The purpose of this research study is to assess the impact of the implementation of emerging ICT technologies within the construction sites and offices among Durban South African contractors. The study explores various emerging Information and Communication Technology (ICT) technologies and how they can be used to improve construction project delivery in South African construction industry. The questionnaires were formulated to the evaluate the level of implementation among construction contractors towards advancing their business operations with the emerging technologies presently linked to the Fourth Industrial Revolution (4IR). This study adopted a quantitative research, whilst data collection was done through a questionnaire survey among 145 contractors (105 medium contractors and 40 large contractors) in Durban, South Africa. The data was analysed using descriptive statistics, frequencies and percentages. The data were analysed by employing percentages, mean score, standard deviation, and ranking each question using the SPSS Statistical Package. Findings using Mann-Whitney test, in which the study revealed that the adequate implementation of smart construction technologies embedded in the elements of fourth industrial revolution applications would be significantly beneficial for their overall organisations’ productivity in terms of project design, procurement and construction delivery. The study findings reveal that “electronic procurement (e-procurement), Building Information Modelling (BIM), robotic technology, and “Three-dimensional (3D) technology”, usage of the Internet of Things (IoT), and the utilisation of Cyber Physical System (CPS), and usage of Radio Frequency Identification (RFID) technology were ranked high as most significantly elements of 4IR that would address the potential and actual challenges associated construction, and advance construction project delivery. This study concluded that the implementation of smart construction technologies by the South African construction companies will significantly improve their business performance, construction site operation, office productivity and overall competitiveness of the industry.
