Great discussion, but at the same time a shame that we're having to have. This was an entirely avoidable incident and loss of life.
The oil and gas industry through the IOGP, its industry association, has developed a set of lifesaving rules to protect workers from injury and save lives. These rules while developed for the oil and gas industry have strong applicability to civil engineering job sites. 'Nevers' from this list of rules that apply to civil engineering job sites:

"Conventional failure analysis ignores a growing challenge in the responsible implementation of novel technologies into engineered systems - unintended consequences, which impact the engineered system itself and other systems including social and environmental systems. In this paper, a theory for unintended consequences is developed. The paper proposes a new definition of unintended consequences as behaviors that are not intentionally designed into an engineered system yet occur even when a system is operating nominally, that is, not in a failure state as conventionally understood. It is argued that the primary cause for this difference is the bounded rationality of human designers."
