Bill of Quantities
Bill of Quantities (BoQ).
What isn’t measured can’t be controlled. And what isn’t controlled… spirals out of hand.
What is a Bill of Quantities?
A BoQ is a technical document listing all work items executed or to be executed, together with their quantities.
It’s the essential tool to know what has been done, how much has been done, and what it really costs.
It enables rigorous, objective cost control throughout the project.
It’s the basis for issuing payment certificates, substantiating invoices, and validating actual progress on site.
Bill of Quantities
What does a BoQ include?
- Breakdown by work sections/trades (structure, masonry, MEP installations, finishes, etc.).
- Exact, justified measurement of each executed item.
- Comparison between the designed scope and the as-built work.
- Cost summary by sections.
- Basis for preparing payment certificates/interim valuations.

Who needs this service?
- Contractors, to substantiate invoicing and demonstrate real progress to developers.
- Contract Administrators / Design Team, to validate quantities and verify compliance with the project.
- Private clients and developers seeking real, documented control of cost and progress.
Why is it indispensable?
Because without real measurements, there’s no objective way to know what has been executed.
Because it prevents conflicts and misunderstandings between developer and contractor.
Because it allows early detection of budget deviations.
Because it’s the only solid basis for certifying payments with safety and transparency.

Key benefits:
- Real cost control on site.
- Transparent invoicing.
- Objective technical justification for clients, developers, or institutions.
- Prevention of errors or non-executed works being billed.
A BoQ isn’t a decorative document:
it’s the economic and technical X-ray of your project.
Because what isn’t properly measured…
ends up overpaid—and argued about later.
