The term “Public Works” is applied to facilitates that usually require substantial capital investment; provide services or solve problems perceived to the public's responsibility; and are planned, designed, constructed, and proposed by or under the auspices of government agencies. Private companies may also construct and /or operate public works, to serve their own manufacturing or other need, or for profit.
Definition of the "Public Works" and " Infrastructure"
![Page 3: Lecture(1) Civil Engineering Dept. Master Program Civil Engineering Dept. Master Program 2013-2014.](https://reader036.fdocuments.us/reader036/viewer/2022070407/56649e215503460f94b0cbd3/html5/thumbnails/3.jpg)
“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”.
What is Infrastructure ?

3
Routine maintenance(preventive) and operation of infrastructure system (e.g., the municipal systems for transportation, water supply, sewage and storm water and solid wastes.
4
Improve the system efficiency by modify the operation and management (e.g. Improve pumps efficiency by cleaning or/and lubrication ).

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

What is Infra. Mgmt.? 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

Systems engineering perspective! Framing of problem Using quantitative tools to solve it
Tools: uncertainty/risk analysis Optimization via LP, Probabilistic, etc.

Programming and budgeting
process of public works agencies
ProgrammingIt is a process of prioritizing proposed projects and developing a single-year or multiyear program of projects, usually within a constrained monetary amount.
• An annual preventive maintenance program.
• A five-year capital program(what capital improvements will be designed and constructed over the time period ?)
Examples
![Page 25: Lecture(1) Civil Engineering Dept. Master Program Civil Engineering Dept. Master Program 2013-2014.](https://reader036.fdocuments.us/reader036/viewer/2022070407/56649e215503460f94b0cbd3/html5/thumbnails/25.jpg)
Programming and budgeting
process of public works agencies
BudgetingIt is procedures that actually produces the funding and authority to incur costs and allocate funds. The budget is usually an annual legislative authorization for expenditures and may follow multiyear authorization guidelines established be by the same legislative bodies.

Relationship between infrastructure and development
A healthy infrastructure is a necessary ingredient of a robust economy. Infrastructure systems are a part of the nation's economy (through expenditures), and infrastructure systems are also necessary to accommodate economic expansion and productivity.

Our Purpose - Now Justified
Understand issues in managing existing infrastructure rather than building new
Critically review status of infrastructureDevelop awareness of tools and resources
for infrastructure management
For next time: read Dunker 1995
