What is Infrastructure? “A civilization’s rise and fall is linked to its

ability to feed and shelter its people and to defend itself. These capabilities depend on infrastructure - the underlying, often hidden foundation of a society’s wealth and quality of life. A society that neglects its infrastructure loses the ability to transport people and food, provide clean air and water, control diseases, and conduct commerce.” NSF, ‘Civil Infrastructure Systems Research’,

1994.

What is Infrastructure? (2) “The nation’s infrastructure is its system of

public facilities, both publicly and privately funded, which provide for the delivery of essential services and a sustained standard of living. This interdependent, yet self-contained, set of structures provides for mobility, shelter, services, and utilities… America’s infrastructure is the base upon which society rests. Its condition affects our lifestyles and security and each is threatened by its unanswered decay.” Associated General Contractors of America, 1982.

Milestones in (U.S.) History Has generally paralleled economic development Roads Railroads Telegraph/ Telephone Sewer/Water Supply Systems (1800-1850) First federal highway funds (1918) Franklin Roosevelt - public works funding (1930) Interstate Highway System (1950)

What is Infra. Mgmt.?Administrative process of creating,

planning, and maintaining our infrastructures

An integrated, inter-disciplinary process that ensures infrastructure performance over its life cycle

Life cycle is entire time from design through decommissioning

resourcesMaximize performance of assetsServe all management levels

Key Issues Decay and deterioration (condition, failure) Lack of maintenance/renovation (build, build,

build!) Scarcity of financing (federal gov’t funds

projects of national/interstate importance - states left to build the rest; money tends to be for construction and not maintenance; lots of infrastructure needs - which ones are #1 priority?)

Inadequate reporting and accounting

Where Does Engineering Help?Systems engineering perspective!

Framing of problem Using quantitative tools to solve it

Tools: uncertainty/risk analysis Optimization via LP, Probabilistic, etc.
