Hi Kent,
Good questions!
Our department operates and maintain water treatment plants, water pumping stations and water tanks for Montréal city. So we have the same reflection.
Initially, we have split our infrastructures in 3 categories: process, buildings and tanks.
For process, we have a specific hierarchy with all physical equipment dedicated to the process.
For tanks, we have water tanks only (underground and concrete tanks).
For buildings, we use UNIFORMAT and the hierarchy stop at the level 3 (X 11 11).
So for each building we have a uniformat hierarchy. The number / name of the element is the uniformat number / name for the building.
Example: Building Y - B Shell – B10 Superstructure – B1010 Floor construction.
We consider each level 3 like a "point" asset. We have the estimate (quantity and cost) , the description of each intervention and estimate year of completion for each level 3.
This data comes from an audit and, after that, we can organize the work (maintain, project, etc), evaluate the investments needs and follow the status of the building.
I think the key is, in the first time, evaluated the data and details you need.
Actually we don't have integrated the building hierarchy in our CMMS.
I hope you find this information useful.
Looking forward reading more experience.

Subject: Building Hierarchy - implementing an asset hierarchy for building structures/elements in your CMMS system
Hi everyone,
I would like to survey the group here to see if anyone has been involved with implementing an asset hierarchy for building structures/elements in your CMMS (Computerized Maintenance Management System) or, alternatively, how many use a separate facility management solution?
Our regional district (Metro Vancouver) operates and maintains a wide range of Asset Classes (e.g. Waste Water Treatment Plants, Water Treatment Plants, Sewage Pump Stations, Water Pump Stations, Sewage Collection system, Water distribution system and Works Yards).
Within our CMMS, our current equipment hierarchy contains "systems", "positions", and "assets", in that order. "Assets" can be thought of as the physical equipment, "Positions" can be thought of as the physical location of the equipment (i.e., its parking space), and "Systems" are used to organize positions into different groupings. This works well for single or 'point' assets; however, for building elements, there will be times when we do not want to break everything out into separate positions. For example, we would not want to create a separate position for every single exterior wall on a treatment plant.
Unfortunately, we cannot track all exterior walls at the system level only because we are unable to assign quantities and costs to the system level. We could define a single position for a group of exterior walls but we were wondering what others were doing?
In particular, we would like to hear how:
- You have incorporated a building hierarchy into your CMMS.
- What hierarchy you are using for building elements (e.g., ASTM UNIFORMAT II).
- How equipment naming / numbering is assigned to building elements.
Look forward to hearing your experience and thoughts!
