The ability of A/Es to evaluate unsafe site conditions also depends on the type of condition, but the reasoning is different from that for GCs and subcontractors. A/Es’ ability to identify visible unsafe conditions is low because they are on-site so infrequently. A/Es’ ability to identify and prevent some hidden unsafe conditions, on the other hand, may be higher than the abilities of subcontractors or GCs. Specifically, A/Es are in the best position to implement the specific safe design recommendations reported by Gambatese et al. (1997), thereby preventing the need for some less safe conditions to be present on the site. Also, A/Es may be best able to identify questionable structural situations such as temporary loadings on the permanent structure or temporary work platforms, provided they are explicitly requested to do so and possess all of the data necessary to perform the analysis. Safety liability associated with shop drawing review is a salient issue within the A/E community, and is likely to be addressed in future revisions to the ASCE Policy Statement 350. The ability of owners to evaluate unsafe conditions is low because they typically lack the site presence and expertise to identify both visible and hidden unsafe conditions.
