Nutritional knowledge as well as economic, social, biological, and cultural factors have been known to determine an individual's food choices. Despite the existence of research on the factors which influence nutrition globally, there is little known about the extent to which these factors influence the food choices of construction workers, which in turn influence their health and safety during construction activities. The present article investigates the extent to which construction workers' nutrition is influenced by nutritional knowledge, as well as economic, environmental, social, psychological, and physiological factors. A field questionnaire survey was conducted on site construction workers in the Gauteng Province of South Africa. Principal components analysis and multiple regression analysis were used to analyze the data. Findings revealed that consumption of foods termed alternative foods including dairy products, eggs, nuts, fish, and cereals, was influenced by nutritional knowledge and resources. Foods termed traditional core foods were influenced by cultural background; foods termed secondary core foods comprising fruits and vegetables were influenced by economic factors, resources, and cultural background; while foods termed core foods were mostly influenced by nutritional knowledge. By providing evidence of the factors which most influence selection and consumption of certain foods by construction workers, relevant nutrition interventions will be designed and implemented, taking cognizance of these factors.

Abstract. The construction industry is well known as a highly risk prone industry owing to the complexity of its activities and dynamic project environments generating an atmosphere of risks that must be taken into consideration in the decision process. For this reason, we have developed this treatise to elucidate the fundamentals of risk management through a concise new proposal of literature review for risk management in construction. Our explanation of this is venture is that over the years, this area has been acknowledged as a crucial process in the business institutions and the most discussed subject among experts and researchers in the construction sector. We have tried in this report to present the most recent studies considering the impossibility to present all definitions of the concept of risk. This study is mainly a literature review; it looks at the literature relating to the concept of risk, risk management in construction as well as methods used in construction industry.

He has worked as a site agent, an estimator, a draughtsman and a lecturer in both Kenya and South Africa. He is currently senior lecturer and researcher at the Durban University of Technology. He has published articles in peer-reviewed academic journals and presented papers at local and international conferences where he received Best Paper awards.

Joint ventures (JVs) have become increasingly common, because of the complexity and challenges associated with the delivery of construction projects globally and in South Africa. However, it has been established that JV projects have experienced unsatisfactory performance leading to clients’ dissatisfaction. The purpose of this paper is therefore to determine the critical success factors (CSFs) influencing the performance of JV construction projects in South Africa. A positivist philosophy position was adopted using a structured questionnaire survey administered to the construction professionals. Prior to the main study, a content validity of the questionnaire was achieved using a pilot study. The data was collected from 115 conveniently sampled respondents, and analysed using principal component analysis and multiple regression analysis. The exploratory factor analysis revealed two empirical models to be tested; namely the first and second order factor models. The result of the first order model revealed that, management control influenced achievement of project objective of JV, whereas, the second order model established that understanding of contractual agreement, which was explained by six components of CSFs influenced achievement of project objective. It is suggested that stakeholders who prefer to be involved in JV projects should acquire good understanding of the contractual agreement in managing JV projects in order to successfully achieve the project objectives. This study adds to the discourse and literature on CSFs of JVs. It provides new empirical evidence of the CSFs that influence project performance outcome of JV in the context of South Africa which can also be replicated in other countries globally. However, the study may not be generalised because of the geographical setting and respondents.

The literature on health and safety (H&S) is bound with different elements and indicators of measuring H&S performance. The purpose of this paper is to discuss the success and challenges of using quantitative and qualitative approach of Delphi technique in validating and identifying H&S performance indicators that small and medium construction enterprises (SMEs) can use to measure and monitor their H&S performance improvement at project level. Furthermore, discuss the identification of experts in the field of H&S, ways of improving consensus analysis and minimizing experts’ non-response. This study is based on practical experience of the researchers pertaining to the Delphi technique method which is a constructivist or interpretive approach to knowledge. The study started with an extensive literature review to identify core elements and leading indicators characterizing H&S culture to develop a Delphi questionnaire that was used in the first round of Delphi. A four round Delphi technique was conducted to attain consensus of the identified H&S indicators. The experts were identified from published articles of H&S, practitioners’ website of H&S and word of mouth. The use of email was used as a mode of communication. This study set to warn but also encourage the use of Delphi technique as a method to unearth information in areas where consensus has not been reached such as H&S performance measurement indicators for construction SMEs in South Africa.
