Having identified the factors necessary to influence root causes and therefore reduce construction accidents, each factor will now be briefly analyzed as to how it applies to the entities typically involved in construction projects. In other words, this section discusses each entity’s ability to control root causes by analyzing how much the associated factors apply to each entity on a typical project. The analysis will first assume the traditional contractual structure, where the owner hires a general contractor to oversee the construction after he or she has hired an A/E to design the project and to perform traditional construction services. Specifically, it is assumed that the A/E’s construction services include reviewing submittals, responding to requests for clarification, and making occasional inspections to ensure that construction is in conformance with contract documents and that requests for progress payments are reasonable. It is also assumed that the A/E is not responsible for ensuring that construction progress is acceptable, that the A/E does not direct the means and methods, and that the A/E cannot stop the work for any purposes other than conformance with contract documents. How the analysis applies to alternative project arrangements such as design/build is discussed later in the paper.
