Side note: It’s quite an achievement these days for a construction company to go bankrupt. That’s something you have to manage first...

Isn’t the big wave of insolvencies finally clearing up? Starting this month, filings have to be done normally again. The Federal Statistical Office has already identified a huge backlog compared to the previous year without COVID.

It is not difficult for a construction company to go bankrupt.

Yes, the veil is lifting. This is also the case for many private individuals.

You are right… This is not skill but stupidity.

If I go bankrupt despite an almost endless amount of work, and that after 20 years of self-employment, by then a reasonable financial cushion should have been built up. Then the advance work with regular milestone payments is also justifiable (for me it was between 7,000-15,000 euros) in case a client fails to pay.

Besides, most companies are usually happy to be overcharged.

Especially in times of oversupply, there is a risk. Too rapid and excessive growth is a danger, and there is a lot of money involved. If customers then fail to pay, everything collapses. It only takes one large project to bring everything down.

Thank you for your report. I sometimes see myself in that.
Is the flat roof of the garage completely flat with 0% slope?
Often, the cause of insolvency is also the payment behavior of the customers.
Looking forward to more pictures.

Hello builder,
Could you give me approximate quantities of how much concrete and masonry were used in your build, in cubic meters?
Your shell construction price is quite low, and I want to check something. I know you have other concerns at the moment.
Best regards
