We take off the project item by item, price it with unit rates and track the budget against actual cost throughout the work.
Illustrative imageQuantity take-off means measuring the quantity of every work item from the drawings: how many cubic metres of concrete, tonnes of reinforcement, square metres of finishes, how many doors. Multiplying these quantities by unit rates gives the bill of quantities (BOQ). Cost management means tracking this budget against actual cost throughout the work.
A well-prepared take-off lets you compare bids on the same scope, tie payments to work done and avoid disputes over variations. DEMAFT always prepares its quotes item by item, with quantities and unit prices.
Lump-sum bids where no one knows what is included and what is not.
Bids that cannot be compared because they rest on different scopes.
Payments that cannot be tied to the actual quantity of work done.
Budget overruns noticed only when the work is finished.
Disputes over which item a variation belongs to.
Quantities are taken off the architectural and structural designs and, if needed, measured on site. Each item is listed with its description, unit and quantity; unit rates are set with their material, labour and equipment components in mind. The estimate and the quote are thus built on the same item list.
During execution the quantity of work done is measured against this list; interim payments are prepared from the actual quantities, and the budget is regularly compared with actual cost. If the scope changes, the new item is defined and priced separately.

Comparing actual quantities and cost with the budget.
Every DEMAFT quote defines the scope item by item, with quantities and unit prices; the programme and payment plan are part of the quote. Item-by-item quantities and reporting are the basis of our transparency principle: we want our clients to know at every stage what they are paying for and where the work stands.
We have applied this approach at very different scales, from 7,116 mass and social housing units to a stadium complex and the finishing works of a single villa. If you are building a villa in Türkiye, you can also see an approximate cost range with villamaliyeti.com (in Turkish), which uses DEMAFT’s cost database.
The take-off is the quantity of each work item. The bill of quantities (BOQ) lists those quantities with unit rates and gives the total cost.
A lump sum gives one total price for the work; with unit rates each item’s quantity and rate are listed and payment follows the quantity done. An itemised quote keeps the scope clear in both cases.
Yes. DEMAFT’s free tool villamaliyeti.com (in Turkish) takes off the quantities automatically from the plot, floors, rooms and quality level and gives a cost range. The firm price comes from a quote with quantities.
