Michael,
The facility, utility and infrastructure assets typically fall in to the following categories:
1. Civil Assets like Buildings, Roads
2. Assets in Steam+Electricity generation Units and their Auxiliaries, HVAC Units, Thermic Fluid Circulation, Emergency Power
3. Safety/Fire Fighting Systems like Fire/Gas/Smoke Detection, Fire Fighting
4. Mobile Assets like Portable Diesel Generators, Hydraulic Power Packs, Cranes
I share below my experience with SAP-EAM:
The Assets are determined to be created as a) Functional Locations (FL) only, b) Positional FL with Equipment (internally generated no. in CMMS) and c) Equipment only (with out Pos FL). Assets are created as Equipment where the Asset moves between different FLs (Rotables) or where the need is to capture the Maintenance history, cost on Equipment and Pos FL both.
I've seen the following approach:
1. For Utility Assets high level Functional Locations (based on Process Unit/Systems) are created based on the Structuring Philosophy (typically Site/Business/Sector/Plant/Area/Sub-Area).
Subsequently lower level FLs for each Asset like Static Equipment (e.g. Steam Generator, Fixed Pressure Equipment). Positional FLs are created where Equipment need to be installed (e.g. Pump/Motor).
For Assets like Pump/Motor, Equipment is created separately and installed in their Pos FLs. In CMMS like SAP, Equipment has a Internally generated no. + a specific Sr. No. of the Asset
For Piping within the Fixed Equipment Package or running between Assets within the Plant, FLs can be created as per Area (Pipe Racks) or as per individual Piping (based on the business and maintenance needs)
2. For Facility Assets like Civil Structures/Buildings, only high Level FLs (Spatial FL) are created (e.g. Building/Block/Wing/Floor/Hall or Cabin).
Other Assets that are part of or installed in the Buildings like Fire/Gas Alarm Systems and Firefighting Systems are created as either Pos FL+Equipment, FL only or Equipment only based on the specific need (need for granularity in Asset Structure, need for capturing history on a piece of asset vis a vis the FL etc.). For example, fixed Fire detection system/Detectors are created as FL only and portable Fire Fighting Equipment are created only as Equipment and installed in the higher level FL.
3. For Infrastructure Assets like Roads, Cabling Networks the Functionality of Linear Asset Management can be explored, depending on the business needs. Similarly piping carrying Fire Water, Steam, Thermic Fluid etc. can be created as Linear Assets.
4. For Mobile Assets that are shared across the Site (between Plants/Units etc.), Equipment can be created for each such Asset and installed at the higher level FL created for the Bay/Area where they are normally available (owner's pool). They can be issued to each Job against the Work Order and returned to the Owner/s.
Hope this helps. Thanks

I was wondering if anyone had good examples or reference about how to organize facility, utility, and infrastructure assets within a CMMS system???
