Perceptions of façade risks: a preliminary analysis towards presentation of knowledge graphically

Prevention through Design (PtD) in construction has been identified as an important factor to improve Workplace Health and Safety (WHS). However, challenges exist implementing PtD in practice due to technical, social and regulatory complexity. Moreover, WHS is poorly embedded in curricula of design professionals who generally have limited experience of construction methodologies. Attempts to assist designers with the relevant knowledge in the past have been limited to generic risk assessment guides, sample databases, or static knowledge-based systems. We propose that a graphical knowledge based information visualisation device, an infographic, can cue designers to consider relevant knowledge. Facade design is selected as the case study of the project, which involves the development of an infographic and experimental evaluation to determine its impact. The first phase of the project covered the development of the infographic, however this paper reports the findings related to the second phase of this ongoing project; the experimental evaluation of the infographic. A Q-methodology was selected and administered to a group to determine the subjectivity inherent in facade design risk perceptions prior to the introduction of the infographic to the same group in a workshop environment. 27 participants including designers/architects, engineers, contractors and safety professionals were recruited for the project. Each participant was asked to sort photographs of 16 different facade systems into five categories ranging from safest to least safe. The participants were asked to consider the construction risks associated with the facade design presented in each photo and to provide reasons for their sort selection. Preliminary data analysis of the whole population of data is presented in this paper and a rationale for the common agreements among the whole group is investigated. Further analysis including group-level and detailed quantitative analysis are ongoing.
