What do I need from construction takeoff software in 2026?
Published on 11 October 2026
In short: I need five things from takeoff software, and I won't compromise on any of them. An export I can send without touching it. A workflow built for measuring, not for everything else you can do to a PDF. Pricing with no paid add-ons for the features that matter. Measurements a client can trace back to the drawing. And AI that reads the drawing for me but leaves the judgement with me. I run Alves Rowe, a preconstruction consultancy, and we built Kestrel™ to do all five. So read this knowing where I stand, and use the checks under each heading to test any tool you're considering, ours included.
Where I'm answering from
I started doing takeoffs at the beginning of my fit-out career, and not on a screen. I was on site with a scale rule, checking the lengths of partitioning against the drawings. At the fit-out contractor I moved to next, that became full digital takeoffs in PDF-XChange Editor, a PDF editor with measuring tools.
Today I price work for clients through my own consultancy. This year that has been office fit-out, self storage, distribution warehouses, residential and dance studios, with construction values typically between £500k and £5m. I measure the architectural packages: drylining, floor finishes, tiling and decorating. A job can arrive as a single conceptual drawing or a pack of 50 sheets, and the return is usually due 'as soon as possible'.
That's the lens for everything below. If you price groundworks or M&E, some of your priorities will be different, but I'd expect most of these five to carry over.
Bending a PDF editor into a takeoff tool
It didn't take long to see that PDF-XChange wasn't suited to the workflow. It was never designed as a takeoff tool. I was bending it to my use case, and that was costing me time at every stage:
- The measuring itself was slow.
- Every measurement had to be labelled by hand, one at a time, or nobody could tell afterwards what it was.
- Everything then had to be exported to CSV, formatted, collated into one line per item, and worked through by hand: widths multiplied by heights, totals added up, units corrected.
None of that is estimating. It's admin standing between the measurement and the document a client actually wants. When I left to start my own consultancy, I realised how much more efficient I could be if I commissioned software built around my own workflow. That's where Kestrel came from.
1. An export I can send without touching it
This is the one I care about most. When I press export, the result should be ready to go out. I don't want to spend any time formatting, changing file types, or collating quantities of the same item into one line. If the software makes me do any of that, it has only done half the job.
For my work, "ready to go out" means a bill of quantities in Excel, set out to NRM2, with one line per item, grouped by work section and element, with the right unit and the quantity already summed. It means the bill is ready for my rates, not just a dump of raw measurements. And when a job is split into zones or phases, it means the split is already there on export, so I'm not cutting one total back into eight by hand.
That's how Kestrel exports: an NRM2 workbook with every measured item grouped and totalled, a zone summary sheet with a subtotal for each zone, the marked-up PDFs, and a drawing register, all from one export dialog. If you want the background on the format, there's a guide to what an NRM2 bill of quantities is.
Test it in your trial: measure one room, export, and open the file. Count how many things you'd have to change before you'd send it. Anything above zero is time you'll pay on every job.
2. A workflow built for takeoff, not for everything else
The workflow has to make sense and be easy to use. A lot of software is bloated. It tries to cater to everyone and offer every feature, and most of those features never get touched when you're simply trying to take off.
Bluebeam is the obvious example, and I want to be fair to it. It's a very capable PDF platform, built for whole project teams: design review, markups, document control and collaboration. Takeoff is one job among many in there, and it shows in how many menus, toolsets and settings sit between you and a measured quantity. If your team lives in it all day for other reasons, that might be a fair trade. If takeoff is the job, you're paying for, and working around, a lot you don't need. We've compared the two properly in a Bluebeam alternative for UK estimators.
Test it in your trial: give yourself one real drawing and no tutorial. See how long it takes you to go from opening the PDF to a measured, labelled area. If you need the manual, so will everyone you hire.
3. Simple pricing, with no paid add-ons for the key features
I don't want to pay extra for features that are central to the job. Selling a takeoff tool and then charging more for the part that gets your quantities into a spreadsheet feels deceptive to me, and it traps you in a cycle of rising payments.
To use Bluebeam as the example again: Quantity Link, the feature that links your measurements to a spreadsheet, starts at the Complete tier, £438 per user a year including VAT. It isn't on Basics or Core. (Prices checked in October 2026; they can change.)
Kestrel is one plan, with everything in. £25 a month (or £200 a year, four months free), plus VAT. Every feature is included, for one user on one machine. The AI features run on your own API key, billed to you directly by the provider, so there's no AI add-on from us either. More on what takeoff tools charge, and what's hidden in the tiers, in how much takeoff software costs.
