The short version
- Each has a real cost: B2W Estimate pricing is not published anywhere, and the quote depends on estimator seats plus which of the four other B2W modules you take, so like-for-like comparison with HeavyBid or spreadsheets is impossible without going through a sales cycle; Propeller Aero platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
- They diverge on capability: B2W Estimate covers Production-rate estimating, Propeller Aero covers Photogrammetric processing.
- Prices and features above were last checked on 1 September 2026.

What people use each for
The jobs each tool is most often brought in to do.
B2W Estimate
- A grading contractor bids a 40 million dollar DOT job and needs to test three crew configurations against the same quantities before the bid deadlinenot Propeller Aero

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
B2W Estimate
- Pricing is not published anywhere, and the quote depends on estimator seats plus which of the four other B2W modules you take, so like-for-like comparison with HeavyBid or spreadsheets is impossible without going through a sales cycle
- The system is worthless until your own crews, equipment and production rates are loaded, which is typically several months of a senior estimator's time before the first bid comes out
- It is aimed squarely at heavy civil self-performing work, so a general contractor whose bids are mostly subcontractor quotes gets very little from the production-rate engine
- The Trimble acquisition means the product now competes internally with other Trimble civil estimating assets, and buyers should ask directly about the long term roadmap for overlapping products before signing a multi-year term
- Reporting outside the Inform module is limited, so organisations that want bid analytics across years typically end up buying another module or extracting to a warehouse
Propeller Aero
- Platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
- The corrections network is free only while you hold a current platform licence, so cancelling the platform subscription reintroduces a 1,000 dollar per year per group hardware cost that many buyers do not model
- AeroPoints are a hardware purchase at 1,000 dollars each and most sites need several, so the true entry cost includes several thousand dollars of equipment on top of a subscription
- It measures rather than designs, so a contractor still needs Civil 3D, Trimble Business Center or an equivalent to produce and revise the design surfaces the measurement is compared against
- Accuracy depends on flight planning, ground control placement and weather, and a poorly flown survey produces a confident wrong volume, so an organisation still needs someone who understands survey error rather than only a drone pilot

Questions people ask
- Is B2W Estimate or Propeller Aero better?
- Neither clearly leads. B2W Estimate starts at On request and Propeller Aero at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, B2W Estimate or Propeller Aero?
- B2W Estimate starts at On request and Propeller Aero at On request.
- Does B2W Estimate or Propeller Aero run on more platforms?
- B2W Estimate runs on Windows, Web. Propeller Aero runs on Web, iOS, Android.
- What is B2W Estimate best used for?
- B2W Estimate is most often used for a grading contractor bids a 40 million dollar dot job and needs to test three crew configurations against the same quantities before the bid deadline, a utility contractor wants the production rates used in the winning bid pushed into field logging so the superintendent is measured against the estimate, an estimating department with four estimators needs several people working on separate sections of one bid without merging spreadsheets by hand, a contractor moving off heavybid wants a resource database it can reuse across estimating, dispatch and fleet maintenance. Of those, a grading contractor bids a 40 million dollar dot job and needs to test three crew configurations against the same quantities before the bid deadline and a utility contractor wants the production rates used in the winning bid pushed into field logging so the superintendent is measured against the estimate are not what Propeller Aero is typically brought in for.
- What can B2W Estimate do that Propeller Aero cannot?
- B2W Estimate covers Production-rate estimating, Central resource database, Concurrent bidding, DOT bid file export. Propeller Aero covers Photogrammetric processing, AeroPoints ground control, Volume measurement, Design surface comparison.
Answered from the vendors’ own pages
B2W Estimate: Is B2W Estimate still sold under its own name?
Yes. Trimble acquired B2W in 2022 and continues to sell it as B2W Estimate within the Trimble Construction portfolio.
Propeller Aero: How much does Propeller cost?
The platform is quoted and not published. AeroPoints are 1,000 US dollars each, with the corrections network included for twelve months and thereafter free while a platform licence is current, otherwise 1,000 dollars a year per group.
B2W Estimate: Is there a perpetual licence?
Current sales are subscription based. Existing perpetual customers have been migrated toward subscription, so treat a perpetual arrangement as something to negotiate rather than assume.
Propeller Aero: Do I need AeroPoints?
No, you can use conventional surveyed ground control, but the AeroPoints workflow is the main reason contractors choose Propeller over generic photogrammetry.
B2W Estimate: How does it compare with HeavyBid?
Both are production-rate estimators for heavy civil. B2W's argument is the shared resource database across estimating, field tracking, dispatch and maintenance; HeavyBid's is depth of bidding features and a large installed base in highway work.
Propeller Aero: Is it survey grade?
Propeller states centimetre-level accuracy with correct ground control. Whether that satisfies a contract depends on your specification and on how the survey was flown, not on the software alone.
B2W Estimate: Does it work for building construction?
Poorly. It assumes self-performed work priced by crew output. Vertical builders bidding mostly subcontracted scopes should look elsewhere.
Propeller Aero: Who owns the data?
You retain your survey data and can export surfaces and point clouds, but check the export formats and retention terms in your contract before closeout, because bulk historical export is not a self-service one-click operation.
