As shown by the percentages in the row labeled GCs, the highest percentage of respondents in all three groups ascribed primary responsibility for site safety to GCs. Few respondents ascribed primary responsibility to A/Es or owners. Interestingly, both A/Es and subcontractors had substantially higher percentages of respondents who attributed primary safety responsibility to their own group. That is, the percentage of A/Es who believe that A/Es should have primary responsibility for site safety is higher than the percentages of GCs and subcontractors who believe that A/Es should have primary responsibility.
