excess material eats into project margins and creates unnecessary storage issues on the jobsite. Under-ordering leads to scrambling mid-project, causing delays in the timeline and frustrating clients. Wrong product specifications occur when contractors order or install incorrect materials, like using fire-rated drywall instead of standard drywall or selecting the wrong insulation R-value for the application.
From Stuckey’s experience, the most expensive type of specification mistake on larger projects is when structural prints are over-structured.
“Architects do not want to take responsibility for a project underperforming, so they will tend to overbuild a project to withstand a hurricane on a project being built in the Midwest,” he says. “That may be oversimplifying it, but that’s the general idea. When this is done, it will overinflate estimates to the point where the customer will not build the project because it’s too expensive.”
The cost of correcting an error on a project is likely going to be higher than the cost of getting a material takeoff. Reordering materials, managing labor disruptions, and handling frustrated clients all cost more than getting the takeoff right the first time.
According to the Construction Industry Institute, direct field rework averages 5% of total project costs and can climb to as high as 20%. On a $50 million build, that floor-level figure alone represents $2.5 million in avoidable expenses.
For example, consider a 48-unit apartment project. If a contractor orders the wrong kind of drywall — standard instead of fire-rated — the error multiplies across all units. If the project is already underway when the error is discovered, it doesn’t just mean reordering materials — it can also require rescheduling labor and repeating inspections.
“Whether it’s a small residential home or a large multi-family home, it’s not when the takeoff is done, it’s how soon the contractor starts from the time the estimate is done,” says Doug Stuckey, the chief operating officer of Miller’s Building Supply. “Estimates are only held for a small period, typically 2 to 4 weeks at most.”
Since the lumber industry is a commodity, it’s constantly moving up and down in pricing, he says.
Framing lumber costs climbed 11.71% between Q2 2024 and April 2025, according to Gordian’s construction cost data. Tariffs on Canadian imports added further upward pressure on top of that. Movement like that in a short window is exactly why lumberyards can’t hold pricing long.
“Lumberyards cannot afford to hold pricing because they can quickly be upside down on a project if the lumber market moves up too quickly,” Stuckey says.
Having a detailed takeoff helps keep the project moving smoothly. Engineered lumber and custom-spec items require additional lead time, for example.
“If a project starts and subcontracts are scheduled ahead of time, if products don’t arrive when your subcontractor is ready, it will push every subcontractor behind them out further,” Stuckey says. “This is the most difficult part of managing a jobsite.”
Accuracy in takeoff is about avoiding errors and threading the needle between a bid that’s too lean and one that prices a contractor out of a job.
“There’s a fine line between overestimating materials in a takeoff and underestimating materials,” Stuckey says.
The goal is to accurately estimate enough materials to complete the job with a small buffer, without overestimating so much that the bid becomes uncompetitive. In multi-family projects, the stakes are higher because the supplier is responsible for guaranteeing all materials at the agreed contract price.
“The larger the job is, the more room there is for a small number of errors,” Stuckey says. “However, if the error is too large, then the losses can be catastrophic.”
To receive an accurate takeoff, contractors need to provide complete architectural plans and specifications.
“For a residential home or a multi-family project, we need a valid set of prints to work on,” Stuckey says. “If we’re dealing with a small remodel, most of our contractors know what they will need.”
Unit count and floor plan types are especially important in multi-family projects, where variations between layouts directly impact material quantities and distribution. Finish schedules by area must also be carefully reviewed, particularly to identify where moisture-resistant board is required and where Type X drywall is specified. Contractors should also provide their timeline and phasing schedule — when materials are needed and in what sequence, as well as any known supply constraints or product preferences.
When contractors submit incomplete plans or specs, it affects the accuracy of the takeoff. The same over-ordering, under-ordering, and specification errors that result from a rushed takeoff can just as easily result from incomplete information. The takeoff is only as accurate as the plans behind it.
A joint study by PlanGrid and FMI found that poor project data and miscommunication drive 48% of all rework on United States jobsites. That’s more than $31 billion in annual costs that trace back to incomplete or inaccurate information going into the build.
“In the residential construction industry, estimates are just that — they’re estimates,” Stuckey says. “Lumberyards do not guarantee material quantities being used. It is still up to the contractor to verify the estimate and verify specifics on their prints.”
