People Deserve To Know How Safe Is Safe Enough

摘要

A condominium developer in California brags about a 30-in.-thick concrete core with double-helix-style stairwells that "enhance" safety. At about the same time, structural engineers testify at an International Code Council hearing that a proposed commercial building code to harden stairwells should be thrown out because, among other reasons, it is not based on any demonstrated "significant" risk to a building (see p. 13). Simply put, where's the projectile? The proposal is vetoed.