Test it in your trial: find the export you'll actually use every day and check which tier it's on. Then price that tier, not the headline one.
4. Measurements your client can trace
A client has to be able to point at a line or a quantity in my takeoff and see where it came from. That's not a nice-to-have. It's how queries get answered quickly, and how a client builds the trust to use my numbers without re-measuring them.
So I always send two things: the bill of quantities and the marked-up PDF. In Kestrel, each measurement on the PDF is numbered and drawn in its item's colour, and the legend carries a per-measurement key that ties every number back to its item. The client reads an item code and colour in the bill, finds the same colour on the drawing, and can check every individual measurement that makes up the total.
Test it in your trial: pick one line in the exported bill and try to find every measurement behind it on the drawing, without the software open. If you can't, your client can't either.
5. AI that reads the drawing, and lets me check it
AI is genuinely useful in takeoff now, in specific places. Scale is the best example. When Kestrel can't find the scale in the drawing's text, the AI reads it off the title block and offers it to you, and one click applies it. I still check it every time, but having the scale read for me is a real help. It also reads title blocks (drawing number, title, revision and date) and finishes schedules (codes and descriptions), so those don't have to be typed out.
I always check that output. The AI speeds up the reading, but whether the reading is right is still my responsibility, and checking is quick when the result is laid out in front of you.
Where I'd be wary is any takeoff software claiming it can read your drawing, take it off and give you a price with no user input. We're simply not there yet. The accuracy is nowhere near where it would need to be to make claims like that, and a price is exactly the wrong place to find out. There's more on this in our guide to AI in construction estimating.
Test it in your trial: give the AI a drawing you've already measured by hand, and compare. Then look at how easy the software makes it to see what the AI decided and to correct it.
A real example: one takeoff, eight prices
Here's a recent job where those five things mattered. I've left the client and the building out.
The scope was the strip-out of an existing building and the installation of CAT B serviced office space. It covered two separate buildings, delivered over four phases, which made eight zones that each needed their own price. Each zone had its own ceiling heights, floor build-ups and finishes, and all eight had to come out of one takeoff.
In Kestrel, each zone carries its own ceiling height, so wall areas come out right for each zone rather than averaged across the building. On export, the bill came out already split into the correct zones and phases, with a summary and a subtotal for each. That fed straight into a client cost plan of more than 1,000 lines, built on the NRM2 takeoffs, and the bid went in fully submitted and compliant.
The split was the hard part. Doing it afterwards, by hand, across a thousand lines, is exactly the kind of work where mistakes creep in. Having it done on export is the difference. If you want to see what that kind of bill looks like, there's a worked NRM2 bill of quantities example.
What changed in 2026
The biggest change this year is AI, but not where most people are looking. For us it has changed how fast the software itself improves. We use AI-assisted coding, which means improvements and fixes that wouldn't have been possible before can now be done quickly. When a user has a good idea for a tweak or a feature, they often get it the same day.
A recent example. A user had been issued a faulty PDF, where the page dimensions were recorded the wrong way round, and Kestrel exported it in a way nobody expected. It was critical that they issued the takeoff to their client. The fix was made the same day, the update went out overnight, and they issued their takeoffs to the client the next morning.
So my advice for 2026 is to ask how quickly a vendor acts on what users tell it. Ask what was last changed because a user asked for it, and how long that took.
What isn't solved yet
Revisions. When new drawings or new information arrive, I still take off the whole project again and compare it against the first takeoff. That's thorough, but there are definitely efficiencies to be had. We're testing a new revision feature in Kestrel, and expect to release it before the end of 2026. When it arrives, it will be included in the current subscription at no extra cost, not sold as a paid add-on.
A checklist for your next trial
- Export one room and count the edits before you'd send it.
- Measure a real drawing with no tutorial, and time it.
- Find which tier your everyday export lives on, and price that tier.
- Trace one bill line back to every measurement on the drawing.
- Check the AI against a drawing you've measured by hand.
- Split a job into zones and see whether the export keeps the split.
Where Kestrel fits
We built Kestrel™ around those five things, because they're what I needed on live jobs. You measure on the PDF, the measurements stay attached to the drawing they came from, and the export gives you an NRM2 bill of quantities in Excel, split by zone and ready for your rates, alongside the marked-up PDFs your client can trace. It runs on Windows, with a 14-day free trial. No card is needed to start it, and if you don't add one before it ends, the trial simply ends. You can also download Kestrel and run it against the checklist above on your next enquiry.