Once a contractor hands over a print, it goes to Miller’s estimating department for a takeoff. If the customer is new, they will be assigned a salesman.
“If any technical or structural questions arise from our end, the estimator or salesmen will talk to the contractor for answers,” Stuckey says. “Once the takeoff is completed and entered into an estimate, the salesmen will hand it over to the contractor.”
For multi-family projects, Miller’s won’t provide an estimate without complete architectural and structural prints. Having these requirements allows Miller’s to guarantee material quantities for multi-family projects.
If the contractor needs a load calculation on an addition, Bruce Nofziger, head estimator at Miller’s Building Supply, can also provide that. Nofziger comes from a construction background, and salesmen also help in estimating if they have time, since they also have construction backgrounds. At Miller’s Building Supply, Nofziger handles structural calculations primarily and then hands them over to the salesmen.
Getting the takeoff right is the foundation, but contractors who treat takeoff data as a planning tool rather than just an ordering checklist get significantly more value out of the process.
How Do Contractors Use Takeoff Data Beyond Material Ordering?
Takeoff data informs more than just material ordering. The detailed quantities that takeoffs provide allow contractors to more accurately define subcontractor scopes of work, bid packages, and to schedule the project around the specified material needs.
Stuckey says that from his experience as a builder, the size of the estimate determines scheduling; if material quantities aren’t understood, it confuses the timeline, resulting in more money spent and more delays.
Using takeoff data to identify long-lead items early, such as engineered materials or specialty finishes, helps contractors place orders in advance and prevent delays that can impact the project schedule.
Contractors use takeoff revisions during design development to value-engineer the project by adjusting material selections, refining quantities, and aligning specifications with budget goals while maintaining overall build quality.
Sometimes, contractors are surprised to learn how Miller’s Building Supply forms its materials takeoffs.
“We build our estimates on paper like we would physically build a home in the field,” Stuckey says. “We start at the foundation and move up through each level until we reach the roof. The estimate will follow the guideline with levels called out throughout the estimate.”
A supplier that builds takeoffs the way a crew builds a structure understands how all the moving parts of a project come together, and brings that same sequencing discipline to material planning and delivery.
How Far in Advance Should You Request a Takeoff?
Lead time for material takeoffs depends heavily on project size, with larger multi-family developments requiring more planning and coordination than smaller residential builds. For multi-family projects in particular, takeoffs should begin before subcontractor bids go out so that scopes, pricing, and schedules are based on accurate material quantities from the start.
Timing is also critical for locking in pricing. Early takeoffs give contractors a better chance to secure materials before market fluctuations impact costs. To turn a takeoff around quickly, a supplier needs complete and well-organized plans, detailed specifications, and clear project timelines to ensure accuracy and efficiency.
Miller’s Building Supply aims to stay under a two-week lead time and will communicate honestly with customers if the workload is piling up. For contractors managing tight bid windows or phased build schedules, that turnaround preserves critical planning runway without pushing material decisions into a pricing risk window.
“A contractor should be talking to us as soon as the prints are complete,” Stuckey says. “Any time before that will not let the project move forward. For smaller 10-unit projects, I’d allow 4 to 5 months. On large projects that are 200 units and over, 12 to 16 months are needed.”
Once you understand how early the process needs to start, the next question is whether your current supplier has the estimating depth to support it.
What Should You Look for in a Lumber Yard That Offers Full Takeoff Services?
A counter quote is typically a quick, high-level price estimate provided on the spot, often based on limited information or past project experience, while a formal takeoff is a detailed breakdown of every material needed.
“A counter quote on a home or multi-family project, in practical terms, will never happen,” Stuckey says. “You cannot receive an accurate takeoff over the counter.”
For contractors who have been handling takeoffs themselves or relying on their own estimator, partnering with Miller’s provides support, accuracy, and efficiency. Working with a team that understands the ins and outs of the construction industry helps reduce errors and keep projects on track.
“Estimating is something we are doing daily, so the chances of us making a mistake are much lower than someone else who doesn’t have time or the experience,” Stuckey says.
When looking for a building supplier who provides full takeoffs, look for a supplier that prioritizes relationships and accuracy and brings the experience to support your project every step of the way.
