The fourth industrial revolution (4iR) technologies offer an opportunity for the construction industry to improve health and safety (H&S) compliance. Therefore, implementing the technologies is of top priority to improve the endless H&S incidents in construction projects, which lead to poor quality of work, late project delivery, and increased labour injury claims. Central to improving the nature of work and other industrial processes, the 4iR technologies have emerged. Concurrent with this trend is the importance of 4iR technologies in enhancing health and safety performance on construction sites. However, the implementation of 4iR technologies in the construction industry is faced with various challenges. Therefore, this paper reports on a study aimed at examining the challenges associated with implementing 4iR technologies in the construction sector in South Africa towards effective management of H&S. The study followed a systematic literature review, data collection using a questionnaire survey and thereafter, descriptive, and inferential analyses were conducted. The findings revealed that the implementation of 4iR technologies is challenged by a lack of adequate relevant skills, the unavailability of training capacities, expensive technologies, and negative perceptions such as fear of job loss by industry professionals. The findings are essential for the advancement of H&S research and implementation. In addition, the findings are important to industry decision-makers in order to elevate their awareness and promote the use of 4iR technologies to manage construction activities. The study implications include the need for the construction industry to collaborate with higher education institutions to conduct research and include 4iR in the curriculum.

The construction industry in South Africa faces challenges with the current payment system used to manage progress payments. Contractors often experience delays in progress payments for completed works. These late payments stem from the improper management of progress payment procedures, namely, information, communication, and collaboration, as well as corruption. This study proposes the integration of common data environment (CDE) as it has emerged central in managing information, improving communication and collaboration in a transparent manner. However, the implementation of CDE is facing challenges in the industry. Therefore, the study aimed at developing a model based on the implementation of CDE to uphold efficiency in the management of payment systems for progress payments. A systematic review was conducted to examine the enabling factors, characteristics of CDE in managing progress payment challenges, and benefits of integrating a payment system in a CDE platform. Furthermore, the study utilised questionnaire surveys to purposively collect data from construction professionals who implemented CDE in their projects. From 201 valid questionnaire responses, a structural equation model was developed; testing for the reliability, validity, model fit, and hypotheses was conducted using AMOS and ADANCO. The findings revealed that enabling factors such as quality technology and quality assurance team are the strongest enablers, followed by training and policy. The findings further predict that CDE integration will improve the management of the payment system by 0.589. The study provides theoretical and practical guidance for researchers, policy makers, and construction professionals seeking to strengthen CDE-based payment system frameworks in South Africa. Furthermore, it is recommended to adopt the method of questionnaire surveys and SEM to validate variables and establish their influence on one another to improve generalisation.
