Housing is a major challenge for most African countries including South Africa which is characterized by numerous backlog of housing provision. This study seeks the adoption of construction 4.0 principles for reducing the housing backlog experienced within the country. Therefore, the study examines the impact of applying construction 4.0 for delivering sustainable and quality accommodation and evaluates the hindrance in its adoption. Construction 4.0 involves the application of industry 4.0 concepts a synonym for the 4 th industrial revolution that originated from the German manufacturing sector to the South Africa housing industry with the intention of creating a digital industry using a sophisticated gadget like drones, RFID, laser scanning, 3D printing and many others. Convenience sampling method was used in obtaining data from practicing construction professional in Johannesburg Gauteng province South African. A total of 184 questionnaires were obtained from the construction professionals out of 220 that was distributed. The data were analyzed with SPSS V 24, using, mean score, regression and factor analysis. The study discovered that there is a positive impact on the use of construction 4.0 principle for housing delivery as it reduced cost and time overrun thereby ensuring the prompt delivery of affordable and quality houses. The foremost hindrance to the adoption of construction 4.0 principle is the cost of investing in modern technology by small construction firms. The study contributes to the innovative ideas for housing delivery in South African it recommends that strategies and infrastructures should be put in place towards enabling the digitization of the construction industry and increase the awareness of construction 4.0 among construction professionals.

The concept of smart cities has become a buzzword in most developing countries. Most professionals within developing countries are quick to adopt this idea in their every day discuss on developing the state of their nation, without actually considering what this concept means to the average individual on the streets. Even lesser consideration is given to the readiness of these developing nations in terms of adopting the concept of smart cities. It is based on this notion that this study, through the review of existing studies, assessed the readiness of cities in Nigeria in adopting the concepts needed for achieving smart cities. The study gives an insight on the challenges impeding the attainment of city smartness in the country. It was observed that solving the problems caused by rapid urbanization within cities is the first step towards making these cities "smart ready". Therefore, if cities in Nigeria are to attain city smartness, first looking inward and solving the endemic problems within these countries is necessary before adopting concepts of smart cities that have been mastered in developed countries. Although the submissions of this paper form part of a much larger ongoing study, it contributes to the body of knowledge as it brings to light the challenges that must be solved if cities in Nigeria are to ever become smart.
