Construction costs are currently skyrocketing

Would be just under €140 per linear meter. Don’t find that excessively expensive. Pure steel railing (flat) here in BW about €350-400 per linear meter

Just a question about construction costs. I still need to model the terrain in the garden. Various earth mounds into a small embankment at the boundary, dig out the crane area and place it under the terrace, plus a bit more gravel where the carport will go. I have an offer here for 1 day with a 5t excavator, driver, and vibrating plate for just over €1600 gross without gravel. Is that fair?

We paid 700 EUR net per day for excavator and driver and 30/h for 1 construction helper. They then shaped the terrain (processed construction road as a substructure for the entrance and spread some earth). But it was only a mini excavator, I estimate 2t...

Insofar, your price actually seems fair to me, if no construction helper costs are added...

Does anyone know current prices for precast concrete ceiling elements? Span 6m for garage roof.

Ok, thanks. I also had the feeling that it’s reasonable. I’ll probably go for it – also due to a lack of alternatives..

Honestly, the price surprises me. Most of your Google results cost over 200 EUR per meter. And that doesn't even include material for the foundation or paying a worker. PS: Your first image hit "Florenz" costs 560 EUR for a 2m piece...
