higher maintenance expense

[Antonio Gomez Ochoa]

Good morning, I have the following doubt, and that is: Taking into account the durability criteria of the systems, in general terms. When do the moments of greatest spending occur in building maintenance and system renewal?
It would be very helpful to receive an estimate on this question, thank you very much.

Good morning! Sure, I'd be happy to help. Typically, in terms of building maintenance and system renewal, the moments of greatest spending often occur around the 20-year, 30-year, and 40-year marks.

it would depend on ...
1) the durability of the original installation; was it designed for a 20 year life or a 40 year life ?
2) how well does the experienced usage compare with the assumed usage (as used in the design) ?
3) how well (quality) was the original installed built ? (was it to code, or not) ?
4) how well has the installation been maintained ? (to the expected maintenance, or left to rot)

the moments of greatest spending typically occur when preventive maintenance is neglected to the point that things start failing unexpectedly. then you have not only the cost of replacing the broken bits you have the expense of the equipment being down for a long time with delays to production, etc.

and the people who have to bear that cost (the current management team) are looking around for people to blame (the previous management team) ... t'was ever thus.

I would imagine that the cost curve would looks something like a reliability bathtub curve; somewhat high expenses at the beginning when infant mortality and teething pains occur during installation, initial startup, etc., followed by a period of relatively constant costs, followed by increasing costs as older equipment and installations require major overhauls or outright replacements.
