• No class Wednesday, lab canceled.
![Page 3: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/3.jpg)
What is Engineering?
• Engineering vs. Science
• Design
• Analysis vs. Synthesis
![Page 4: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/4.jpg)
• Most engineering work gets done is projects
• What’s a project– in your own words
![Page 5: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/5.jpg)
What is a project?
• One-of-kind undertaking
• Definite objective
• Start and end points
![Page 6: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/6.jpg)
Engineers work
• Owners of Projects– planning, administration, expert advice
• Design of Projects– A/E
• Construction– planning, bidding, administration, design
• Regulation, Operations, Maintenance
![Page 7: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/7.jpg)
Project Life CycleRecognize Nee Recognize Need Design? Budget
Conceptual Phase 5-15% +/- 100%
Design 35, 95, 100%
+/- 10%
Production or construction Changes
Operation, Turn-on O&M
Divestment, Tear down
![Page 8: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/8.jpg)
Three aspects of P.M
• Schedule– time
• Cost– budget
• Production– performance, specification
![Page 9: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/9.jpg)
Bar Chart Schedules
• Most common
• Simple
• (Excel)
![Page 10: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/10.jpg)
WBS
• Cost codes
• (Excel)
![Page 11: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/11.jpg)
Types of Estimates
• Rough - gut level, inaccurate -30% to +60%. ROM
• Semi detailed - based on historical records, reasonably sophisticated and accurate -15% to +20%.
• Detailed - based on detailed specifications and cost models, very accuracy -3% to +5%.

Difficulties in Estimation
• One of a Kind– Estimation by analogy
• Time and effort available
• Estimator experience
![Page 15: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/15.jpg)
Take Home Thoughts
• Most engineers work on projects• Projects have a life cycle• Accuracy of estimates increases with design
completion• Projects must be managed with attention to cost,
schedule, and performance• Projects are estimated and tracked with a work
breakdown structure• Changes to design cost more as the project
progresses
![Page 16: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/16.jpg)
Engineering as a Profession
![Page 17: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/17.jpg)
What is a “profession?”
• Specialized education leading to knowledge and skills not commonly possessed by the public
• The work requires exercise of discretion and judgment and is not subject to standardization.
• The profession has legal status and requires well-formulated standards for admission such as registration or licensing
• Standards of conduct are set forth in codes of ethics
![Page 18: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/18.jpg)
• Group consciousness promotes knowledge and professional ideals through societies and associations.
• The professional community exercises oversight and control of member conduct
• Activates satisfy indispensable and beneficial needs, with service to the public as the foremost motive.
![Page 19: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/19.jpg)
Professional licensing
• AKA “Registration”• Dates to early 1900
– Chaos with development– Texas one of last
• Most countries have similar laws• Laws and Regulations• Law establishes Board of Registration
– Promulgates regulations
![Page 20: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/20.jpg)
Alaska
• Has unified board of Architects, Engineers, and Land Surveyors
• Belongs to NCEES– National Council of Examiners for Engineering
and Surveying– Develops Exams (FE and PE) and– Suggests policy
![Page 21: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/21.jpg)
Licensing
• Education– 4 years ABET
• Experience– 4 years
• Examination– Pass both FE and PE
![Page 22: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/22.jpg)
Why does society issue licenses?
![Page 23: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/23.jpg)
![Page 24: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/24.jpg)
Protect the Public
![Page 25: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/25.jpg)
Why get your license?
• Certain jobs require it
• You must have it to consult
• In many situations it improves your chances for promotion
• Professional pride
• “Industrial exemption”– Dilbert doesn’t have license
![Page 26: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/26.jpg)

Professional Ethics
• Engineering ethics
• Rules and standards that govern our engineering choices and decisions
• How should we conduct ourselves in our professional capacity?
• Cost vs. safety.
![Page 33: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/33.jpg)
• Engineers handle complex matters– future effects
• Personal vs. Professional Ethics• Personal
– How we treat other persons
• Professional– Corporations– Governments
![Page 34: ES 101 Projects and Ethics Dr. Robert A. Perkins, PE raperkins@alaska.edu.](https://reader035.fdocuments.us/reader035/viewer/2022062712/56649c9d5503460f9495ce3c/html5/thumbnails/34.jpg)
Why teach ethics
• Good people know the right thing to do and do it.
• Bad people are not going to do the right thing.
• Heat recovery system.

Code of Ethics
• NSPE
• All major engineering societies similar
• Alaska (all most states) regulations
• Intent of Code is encourage/regulate professional conduct for the good of society.
