- Description: Abstract: The competitive nature of the construction industry (CI) has marginalised health and safety (H&S) on construction projects. Most clients in the CI, if not all, award projects based on price and in most cases to the “cheapest bidder” and not the “safer bidder”. Consequently, such practices have compelled contractors to lower their bid price to increase their chances of being awarded projects, whereas in contrast, H&S is marginalised. The study, which was a case study of nine projects of which six were civil engineering projects and three building construction projects, was purposed to conceptualise a model for pricing H&S on construction projects. The findings showed that contractors do price for H&S using an itemised breakdown even though such items are not included as a trade in the Bill of Quantities (BOQs). With regards to expenditure, the actual costs of H&S ranged between 2.9% and 3.98% for projects with a value below R500 million and between 4.08% and 4.90% for projects with a value above R500 million. Health and safety costs were found to be directly proportional to the projects value and indirectly influenced by the client. Previous studies recommended that H&S should be priced as an itemised trade in the BOQs, but such recommendations are yet to be implemented. The lack of a conceptual model for pricing H&S on construction makes accurate and adequate monitoring of H&S costs unlikely. Thus, a standardised pricing model will assist contractors to price adequately for H&S, and clients, to ensure that provision for H&S measures on construction projects is adequate as required by the Construction Regulations (CR) 2014.

- Description: Abstract: Construction is a dangerous industry globally, with high rates of fatal and non-fatal injuries. However, there is paucity of analytical research that considers the predicators of injuries among construction workers in South Africa construction industry and in the developing countries. The objective of this study was to review existing research literature to identify the variables that are predictors of occupational injuries among construction workers. It also aimed to identify the gaps that exist in the current literature. The review spanned two decades between the periods January 1995 to 2015 and was based on a systematic keyword combination search in two databases that is- emerald a! nd science direct and in google. Twenty one quantitative and mixed method research studies were justified to be relevant for analysis in this current study. They were analysed using thematic content analysis, by identifying themes. All the studies reviewed had different predictors of construction workers injury. Furthermore, no study identified the leadership characteristics of the different construction workers especially the tradesmen, hence these are major gaps identified in the current literature. Despite the gaps identified, five broad themes that are perceived to be predictors of construction workers injuries were identified, these are: work related variables, demographic variables, unsafe health and safety (H&S) behaviour, poor safety climate, and psychosocial factors. This paper finally proposed a conceptual model for construction worker injury occurrence.
