That is absolutely false. I design bridges on a daily basis and there is absolutely never a 5:1 factor of safety. On some components you may get as high as 2:1, but generally it's much below that. Computer models are also not allowed as a sole means of ana.lysis, there must be hand calculations to support any computer models.
