Construction costs are currently skyrocketing

Currently in all media:

On German construction sites, prices have risen as fast as they have not for more than 50 years. According to the Federal Statistical Office, in May the prices for construction services including VAT were 17.6 percent higher than a year before. This was the highest increase since May 1970, when they had risen by 18.9 percent over the year, the agency reported on Friday. In the previous reporting month, February 2022, the increase was 14.3 percent.

Reasons are scarce and expensive materials as well as high demand. The price increase was especially strong for metal construction work (+23.6 percent) and concrete work (+23 percent). Below-average increases were recorded for earthworks (+14.8 percent) and masonry work (+12.8 percent).

Also very enlightening is the view over the last 10 years

I never know whether I should keep complaining or be happy that I am still even able to build (have built) a house :rolleyes:

I did it myself again and gave more air where I need it, and then it was quiet and the air exchange is now 0.3 more than sufficient.

What did you use to carry out the measurement yourself? Were you able to borrow the device somewhere or ...?

I never know whether I should keep complaining or be happy that I am still able to build (have built) a house at all :rolleyes:

I am still waiting until 1. the house is finished and 2. also at the agreed price. With things like this, I always get a bit scared that at some point the general contractor will invoke §313. But if all this works out, we have actually just managed to complete the house before the window closed for now.

How do you mean with the sensor?

There are so-called VOC sensors (see search engine) or corresponding products that constantly monitor and display the indoor air quality. For a few years now, for example, I have had the Netatmo indoor air sensor (with HomeKit integration), which I currently have in the new house in the attic... In all rooms of the house, I have Bosch Twinguards hanging (also HomeKit), which function as smoke detectors and simultaneously display room temperature, humidity, and air quality. You can very well monitor the air quality or see how it changes as soon as people are present in the room. How much it worsens at night in the bedroom, for example, or how quickly it settles back to the optimum after getting up and running controlled residential ventilation...

I am still waiting until 1. the house is finished and 2. also at the agreed price. With such things, I always get a bit scared that at some point the general contractor will come around with §313. But if everything works out like this, we actually just managed to finish the house construction before the window first closed.

I completely block out both cases, partly because I have no control over it and partly because I would certainly sleep worse if I worried about it. I am anything but gullible, but right now I have to have trust in the general contractor and the project. I really agree with you there, but I will only start to worry when the time comes :D Besides, I checked the contract from our general contractor, clause by clause, and there was so much nonsense in it that has no place in a construction contract, I’m sure they don’t have a Building Code in their office (yes, I’m sugarcoating it :p)

Contract and trust are all well and good, but if it is no longer economically feasible, it doesn't help. It’s like with gas. If someone at the start of the chain has to work uneconomically, it affects everyone behind in the medium term. Either through bankruptcy or price adjustments. In case of bankruptcy, usually both. And you don't even have to have a building code yourself if the Chamber of Crafts publishes the first articles in its member magazine about how to enforce prices ;)
