Hello,
Renovating a house with a timber frame, from the late 1800s.
The intermediate floor = the floor between the ground floor and the upper floor consists of logs with CC 110-120.
The floor compartments are filled with sawdust and charcoal breeze. On top of that lies a wooden floor that is about 20 mm. Plan A is to keep it as it is and then add two layers of flooring chipboard (a floor chipboard panel + a grooved panel for waterborne heating). On top of that will be tiles or laminate flooring.
Do I need to regel more densely, for example, CC60, or will it be stable enough with the flooring chipboards? Or could it be that we won't meet any BBR requirements if we do so?

BBR is not something you need to worry about. To assess your question, it is necessary to know the span and cross-sectional dimensions of the beams. Two layers of chipboard flooring, one of which is grooved, is probably not optimal for that c/c distance (entirely normal considering the age). Simple summary of the problem: The beams must be stiff enough to handle the load placed on each beam. What lies across the beams must handle the current load considering the c/c distance.
