Abstract: Construction is highly labor intensive and considered as one of the most hazardous and vulnerable industries around the world. Safety perception of all tradesmen, performing different construction tasks simultaneously at the same work-site, has a significant relationship to the occurrence of accidents. Variation in workers perception about safety not only leads to hazardous conditions on work-site but it also results in a situation where a worker may become victim to an accident, whether it happens because of his negligence or his co-workers. To assess the safety perceptions of different tradesmen, a cross-level safety climate questionnaire survey (comprising of forty statements) was conducted on 36 construction sites in different cities of Pakistan. Respondents were belonging to different trades (15) and a good response rate of 73% was achieved. Data were analyzed using system thinking approach and a minimum of three responses were considered for analysis. Results showed that although plasters/painters had clear percpetions for safety but their thinking for safety performance was marginal. Nonetheless Electrician/Mechanicshave opposite opinion. Blacksmith/Welder and Electrician/Mechanic tradesmen have clear safety perceptions in comparison with all others. For cross-level safety climate, most of the workers (except one or two out of fifteen worker types) agree that management acts quickly on safety problems and supervisors are the major source to resolve safety issues. Sixteenassociated perception rules were developed by the application of system thinking on different trademen whichmay help the construction managers to enhance their safety climate by reducing accident rate.
