In the previous chapter, an overall sequential exploratory mixed method research design with
an initial qualitative inquiry followed by a quantitative inquiry was adopted for the verification
of the conceptual model and for the assessment of the degree of potential of CPFs to influence
accident occurrence and their associated H&S risk. The findings of the qualitative inquiry
addressing the verification of the conceptual model have been presented in this chapter. The
findings indicate that that the conceptual model is a sound depiction of how CPFs influence
accident occurrence. Regarding how CPFs influence accident occurrence, the qualitative
inquiry has thus shown that CPFs, originating from pre-construction decisions, introduce
certain associated H&S issues (which can be termed as proximal accident factors) into the
construction phase to give rise to accidents. In addition to this path of causation, the process
by which CPFs influence accident occurrence could be marked by causal interactions between
CPFs and proximal factors which could reduce or worsen the presence of the proximal factors
they introduce. By this the qualitative inquiry has given evidence that the mechanism by
which CPFs influence accident occurrence generally reflects the systems view of accident
causation.
