Regarding the shell construction and awarding all trades myself, I am currently giving it some thought.
Are pipes and openings for plumbing and electrical work (e.g., through floor/ceiling slabs) usually installed during the shell construction phase? Who normally does this, the shell constructor himself, or do the two trades join in the middle of the shell construction to carry out this work?
Best regards!

There are various ways to handle this. It can be planned in advance at the concrete plant, during bricklaying, while pouring the ceilings, and of course also afterwards with a core drill.
Different trades can be involved each time, and each (plumber, electrician, heating specialist, etc.) may do everything either beforehand or afterwards. It depends on the schedule and coordination.
Of course, it is best to decide everything in advance. However, this is rarely achieved 100% in practice, and additional openings are often necessary here and there later on.

Vicky Pedia2 Jan 2020 14:22Empty conduits (usually PVC pipes) for all utilities are routed outward through the concrete slab and cast into the concrete.
In most cases, precast concrete floor panels (filigree slabs) are used for upper floors. These panels already include large openings prepared at the precast plant. Any additional openings needed for the topping layer must be predetermined, but this is typically managed by the concrete contractor.
For houses with basements, the same principles apply to the ceiling slab above the basement.
Generally, the tradespeople are equipped to create their own openings. However, there should be a clear plan for the routing paths (both horizontal and vertical) before construction begins to avoid crossings, collisions, or unplanned installations.
It should be noted that all ceiling penetrations must be made before insulation is installed, as cables and pipes will be embedded within the insulation or the later screed. Small drill holes (e.g., for downlights) should be made from below the ceiling for more precise work. A coordination meeting among the trades is also helpful; this should be arranged by the site manager before work starts.
