Separate quantity takeoff from a priced estimate
A takeoff answers how much work is shown in the documents: counts, lengths, areas, or volumes, with units and sheet references. An estimate adds material quotes, labor production assumptions, equipment, indirect costs, and the bid scope. A correct count with the wrong assembly, unit, or labor rate can still produce a poor estimate.
Start with a sheet register and revision date. State which disciplines, alternates, demolition, temporary work, and drawing schedules are included. A wall length on a plan is not automatically its finished area; a symbol count is not proof that all scheduled equipment is shown on the selected sheets.
PlanSwift, Bluebeam, STACK, and CyanBuild: compare the documented workflows
PlanSwift combines Windows desktop takeoff and estimating with manual tools and Takeoff BOOST AI assistance. Its Auto Takeoff documentation describes generating draft quantities for review; the feature is included in Core. Check the current plan details for access and terms. Calling PlanSwift manual-only would omit these tools.
Bluebeam Revu provides PDF measurement and reusable markup tools. Quantity Link transfers measurement totals into Excel and is available with Complete or Max. Tool Chest supports saved, shared tool sets. Evaluate these capabilities against your existing estimating workbook instead of assuming there is no connection to estimating.
STACK provides browser-based takeoff and estimating. Its documented AI takeoff tools include assisted counts, walls, and areas with editable output. The separate STACK Assist document assistant answers questions about plans. Ask the vendor which functions your subscription includes; a document-answering feature and automated measurement are different tasks.
CyanBuild generates draft quantities from PDF plans for review and adjustment. Verify detected items against the drawings, correct omissions or extra detections, and confirm the rates and scope used in your estimate. This comparison does not establish that one tool is faster or more accurate than another on your plans.
Run a comparison you can reproduce
- Choose a representative set of sheets, record the revision, and use the same scope in every tool.
- Calibrate known dimensions and check units before measuring. Identify details and viewports that use a different scale.
- Create an independently reviewed quantity reference. Keep disagreements and unresolved scope items visible.
- Check both omissions and extra counts. For lengths, areas, and volumes, record the deviation and its cause instead of reducing different measurement types to one accuracy percentage.
- Measure total effort: setup, processing, corrections, specification review, and export. Repeat on a second drawing style before generalizing.
- Confirm that the output preserves units, source references, and revision context in the estimating workflow you actually use.
Keep a review record for each quantity
A useful review record contains the item or assembly, drawing and detail reference, unit, measured quantity, reviewer, and any assumptions. Reconcile counts with schedules, exclude duplicated details, and document alternates separately. If the drawings and specifications disagree, carry an explicit clarification rather than silently choosing a number.
These checks apply to paper measurement, point-and-click tools, and AI output. Software can assist with repetitive work; an unreviewed result is not a complete bid.
Budget for the whole workflow
Compare subscription or license cost together with setup, training, review, corrections, and export work. Use your own measured hours and loaded staff cost for the comparison. Published vendor demonstrations and hypothetical time savings are not a guarantee for your project.
Free includes 3 PDF pages per month. Paid monthly plans are Starter $29 for 30 pages, Pro $99 for 120 pages, and Enterprise $299 for 400 pages. Review current plan features and terms on the pricing page.

Frequently Asked Questions
Does PlanSwift still require every quantity to be measured manually?
PlanSwift offers manual measurement tools and Takeoff BOOST AI assistance, including Auto Takeoff in its Core plan. Feature access depends on the subscription. Check the current vendor documentation and review generated quantities before pricing them.
How should I compare takeoff software on a real project?
Use the same drawing revision, sheets, measurement rules, and scope in each tool. Compare checked quantities with an estimator-reviewed reference, record missed and extra items, and include setup and correction time. Keep pricing and bid preparation separate from quantity extraction.
Can AI takeoff handle a complex commercial plan set?
Test representative sheets from your own discipline and drawing style. Complexity, scan quality, scale, schedules, and repeated details affect the review needed. A successful sample is useful evidence for that sample; it does not guarantee complete quantities across an unchecked plan set.
What should I do if an AI takeoff is wrong?
Check the source sheet and scale, correct the quantity or classification, and record the reason. Inspect both missing items and extra detections. Reconcile the reviewed quantities with schedules and specifications before using them in an estimate.
Will switching software automatically save estimating time?
Time savings depend on the project and the full workflow. Measure upload and setup, automated processing, manual corrections, scope review, and export time together. A short automated processing step alone does not establish a faster completed estimate.
