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; Buildots tracking depends on a BIM model maintained at construction level of detail; on a job where the model is stale or was never built for coordination, the comparison degrades and much of the value disappears.
  • They diverge on capability: B2W Estimate covers Production-rate estimating, Buildots covers Hard hat 360 capture.
  • 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 utility contractor wants the production rates used in the winning bid pushed into field logging so the superintendent is measured against the estimatenot Buildots
  • An estimating department with four estimators needs several people working on separate sections of one bid without merging spreadsheets by handnot Buildots
  • A contractor moving off HeavyBid wants a resource database it can reuse across estimating, dispatch and fleet maintenancenot Buildots

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

Buildots

  • Tracking depends on a BIM model maintained at construction level of detail; on a job where the model is stale or was never built for coordination, the comparison degrades and much of the value disappears.
  • The data only arrives if someone walks the site every week with the camera, so coverage decays quietly when the site team is under pressure, exactly when the reporting is most needed.
  • Pricing is per project rather than per seat and includes hardware, so a contractor cannot roll it out cheaply across a portfolio of small jobs and it is uneconomic below a certain project value.
  • It reads interior fit-out and repetitive vertical work far better than structure, groundworks or external envelope, so a large fraction of a project's programme is outside what it can score.
  • Making progress objective creates commercial friction with subcontractors whose valuations have historically been negotiated, and contractors who deploy it without addressing that in the subcontract get pushback rather than adoption.

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.

Buildots: What does Buildots cost?

It is quoted per project based on size, duration and scope, with camera hardware included. Nothing is published.

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.

Buildots: Do I need a BIM model?

Yes. The system scores progress by comparing captured conditions against model objects, so the model quality sets the ceiling on accuracy.

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.

Buildots: What kind of projects suit it?

Repetitive vertical work with heavy interior fit-out. Civil, groundworks and external envelope are poorly covered.

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.

Buildots: Who does the site walks?

Your own site team, typically once or twice a week. There is no Buildots operator on site.
