What is a "mounting pit for temporary construction"?

Hello dear community,

we have registered with you today and are already sure that we will receive valuable advice and tips through this forum.

We are building (after years of arduous searching for an affordable, beautiful plot) in the so-called Pfaffenwinkel in Upper Bavaria. South-facing slope with 770 sqm. Really something to dream about and be happy about.

Currently, we are struggling with several obstacles. On the one hand, there is very poor communication with the developer and his site manager (they are almost never reachable by phone, email, or SMS). On the other hand, we have just found out that a fairly large tree on our property must be cut down because its crown would collide with the roof structure. The site manager could have recognized this months ago. However, the Lower Nature Conservation Authority is now obstructing the felling...

But to the actual topic:

Could you please tell us what the above mentioned mounting pit is about? We have ordered a construction power box ("Provisorium") from the local construction power supplier, and now they expect us to have a standardized mounting pit excavated at our own expense. Our developer has "never heard of this."

Thanks and many first greetings from the building owner team

Why don't you ask the supplier? Better to ask a silly question once than to be uncertain for days and let time slip away again.

The cable end from the supplier must be securely connected to the cable end of the construction power box. There are two options for this. Either you dig a hole, expose their cable end, then connect the construction power box and afterward refill the pit. This way, the connection point is protected from tampering. Later, dig it up again to establish the house connection. Or you have their cable exposed and connect the cables via a connection pillar, which someone has to provide.

Because I am reading the problem with the tree. There is an interesting topic here where the house had to be planned because of an old oak so that the oak had to be more or less integrated into the project.

The site manager should have recognized that months ago.

Not the client team?

The cable end from the utility provider must be securely connected to the cable end of the construction power box.

Correct. Civil engineering for utility lines and construction power must be provided by the client. You can do this yourselves or pay your construction company to do it. However, you as the "client team" cannot avoid taking care of certain things yourselves / educating yourselves. Especially regarding the house connections.
