- Description: Abstract: This paper presents the findings of an assessment of the possible measures needed for the adoption of three-dimensional (3D) printing for sustainable low-income houses that can be beneficial to the urban poor. The study adopted a quantitative approach and answers were sought from construction professionals actively involved in a construction project in the country. The study revealed through factor analysis that 3D printing for sustainable low-income housing delivery in South Africa could be encouraged through effective promotion and training, government support, improvement of 3D printing technology, and affordability of the technology. The study contributes significantly to the body of knowledge as it reveals the possible measures for improving the adoption of 3D printing in housing delivery in South Africa—an aspect that has not gained significant attention in the fourth industrial revolution and housing delivery discourse in the country.

- Description: Abstract: This study provides a holistic assessment of the current waste management strategies implemented in Nigerian construction projects. The data used in this study were collected from both primary and secondary sources. The primary data were collected through survey questionnaires distributed via emails of the targeted respondents who are construction professionals in the study area of Lagos metropolis, while the secondary data were collected via the review of related literature. Out of the 200 questionnaires distributed, only 168 valid forms were retrieved. The collected data accounted for 84% of the entire survey and were suitable for the analysis. An exploratory factor analysis was conducted while the reliability of the research survey instrument was tested using Cronbach’s alpha coefficient reliability. The result indicated that the waste management strategies were clustered into three groups, comprising practical legal framework and modular construction, sustainable procurement and material optimisation, and proper construction detailing and design. In conclusion, the waste management strategies implemented in Nigeria were assessed as being “not sustainable enough”. However, it is recommended that there is an upgrading in either the approach or method of application of waste management strategies in order to ensure its sustainability.
