Assignment: Terminal 2E at Charles de Gaulle

Outline

Introduction:

A. the terminal 2E at Charles de Gaulle in Parise, France has an issue with its design which caused collapsed several months after its open.

B. On 23th, May 2004. One of the biggest airports in the world that costs around 900$ has a problem in its design system. What happened I that thelarge piece of roof fell down, and it killed four people and three were injured

C. This failure played a crucial in roll improving engineers' skills and changing their common mistakes

Technical and Commercial Aspects:

A. Role of technology in the failure

1- Materials, techniques or service condition

a. The mental support structure was found into concrete
b. Putting different parts of structure
c. Engineers did not test the concrete very well

2- what were the lessons learned

a- The concrete that used in the terminal 2E as structure were weak

b- The terminal 2F, which is like terminal 2E was made with same design, but it had built with 5400 tons of steelwork.

c- Terminal 2E was built with concrete instate steelwork to keep the cost down. using the concrete instate of steelwork was the major factor of fell the roof down.

d- Result, the terminal 2E and 2F have same design, but it had built with different materials. 2E that built with concrete fall, 2F that built with steelwork still standing.

3- Advice to improve business practice and engineering design.

a- This project can be used to improve engineers and business practice in their experience. For example, using a different material that maybe work isunacceptable even though it passes the test, especially in the big project like airport. In a project like airport the economy chose is not that important as the quality of the material.

B. Causes of the failure

a. Lack of redundant support
b. Weak outer steel struts
c. Weak concrete support
d. Low resistance to temperature
e. Poorly placed reinforcing

1- Ethical causes

a. Economy choose
b. Engineers did not spend enough time on research

2-Societal Impact for the failure

Charles de Gaulle airport that second busiest airport in Europe, so people got surprised when they heard that a terminal roof fall.

Methodology and insights

a. I am going to condition my overall research by explain some important points that describe the failure case such as roll of techniques, lessons learned, causes of failure, societalimpact, and advice to improve engineer design.

b. Based on my research I understand that the mistakes are happened in the engendering world, and I should think as an engineer to do not do any mistake that will cost me a lot.

c. The new question that I have about engineering failure is that how is that passible to have a failure project with these new amazing technologies that we have on our current time?

Conclusion

a. This failure played a crucial in roll improving engineers' skills and changing their common mistakes.

b. Summarize the research main points

1- Roll of the technology in the failure
2- Materials and techniques
3- Causes of the failure
4- Methodology and insights

c. Finally, a failure in a project could happen in any engineer's career, but the good engineer is the one who could predict it before happening, or he gets out with the least of costs. however, the terminal 2E had collapsed because the engineers used different material that cheap and less quality than they had to used.
