ᐅ Annoying "heating tray" cast into the concrete floor

Hello,
in the living room, in front of the patio door, there is a concrete slab (probably) poured over a length of 460cm (180 inches).
In the basement area, this massive structure is obviously a problem.
What do you think—is there any chance of removing it? The ceiling would no longer be supported at the wall. I’m not sure if a steel beam along the edge would be sufficient. Before I hire a structural engineer, I wanted to get some opinions on whether it might even be worth it.

Also, how much effort does it usually take to remove a 16cm (6 inch) thick concrete slab? Especially, how would one go about it?

Thank you very much!

Structurally, the steel beam must be extended on both sides up to the next wall and supported there, or a bearing must be set into the wall. Unfortunately, I cannot provide any information regarding the costs.

With a height of 2.12 m (7 feet), this is not permitted as living space. What is the point of the effort?

Of course, it can be demolished. Ask a structural engineer how this could be done. Then let us know here. Costs can be estimated once you know what will be built.

Possibly like this: Construction process.
Install formwork (orange)
Create rebar connections with embedded rebar (blue)
Install reinforcement (green)
Pour concrete (red)
After 3 weeks, break out the concrete (yellow)
Plaster the demolition edges.
