Architect misjudges clinker facade area

Hello, that's why no individual contracts. Find a reliable general contractor at a fixed price and that's it. And always remember: can it be a little more (like a butcher). Mistakes also happen in craftsmanship. Always leave a nice buffer.

It depends on the tender text.

For us, it was stated that the contractor must check the quantities and conditions.

In addition, unit prices were agreed upon and then billed according to the measurement.

The quantities from the architect have always been a rough calculation and mostly not accurate.

We never paid more than actually incurred.

Why would we, if the quantity increases, the contractor would not perform this for the original amount.

Right. Prepare bills of quantities with unit prices and done. But here the child has apparently already fallen into the well.

It depends on the tender text. In our case, it said that the contractor has to check the quantities and conditions. In addition, unit prices were agreed upon and then invoiced based on measurement. The quantities from the architect were always a rough calculation and mostly not accurate. We never paid more than what was actually incurred. Why should we? If the quantity increases, the contractor won't do this for the original amount either.

Yes, but sorry, the architect is planning the house! They get good money for it. So 2-3% accuracy per square meter is okay. But really miscalculating is a no-go.

It depends on the tender text.

And probably also on the type of procedure (request for quotation or tender).

Hello, that's why no individual award.

It is unwise to put the award in the same hands as the preparation of the tender documents. Individual award as such is not a fundamental mistake.

Better to plan for too many costs than too few. Because as it was, at least the overall calculation didn't suffer; it might even have eased. How many square meters are we talking about? I mean, in the end the construction company charges according to performance, a few too many ordered pallets of clinker can't have led to the project being aborted? Leave them for the garage, garden house & co. or sell them off on E.-Kleinanzeigen.

I would always be cautious with such stories. Of course, everyone else is always to blame.

PS: we also have 10-20 tons of frost protection material too much on the construction site that we have to pay for due to a slight overestimation by the general contractor. But I prefer it this way around rather than the other way and a surprising additional charge along the lines of: we need more, otherwise it can't go on, costs xxxx€. Take it or leave it.
