Architect-1 plans the reinforced concrete intermediate ceiling with 30 cm and has a lot of freedom in the placement of the walls. Architect-2 calls this "letting the forces wander" and means that, for cost reasons, the load-bearing walls should be better planned and then managed with 22 cm of reinforced concrete. The construction supervisor calculates 260 sqm * 8 cm = 20 m3 (additional) reinforced concrete * 150 € (85 per m3 concrete plus steel) = 3000 € and no reason to adjust the floor plan. Of course, the final word lies with the structural engineer, and small wall shifts don’t hurt anyone. But I also tend not to compromise on the floor plan design over 3000 €. I look forward to your comments on this.
