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; Topcon MAGNET mAGNET is built around Topcon and Sokkia hardware, so a firm running mixed instrument brands will not get the field workflows it expects and is better served by manufacturer-independent field software.
  • They diverge on capability: B2W Estimate covers Production-rate estimating, Topcon MAGNET covers MAGNET Field.
  • 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 Topcon MAGNET
  • A utility contractor wants the production rates used in the winning bid pushed into field logging so the superintendent is measured against the estimatenot Topcon MAGNET
  • An estimating department with four estimators needs several people working on separate sections of one bid without merging spreadsheets by handnot Topcon MAGNET
  • A contractor moving off HeavyBid wants a resource database it can reuse across estimating, dispatch and fleet maintenancenot Topcon MAGNET

Topcon MAGNET

  • A civil contractor running Topcon grade control that needs design models prepared and pushed to machines from one environmentnot B2W Estimate
  • A survey crew doing construction layout with Topcon total stations and wanting field data to reach the office without a memory cardnot B2W Estimate
  • An earthworks estimator producing takeoff quantities and mass haul plans from engineering drawingsnot B2W Estimate
  • A firm standardising on one manufacturer end to end to reduce the number of software packages its crews have to learnnot B2W Estimate

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

Topcon MAGNET

  • MAGNET is built around Topcon and Sokkia hardware, so a firm running mixed instrument brands will not get the field workflows it expects and is better served by manufacturer-independent field software.
  • Topcon does not publish a rate card and sells through dealers, so two customers can pay materially different prices for the same licences depending on region and negotiation.
  • Cloud connectivity through MAGNET Enterprise is commonly bundled for the first year and then charged, which surprises firms that budgeted only for the licence.
  • Office capability is spread across modules and disciplines rather than sold as one product, so getting from data collection to machine control model preparation can require more than one purchase.
  • The office desktop software is Windows only and the wider line has been reorganised more than once, so buyers should confirm which specific product name their dealer is quoting and how long it will be supported.

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 Topcon MAGNET is typically brought in for.

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.

Topcon MAGNET: Does MAGNET work with Trimble or Leica instruments?

Not as a practical daily workflow. It exchanges standard file formats but the field software is designed for Topcon and Sokkia hardware.

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.

Topcon MAGNET: Is pricing published?

No. MAGNET is sold through Topcon dealers with quotes varying by region and configuration.

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.

Topcon MAGNET: Is the cloud service included?

Typically for a first year with a licence, then renewable as a paid subscription.

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.

Topcon MAGNET: Can I get my data out at project closeout?

Yes, through LandXML, DXF and standard survey exchange formats, though field-specific configuration does not transfer to a competitor.
