Hi Mohan,
Plant Maintenance is mostly common for all Production Industries. There are certain industries they prefer to maintain history via functional location, not via equipments. So you need to confirm whether what is feasible and what is their requirement.
As far as i have seen, below are list of Master data you will require.
Functional Location
Equipment
Class and Characteristics
Measurement Point / Counters / Documents
Work Centre
Task List
Maintenance Plan
Maintenance Stratergy
Catalog
