Hi,
I am planning to demolish walls in the basement to increase the garage space from 25.5 to 50 sqm.
I sent a request to a building consultant:
1. Are the walls load-bearing?
2. What measures are needed to replace the walls if necessary? Beam and/or pillar?
Received a response today:
The time to investigate was set to 18 hours. Of course, a solution proposal would be given then.
The total price would be 16,875 SEK
(750 SEK/hour + VAT)
Feels like it might be a bit expensive?
So now I'm asking here instead:
Are the walls load-bearing, or can the concrete slab be self-supporting?
There is a clever drawing specifically of the reinforcement.
What dimension of beam in the ceiling is needed then?
Is it necessary to have a pillar right under the beam?
DRAWINGS ARE HERE
OR HERE IF THE LINK ABOVE DOES NOT WORK

It is quite a complex construction you desire.
I think the constructor's quote seems reasonable.
Possibly, it might be cheaper if you take it on a running account instead?

Yes, exactly. It's because they are load-bearing that the designer has drawn them in. But I can also see it on the reinforcement. You can see that the bottom reinforcement is spliced over support. Then there's extra top reinforcement placed over the walls. This is to "absorb" tensile forces that arise when the slab is loaded.
If I remember correctly, there are at least two beams that need to be dimensioned, as well as some columns.
If you have requested a fixed price, the consultant must account for unforeseen problems during the work.
Do you think I might have managed in less time?
But you definitely have to spend time checking that the drawings are accurate.
The hours can easily add up.

There is no doubt that all the walls you want to remove are load-bearing.
Whether 18 hours is a lot or a little is probably a question of what you would be getting. For just dimensions, it's a lot, but if it were complete drawings with descriptions of execution, it's reasonable. The calculation itself takes maybe a few hours, but the drawings take some time.
