Hello everyone,
I have a quote from a contractor. Under the masonry section, there is a quantity X in m³ (cubic meters), which is multiplied by the unit price per m³ for calcium silicate bricks to get the total price for the masonry work.
So far, so good.
However, when I go through the floor plan and add up the m³, I do not reach the quantity X.
I have a total of four masonry items that deviate by 29%, 12%, 12%, and 10%.
I assume that some waste allowance is included, either through the unit price or the quantity. But 10% seems quite high to me. I would have thought about 3% or at most 5%.
Is there anyone in the industry or with experience on how this is usually handled?

There are two points where you might have made measuring errors:
1) Room height: here you overlooked the difference between "finished height" and "rough height."
2) Wall openings: you subtracted all openings, although some should be measured additionally.

Yes, the interior walls are 11.5 cm (4.5 inches) and 17.5 cm (7 inches), the exterior walls are 20 cm (8 inches), and there is an intermediate wall to the garage measuring 36.5 cm (14.4 inches).
I used the rough dimensions, not just from the finished floor level.
I think this is what you mean by measuring over.
According to the VOB, doors and windows under 2.5 sqm (27 sq ft) are not deducted. So, I’m paying €4500 for the windows and doors.
It’s even more extreme on the upper floor. That’s where the 11.5 cm (4.5 inches) walls are installed. Doors account for nearly 30% there.
I’ll have to double-check later to see if that’s really the only reason. In Excel, it’s just a few clicks.
