Construction of a 144 sqm bungalow in Fichtenwalde (near Potsdam)

Please use the correct units. A device with a power consumption of 0.7 kW has an energy demand of 0.7 kW x 24 h = 16.8 kWh in 24 hours. ;)

Yes. It is known. 16.8 x 6 is 100 kW. At 0.35 cents / kW, that is 35 € per day....

Speak to the GU about that. He will probably insist on that for warranty reasons.

Keeping the construction site in a warranty-compliant condition is in the interest of the GU - so why is the client himself the drying equipment attendant here?

The electricity consumption usually now goes through the client anyway. There would probably be communication complications if one party interested wants to use consumption-intensive devices and the other prefers powerful devices. On top of that comes the twice-daily maintenance… this can become very expensive if the construction company is not local. So it is a location-dependent service that can be well assigned to the client. There are roughly about 20 such positions in the contract, just to give a rough estimate. If all of them ran through the GU, about 30% fewer people could afford to build a house, roughly speaking. Or you just offer it as a subcontractor (BT) right away… mind you: there are self-performed tasks by the GU that they gladly do because they can manage or outsource the costs for these tasks very well themselves… because the position would be comparatively overpriced if done by the GU. Apart from that, the time pressure is actually more on the client… the GU would have a little breather during the drying phase. I think a fundamental debate about “why doesn’t a GU cover all costs?” is unnecessary.

Because that is agreed upon in the contract. And it is probably much cheaper for me than if the general contractor sends a worker to the construction site three times a day. Including travel to and from the site, I would have to pay for a full-time worker for 4 weeks.

I just checked the electricity consumption. The construction dryer and the display program use 200 kWh in 24 hours. That’s about 70 €. I have budgeted 2,000 € for construction electricity in the additional construction costs. So it should roughly add up :-)
