ABSTRACT
Many infrastructure owners now find themselves in a situation where it is no longer possible to spend only the predicted minimal long term resources to maintain their bridges. This has occurred due to reductions in funding to levels below the required expenditures for optimal long term management of bridges that have lasted multiple years and that have not been followed by periods of time with the additional funding required to catch-up. This normally happens due to the inability of infrastructure managers to provide solid estimates of the financial needs required and proof that their suggestions are optimal.
