The software for quantity surveyors, from take-off to bid comparison
For the quantity surveyor, BuildOS connects take-off, pricing breakdown, budget and bid comparison around one single dataset: the 3D model feeds the quantities, the pricing breakdown stays synced with the specification, and received bids come back genuinely comparable — with no re-entry.
Request accessThe quantity surveyor's daily reality
Take-off in Excel, prices in another file, a pricing breakdown to reconcile with the specification, contractor bids to compare by hand: the quantity surveyor spends most of their time moving figures between tools that don't talk to each other.
Every time the project changes, the take-off has to be redone, the pricing breakdown regenerated, the budget readjusted — each one a chance for documents to drift apart and for errors that only surface at bid opening.
What BuildOS changes for you
- A reliable take-off from the native 3D model: areas and volumes are computed as the project is modelled, rather than entered by hand.
- A pricing breakdown linked to the take-off and synced with the specification: the description and the priced breakdown share the same dataset, with no manual reconciliation.
- A price book that builds up your unit prices, project after project, to save time from one job to the next.
- A forecast budget per lot built on the take-off quantities: design budget, works budget and total cost of ownership (TCO).
- A comparison of received bids on scope: gap to budget, omissions and best value, for genuinely comparable offers.
From take-off to comparison, with no re-entry
You enter the project once: the data flows from the model to the take-off, the pricing breakdown and the budget, then to contractor consultation and bid comparison. When the project evolves, quantities recompute and the pricing breakdown and budget realign.
The result: a pricing breakdown and budget consistent with the package, ready to send out for consultation, and received bids you compare on the same scope, from brief to site.
Frequently asked questions
Where do the take-off quantities come from?
Areas and volumes come from the native 3D model: they are computed as the project is modelled. You confirm or adjust the suggested quantities, and you can add lines specific to each package.
Is the pricing breakdown synced with the specification?
Yes. In BuildOS, the specification describes the works and the pricing breakdown prices them: both share the same dataset, fed by the take-off, with no manual reconciliation.
How do you get genuinely comparable bids?
You send the pricing breakdown out for consultation, then the comparison analyses the bids received on the same scope: gap to budget, omissions and best value, lot by lot.
