Below the 3D V lifecycle of a building construction project.

As you can see, there are always 3 dimensions for the Work (ABS, PBS, ZBS) and we can add the fourth dimension OBS to describe the whole schedule.
To be noted that OMNICLASS, that is a standard for Building construction, has 15 tables but not 15 dimensions ! Because each table belongs to either PBS, ABS, ZBS or OBS. Each table answers only one elementary question: What?, How? Where? or Who?. So, it must be clear that OMNICLASS has only 4 dimensions.
