We are planning to install a satellite system and want to keep the option open for a photovoltaic system. Our general contractor (GC) has offered a price of 450€ per empty conduit, with two conduits proposed for installation in the utility shaft. For your information: Our house has a basement, two full floors, and one attic floor. The total building height is just under 13 m (43 feet). The following questions come to mind:
a) Is the offer a bit excessive for installing “just” one conduit in a shaft that is already planned?
b) Are two conduits really necessary? Could both cables not be routed through a single conduit?
c) Should I possibly reject the offer and negotiate directly with the electrician during construction, potentially at a lower cost? The satellite system is currently not included in the house contract and, according to the GC, will be arranged later between the homeowner and the electrician.

We paid 120 euros for two pipes. We ordered them exactly as you did. I also think the price is quite steep.

For the photovoltaic system, an empty conduit with a diameter of 25mm or 30mm (1 inch or 1.2 inches) is sufficient. For the satellite system, I would be more cautious. Four cables or a quad cable are quite tight in a 32mm (1.3 inch) conduit. However, for 450 euros, I would expect a premium installation.

Just drive to the hardware store, buy a 50m (160 ft) roll of DN 40 conduit, and install it yourself inside the house, provided you have access to the shell construction.

Without knowing the construction site, it’s not possible to give a definite answer. However, in my opinion, that would be far too expensive.
If you’re reasonably handy, do it yourself. If there is enough space, simply install two PVC pipes in the shaft and, for convenience, pull a draw wire through them directly.

Pay attention to the spacing.
The grounding cable must not be routed directly next to other cables.
The longer the cable, the further away it should be from the others.
Consult an electrician.
