Critical success factors (CSFs) for motivating end-user stakeholder’s support for ensuring sustainability of PPP projects in Nigerian host communities

This is an accepted manuscript of an article published by Emerald in Journal of Engineering, Design and Technology on 06/09/2021, available online: https://doi.org/10.1108/JEDT-04-2021-0202 The accepted version of the publication may differ from the final published version.Purpose: This study aims to investigate two public private partnership (PPP) road projects in Nigeria for exploring factors that can motivate end-user stakeholders for contributing towards sustaining a PPP project in the long-term. Design/methodology/approach: Using a case study methodology approach, this study adopts two-way data collection strategies via in-depth interviews with PPP experts and end-user stakeholders in Nigeria host communities and a questionnaire survey to relevant stakeholders. Findings: The study identifies an eight-factor structure indicating critical success factors for ensuring end-user stakeholders support PPP projects on a long-term basis in their host communities. Originality/value: Results of the study have huge implications for policymakers and project companies by encouraging the early integration of far-sighted measures that will promote long-term support and sustainability for PPP projects amongst the end-user stakeholders.Published versio

Sustainable Construction Practice in Nigeria: Barriers and Strategies for improvement

Purpose: Amidst all solutions posited to address sustainable construction practices in Nigeria, the implementation plans are repudiated by sustainable barriers. This study examines and confirms the strategy with the most significant impacts on the identified barrier to Sustainable Construction Practice (SCP). Design/Methodology/Approach: The study deployed a questionnaire survey to evaluate the perspective of 100 construction actors on the barriers and strategies of sustainable construction practice in Nigeria. Factor Analysis was employed to categorize key barriers and strategies into their underlying clusters for further analysis. Partial Least Squares Structural Equation Modelling (PLS-SEM) was used to confirm the constructs significant relationship and magnitude, thereby establishing the strategies with the highest impacts on the barriers to sustainable construction practices. Findings: The findings revealed three clusters of barriers and four groups of strategies to SCP, including techno-politic barrier, perception and awareness barrier, and sociocultural barrier. For the significant strategies, education and training, stakeholder regulation, incentive support and government and legislative support strategies were established. Overall, education and training strategy was identified as the most dominant and effective strategy to mitigate the barriers of SCP in Nigeria. Originality/Value: The paper establishes education and training as the key strategy to achieving sustainable quest in the AEC industry. The practical implication is that policy makers, educators and professional bodies can harness sustainable knowledge transfer through education and training to improve sustainable construction practices in Nigeria
