Let us compare your question to the care and maintenance of an automobile.
1. Car manufacturers provide a schedule of maintenance that needs to be performed on a recurring basis. This is the maintenance program.
2. If we know that the timing belt is going to last for 80-100,000 miles, then we could replace it as soon as we reach 80 thousand miles to prevent having it break while we are on vacation or at some other inconvenient time. If the brake pads wear out after 40,000 miles then we could replace them before they wear so much that they damage the rotors. This is preventive maintenance.
3. It there is a defect that is discovered after the car and similar models have been in service for a period of time, then it may be recalled to have the problem fixed. This would be corrective maintenance.
4. If the tire goes flat or if a radiator hose bursts, or if some other part breaks and disables the car, then one would have to make emergency repairs.
5. If the car is getting older and the engine and transmission no longer perform satisfactorally, then we might need to rebuild all or part of it. This would be restoration or rehabilitation. If our car is an antique, it may have been built without seat belts, an air conditioner, or some other component that needs to be added to make it safe or more useful. Then we would retrofit it with the proper parts.
Now if we could just drive our skyscrapers into the local skyscraper repair shop and get them back the next day, we would be all set.
