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.
