Quantity take-off and bill of quantities (BOQ)
OnePoint BIM takes quantities from the BIM model or from drawings and prepares the bill of quantities (BOQ), or fills the one the project uses. This is what 5D BIM means in practice: model elements linked to quantities and cost data.
What you receive
- Quantities by element, zone and floor, from the model or drawings.
- The project’s BOQ filled in its own format.
- BOQ items written when the tender documents have none.
- MEP quantities: ducts, pipes, cables, fittings and equipment.
- Support for the pricing team in cost estimating.
When it is used
At tender stage
Quantities that pricing can rely on, within the tender period.
Before signing
Independent quantities to compare with the tender BOQ.
Material orders
Quantities by zone and floor for procurement.
After a design change
The difference in quantities between one issue and the next.

Common questions
How does quantity take-off relate to 5D BIM?
5D adds cost to the BIM model. In practice, quantities are taken straight from the model elements and linked to the BOQ items, so they are updated with each design change.
Can quantities be taken from an existing Revit model?
Yes. The model is sent with the BOQ or the required measurement method, and the offer states which items are measured from the model.
Which measurement method is used?
The one set in the contract or the BOQ. We follow the project’s measurement method, so the quantities go straight into the BOQ.
