Construction Quantity Takeoff: How to Replace Excel with OneEstimate [Video Tutorial]

What is a Quantity Takeoff (Memoria de Cálculo)?

A Quantity Takeoff is the technical document that backs every quantity in your construction budget. It shows the mathematical calculations behind each line item: how many m² of wall, how many m³ of concrete, how many kg of steel.

In public tenders across Mexico, Colombia, Chile, and Peru, it's a mandatory requirement. Yet most professionals still do it in Excel, wasting hours on manual formulas.

Why Excel Falls Short

Manual formulas that break when you copy cells

No link to budget — change a quantity and you have to update both files

No unit recognition — you manage m², m³, kg all the same way

Error-prone — one wrong cell reference cascades everywhere
