Analysis indicates the critical importance of these factors in the set of characteristics that describe the causes of accidents in the construction industry. This paper attempts to analyse the characteristics of the construction site to indicate their importance in defining the circumstances of an accident at work. The research was carried out on the basis of data from the register kept by the District Labour Inspectorate in Krakow, Poland. Main substantive tasks include isolating patterns of accidents on site and identifying those of the analysed characteristics that are important in defining these patterns. In terms of methodology, the paper presents a method of analysing data resources by using means of conceptual grouping in the form of cluster analysis.}, type={Article}, title={Cluster analysis in research of accident rate in construction sector}, URL={http://journals.pan.pl/Content/115603/PDF/12_ace-2018-0036.pdf}, keywords={construction site, work safety, accident at work, cluster analysis}, }
