BOQ cross-check: is the bill of quantities commercially sound?
A commercial and quantity-plausibility review of a construction bill of quantities — arithmetic, omissions, duplicates, quantity norms and rate outliers — performed by Buildraa, reached through DevPartner.
A feasibility answers whether a development works. A bill of quantities decides whether the cost you carried into that feasibility is the cost you will actually pay. The two questions are related, and they are owned by different products: DevPartner runs the feasibility, Buildraa reviews the construction cost.
What the cross-check looks at
- Arithmetic: quantity × rate, subtotals, taxes, grand total, rounding and duplicate totals.
- Quantity plausibility against the built-up area — concrete, reinforcement, blockwork, plaster, flooring, finishes, waterproofing, joinery, plumbing, electrical and external works.
- Omissions: missing trades, preliminaries, testing and commissioning, statutory items and provisional sums.
- Commercial risk: duplicate line items, unpriced items, inconsistent unit rates, inconsistent tax treatment, unclear exclusions and specification mismatches.
- Rate basis: the city, the pricing date, the specification level and whether escalation has been considered.
Current status of the automated service
Automated upload is not available on this deployment.
The governed Buildraa cross-check contract is not yet activated here, so there is no upload form on this page. DevPartner will not duplicate Buildraa's BOQ engine to produce a result that would not match the reviewed one. Request a review and a construction cost reviewer will take the file directly.

How your file is handled
- A bill of quantities you send is treated as confidential commercial information.
- It is never used as public training data and is never published or benchmarked publicly.
- Access is restricted to the reviewer handling your project, and you can ask for deletion at any time.
- See the privacy notice for retention and deletion.
Frequently asked questions
- Who performs the BOQ cross-check?
- Buildraa, the House of Alpha construction product, owns bill-of-quantities normalisation, arithmetic checking, quantity plausibility and rate benchmarking. DevPartner does not re-implement those calculations; it is the entry point that routes a site to the people and the service that do.
- Can I upload a BOQ right now?
- Not yet. The governed Buildraa cross-check contract is not activated for this deployment, so no automated upload is offered. Offering an upload that silently does nothing, or producing a check from a duplicated formula set, would be worse than saying so plainly.
- What happens when I request a review?
- Your enquiry is recorded durably with the site context and routed to a construction cost reviewer. You will be told what is needed — the BOQ file, the drawing set, the specification level and the city and date the rates were priced on.
- Is this a substitute for a quantity surveyor?
- No. It is a commercial and quantity-plausibility cross-check that flags arithmetic errors, omissions, duplicates and outliers. Measurement certification, structural adequacy and statutory compliance remain with your appointed consultants.
