Service LifeService Life
• Physical service life is the length of Physical service life is the length of time which a piece of infrastructure is able to be kept in useful service– Depends on all life cycle phases– Can be extended from original design due to
rehabilitation or preventive maintenance

What is GASB-34What is GASB 34
• GASB stands for Governmental Accounting Standards Board
• The number refers to Statement 34, issued in June 1999,
• GASB-34 is a new reporting standard for utilities that treat infrastructure as investments instead of expensestreat infrastructure as investments instead of expenses
• GASB-34 is important because it recognizes that infrastructure’s service life is usually extended infrastructure’s service life is usually extended indefinitely and encourages the adoption of an Infrastructure Asset Management Plan

The Four Pillars of Sustainable Urban TransportationUrban Transportation
• The unsustainable nature of current The unsustainable nature of current urban transportation and land use is well recognized. What is less clear is the prescription for how to move towards a more sustainable future,
i ll i th i t t especially given the many interest groups involved, the complexity of urban systems and the fragmented urban systems and the fragmented nature of decision-making in most urban regions.

• It is argued that the process of It is argued that the process of achieving more sustainable transportation requires suitable establishment of four pillars: – effective governance of land use and
t t i i f t t i t t d– strategic infrastructure investments; and– attention to neighborhood design.

• Not just a matter of technology, requires an integrated approach from policy, technology, education, operation, and, p ,

What is ResilienceWhat is ResilienceAccording to Walker 2006:
• Management paradigm and body of management practices
• Applied to the entire portfolio of infrastructure assets at all levels of the organizationg
• Seeking to minimize total costs of acquiring, operating, maintaining, and renewing assets…Withi i t f li it d • Within an environment of limited resources
• While continuously delivering the service levelscustomers desire and regulators require
• At an acceptable level of risk to the organization

View 7: Seven Principles of Asset Managemente Se e c p es o sset a age e t
1. The “Value Added/Level of Service” Principle—assets exist to deliver services and goods that are valued by the customer-deliver services and goods that are valued by the customerstakeholder; for each consumer-stakeholder there is a minimum level of service below which a given service is not perceived as adding value.
2. The “Life Cycle” Principle—all assets pass through a discernable f flife cycle, the understanding of which enhances appropriate
management.3. The “Failure” Principle—usage and the operating environment work
to break-down all assets; failure occurs when an asset can not do what is required by the user in its operating environmentwhat is required by the user in its operating environment.
4. The “Failure Modes” Principle—not all assets fail in the same way. 5. The “Probability” Principle—not all assets of the same age fail at
the same time. 6. The “Consequence” Principle—not all failures have the same
consequences.7. The “Total Cost of Ownership” Principle—there exists a minimum
optimal investment over the life cycle of an asset that best

p ybalances performance and cost given a target level of service and a designated level of risk.
