Activity classification for heavy infrustruction projects

I'm looking for a standard as a base in order to establish an activity classification system for heavy infrustructure works.

The target will be to conect accounts, wbs, reporting and cost control.

I have revies the Masterformat system but it is based mostly for buildings.

From a research i found that there are some other systems like :

Omniclass, Uniclass, NAIS, CAWS, NBS, ASTME256 and others.

Any proposa ?, mainly  i am interest for industrial works, rail, marine etc.

I am not sure yet if a standard is better than a custom one.

Thank you
