Sure, your building design company would last a long time if every flight of 
stairs had a tolerance of +/- 25 mm... :-)

Yeh, just like a 2D drawing of a mechanical part, the plans are to enable 
the builders to actually make the building.  They need dimensions of every 
part, material types, finishes etc.  They don't want to have to keep phoning 
up the designer and asking "errm, how thick do you want this wall?" and 
stuff like that.
