Evaluating the Impact of Innovative Technologies on the Delivery and Affordability of South African Affordable Housing

The study evaluated the impact of innovative technologies on the delivery and affordability of low-income housing in South Africa. Various technologies, including UAVs, building information modelling (BIM), geographic information systems (GIS), 3D printing, VR, AR, AI, smart sensors, and modular/prefabrication, were explored. A mixed-method approach was used, collecting qualitative data through expert interviews and quantitative data from 100 surveys. Thematic analysis and descriptive/inferential statistics were employed for data analysis. Results showed that these technologies can accelerate housing delivery and improve cost-efficiency. Specific technologies such as 3D printing, modular/prefabrication, BIM, GIS, VR, OOP, and PPM were identified as beneficial for housing planning, design, and construction. Challenges such as high costs and limited social acceptance were also identified. The study emphasized government support through financial incentives and investment in research and development. Promoting the use of these technologies in both affordable and high-end housing projects was deemed important. Overall, the study highlights the significance of innovative technologies in addressing the affordable housing crisis in South Africa and calls for government intervention to overcome challenges and ensure affordable housing for all.
