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?

He said that according to VOB, doors and windows under 2.5 sqm (27 sq ft) are not deducted. The additional effort compared to fully building up the wall, to place these openings precisely at certain points, is only justified for larger openings by the saved material. I consider this a practical and fair approach to reflect this as a flat rate in the cost calculation.

With Excel, it’s only a few clicks. When laying bricks or blocks, the stop-and-go process is a bit more inconvenient.

There was no tender. I went directly to the general contractor and gave him the floor plan as I envisioned it, and after a few meetings, he prepared an offer.If you approached a general contractor, why are you interested in their quantity calculation? You are signing a fixed-price contract, right? Then the only thing that matters for you is the final amount. You compare that with the next offer.
