This is one of the facts of life; no matter how well the original job is performed, there is no way to control the future.
For example, everyone seems to consider the electric room to be a perfect place for storage, a workshop, or a maintenance office. Panels, when place in hallways, ALWAYS cause major objections when you close off the hallway so that you can work safely.
Then there are environmental issues. Again, there is often no way to predict the factors that will be supplied later, by the customers. This is especially the case where physical damage becomes an issue.
Probably, though, the biggest culprit is the architect. For whatever reasons - inaccurate customer input, 'design elegance,' economy, or even simple ignorance - buildings never seem to have realistic provisions for either storage or support operations.
As a result, folks do what they have to do.
