Sustainable Project Management Practices and Environment Performance of Housing Construction Projects in Nairobi City County, Kenya

Abstract

Purpose: The primary objective of this study was to assess the influence of sustainable project management practices on the environmental performance of housing construction projects in Nairobi City County, Kenya.

Material/methods: The study was anchored on Stakeholder Theory and Legitimacy Theory and employed a descriptive survey research design. The target population consisted of project managers or supervisors involved in 71 housing construction projects within the county. A census approach was adopted. Primary data were collected using structured questionnaires. Content validity was evaluated using the Content Validity Index (CVI), while reliability was measured using Cronbach’s alpha coefficient. Data were analyzed using both descriptive and inferential statistical techniques.

Findings: The results revealed that social responsibility practices had a significant positive impact on the environmental performance of housing projects. Additionally, sustainability-oriented resource management was identified as an important factor, although its influence was somewhat less pronounced compared to social responsibility.

Conclusion: The study concludes that the integration of sustainable project management practices—particularly those promoting social responsibility—plays a key role in enhancing environmental outcomes in the construction sector.

Value: This research provides empirical insights into how sustainability practices can be leveraged to improve environmental performance in urban housing projects. The findings offer practical recommendations for stakeholders in the construction industry to strengthen social responsibility and adopt resource-efficient strategies to advance environmental sustainability in project execution.
