Not necessarily. Hypothetical of two alternatives:
1. Do a small renovation to a bridge and it will stay usable for five more years, or
2. Do something more comprehensive (teardown + rebuild), after which you don't have to do anything for 20 years
If there's a temporary high in building costs, it makes sense to do 1. If there's a temporary low, it makes sense to do 2.
