6 What went wrong? Where was the failure in the design and build process?

7 Investigation Results The collapse was a result of the box beam failure.

8 Was this unethical?

9 The Trial The detailer, architect, fabricator, and technician all testified that they had contacted the project engineer regarding the structural integrity of the connection detail. The project engineer assured them that the connection was sound, claiming to have checked the detail. He never performed any design calculations.

10 Neglecting to check the safety and load capacity of a crucial hanger even once shows his complete disregard for the public welfare. (Rubin and Banick, 1987)

11 The Code of Hammurabi Babylonian Law, 1750 BC If a builder build(s) a house for someone, and does not construct it properly, and the house which he built fall(s) in and kill(s) its owner, then that builder shall be put to death If it kill(s) the son of the owner, the son of that builder shall be put to death.

20 Ethics Case Studies - can you get them all right?

21 How this will work 5 case studies I ll present each case and leave details up on the screen 90 seconds to discuss with those around you who is at fault and why? After discussion, clicker question will open Reveal answers Best answer Ok answer

22 Case Study 1: TV Antenna Tower Collapse

23 TV Antenna Tower Collapse Antenna Engineering is hired by TV company to design a new 1000 foot microwave antenna tower. Riggers Inc. is hired to raise the antenna in place. Antenna Engineering sends a final copy of the hoisting design to Riggers Inc. and they approve of it. When getting ready to lift the final piece of the antenna, the riggers realize that the microwaves interfere with the original hoisting lugs. They ask Antenna Eng. for help, but the engineers refuse. The experienced riggers redesign the hoisting lugs and lift the final piece into place. At the top of the tower, the hoisting lugs fail, the tower collapses, and 7 people die. Who is at fault? TV Station? Antenna Engineering? Riggers Inc?

24 Case Study 2: Anhydrous Ammonia Hose Failure

25 Case Study 2: Anhydrous Ammonia Hose Failure Anhydrous ammonia is an extremely caustic liquid fertilizer used in farming. XYZ Corporation makes stainless steel hoses for farmers to deliver anhydrous ammonia to their field. The equipment, including the hoses, is rented from a local farmer co-op. Engineering Professor published paper stating that a new material, AAH1, can be used but that it fatigues by 46% over time. XYZ Corporation decides to save money (for themselves, the co-op, and the farmer) and make hoses out of AAH1 instead of stainless steel. XYZ and several independent labs test AAH1 hoses and find that they meet all industry standards set by The Fertilizer Institute. Several AAH1 hoses rupture and cause permanent injuries to farmers. Who is at fault? XYZ Corp? Farmer Co-op? Fertilizer Institute?

26 Case Study 3: ASME vs. Hydrolevel Corp.

27 Case Study 3: ASME vs. Hydrolevel Corp. McDonnell and Miller own M&M Corp., a company that produces gauges for pressure vessels. McDonnell and Miller also both serve on the Pressure Vessel Committee of the American Society of Mechanical Engineers (ASME). M&M Corp. requests an interpretation of the ASME Boiler and Pressure Vessel Code (BPV). M&M salespersons use this interpretation to demonstrate to customers that their competitor, Hydrolevel, is not meeting the BPV Code. Hydrolevel quickly loses market share and goes bankrupt. Who is at fault? No one? ASME? McDonnell and Miller?

28 Case Study 4: Shanghai Apartment Building

29 Case Study 4: Shanghai Apartment Building A 13-story apartment building was constructed as part of a complex. The building has no basement. The pilings are hollow concrete cylinders that go to the depth required by the construction standard (developed by the local government). Diggers, a contractor, was digging a 4.6 meter underground garage on the south side at the direction of the project design engineers The excavated dirt was piled on the opposite side of the building. The uneven lateral pressure sheared the building pilings and the building fell, intact. Who is at fault? Maker of the standards? Design Eng.? Contractor?

30 Case Study 5: Gilbane Gold what would you do?

31 Case Study 5: Gilbane Gold Gilbane is known for having sewage that is completely free of toxins and heavy metals. The City of Gilbane sells it s sludge as a high quality fertilizer, saving each citizen of Gilbane $300 a year in taxes. The City of Gilbane has a parts per million (PPM) discharge restriction 10-times stricter than the Federal standard. X Corp., a local manufacturing company, produces computer components and discharges heavy metals in the waste stream. X Corp. self-monitors their monthly emissions and reports them to Gilbane. You are a new environmental engineer at X Corp., hired to monitor the discharge amounts. You learn that X Corp. is slightly above the allowed PPM discharge rate. You learn that X Corp. is planning on ramping up production two-fold and be increasing its overall discharge. What would you do? Tell the city? Tell the plant manager? Alert the news media?

32 As an engineer, you must think about the implications of your choices. Ask for advice from more experienced engineers whenever approaching an unfamiliar situation. Plans fail for lack of counsel, but with many advisers they succeed.

33 Alpha Testing (Next week during lab) - 50 points Come straight to shop (IDE room G3E) Test set-ups on welding table 2 set-ups, 1 team testing, 1 on deck Each team has 3 minutes for testing We will fill out a test sheet for you with feedback See details on grading criteria in last week s lecture Minimum complexity requirements will be announced after alpha testing

34 Beta Testing (Week 12) - 50 points Same test set-up/timing as alpha testing Scoring Performance 1 Timing (15 points) 30 +/-1 second = 15 points 30 +/-2 seconds = 10 points 30 +/-3 seconds = 5 points Performance 2 Sufficient activation force (10 points) Complexity (15 points) For full points: meets minimum complexity OR there is a clear plan for changes to be made before final testing to achieve this minimum. Improvement/Refinement from Alpha Prototype (10 points)

35 No Lecture Next Week! (11/2 or 11/3) Attendance during lab for alpha testing will count as clicker points for week 11
