[Tanjusha]

прошу помочь с переводом фразы

[Tanjusha]

Добавление: проектировать с заведомо завышенными требованиями к прочности

[Alex Nord]

to design with obviously steep demands

[kath]

design with intentionally higher durability expectations

although, as always, context context and more context!

[Анатолий Д]

deliberately/intentionally overestimated strength specifications/requirements

kath
прочность=strength
durability=долговечность

[Turk]

как вариант:
...intentionally conservative robustness expectations. imho

[kath]

Anatoly D - i would have to disagree. not with your definitions but their application. if it said 'prochnost materiala' - i would use 'durability of fabric' not 'strength'. all depends on context, as i mentioned earlier

[felog]

Почему нельзя использовать overdesign

[Анатолий Д]

kath

I would be pleased to agree with you if we had more context available.
Both are possible because they may mean a specific structure designed to resist a blast, for example.

[Troll]

design with excessively stringent strength/robustness (whatever suits the context here) requirements

[D-50]

consider Safety Factor

[Mo]

согласна с D-50 с дополнением: to design with an increased safety margin или to build a higher safety margin into (the) design

[pupil]

а я склонен согласиться с felog. Overdesign - коротко, емко, встречалось в работе
