Risk Assessment for Health and Safety (RAH&S) of workers is a complex task that involves the consideration of many parameters that are, quite often, difficult to quantify. RAH&S in the construction industry is filled with inadequate data and/or imprecise and incomplete information, particularly in the design stage - to which traditional quantitative approaches do not have adequate answers. This study outlines the basic aspects for a Qualitative Risk Assessment Model (QRAM) based on elicited data, using fuzzy logic approach. The model was pre-validated in two Brazilian municipalities: Bauru, in the State of Sao Paulo, and Curitiba, in the State of Parana.
