ᐅ Clearance between wheelchair-accessible balcony threshold and floor level

Dear forum members,
for our building project, we planned for accessibility and therefore specifically included aluminum thresholds for the balcony doors. Now the floor installer left a large gap between the threshold and the floor (see photo) and claims this is within the tolerance range. Do you have any ideas which DIN standard we can refer to in order to contest this? Unfortunately, our architect is not supporting us.

If you want an almost threshold-free transition, you clearly move beyond the scope of the standard tolerances defined by DIN for all components to be joined and enter the realm of absolutely necessary, first, detailed drawings by the architect and second, a clear determination of which trade must use which part as the master reference measurement.

This could be the door fitter or the floor installer. But if each of them works independently as in the standard case, everything will not align perfectly unless chance or luck intervene.

If the floor covering did not allow the floor installer to "ramp up," then the door fitter would have to be the one working afterwards.

A separately purchased special component alone will not ensure proper fitting any more than a swallow makes a summer. Architects know this; general contractor planners often do not.

The floor was installed after the door, and as luck would have it, the floor of the first door (10 units) was almost flush.

Of course, a zero deviation is still within tolerance.

Are you the only one of the ten units that has selected these special thresholds?

Ten units also suggests a developer project – what is your position in relation to the floor installer?

Is there any update on this? I’m in a similar situation. However, my gap is almost 2 cm (0.8 inches). I’ll probably just have to accept it.
