With that preamble, let us now consider each of the site safety factors listed above and the extents to which they apply to subcontractors, GCs, A/Es, and owners. The reader will note that this analysis is a practical one. That is, the analysis is based on actual processes (i.e., the way it actually happens in the field), OSHA requirements, or economic considerations that entities should consider to maximize profits. The analysis does not rely on moral or ethical grounds.
