<strong>Ethical</strong> <strong>issues</strong> <strong>in</strong> eng<strong>in</strong>eer<strong>in</strong>g <strong>design</strong><br />
In short, there is a regulative framework consist<strong>in</strong>g of European <strong>and</strong> Dutch<br />
legislation, codes, certification, ideas of <strong>in</strong>terpretations, teach<strong>in</strong>g materials <strong>and</strong><br />
courses. Does this regulative framework meet Grunwald’s requirements <strong>for</strong><br />
normative frameworks? The requirements were outl<strong>in</strong>ed <strong>in</strong> section 2.3.2. A<br />
normative framework should be pragmatically complete, locally consisted,<br />
unambiguous, accepted <strong>and</strong> observed [Grunwald, 2000] <strong>and</strong> [Grunwald, 2001].<br />
Pragmatically complete: The framework is reasonably complete. Accord<strong>in</strong>g to<br />
the eng<strong>in</strong>eers, most of the decisions that have to be made are encompassed by<br />
the framework. There is one subject that is not dealt with explicitly <strong>in</strong> the<br />
framework: misuse.<br />
Locally consistent: Most elements of the framework are l<strong>in</strong>ked <strong>and</strong> there is little<br />
contradiction because the build<strong>in</strong>g decree is the decisive document. The<br />
construction should, <strong>in</strong> the end, comply to the Dutch build<strong>in</strong>g decree. Possible<br />
contradictions arise if parts of the construction can be <strong>design</strong>ed us<strong>in</strong>g one of two<br />
types of codes <strong>for</strong> example a geotechnical or a construction code but this is the<br />
exception. Different codes pose different requirements, so the same part will<br />
look different when <strong>design</strong>ed accord<strong>in</strong>g to different codes. This problem arises<br />
only <strong>for</strong> certa<strong>in</strong> parts of certa<strong>in</strong> constructions <strong>in</strong> which the type of code that<br />
should be used is not fixed <strong>and</strong> can be debated. So, strictly speak<strong>in</strong>g the<br />
framework is not locally consistent, because it allows, <strong>in</strong> some cases, the use of<br />
different types of codes.<br />
Unambiguous: At this moment the framework is unambiguous, but the new<br />
European code will cause temporarily problems. In the near future the European<br />
code <strong>for</strong> loads on bridges will become available <strong>in</strong> a green version. At that<br />
moment both the old NEN codes <strong>and</strong> the new European code can be used. Until<br />
the European code is available <strong>in</strong> a def<strong>in</strong>ite version this situation will cont<strong>in</strong>ue.<br />
Eng<strong>in</strong>eers can, dur<strong>in</strong>g this time period, choose between the codes. Some<br />
eng<strong>in</strong>eers may choose immediately to use the new European code because the<br />
fatigue load predictions are better, other eng<strong>in</strong>eers may choose to cont<strong>in</strong>ue us<strong>in</strong>g<br />
the old NEN codes because they have experience with these old codes.<br />
Accepted: The framework is accepted by the IBA eng<strong>in</strong>eers <strong>and</strong> accord<strong>in</strong>g to<br />
them the framework is widely accepted <strong>in</strong> the eng<strong>in</strong>eer<strong>in</strong>g profession. There is<br />
little evidence that the public or policy makers or eng<strong>in</strong>eers do not accept the<br />
framework. With regard to the <strong>design</strong> process <strong>for</strong> a bridge there are no signs that<br />
the framework is contested. The public seems to accept the bridges that are built.<br />
There have not been any recent disasters with bridges <strong>in</strong> the Netherl<strong>and</strong>s, so<br />
there is little reason <strong>for</strong> the public to doubt the framework. The Van<br />
Brienenoordbrug case is an example of problems caused by us<strong>in</strong>g the NEN<br />
